10 Best Body Fat Scales Tested And Fully Reviewed

3

If you’re serious about losing weight or gaining muscle, an ordinary set of scales may not be enough for you. Standard scales record only your weight; they don’t tell you about your muscle definition, your body fat percentage, or the progress you’re making.

Thankfully there are a number of devices out there which will perform these functions for you, and more. They can even save your data (and that of your family members if they’re also looking to make gains).

So, if you’re looking for a more advanced set of scales, read the list compiled by our expert researchers below.

10 Best Body Fat Scales

 

Weight Gurus

Fitted with leading-edge technology, Weight Gurus' flagship offering is perfect if you're looking for body fat scales. It records your body mass index (BMI), muscle mass and even the weight of the water in your body, so you'll get the detailed informaton you need. Its four sensors offer an accuracy light years away from traditional scales and it can hold up to 400 lbs. The scales sync with Apple Health, Fitbit, MyFitnessPal and more. A portion of the device's sales goes to charity for human trafficking survivors, making it a a healthy, progressive choice in every respect.

Main Features
Along with showing the user’s weight, it gives five additional body results including body fat, lean mass, BMI, water weight, and bone mass, giving an overall look at a user's overall health. What's more it's extremely accurate, giving results to within a variation of 0.2 lbs. Up to eight users can track their weight loss progress on the same device, with each user's results recorded separately. The design is robust as well as stylish, the glass designed to hold even the bulkiest user. The device is non-slip and scratch-resistant, and results are displayed on an ultra-sleek LCD screen.

Technology / Connectivity
Along with storing the results on the scale, the Weight Gurus device also uses Bluetooth Smart / LE technology to send data directly to the accompanying free app for iOS and Android, which can be shared with other fitness apps. The scale runs on four AAA batteries, which are included, and comes with a link to instructions for easy set-up.

What Makes It Stand Out
This body fat scale is similar to the Fitbit Aria, but is around half its price. The smartphone will sync the data remotely; users don't need to have their phone on their person when they're on the scales. As long as the phone is a reasonable distance away, the data will be conveyed seamlessly. Weight Gurus' body fat scale also syncs data separately via 1:1 pairing so it is secure and kept private.

There is a tech support team on hand to assist if and when a problem arises, such as a Bluetooth connection issue, and the product comes with a 5-year guarantee. The company also donates a portion of its proceeds to the Love146 charity to help end child trafficking and give support to survivors, making this the best choice for those looking to help others as well as themselves.
Pros
  • Accurate
  • Easy set up
  • Great price
  • Donation goes to charity
Cons
  • Not for those with a pacemaker or electronic implants
  • Not for pregnant women or children under 10 years old

1byone

This option has the most value for a low price. It measures weight, body fat, water, muscle mass, BMI, BMR, bone mass and visceral fat, and uses Bluetooth to connect to an app to provide data.
Expand to see more
Main Features
This scale measures eight different body composition stats including body and visceral fat. All you need to do is step on its impact-resistant tempered glass and the results are displayed instantly on its 3.3-inch LED screen, as well as its app. It can hold up to 400 lbs, and track the progress of up to 10 users. The device is even set up to record data for babies, so you can weigh your little one without any problems.

Technology / Connectivity
This scale has four high precision bioelectric impedance analysis (BIA) sensors which use an algorithm to detect the user’s stats. Users have to download an accompanying app to sync the data, and the device only supports phones with
a minimum operating system of Android 4.3/IOS 6.1 and Bluetooth 4.0. Power is provided by four AAA devices.

What Sets It Apart
Lightweight and stylish, the Ibyone scales offer a more than adequate level of precision and are extremely priced, with the two-year warranty an additional bonus. The data is also extremely accessible, displayed in easy-to-read line charts, graphs and lists that help the user target where they need to work on.
Pros
  • Affordable
  • Accurate and consistent readings
  • Can store lots of different users' data
  • Has a baby mode
  • Results are highly visual and accessible
Cons
  • Difficulty connecting to app
  • Cannot use with pacemaker
  • Doesn't suit low-end phones

RENPHO

This scale measures 11 body stats including body fat, fat-free body weight, protein and basal metabolism—giving a well-rounded rundown for the user. It alspo has a sleek design with visible sensors showing where to position the feet.
Expand to see more
Main features
The RENPHO product paints a complete picture of the user’s health, using four high-precision sensors, four electrodes and BIA technology to present body composition metrics. The scale is made from 8mm tempered glass and plastic, making it durable enough to hold up to 400 lbs. It has a simple design and the visibility of the sensors is a big advantage.

