As my daily driver, the Fitbit Versa 3 monitors my heart rate, sleep, the steps I walk, and the floors I climb every day. However, there’s that occasional struggle with a fit that would be the most optimal for my wrist. To solve this issue for both of us, I experimented to figure out how tight a Fitbit should be and created this article for you.

Let’s dive in!

Quick Navigation

Quick Takeaway
When it comes to tightness, your Fitbit should be tight enough that it should move back and forth in your wrist. Also, it should be loose enough to ensure comfort and not slip from your wrist.

Why Is The Right Fitbit Fit Important?

While Fitbits are amazing health devices to stay updated with your heart rate, step tracking, and more, it is essential to have the right fit.

First, the right fit allows for accurate heart rate and sleep tracking through proper contact with your skin.

Second, it will provide comfort, and minimize the risk of any skin ailments, such as eczema, rashes, or irritation.

Lastly, wearing a Fitbit properly will ensure safety around the wrist area. A tight fit can result in blockage of your blood vessels.

Now, let’s see how tight a Fitbit should be on your wrist.

How Tight Should A Fitbit Be On Your Wrist?

While wearing a Fitbit, you should try to strike a balance between it not being too tight or too loose on your wrist.

Wearing it too tight will cause discomfort and skin problems around the wrist area, whereas wearing it too loose will result in inaccurate readings, and the Fitbit may fall off your wrist.

To ensure an estimated right fit for your Fitbit, try this experiment. After wearing it, put your finger between the band and the wrist. If your finger fits well, it means that you’ve accomplished the right fit!

Also, it should be tight enough that the Fitbit can move back and forth in your wrist, and not too loose that it slides up and down on your wrist.

Now that you know this secret hack, let’s learn the steps to wear a Fitbit.

How To Wear A Fitbit?

Fitbit devices come with sensors that measure heart rate, SpO2 levels in the blood, temperature, and more.

Here’s how you can wear a Fitbit to ensure the right fit:

Note: These instructions are valid for the Fitbit Sense series, Fitbit Charge 5, Fitbit Versa 3 and 4.

  • Place the watch at the top of your wrist.
  • Insert the bottom band in the first loop of the top band.
  • Tighten the strap, ensuring the right fit and comfort for you.
  • Press the peg through one of the holes of the bottom band.
  • Insert the bottom band in the second loop.

Finally, make sure the bottom band rests flat on your wrist, and you’re done.

Tom's love for watches started when his grandfather gifted him his Rolex watch when he turned 18! Being a teenager it was a big deal for him. Later when he got his first job he bought Fossil Palm Pilot back in 2003 which was a smartwatch. Since then smartwatches have come a long way and so is Tom's love for them. His experience with watches inspired him to start Wearholic and share his knowledge of wearables including watches, smartwatches, smart glasses, & smart clothing.
