The Best Bathroom Scales

Bathroom scales need to do one thing: Give you a weight measurement you can trust. After more than six months of researching and stepping on and off 11 scales (a total of 35 hours and more than 550 weigh-ins), we found the EatSmart Precision CalPal to be the most accurate and precise basic digital bathroom scale with one of the easiest to read displays.

This month: We’re beginning testing to compare three popular and widely available scales—from Etekcity, Famili, and Zerla—against our current picks. But we remain confident in our current recommendations, and we don’t expect this new testing to change our advice dramatically.
Three months ago: We’ve broken ‎smart scales out into its own guide.
Three months ago: Our pick for best smart scale, the Withings Body, has been rebranded as the Nokia Body+ following a recent merger between the companies. This new version includes a few minor updates, and although we haven’t had a chance to test this new version, we stand by the recommendation.
Five months ago: We added a new runner-up for best smart scale, and added a smart scale and a basic scale to the competition section.
One year ago: We’ve changed our upgrade pick to the Withings Body, the updated version of our previous upgrade pick, the Withings WS-50. We’ve tested the Withings Body for two months, and it provides the same features that made our previous pick so successful.
One year ago: Withings has released two new versions of our upgrade pick—the Withings Body and Withings Body Cardio. These scales provide the same features that made our current upgrade pick, the Withings WS-50, so successful and add some new tricks as well. We hope to have both the Body and Body Cardio in for testing as soon as possible, but in the meantime we’ve added what we know so far about these new scales to our What to look forward to section below.
One year ago: Our top pick—the EatSmart Precision CalPal—is back in stock on Amazon.
One year ago: The EatSmart Precision CalPal is once again unavailable on Amazon. A spokesperson told us it will be back in stock in late May. But two variants of our runner-up pick—the Taylor Glass Digital CalMax—are in stock, including an all-glass version that is nearly identical to the CalPal but lacks a backlit display and runs on a lithium battery instead of AAAs.
Two years ago: The EatSmart Precision CalPal is once again unavailable on Amazon.

Our pick
EatSmart Precision CalPal
Of the inexpensive, basic digital bathroom scales available, this was the most accurate and precise model we tested. It weighs you every time rather than pulling a reading from memory.

The EatSmart Precision CalPal has a comfortable, wide platform and is attractive enough to leave out on your bathroom floor. Most important, the scale detects changes in weight of a few tenths of a pound, whereas most other scales will only respond reliably to a weight change on the order of half a pound, or will even pull your weight readings from memory without trying to measure you.

Our pick for best basic digital scale offers the essential features most people need in a scale—and then some. It’s comfortable to stand on, the backlit display is one of the largest available (3.5 inches), it has a 440-pound weight capacity, and it turns on and off instantly. Weight readings are accurate and sensitive, detecting weight changes up to 0.4 pound when other scales couldn’t. The scale is backed by a confidence-inspiring two-year warranty, too. Also, although it’s a relatively inexpensive bathroom scale, the EatSmart CalPal offers a few more features than just your weight reading, including last reading and memory for up to four people.

If you can live without a backlit display, or if you’re not a fan of the EatSmart CalPal’s glass platform, the Taylor Glass CalMax does almost everything the EatSmart CalPal can do. You’ll trade the convenience of using AAA batteries for the Taylor’s lithium battery and give up a backlit display, but if you’re concerned solely about getting an accurate weight reading, the Taylor Glass CalMax won’t disappoint. For most of our tests, the EatSmart CalPal and the Taylor Glass CalMax offered the same accuracy and precision we’re looking for in our bathroom scale, although our top pick was more accurate than the Taylor Glass CalMax in a couple of our tests.

Why you should trust us

To select our scales for testing and come to these picks, we interviewed several health and fitness experts, including Dr. Linda Everett, a bariatrician (a physician who specializes in weight loss); Kusha Karvandi, a certified personal trainer and founder of Exerscribe; Beth Skwarecki, a health writer; and Rachel Pires, author and weight loss counselor. We also read hands-on tests and reviews from Consumer Reports  (subscription required), Good Housekeeping, Live Science, and similar outlets. Additionally, we spent hours poring over individual scales’ customer reviews on Amazon.

Who should buy this

Several bathroom scales, all turned off, scattered atop wood floor.

