Virtually everyone has a standard scale at home. So it's all too easy to lean on how much you weigh as proof that you're on track (or not) with your fitness goals. But the number of pounds flashing on an old-school bathroom scale can't tell us how much of our body is fat as opposed to lean mass. That's where body fat scales come in.

"Body fat scales are tools to measure aspects of your body composition," explains Marvin Singh, MD, precision medicine expert from the Precisione Clinic in greater San Diego. "They commonly use a method called bioelectrical impedance analysis, which basically sends a weak current through your body to determine your body composition."

What to Look for in a Body Fat Scale

As you can see, body fat scales sport an array of features. Many of those boil down to personal preference, says Dr. Singh. "What kind of power source they use, how big it is, whether it has Wi-Fi or Bluetooth capability or not...consider what features really matter to you before making your choice."

Generally speaking, though, Anel Pla, certified personal trainer at Simplexity Fitness in New York City, points to these as key features:

1. Precision Sensors

The most important feature your digital body fat scale must possess is the ability to provide accurate results. This will rely heavily on the sensors.

2. Different Measurement and Date Options

Aside from body fat percentage, some body fat scales can also compute visceral fat (fat that hides in the spaces between the abdominal organs, which can create serious health issues), BMI, bone and muscle mass, water weight and metabolic age, among other measurements.

It's also nice if it enables you to track different goals on a daily, weekly and monthly basis.

3. Usable on Carpet (if You Don't Have Any Hard, Flat Floors)

Many scales don't generally measure effectively when placed on carpet or uneven tile.

4. Simple Instructions

They should be easy to understand, with useful diagrams and advice on how to interpret your results.

5. Ample Profiles

There should be enough profiles (saved sets of individual information) for all household members who will regularly use the scale. A "guest" profile can be handy for visitors.

6. Tempered Glass

It stands up best to humidity, which is important if the scale will be left in a bathroom.

Tips for Using a Body Fat Scale

"Body fat scales provide rough estimates, since the results are influenced by external factors and variables that our bodies go through," notes Pla. "Nevertheless, they still come in handy in tracking your fat loss progress."

Here, she offers a checklist to ensure results are as precise and useful as possible.

  • Make sure your feet are bare and clean to ensure good contact with the scale's sensor pads.
  • Measure yourself at the same time of day on the same surface (a hard, level floor, unless your scale is specifically made for accuracy on carpeting.)
  • Don't eat or drink for four hours beforehand.
  • Try to urinate within 30 minutes previous to taking a reading.
  • Don't use your scale immediately after waking up, or for 24 hours after excessive exercise or alcohol intake. Your body's water content could be uneven or atypical, which will make the reading unreliable.
