The 10 Best Body Fat Monitors of 2022

Verywell Fit / Chloe Jeong

Body fat monitors are tools that can provide data to support a healthy lifestyle. Monitors can be scales, handheld devices, or calipers that calculate your percentage of body fat versus lean body mass and can help track change or progression over time. Most body fat monitors measure body composition through bioelectrical impedance or skinfold measurements.

Reviewed & Approved

The Withings Body+ Body Composition Wi-Fi Scale is our top pick for it's ability to store multiple user profiles, and it's auto-recognition feature. The EatSmart Digital Body Fat Scale is another option with auto-recognition at a lower price point.

“When choosing a body fat monitor, it’s important that you choose one that fits your lifestyle,” says Kim Mahony, RD, LDN, corporate manager of nutritional services at Lutheran Life Communities. Scales are good for home and don't require any training to use while calipers are portable but may require assistance from a friend or trainer to use properly. Mahony notes that while all body fat monitors have some accuracy limitations, measuring using the same method every time gives you helpful info.

When shopping for a body fat monitor, consider if you need to be able to toss it in your gym bag or if it can sit in your bathroom at home. If multiple people will be using it, you may need a style that stores multiple profiles or links to an app. We evaluated our picks based on what style they are, the types of measurements they take, and data memory and other smart features.

Body Mass Index (BMI) is a dated, biased measure that doesn’t account for several factors, such as body composition, ethnicity, race, gender, and age.

Despite being a flawed measure, BMI is widely used today in the medical community because it is an inexpensive and quick method for analyzing potential health status and outcomes.

Here, the best body fat monitors on the market.

This body fat monitoring scale is our top overall choice and an excellent option for the tech-savvy user who is looking for both goal-setting assistance and a sense of accountability. It uses bioelectric impedance to analyze your full body composition, stores data for up to eight people, and automatically recognizes those people when they step on the scale. It syncs with the Health Mate app, which tracks all wellness data points over time so you don’t have to record anything manually.

Connecting to the app and setting up the scale is simple and easy, and the app hosts a slew of special features for anyone interested in really digging into the many aspects of their health.

What Our Testers Say

“The scale’s ability to connect to your phone takes it a step above the scales of yesteryear. After the initial setup, the scale automatically sends all measurements to your phone within a few minutes of weigh-in. The ability to track your fitness progress without any manual charts or extra work allows you to focus completely on getting the results you’re after.” Wendy Bumgardner, Verywell writer and product tester 

EatSmart Digital Body Fat Scale with Auto Recognition Technology

  • Precise measurements

  • Displays English and metric units

  • 400-pound weight capacity

  • Doesn't store data points

  • Doesn't measure BMI

This scale uses bioelectric impedance to estimate your body fat percentage, muscle mass, bone mass, and total body water, in addition to measuring body weight in 0.2-pound and 0.1-kilogram increments. It can support up to eight user profiles, but it does not store any scale data for those users.

After you set up your profile with the scale—providing your height, age, gender, activity level, and an initial weigh-in—it automatically recognizes you when you step on in the future.

For ideal results, stand on the scale in bare, dry feet whenever you want a new reading. And remember that people with pacemakers should not use bioelectrical impedance body fat monitors due to the (otherwise harmless) electric current they require to take a measurement.

Key Specifications

Style: Scale | Data memory: Up to eight users, but no data points | Smart features: User autorecognition

What Our Testers Say

“Besides telling you your weight in units of 0.2 pounds or 0.1 kilograms, this scale also uses a small electric current to measure body fat, water, muscle, and bone mass.  Up to eight users can store their profiles on the scale and the scale will automatically recognize which person is using it. The scale performed well, but I found myself missing having it display a body mass index.” Wendy Bumgardner, Verywell writer and product tester

Qiorange Digital Display LCD Body Fat Caliper Skin Fold Analyzer

Qiorange Digital Display LCD Body Fat Caliper Skin Fold Analyzer
  • Best for measuring body fat around the stomach

  • Easy to read and understand

  • Slightly uncomfortable

Want to combine the skinfold assessment method with an easy-to-read digital display? Check out these Qiorange calipers. They are primarily designed to provide a body fat percentage reading by measuring subcutaneous fat specifically around the stomach, but you can still physically measure the other areas of your body typically included in comprehensive skinfold assessments.

For ultimate accuracy, some users recommend measuring the same area with the same technique three times and taking an average of the reported results. These make skinfold assessments more accessible to folks who don’t have a person available to help them use traditional calipers. In addition, the LED display is large enough for easy reading.

What to Look for in a Body Fat Monitor


There are three main styles of body fat monitors on the market today—scales, handheld devices, and skinfold calipers. Each style is used differently (and provides varying levels of accuracy) to give you a snapshot of your current body fat percentage, so consider which works best for your lifestyle, preferences, and goals before making a purchase. Scales are home-friendly, handheld devices are ideal for your gym bag, and calipers generally don't require an app or batteries to use.


Handheld monitors and scales often use bioelectrical impedance analysis (BIA) to measure body composition by sending weak electric currents through the body. While these devices make measuring body fat at home easier and more affordable, Lauren Hubert, MS, RD, says they come with limitations. 

“Not only is BIA impacted by your hydration, but it also tends to overestimate body fatness in lean and athletic individuals and underestimate body fat in obese individuals,” she says. Because of this, Hubert says it’s best to use these devices as a tool to monitor change over time. 

Skinfold calipers require self-measurements instead of automatic measurements. Hubert warns that they can be difficult to use if you’re not clinically trained to use them, so your measurements can come with inaccuracies.

Data Memory

Most digital body fat measurement devices can store a certain amount of data entries and organize them per user, but this capacity varies dramatically from tool to tool. Such data memory helps users analyze potential trends in body fat percentage changes, further supporting new wellness and lifestyle goals. But if you plan on sharing the device with another person, be sure it offers memory storage for at least two users to keep all data organized and separate.

Smart Features

“If a scale or body composition machine comes with smart features like Bluetooth connection, I think that is a fantastic tool to track your readings,” says Hubert. Luckily, most modern body fat monitors on the market today have the ability to sync with your phone via either Bluetooth or WiFi, making it easier to keep track of your health goals no matter where you are. 

If you’re really into data, review the specific technical capabilities of a body fat monitor you’re considering before you buy it. “Having the ability to track your readings as months go by is an amazing way to keep track of your progress and statistics,” notes Hubert. However, she advises against recording your body composition daily since the smart features are designed to track changes over longer periods of time.

Frequently Asked Questions

  • What is the optimal body fat percentage for my age?

    While all bodies are different and body fat percentage may vary depending on several factors, a study published in the American Journal of Clinical Nutrition determined optimal body fat percentage ranges at a given age.

    Age 20-39: 21%-32%
    Age 40-59: 23%-33%
    Age 60-79: 24%-35%

    Age 20-39: 8%-19%
    Age 40-59: 11%-21%
    Age 60-79: 13%-24%

  • What does a body fat measurement tell you?

    Body fat measurement can tell what percentage of your body weight is made up of fat relative to other lean tissues such as bone, muscle, water, and organs. Body fat percentage is a clearer measurement of your health and fitness than weight or BMI.

  • What measures should I consider in addition to body fat for optimal health?

    While body fat percentage can give you insight into your health and fitness, there are several other factors to consider to measure your health. Vitals such as heart rate, blood pressure, and blood sugar are good measurements of your overall health. Additionally, you'll want to look at your nutrition and physical activity. Sleep habits can certainly play a role in overall health and fitness as well.
