How Can I Get The Most Accurate Reading On My Fitbit Scale? - Fitbit Zip Versa Faq

If you feel that your step count and distance are inaccurate, first make sure the wrist placement
settings are correct. Next, double check that you entered your height correctly. Since we use
height to estimate your walking and running stride lengths, you may want to measure and
manually adjust these values if your legs are longer or shorter than average. For more
information, see How do I measure and adjust stride length for my Fitbit device?
Sometimes, when you start walking you may notice that your steps may not update on your
device right away. After about 10-15 continuous steps, you'll notice the steps catch up and start
updating in real-time with each step you take.
To help with the accuracy of your Zip or One device, ensure that you're wearing the clip-based
device in the correct location. For more information on how best to wear any device, see How do
I wear my device?

How can I get the most accurate reading on
my Fitbit scale?
To improve the accuracy of your scale's readings, consider the following tips:

If you pick up and move your scale between measurements, or store it sideways against a
wall when not in use, the scale will calibrate the next time it's used. You may need to
weigh yourself 2 or more consecutive times before the scale calibrates and shows
consistent measurements.

Place your scale on a hard surface during use. Carpet, linoleum, or any other flooring
with resilience may affect the accuracy of the scale's readings.

Your weight and body fat percentage naturally vary over the course of a day and can
change based on what you eat and drink as well as your body stance, age, height, level of
exercise, and perspiration. For consistency, weigh yourself first thing in the morning
before eating, drinking, or exercising. If you're wearing clothes, dress lightly and remove
your shoes and socks.

Your body fat percentage may be affected if you weigh yourself while holding a heavy
object.

If you turn lean mode on or off, your body fat percentage can be affected. For more
information on lean mode, see About Fitbit Aria 2.

For the most accurate BMI and body fat percentage result, your height, age, and gender
must be correct in your Fitbit profile. To update your profile, choose a section below:
