Looking to track your weight for health or fitness? In 2020, we researched over 30 of the best digital scales and then bought 8 top models for hands-on testing. Our testing is thorough, comparative, and without pressure or bias from manufacturers' PR departments. We performed statistical analysis and controlled tests while also understanding how you will actually use the scale you purchase. Our detail-oriented team has summarized their findings in a clear and relevant fashion.
The Best Digital Scales of 2020
Best Overall Digital Scale
Eufy Smart Scale C1
The Eufy Smart Scale was the most accurate performer on our statistical analysis of mass accuracy. Its sensors and app organize a suite of interesting and engaging data. The app is clear, and the device itself is available in two different pleasing and compact visual packages. When we "crunched the numbers" on our objective scoring matrix, the Eufy scored at the top, by far.
The range of tested scales covers a pretty broad spectrum of purchase prices. On that spectrum, the top-scoring Eufy is near the bottom. That it performs so well while also being an excellent value is remarkable. You can pay more a lot more and not get the accuracy and clarity of this Eufy Smart Scale C1. Our only gripe is a minor one. Citizens of the British Commonwealth watch their body mass in "stones". Some scales report in stones (in addition to standard pounds and kilograms), but the Eufy is not one of these.
Friendly on the Wallet
EatSmart Precision Digital
The best we can say about any product that doesn't win our Editors' Choice award is that we considered it for this award. After initial testing and through the remainder of our examination, the Eatsmart Scale was noted as an Editors' Choice in our spreadsheet's award column. In terms of reliability, accuracy, and visual appeal, the EatSmart is right in with the best of the best. If you don't want or need your weight recorded automatically by an app, it is the best.
When you consider the low purchase price of the EatSmart Scale, its performance is amazing. Depending on where you look, and when you shop, the EatSmart can be between 1/10 and 1/2 the price of almost any other competitor in our review. That value comes with limited visual options, but none of our experts found the look to be offensive.
Gives the Weather
Withings Body+ Composition
The Withings Body+ smart scale is clever and comprehensive. Fitness and health experts recommend that you weigh yourself in the morning, after using the bathroom, but before putting on any clothing and before consuming anything. Before putting on clothing is also a good time to check the weather. The Body+ does this for you. It isn't a detailed forecast, but it does give you a rough idea of temperatures, cloud cover, and precipitation. In most cases, that is enough information on which to base any clothing choices left to make.
We like that sort of innovation. It's simple and unobtrusive. Getting weather on your Withings scale requires connecting it to your WiFi network. The upshot of this is that your data is automatically synced to the "HealthMate" app without needing your smartphone right nearby. Everything else about the Withings Body+ works fine, though our team's perception of the appearance of this product varied. All appreciated the very simple look, but some thought it seemed bigger than necessary.
Varied Appearance Options
Taylor Precision Digital
The Taylor 7506 digital scale is widely admired across the internet. We also liked it, and the accuracy is fairly average. Before you get too wound up on accuracy, put it in context. Accuracy is a measure of how closely the logged weight is to actual weight. For most people, in most situations, actual weight is less important (especially when variation in even relatively inaccurate scales is less than 5%) than relative values. You ware watching your weight to watch for changes. If you are using the same scale and using the same weighing procedure (time of day, clothing), you will note any variation in your weight, even if the scale isn't 100% accurate.
What we like best about this Taylor Digital Scale is that the presumably the same electronics and functions are available in different visual forms. You can choose one of three different "looks" and count on the same performance. We didn't like that the screen isn't backlit, as early morning weigh-ins with foggy eyes are easier with some lighting assistance. All the other scales we tested have illuminated on-device screens of some sort.
Best for Calorie Consumption Estimate
The EatSmart Precision CalPal is a sort of hybrid scale. It has more features than a typical basic scale, but it doesn't feature the app or advanced metrics of a "Smart Scale". In addition to measuring and displaying your current weight, this EatSmart remembers some things about you and does some basic calculations. Essentially, you enter your gender, age, height, and activity level and the CalPal calculates your BMI and the number of calories you need to consume to maintain your current weight. You can program four different profiles into the CalPal for four different people.