Technology / Connectivity
This body fat scale uses Bluetooth to sync data to the accompanying app. It also works with other health apps including Apple Health and the Fitbit app to be able to view progress. It comes with 3 AAA batteries, a one-year warranty and customer support. Again, it isn't really suitable for older phones: to sync data from the scales you need a device with at least an Android 4.3 or iOS 7.0 operating system, and it must be compatible with Bluetooth 4.0.

What Makes It Stand Out
Users can weigh themselves with their phones turned off, and the data will sync once the device is back online. There is also no weight limit, so everyone can use these scales.

Yunmai

Yunmai
This smart scale measures 10 different body metrics including body fat, BMI and even hydration and protein levels. Up to 16 users can use the device at the same time (ok, not literally at the same time but you know what we mean) and its accompanying app has a quick and easy set-up. All the key data can be synced with fitness trackers such as the Fitbit and Apple Health, so you can link your weight-loss resuts with your fitness program quickly and easily.
Expand to see more
Main features
The Yunmai scales feature a modern curved design, with bio-impedance sensors integrated into the surface and an LCD porthole that displays stats including body fat, lean body mass, BMR, bone mass, hydration level, muscle, visceral fat, protein levels and body age.

Technology / Connectivity
One of the most user-friendly sets of scales, Yonmai's devices takes just five seconds to setup once the free app is downloaded. Key details flash up on the scales in just two seconds and the measuring system is equipped with a HY3116 24-bit conversion chip to provide higher precision.

What Makes It Stand Out
The sheer range of information provided by the device is probably its greatest single USP. It's also super-fast, easy to use, and it looks cool.
Pros
  • Highly accurate
  • Up to 16 users
  • Loads of data
  • Thin, small and stylish
  • Affordable
Cons
  • Can’t use with pacemaker
  • App can get buggy

 

Nokia Body Cardio

Nokia Body Cardio
Highly accurate thanks to its leading-edge tech, this set of scales offers a full body composition analysis including metrics like weight, BMI, water percentage and standing heart rate. Up to eight users can set up profiles on this slim and stylish option.
Expand to see more
Main Features
The Nokia Body Cardio scales record users' weight, body fat, BMI, muscle, water and bone mass, along with standing heart rate and pulse wave velocity (PWV). The device is ultra-thin, features a solid aluminum base with heat-tempered glass, and is made to work on any surface including carpet.

Technology / Connectivity
The scales are equipped with a patented body position detector technology called Position Control that helps ensure highly accurate readings, along with PWV technology to measure the speed of the user's heartbeat. Results automatically sync via Wi-Fi and to the accompanying free app, giving users an easily accessible overview of their progress. Users can also track their nutrition via MyFitnessPal compatibility, as well as link to their Apple Health account. The device features a rechargeable lithium ion battery that lasts about a year.

What Makes It Stand Out
There is a Baby and Pregnancy mode, and can give weather forecast when using Wi-Fi. It’s stable enough to work on carpet, looks good in either its black or white options

Fitbit Aria

Fitbit Aria
The most recognizable brand in the smart fitness sector, FitBit has become world-famous for its wristbands and the makers have also rolled out a set of scales designed to work directly with them. Up to eight users can set up profiles to measure their weight, BMI, and body fat percentage, and the device is water-resistant, making it great for weighing yourself after a shower or workout.
Expand to see more
Main features
After initial setup this body fat scale automatically recognizes the user and syncs metrics to the Fitbit app dashboard, monitoring a plethora of key indicators including weight, BMI, lean mass, and body fat percentage. Lightweight and with a smooth and glossy finish, it is water-resistant so is designed to stay in the bathroom and withstand humid temperatures without sustaining damage.

Technology / Connectivity
Although there is no Bluetooth support, data is sent wirelessly via the user’s Wi-Fi to to viewed on smartphones and computers. Since it is compatible with the Fitbit app and its family of trackers, users can stay on top of their progress and set goals easily, as well as seeing health and fitness trends in charts and graphs.

What Makes It Stand Out
The FitBit scales include an “athlete mode,” which uses a different algorithm to determine metrics. This is because athletic bodies tend to have more muscle mass and different hydration levels, which effect body fat readings. It’s also the clear choice for those who love and use Fitbit trackers.
Pros
  • Syncs with Fitbit trackers
    Easy to navigate and view stats on platform
Cons
  • Only tracks weights and body fat on scale, rest in app
  • Max weight of 350 lbs

Ozeri

Ozeri
Would you like to have a scale that's merely accurate? Of course not. You want something that's forensic, down to the last gram. This is why we've chosen the Ozeri scale. It has many interesting functions but what really sets it apart is its incredible accuracy.
Expand to see more
Main features
The LCD screen is very easy to read thanks to its high-contrast screen. It can record any user up to a weight of 440 pounds and is just as reliable when recording pets as humans. If you travel a lot, this scale is also great for recording the weight of boxes and parcels.

Technology/ Connectivity
There are 4 buttons which are highly sensitive to touch, and easy to use. The 4 icons, which show up on the screen, provide info about body fat, hydration, muscle and bone measurements. The scale is also equipped with a vast built-in memory bank that can store the measurements of 8 different users, and there's a tracking system to give you regular progress updates.

What makes it stand out
The device's hallmark is its versatility: its capacity to weigh infants, pets and luggage makes it perfect for anyone's needs. The surface is made of special impact-resistant glass that is much stronger than the regular equivalent, and the device is extremely simply to use. If you don’t want to measure all the fancy metrics, you can just take the scale out of the box, step on it and see your weight.
Pros

Very accurate weight measurement

Great tare function

Cons

Some users complained that the scale doesn’t last a particularly long time

Garmin Index Smart

Garmin Index Smart
Ideal for Garmin lovers, this scale tracks metrics like BMI and body composition, syncing directly to the Garmin Connect platform via Wi-Fi to enable you to set goals and view detailed data.
Expand to see more
Main Features
Recognizing up to 16 users, this scale provides weight, BMI, body fat, muscle and bone mass and body water, with more features available when used with Garmin Connect such as goals, calories, activity, and sleep. Lightweight and elegant, it comes in black or white with large numbers displayed on its LCD screen, and it has a max weight of 400 lbs.

Technology / Connectivity
This is a Wi-Fi-connected body fat scale, plus it has both built-in Bluetooth and ANT+ connectivity. It’s the ideal choice for runners and those part of the Garmin Connect fitness community because of its automatic and wireless syncing capability. It has up to 9 months of battery life, although its reliance on AA batteries might be a tiny bit annoying for those used to USB charging.

What Makes It Stand Out
Its connected features makes it easy to set and reach goals using the Garmin Connect platform, perfect for runners who have Garmin watches and trackers.

Etekcity

Etekcity
With 12 different measurements on top of conventional bodyweight, Etekcity offers every type of weight data you could possibly need. Naturally it offers Bluetooth connectivity, so can sync with your phone easily, and it's extremely reasonably priced.
Expand to see more
Main features
With the Etekcity device, you can measure the essentials like weight, body fat and BMI and loads more besides. Muscle mass, bone mass, water weight, even visceral fat... anything you could possibly need is recorded and stored easily. Every user can create their own profile and that helps the whole family to lead a healthy lifestyle.


Technology/ connectivity
A white LED display makes the device truly stand out, literally as well as figuratively. It’s self-illuminated and even when it’s not connected to the phone, the data is stored, ready to sync as soon as your iPhone or Android is back online. The four sensors provide best-of-breed levels of accuracy and their data can be channelled to apps like FitBit and Apple Health, so you can incorporate the analysis into your fitness plan. The stability pads provide real security and many users have praised for the scales for being easy to clean.

Although the device is battery-operated, which may be a turn-off for some, it comes with four AAAs - a nice gift from the manufacturers, we thought.

The one real negative is that the device only goes up to 400lb - so it might not work well for certain people.

What makes it stand out
As well as all the cool features we've mentioned above, the design is a major plus. The glass surface is coated with indium tin oxide, or ITO, which allows the device to detect body composition better (and looks seriously elegant as well).
Pros
  • Tons of different measurements
  • Easy syncing 
  • Works with all the key fitness trackers
  • Ultra-responsive design
  • Keeps storing data even when the phone is off
Cons
  • Battery-operated
  • Has a limit of 400lb

QardioBase 2

QardioBase 2
This gem of a device takes your key measurements including weight, BMI, water weight and bone density and gives them to you via what's called 'haptic feedback' - a series of alerts provided by vibrations and smileys rather than conventional numbers. This system is extremely accessible and easy to use, and the app is also designed to be quick and simple. The scales are charged by USB, not batteries like a lot of other items on our list, and there's even a pregnancy mode for women who are expecting. What's not to like?
Expand to see more
Main Features
Like all the other entrants on our list, the QardioBase 2 records a panoply of features. It may not offer some of the more obscure data recorded by other members of our top 10, but it still provides more than enough for most people. The interface is chic and classy, and you'll have the app up and running in seconds.

Technology / Connectivity
We've talked about the haptic feedback, but it really is cool. You'll love the easy, friendly way the scales send your data, and the information is accurate to within a range of 2 pounds thanks to its group of sensors.

The app is pretty straightforward too, although like a lot of other smart scales, the QardioBase won't suit the most basic phones.