Just about everyone could benefit from a good bathroom scale. There’s a reason you’re weighed at every physical exam: Being over or under healthy weight recommendations is linked to a greater risk for health problems. Significant weight changes can tip you off to health or lifestyle changes that need your attention. Even simply monitoring your weight could be beneficial in the long run: Several studies, including the one done at the comprehensive National Weight Control Registry, have found that one of the most common characteristics of people who lose weight and, most importantly, keep it off for years afterward is regular (at least weekly) weigh-ins. As the saying goes, you can’t change what you don’t measure. Weight gain is often also very subtle, so we’d say you don’t notice what you don’t measure.

Rachel Pires, author of Diet Enlightenment, said weighing yourself can help you keep a weight-loss plan on track. “Overall, when you see how effectively you’re losing weight each week, and you have confidence in your plan, it helps you stay on track long-term.”

If you (and your physician) find your weight measurement helpful in progressing toward better health or maintaining the health you have, great—the bathroom scale can be a useful tool.

That said, weight is not a perfect self-contained measure of overall health. Your weight fluctuates throughout the day by between one-tenth of a pound and a few pounds, due to variances like your hydration, when you last ate, and even what you recently ate. “As long as you don’t become overly fixated with the number on the scale, the advantages to using one definitely outweigh the disadvantages,” Pires said. If you (and your physician) find your weight measurement helpful in progressing toward better health or maintaining the health you have, great—the bathroom scale can be a useful tool. The number alone, however, isn’t something to obsess over, and is just one metric of many that can inform your understanding of your body.

The best smart bathroom scale

Looking for a scale that will seamlessly sync your progress to an app? Our smart-scale pick is the most accurate scale, period, plus it will automatically reveal weight and body-fat trends.

‎Smart scales can be more than four times the price of regular digital scales. They aren’t necessarily better than all the other digital scales—they just have more connectivity features. More-advanced digital bathroom scales offer more insights into your health, such as an estimate of body-fat percentage, now considered a better indicator of health than weight alone or BMI (an estimate of body-fat percentage based on weight and height). Only a handful of basic digital scales offer body-fat or other body-composition (e.g., bone-density) readings, so if you want a body-fat percentage estimate, you’ll need to invest in a smart scale. There’s another important reason you might want to spend more on a smart scale compared with one that doesn’t connect to your phone or sync your data online: effortless weight tracking. After jotting down weight readings for a dozen scales over a couple of weeks, we quickly realized the benefits of having a smart scale automatically do the tracking. Gathering that data didn’t take any thought or leave room for error, and it’s one less barrier to regularly monitoring your weight, which is already enough of a hassle for most of us.

How we picked

Four bathroom scales -- one black, one glass, one silver, and one white -- on wood floor.

The two most important qualities in a scale are accuracy (the scale correctly reads your exact weight changes) and precision (the scale gives the same reading if you do two or more readings in a row). First and foremost, you want to be able to trust the reading. Precision and accuracy, however, are things we could only measure ourselves through hands-on testing, so to narrow the vast universe of digital bathroom scales before we got to that step, we turned to several sources.

Our survey of Wirecutter readers (more than 600 responses) helped us find out the features people want most in a scale—beyond accuracy and reliability, things like a large backlit display, an aesthetically pleasing design, tracking weight history, and being able to sync weight data to their phones. We combined that with recommendations from our experts, editorial and user reviews, and the scales’ price, design, and features.

A great range of bathroom scales are available, from the no-frills kind that just show you your weight to ones that seem to want to measure everything possible. And, as we learned from stepping on scales hundreds of times in the last couple of months, not all scales feel the same when you weigh yourself.

After accuracy and precision, we looked at usability elements like maximum weight limits, platform size, display size, and what it was like to actually use the scale. We looked for scales that had a comfortable, wide platform, scoring scales lower that were 12-inch squares when others’ platforms were closer to 13 inches. Readability of the LED display is also important: Some scales had 3.5-inch blue backlit displays that made getting the weight reading somewhat more pleasant, compared with 2-inch non-backlit displays. We also preferred scales that used AAA batteries (rather than less-common-around-the-house lithium batteries) and also scales with weight limits more than 400 pounds versus those that maxed out in the 300s.