This scale also measures a greater weight than the other options we tested. All the others top out at or just under 400 pounds. The EatSmart CalPal goes to 440 lbs. The form is larger and less sleek looking than the other options, and set up requires navigating a series of on-device buttons and screen menus. Once set up, it will stay configured until you change the batteries.
Gives a Variety of Data
Renpho Bluetooth Body Fat
The Renpho Bluetooth Smart Scale is compact, slim, and syncs to a smartphone app via Bluetooth. In terms of accuracy, the readiness of the data, and other data features, it competes directly with our Editors' Choice winner. The EC is a little bit more accurate, and most testers liked the look of the Eufy more than that of the Renpho. In all other ways, the Renpho should be considered right alongside our Editors' Choice.
This Renpho is a decent deal. Its price is in line with the other smart scale options, and its performance is better than some of the non-app enabled options. Technological advancements in monitoring health and fitness are surely trickling down to lower-priced options.
Variance in Readings
Bveiugn Body Fat
The Bveiugn Smart Scale is a bargain-basement entry to the field. Many of our top-performing products are very inexpensive; this is a rare category in which the best performers are not even close to the most expensive. As compared to the Editors' Choice Eufy Smart Scale, the Bveiugn is a few dollars less. That might be enough to tip the balance, so to speak.
The budget level price of the Bveiugn comes with some trade-offs. In our accuracy testing, we found readings on the Bveiugn to be all over the place. First, you must stand more still on the Bveiugn than on the others. Next, readings differ from actual by sometimes significant amounts. There is more error on this scale than on others we tested. In the realm of pure subjective examination, it is worth noting that we were unable to find any web presence for a company called "Bveiugn". Everything we know about the product comes from its packaging and retailer's sites. This isn't inherently bad, but it is somewhat weird. How will the service, sales, and ongoing quality control be for a product made by a company that doesn't have a simple website?
Simple and Inexpensive
Etekcity Digital Body Weight
Etekcity's scale is simple and clean. When you stand on it, it quickly records your weight and communicates it to you with blue, backlit numbers that are just under an inch tall. You remember or note your weight manually, and come back again at whatever interval you choose.
The price is right, and we found it to remain reasonably accurate through our test period and across a range of tested weights from 20 lbs to 230 lbs. Etekcity tells us that it will work up to a maximum weight of 400 lbs.
Why You Should Trust Us
To evaluate and review digital scales, we apply our familiar, rigorous, and comprehensive testing regimen. We performed accuracy tests with weights of known mass across a wide range and then performed statistical analysis on the data to reinforce our findings. We used each scale daily for almost a week to see just how useful and usable the data and interface is. Long time team member Jediah Porter oversaw testing and review writing. Jed is a life-long health and fitness practitioner and the ultimate exponent of living a "quantified life". He keeps spreadsheets of his own health and fitness metrics and has for decades. He understands what makes that pursuit easier and what isn't required.
Analysis and Test Results
We examined data readiness, aesthetic nature, accuracy, and availability of other types of data for every tested body weight scale. We compared them to one another, which you can't do, and used each in the context of health and fitness monitoring and improvement just like you will.
Basically, how usable is the measurement or measurements made by each scale? To assess this metric, we examined app integration (when available), display size and lighting, and the types of units each scale generates.
Having an app to automatically record what your scale measures is the biggest data readiness advantage. With an app, you can step on the scale first thing in the morning, before coffee or clothing or food, and then move on. The scale and app work together to log the data, and then you can review it at your leisure and in a way that allows you to track trends etc.
We tested four scales that include app integration. This list of so-called smart scales, unsurprisingly, top our entire chart but are, on average, more expensive. The Eufy C1, Withings Body+, Renpho Bluetooth, and Bveiugn Smart Scale all send your weight and at least some other data to a smartphone app in one way or another. None of the others employ apps.
The size and lighting of the on-device display also affect the utility of the data captured. If your weight is displayed, but you can't read it, it is not that useful. All but the Top Pick Taylor Digital Scale feature lit displays, and the Best Buy EatSmart Scale has the largest numbers on its display. Three of our four award winners have display numbers greater than one inch in height. The Withings Body+ has weight numbers that are only 0.6 inches tall. This one displays more information on its screen (including today's weather forecast!) than any others, but the size of the weight numbers suffers as a result.
