The best smart scales make for a comprehensive overview of your health, whether you're hoping to gain weight, lose weight, or just stay at a healthy ratio of fat to muscle. They're useful for pregnancy, medical conditions, serious fitness enthusiasts, and everyone in between.

In contrast to your standard analog scales, smart scales are clever pieces of tech that can give you insights into your muscle mass, fat percentage, and even the weight of a baby or pet, as well as basic stats like overall body weight. This is all done by biometric impedance analysis (BIA), which involves sending a small electrical current through to different body parts. From there, the smart scales use data from the speed of each current to differentiate between the readings.

It’s very easy to learn how to use a smart scale. Most of them give you your stats simply by you stepping on them, once you've set them up. Most can connect to an app, via Wi-Fi or Bluetooth, and add your measurements to ecosystems like Fitbit, Google Health Connect, or Garmin Connect automatically. You can even set up different family member profiles, to make sure everyone has the correct weight and height inputs.

Now updated to include our new budget pick, the excellent $20 Vitafit Smart Bathroom Scale, here are the best smart scales you can buy in 2024.

The Xiaomi Mi Body Composition Scale 2 takes our number one place as the best smart scale you can buy today. Not only is it a breeze to set up, it also delivers accurate and consistent body composition data that you can track easily in the Mi Fit smartphone app.

The design is sleek and minimalist, the display (which only appears when the scale is in use) is bright and easy to read while standing up, and the non-slip glass platform feels sturdy and stable underfoot.

In our tests, we were particularly impressed by the simplicity of the whole process. If you only want to see your weight then no setup is required at all, but the scale allows up to six people to keep profiles with comprehensive stats including fat and muscle mass, BMI, and even estimated basal metabolic rate.

Your weight and body composition stats will sync with Google Fit, Apple Health and Samsung Health automatically, and if you own a Xiaomi fitness tracker like the Mi Smart Band 6, it's even easier to recommend, as all your health and wellbeing data will be gathered together in one place.

We were blown away by the accuracy of the Vitafit Smart Bathroom Scales in our review, considering its incredibly cheap price tag. For a $20 smart scale, the Vitafit is very well built and sturdy, with a sleek design that will look right at home in your bathroom.

It's accompanying app is snappy and helpful, displaying lots of important information in the blink of an eye. Seamless connection is supplied by Bluetooth, and the app works on iPhone or Android.

It'll show you important metrics like weight, BMI, bone mass, basal metabolic rate, and more. It's got a generous weight limit of up to 180kg/400lb and support for limitless numbers of users. There's also functionality to weigh babies and children, so it makes a great scale for the whole family.

It's not perfect, and some of the body composition measurements lack the accuracy of more expensive alternatives, but at this price, it's hard to argue with as a budget pick.

Not the cheapest option

The Withings Body Scan smart scales has all the basic features and more, showing you simple metrics such as basal metabolic rate, your vascular age, or more esoteric info such as pulse wave velocity.

Though it comes with an eye-widening price tag, it's a fantastic model if you want to take a deep dive into your body stats, and ideal for families with space of up to eight profiles. One of the most impressive features of the Withings Body Scan smart scales is its segmental body composition analysis, stretching across six separate areas including muscle mass and water mass.

But it's the accompanying Withings Health Mate app that takes the smart scales to the next level. When set up, the app does more than show your stats, providing guides that explain what your measurements mean if you're unsure. In addition to reading your measurements, the app will take your stats to identify changes and keep you updated on which direction your health journey is going.

Aside from its complex features and in-depth analyses, the scales are very simple to use and show you everything you want to know on the display screen during casual weigh-ins. They also adopt a slick and modern design, with a useful handle that acts as a wall mount.

The Withings Body Cardio is the company's most advanced smart scale. Not only does it give an accurate measurement of your weight, muscle mass, body fat and so on, it can also provide an indication of your overall cardiovascular health, and help you take action to improve it.

The scale can measure both standing heart rate and pulse wave velocity. A lower heart rate is generally a sign of better fitness, while pulse wave velocity indicates how flexible your arteries are. Stiffer arteries mean your heart has to work harder to pump blood around your body.

If that sounds confusing, don't worry – it's all clearly explained when your data is synced with the Withings Health Mate app (via either Bluetooth or Wi-Fi). together with practical advice to help you improve your readings.

This isn't a scale you'll want to be carrying often (it's much heavier than the others in this listing), but its two-layer design with no feet means it can be used on any type of floor. That's a real win if you want to weigh yourself in a carpeted bedroom – electric scales are usually only suitable for hard floors,

This is a premium scale, and has a price tag to match, but if you're interested in making long-term changes and improving your fitness rather than just losing weight, it could be well worth the investment.