We decided to eliminate analog or mechanical scales (the kind with a dial) from consideration entirely. Mechanical scales have been shown to be significantly less accurate and less precise than digital scales, and ConsumerSearch says that analog scales’ delicate internal framework—small mechanical parts such as tiny springs—makes these scales vulnerable to wear and tear as well as misalignment. Mechanical scales also show weight increments of only 1 pound, can be hard to read, and need to be set to zero and recalibrated manually. They’re also a dwindling category: When we first searched for scales to test, only 45 bathroom scales on Amazon were mechanical, compared with 665 digital bathroom scales.

Many bathroom scales can now do much more than simply weigh people. Because weight trends over a month or so are more helpful to understanding your weight than any single day’s weight measurement, tracking weight history, estimating body-fat percentage, and recording weights for multiple people are the features that our experts recommended we look at in a bathroom scale—features we looked for in both smart and basic bathroom scales, if available.

Many home scales now attempt to measure body fat—a measurement some people are interested in but not everyone wants (another number to obsess over). Those who do want it should note that measuring body fat is complex, for a couple of reasons.

Previous studies, such as one done by Consumer Reports (subscription required) in 2010, have found that body-fat measurements from consumer bathroom scales aren’t all that accurate. Berkeley Wellness explains that scales that measure body fat through your feet rely on bioelectrical impedance, which sends a small (painless) electric current up your legs. Muscles contain more water than fat does, and thus conduct electricity better, so the scale calculates your body-fat percentage based on your body’s resistance to that current and other data you enter into the scale (height, age, and gender, plus the scale’s measurement of your weight). Scales with only foot electrodes—as most bathroom scales that measure body fat are—tend to underestimate body fat in people with lots of it and overestimate it in leaner people, a 2008 study published in Obesity Facts found.

“While the body-fat readings in scales aren’t perfect, they are more accurate than calipers,” said Dr. Linda G. Everett, a medical weight loss physician in Philadelphia. Readings can vary by water retention and even the clothes you’re wearing, so “getting a baseline from your doctor is a good idea if they are using a medical grade body composition scale,” she said.

“While the body-fat readings in scales aren’t perfect, they are more accurate than calipers.” —Dr. Linda G. Everett, medical weight loss physician

Some scales, both basic and smart, added other features that we didn’t consider important, such as providing calipers and a tape measure along with the scale or calculating BMI. You can calculate BMI yourself easily with an online calculator, and as reported in The New York Times (now the parent company of Wirecutter) in 2015, BMI can be misleading. These are features we simply ignored, focusing on accuracy and precision, usability and design, price, and smart features.

After eliminating scales that didn’t fit our criteria from each category, we had a manageable six bathroom scales to test across both smart and basic categories.

How we tested

We set up all the scales in one room according to their manuals and calibrated them as instructed. Then Melanie weighed herself a ridiculous number of times over a three-week period.

On each day’s test, Melanie stepped on and off each scale three times, noting if her weight changed within those few minutes to test for the scales’ precision (consistency between readings). And then she weighed herself four more times on each scale with a 0.4-pound book, a 0.6-pound book, the two books together (1.0 pound), and a 10.1-pound dumbbell, sometimes switching the order of the weights to check differences between weight gains and weight losses. We weighed the books and the dumbbell at the post office so we could be sure of their weight accuracy (we’re told the post office calibrates its scales daily). For updates to this guide, we used shoes of different weights and a 5-pound dumbbell.

All in all, Melanie weighed herself on each scale at least 40 times (more for the scales that ended up being our top picks).

What we learned is that scales often offer a seemingly manufactured sense of precision and accuracy: They may calculate your weight based on your previous readings rather than actually weighing you each time.

Scales often offer a seemingly manufactured sense of precision and accuracy: They may calculate your weight based on your previous readings rather than actually weighing you each time.

For example, after weighing herself, then weighing herself again while holding a 10-pound dumbbell, and then weighing herself yet again without the dumbbell, one of the scales said she weighed 10 pounds more than she did. Other scales would at first correctly show the additional weight difference when she was holding one of the books, but would then revert to her previous weight measurement without the book. Although some scales read her weight nearly instantly, the downside is that they often seemed to be pulling from memory, whereas scales that took a few seconds to display the weight reading actually measured weight each time. We requested comment from the companies that made the offending scales, but they were not forthcoming with an explanation.