Finally, in terms of data readiness and usability, let's talk about units. Each scale we tested communicates in both pounds and kilograms. This covers most of the users around most of the world. Certain areas, generally those with extensive British influence, use "stones" as a unit of body weight measure. Not all scales include the display of stones. Tested scales from Withings, Renpho, Bveiugn, and EatSmart display your weight in stones. The rest do not.
For 99.99% of its life, your scale will sit in your bathroom or bedroom closet unused. For it to be used, it must be handy. For it to be handy, it must be visible. If it is going to be visible and largely unused, it must be visually appealing. We assessed visually appeal almost entirely subjectively, and simply had each of our testers rank them. Between testers, aesthetics rankings were not unanimous but came close, and we were able to identify clear patterns. The simplicity of appearance was held to a high regard.
After subjectivity assessment, we gave a bump to those scales that have visual options. For most, this means two different colors. The Withings, Renpho, and Eufy scales are available in black or white color schemes. The Top Pick Taylor Digital Scale is available in three different design schemes. The Bveiugn, Etekcity, and EatSmart scales are only available in one look.
Subjectively and averaged for the preferences of the whole test team, we ranked the scales in this order, from prettiest to least: Eufy, EatSmart basic, Withings, Bveiugn, Taylor, Renpho, EatSmart Calpal, Etekcity.
First, the scales we tested varied very little from one another. The maximum variation across the range of tested scales was never more than a couple of percentage points. Next, how important is accuracy? You will use your scale to watch patterns in your body weight, and you need to know what you weigh today relative to yesterday or a year ago. As long as you keep clothing and time of day consistent, you will learn what you need if the scale's numbers vary from your actual mass.
Nonetheless, we tested for accuracy. Best would have been to test each scale with a range of known weights. Given how inherently accurate the scales are, securing known weights across a range was impossible. Whether we used weightlifting plates or water, we found more variation in the test weights than we did between the scales.
Therefore, calculating accuracy was purely mathematical. We took four different measurements with each scale, across a range from 20 lbs to 230 pounds. Assuming that variation was not systematic, we took the average measured weight to be very close to the true weight. We assessed each scale's average variation from that actual weight. In doing so, we found some patterns.
Wihtout a doubt, the Editors' Choice Eufy Smart Scale C1 is the most accurate. On the other end, and backed up by anecdotal observations while testing, is the Bveiugn Smart Scale. We found the Eufy to be 8x more accurate than the Bveiugn. Again, though, different clothing or slightly different hydration strategies will yield greater weight differences than you'd see on these polar opposites.
Every scale we tested measures your weight, but some do at least a little bit more. The EatSmart basic, Etekcity and Top Pick Taylor scales do nothing more than monitor your weight. The EatSmart CalPal measures your weight and also calculates your "Body Mass Index"; it estimates the number of calories you can consume each day to maintain your current weight.
The so-called "smart scales" all have apps, and all take some additional measurements. Virtually all the additional measurements that a smart scale captures are deduced from a measure of your body's resistance to a very faint (undetectable) electrical current. None of this data is as accurate as its more directly measured counterparts, but all different things that a smart scale attempts to communicate are deduced from the same resistance measurement.
Body metrics that smart scales report include, but are not limited to, body fat %, BMI, bone mass, body water %, skeletal muscle mass, body age, subcutaneous fat, and visceral fat. These are interesting and all completely intertwined. Basic weight measurements are the most valuable of all data collected by a scale.
The Top Pick Withings Body+ smart scale adds yet another attribute that none of the others have. Provided you connect it to your WiFi network, the Withings will show you a basic weather forecast for the day. If you, as you should be, are weighing yourself before clothing or food or drink for the day, this little bit of info can help guide your wardrobe choice. This is neat, and we found it handy. You might also.
Effective monitoring of your body weight requires a good scale. Your choice of a scale informs your ultimate success in watching your weight. We've watched our weight and watched the scales, and trust that our review efforts will help you choose the best tool for your purposes. Our critical approach considers objective differentiation between products and a thorough understanding of how real world application occurs. We trust our recommendations and realize that there is something on the market for everyone.