5. Eufy Smart Scale P2 Pro

The best smart scales for added features

Specifications

Size: 280 x 280 x 26 mm (11.0 x 11.0 x 1.0 inches)

Water rating: IPX5

Connectivity: WiFi and Bluetooth

Maximum user weight: 180 kg

16 different metrics measured

+

Can weigh pets and babies with it

Reasons to avoid

-

Fat, resting heart rate and BMR readings are way off

-

Trends only available for four metrics

Eufy's Smart Scale P2 Pro is a feature-rich full-body monitoring system that can measure 16 different metrics for multiple members of your household, including pets and babies. But this smart measuring device can do more than just measure weight and body fat – the P2 Pro can also measure resting heart rate, protein percentage and body age, among other things.

But wait, there is more! Via the EufyLife app, you can also log your food intake – just like in MyFitnessPal – and set goals, create weekly/monthly reports, check daily/weekly/monthly/yearly trends and more. Needless to say, the more you use the scale, the better, as frequent measurements will help the app and the scale build a more accurate picture of your body.

Sadly, not all measurements are accurate, especially fat calculations. During our testing, both visceral and subcutaneous fat levels were reported as high, despite the overall body fat level being in the normal range. Even more strangely, this overall fat level was also much higher than expected; our reviewer had a DEXA scan done and been given a fat score of 12% three months prior to testing the Eufy P2 Pro, yet the scale said he had 21% body fat – and that's without any visible changes in physique.

Resting heart rate and, therefore, basal metabolic rate (BMR) measurements also seem off. Nevertheless, we enjoyed using the Eufy P2 Pro, and considering the low price, it's easy to look past the scale's flaws and appreciate its many useful features. The P2 Pro might not be the best smart scale on the market, but it's worth the money – not to mention, it syncs with third-party apps such as Apple Health, Google Fit and even Fitbit.

Expensive

The Garmin Index S2 is another Wi-Fi-enabled body composition smart scale, that delivers accurate, consistent results. Its screen is particularly high resolution, which allows you to see detailed graphs of your weight over time.

Data from the scale syncs with the Garmin Connect app, which you'll already be familiar with if you own one of the company's running watches or fitness trackers, allowing you to see all your health data in one convenient place. Garmin Connect also synchronizes with a bevy of third-party fitness and diet apps, including MyFitnessPal, Nike+, and Noom to name just a few, so you don't have to enter data from your weigh-ins manually.

We'd appreciate a little more context around each of the metrics shown in the app (for example, it would be helpful to know whether your muscle mass is normal for your age and gender, and how close it is to the boundaries) but this is nevertheless a great smart scale if your budget will stretch to it.

How to choose the best smart scales for you

The top smart scale for your needs is likely going to be the one that suits your lifestyle. Firstly, there are budget considerations to be made. However, most of the scales on this list can be picked up fairly cheaply, at least compared to other pieces of smart technology.

If you’re just looking for a simple body composition-measuring device that doesn’t cost the earth, you may want to check out the uncomplicated, relatively affordable Eufy Smart Scale C1 or Eufy P2 Pro, as both are very comprehensive and offer you great value for the price.

It’s also worth considering the tech you already own and factoring that into the decision you make. For example, if you’re already heavily invested in the Fitbit economy (i.e. you own one of our best Fitbits and you subscribe to Premium), you may want to pick up one of Fitbit’s Aria-branded scales, which can
upload your data automatically to your Fitbit app. On the other hand, if you already own one of our best Garmin watch picks, the Garmin Index S2 might be the only scale that makes sense for you, as it interfaces in a similar fashion with the Garmin Connect network.

Finally, you obviously want something that looks nice if you're going to be leaving it out to step on every day. Most of the above scales look sleek with their glass platforms, but some can be found in multiple colorways. All are pretty slender, so if you can't find one that fits your vibe, you can always tuck it in a cupboard out of the way when guests are over.

Why get a smart scale?

Measuring your weight can have a positive impact on your weight loss efforts. One study published in the Journal of the Academy of Nutrition and Dietetics found a daily weighing habit improved overall weight loss in overweight participants. Smart scales can take these measurements and automatically upload it to an app, so you can better keep track of your progress. Whether you're trying to build muscle, lose fat or simply stay a healthy weight, smart scales are a powerful tool.

However, for some people, weighing themselves too often can create a challenging relationship with their bodies, especially those who are just beginning a weight management journey. It could potentially lead to unhealthy habits and disordered behavior, so if you see the signs that you're weighing yourself compulsively or too often, don't be afraid to take a break from the scale.

Likewise, if you do have issues around your weight or numbers on a scale are particularly triggering for you, a smart scale may not be the best option to keep you healthy.

How we test smart scales

As you can see in the entries above, we test each smart scale comprehensively. We look at the design of the scale, and that’s not just about looks: we check out whether it’s difficult or easy to set up, how complicated it is to operate, and the design of the companion app if it has one.

We also examine its features, such as what metrics the scale gives you, how many of these are useful, and if the scale requires batteries to be replaced rather than recharged. Finally, we look at its performance, checking its accuracy against its competitors. Check out our how we test page for more.