What Makes It Stand Out
Everything about the device is fun and approachable, and we love the Pregnancy Mode, which tracks progress throughout trimesters. The modern disc-shaped design is extremely versatile, blending in to any environment unobtrusively.
Pros
  • Haptic feedback
  • Fun shape and smiley face mode
  • USB-charged
Cons
  • Pricey
  • Not suitable for all phones
  • Initial device set-up can be slightly challenging

 

The Criteria We Used To Find The Best Body Fat Scales

The body scales selected on this list were not chosen based on their brand popularity or whether they are the latest models to hit shelves. Instead, we conducted in-depth research to determine the best options that are on the market. To find the best scales, we made sure they deliver accurate body composition stats, while also being user friendly. Each of the key factors in creating our list of the Best Body Fat Scales is explained below.

Features


Besides providing overall weight and body fat percentage, what other body composition metrics does this scale measure? Customers may also want to see insights into other aspects of their health, drilling down to find out exactly where they’re at with their fitness regime and where they need improvement.  We’ve also examined the accessibility of each device, looking at how easy it is for the average person to use.

Connectivity

Is the device really ‘smart’? To meet this criterion, the Scales must transmit data via Wi-Fi or Bluetooth. It’s also essential that the device comes with an app, and it’s a major bonus if it syncs with third-party apps including Apple or Google Health.

Durability


People come in all shapes and sizes, and body measurement scales need to cope with this. So one of our key criteria was whether the scales could accommodate bigger and bulkier people.

Style


Does the device have an appealing design? Is it stylish enough to leave out in public rooms? Ok, this isn’t as important as some other features on this list, but it’s still a key consideration for many people.

Weight


How heavy and thick are the scales? This might not seem important but, for those people who are always moving their scales from one room to another, it becomes pretty crucial, pretty quickly.

Other Important Factors To Consider

Using a smart set of body fat scales provides users with a panoramic view of their physical health because they can see a full suite of body composition metrics including weight, BMI, and muscle mass. This enables them to take control of their weight loss journey and track their progress because they know what the breakdown is.

Accuracy


It’s important to consider how accurate the data provided by the scales really is. The best body fat scales provide readings which are accurate to within only a few pounds, many of them harness a technology known as bioelectrical impedance, which measures the resistance of electrical waves as they flow through the body to gauge a person’s fat levels. It can be hard to determine belly fat since the waves are measured in the lower half of the body. Other factors like hydration, the time of day, and even a woman’s menstrual cycle can affect the accuracy of the reading.  Because of the use of bioelectrical impedance technology, many body fat scales are not safe for pregnant women or those with pacemakers.

Body Fat vs. BMI


Although many body fat scales also measure body mass index (BMI), these two metrics are not the same. BMI refers to the measure of body fat based on a person’s weight in relation to their height. Body fat percentage is how much fat is in the body. It’s found by dividing the amount of fat mass by body weight.

Since BMI doesn’t take into account the weight of muscle and bone,  body fat is a much better indicator of finding a healthy weight for each individual.

FAQs

Q: How does the scale measure metrics like body fat, BMI, muscle, etc?

A: Many scales use bioelectrical impedance analysis to measure these. A small electrical signal is sent through the legs. The speed of the signal is then able to detect the fat mass, etc. The electrical current moves more quickly through the water, more slowly through fat. This combined with the user’s weight, age, and other metrics, body composition numbers are made.

Q: How does a scale know which user is weighing in?

A: The accompanying apps typically allow the option to add more than one user. Once the new user sets up their own profile by proving info like their age, gender, approximate weight, fitness level, etc., they can step on and start tracking their stats. Using its sensors and algorithms, the app is able to identify the user based on their metrics.

Q: What Is Pulse Wave Velocity (PWV)?

A: PWV is the measure at which waves move along the arteries. Accepted medically, it measures how stiff the arteries are, providing a personal insight into a person’s heart health. The higher the PWV reading, the stiffer the arteries are. High blood pressure, high cholesterol, and diabetes are all factors that can cause stiff arteries.

Q: How do you set up a body fat scale?

A: Setup varies, but generally users download the accompanying app. Set up the profile and step on to start weighing. Many companies also offer an online setup manual on their websites.

Q: How is body age measured?

A: We all have a chronological age, but body age differs by the level of fitness of each individual. Body age is calculated by comparing basal metabolic rate (BMR) and body composition to reveal how old the body is.

Q: When is it best to weigh yourself?

A: It’s best to use the scale at the same time each day. Even though body fat percentiles won’t drop drastically, it’s a good idea to step on every day to track trends over time. Mornings are the best to weigh oneself or wait two hours after eating a meal.
