However, choosing a Fitbit isn’t always easy, especially when choosing one for kids! That is why we have put together this helpful guide on picking out the best Fitbit for kids in 2022, and we’ll also show you which one is really best suited for your child’s age group! So you do not have any regrets later down the line!

Why is it essential to pick the right Fitbit for your Kids?

Age is a vital factor because the Fitbit devices are designed to track different age-appropriate activities. For example, a younger child’s Fitbit such as the Ace 3 and Ace 2 are limited to tracking steps and sleep stages, while an older child’s device might include features such as calorie intake, blood oxygen, heart rate monitoring, and many more.

What is Parental Control in Fitbit?

Parental control and user-friendliness are other factors you should consider while purchasing a fitness tracker or smartwatch for your kids.

Fitbit has an advanced parental control feature that allows you to set up profiles for your kids via Fitbit App. You can also view, create or delete these profiles on your Fitbit device. This means you can limit what they can do on the Fitbit itself, a great feature that helps protect your child’s privacy!

How to find the Right Fitbit for your Kids?

Choosing a fitness tracker with the right fit on the wrist is crucial to accurately track health and fitness metrics. Generally, the Fitbit devices are available in three different sizes: small, large, and X-Large.

Since Fitbit has a tool to determine the correct wrist size, selecting the right one for kids might be easier than expected! Just take a printout of this tool and measure your child’s wrist. To help you choose the appropriate size of Fitbit, I’ve included a link to the Fitbit Size chart for each fitness tracker below.

Fitbit Buying Guide for Kids

Best Fitbit for Kid

Not sure about the factors to consider while buying a Fitbit for kids? Here is a quick guide that will help you make the right decision:

Age of Child

When it comes to buying an activity tracker for kids, your child’s age should be one of the key factors you consider. There are fitness trackers available for children as young as four years old, while others are suitable for older children. That is why I have categorized each Fitbit for different age groups in this guide.

Wrist Size for Kids

The size of your child’s wrist is something you will have to consider while buying a fitness tracker. Fitbits are available in multiple sizes, so ensure that the device fits nicely on your kid’s hand perfectly without coming off or being too tight on their hands. Remember, it should be comfortable enough for your child to wear it all day long. The Fitbit size tool will help you find the right size of Fitbit for your child.

GPS vs. No-GPS:

If your kid is an athlete or runner who also loves to explore new places, you might want to consider getting an activity tracker with GPS, and this will help you keep track of their location and movements even when they are not at home.

Note: Please be noted that your kid must have a smartphone to track the location.

However, if your child is not into outdoor activities and does not need GPS tracking, there are plenty of other Fitbits available that do not have this feature.


Getting a Fitbit tracker for your water-resistant kid can be really beneficial. Fortunately, all the Fitbit wearables mentioned here come with 5 ATM water resistance, which means that it is suitable for swimming up to a depth of 50 meters.


The display size and quality should be one of the key factors you consider while buying a Fitbit for your child. Most Fitbits in this guide come with OLED displays that are easy to read and give clear feedback on all types of activities, including sleep patterns, running, etc.

Security Features

Security is very important when it comes to buying a Fitbit for your child. Since these trackers come with GPS and other features, you will want to ensure that these device does not fall into the wrong hands or be used by another person without permission.

Child-specific Fitbit such as the Ace 3 and Ace 2 can be secured with a Fitbit Family account or parental control. This allows parents to watch their child’s activity, location, and more.

Battery Life

All Fitbit Smartwatches and activity trackers are known for their long battery life. Even the most advanced Fitbit Sense offers five days of battery life, and Ace 3 or Inspire 2 would be a better choice as both wearables offer more than 7-day battery life.

Final Words

Now you have a carefully picked list of the best Fitbit for kids above the age of 6 and have a couple of good activity trackers for younger ones under the age of 6.

So, which one do you like?

The Luxe or Charge 5 would be a better option for older kids. If you are looking for the best fitness tracker for tweens, go for the Fitbit Sense or Versa 3.

I hope that now you have decided which Fitbit is best for your little one. Just take a printout of the Fitbit wrist size tool added to each Fitbit mentioned above to confirm the size.