We gave each scale a 0.2-pound margin of error. So, for example, if a scale weighed Melanie at 120.0 pounds and she then got back on the scale with a 0.4-pound book, we considered the scale to be accurate if it said she weighed anything between 120.2 to 120.6 pounds. Most scales show weight in increments down to one-tenth of a pound, so it was surprising to see that most of them really weren’t that sensitive. We considered a scale precise if it gave us the same number three times in a row with no margin.

With 12 scales laid out on Melanie’s dining room floor, it was also impossible for friends and family members who came over not to try them too. So over the course of testing, eight other people—from her fourth-grade daughter’s 60 pounds to her big-and-tall friend’s nearly 400 pounds—also stepped on and off the scales and gave us their opinions of the scales’ designs and usability.

The best basic scale: EatSmart Precision CalPal

The EatSmart Precision CalPal Digital Bathroom Scale on wood floor. Its body is transparent glass with black edges, and its digital display is a glowing blue with black numbers.

Our pick
EatSmart Precision CalPal
Of the inexpensive, basic digital bathroom scales available, this was the most accurate and precise model we tested. It weighs you every time rather than pulling a reading from memory.

The EatSmart Precision CalPal was the most accurate of the six basic scales we tested. It saves up to four user profiles and can weigh people who are up to 440 pounds (a much higher range than most basic scales). And a few small details make the scale easier to use than others we tested.

The EatSmart could detect when our tester held the 0.4-pound book in all but two of the rounds (within a 0.2-pound margin of error) when other similarly priced scales didn’t. The rest of the scales more often than not ignored that weight change. The EatSmart was also reassuringly precise for each test: When our tester weighed herself three times in succession, the readings were always the same.

The EatSmart Precision CalPal has a comfortable platform and a display that won’t leave you squinting. That blue backlighting makes a small but noticeable feel-good difference compared with scales without the color or backlighting.

The EatSmart CalPal maxes out at 440 pounds, far more than most scales’ limits of 400 or even 350 or 300 pounds.

The EatSmart can save up to four user profiles, and it will detect who you are based on your weight as long as two or more users aren’t within 6 pounds of each other. Once you save your information (entering your height, weight, gender, and activity level), the scale will remember you every time you weigh yourself and let you see your last weight with the memory button.

This scale maxes out at 440 pounds, far more than most scales’ limits of 400 or even 350 or 300 pounds. Whether you’re near this weight maximum or you want to weigh yourself with your luggage, capacity makes a difference. The scale also has a big, easy-to-read blue backlit display and, with a two-year warranty, double the typical warranty length of most bathroom scales.

Besides the basic specs, though, there are a couple of small details that make this scale stand out among other basic scales. It lets you know when it’s got your reading by flashing three times before settling on one number, and it continues to display that reading for about half a minute after you get off the scale. That might not sound like a big deal, but if you’re logging your weight manually (as you must if you don’t have a smart scale) or trying to get your reading with your luggage but can’t see the display while you’re standing on the scale, that extra time to see your weight is very helpful. (By contrast, the GoWise scale would quickly turn off even while our tester was still standing on it!)

The EatSmart Precision CalPal is an upgrade to the EatSmart Precision Digital scale we chose as our top pick in 2013. It has a higher weight limit, a better backlit display, and additional features for the same price.

Flaws but not dealbreakers

The glass platform: You either love it or hate it. Most of the people who tried the scales for us were hesitant to use the EatSmart Precision CalPal because of its mostly glass platform. Although made of heavy, tempered glass, it looks less sturdy than the other scales because it’s mostly see-through and the glass platform is thinner than the other scales’ enclosed full bodies. (Other scales measure 2½ centimeters in height, from the floor to the top of the scale; the glass platform part of the Precision CalPal is about half a centimeter tall—still plenty thick but possibly off-putting for some.)

It might look very thin from some angles, but the glass platform measures about half a centimeter tall.

The curved sides also make the scale feel smaller, or at least narrower, than other fully square scales, even though it’s a roomy 12½ inches wide at its thinnest and 13 inches wide at its widest. Some people might prefer its less-boxy shape and the way the glass blends in with any bathroom decor. (As Melanie retested this scale before writing up her test results, her husband remarked, “This is a nice-looking scale,” which says a lot considering she had 11 other scales taking up their dining room over the course of a few months.)

It takes a few seconds longer to get a reading on the Precision CalPal, which was acceptable for us because the readings were consistent and accurate for the most part.

In addition to your weight, the EatSmart Precision CalPal also measures your BMI and how many calories you should consume in a day if you want to maintain your weight. For most people looking for a basic digital scale, these are probably unnecessary features. We dispensed with the value of BMI measurement above, but your caloric needs can vary greatly depending on your body composition, activity level, and goals; if you want a change, it’s best to do some research and consult with your physician.

Runner-up basic scale: Taylor Glass CalMax

The silver Taylor Glass Digital CalMax scale on a wood floor. The scale's edges are slightly curved -- outwards at the top and bottom, inwards at its sides.

If you want to save a few bucks, the Taylor Glass CalMax is your next-best bet. Manufactured by the same company as our pick, Taylor, the CalMax offers some features that are identical to those in the Precision CalPal, including 440-pound weight measurement, 0.1-pound weight increments, and a 12-inch platform. But unlike the CalPal, the CalMax cannot recall the last weigh-in, does not have a backlit display, and uses a lithium battery instead of AAAs.

Again, for some people the all-glass design of the EatSmart Precision CalPal can be off-putting. If you don’t like so much glass, note that the CalMax comes in two variants, one with see-through glass and the other with a silver backing that gives the appearance of being more solid from above. Although we don’t see any risk of breaking through either of the glass faces of these models, sometimes the illusion of backed glass is enough to calm some people’s fears. A silver backing also helps to hide smudges from dirty feet.

The CalMax display is nearly identical to that of the CalPal except it has no backlight, which makes it difficult to read in low-light situations.

Functionally, in our tests the CalMax was just as precise as the CalPal and nearly as accurate (it didn’t detect weight changes of 0.4 pound in a couple of tests). If you can live without a backlit display and weight tracking, this model is a basic digital scale that’s more accurate than most. It also has an unusually long five-year warranty.

The competition

The Ozeri WeightMaster II gives your current weight, then cycles through your previous day, last three days, previous week, and previous 30 days, using red or green backlighting to show you if you gained or lost weight. Some testers who tried it appreciated the scale’s no-frills, anti-slip design. Though it detected the 0.4-pound change in one of the tests, more often than not the scale would detect only weight changes of 1 pound or more.

The BalanceFrom High Accuracy Premium Digital Bathroom Scale will remind you of your last weight measurement (mercifully, it shows you the last weight in green backlighting, rather than red for bad or green for good). However, it detected only changes of at least 0.6 pound and was inaccurate sometimes by 0.3 pound. And its 12-by-12-inch platform is the smallest of the bunch—much less comfortable to weigh yourself on than the larger platforms despite that big display.

The GoWise USA Slim Digital Bathroom Scale’s performance was very erratic: For one test, it accurately detected every weight change (reading 0.4 pound, then 0.6 pound, and more when our tester held those weights), but on other days it didn’t detect any weight change at all when she stepped back on the scale with the weights.

The Balance Basic Bathroom Scale’s platform is smaller than those of our favorite basic scales (11.8 by 11.8 inches), and it measures weight in 0.2-pound increments, a lower resolution than our favorite scales. The weight limit is 400 pounds.

The Ozeri Precision II did not consistently detect weight changes when our tester held or removed additional weights.

In a buying guide last updated in March 2013, Consumer Reports really liked the Taylor 7506, but it reads as an outdated and subpar model by our standards: 0.2-pound increments versus the 0.1-pound increments we looked for, a small 11.75-inch-long platform, and no backlighting. The display is also small, at 1½ by 2 inches.

The Etekcity Stainless Steel Digital Body Weight Bathroom Scale has a small surface that was a little slippery when we stepped on it with sweaty feet (let alone wet feet).

The Famili 271B Digital Body Weight Bathroom Scale and Zerla Digital Bathroom Scale have high ratings on Amazon and are less expensive than the competition. However, both failed to consistently detect a change of 0.8 pounds, making them not as sensitive as our picks.
