💡 Between two sizes?Choose the smaller size for a snugger fit — ideal during sport or activity.
Choose the larger size for a looser fit — great for everyday wear.
Either size works perfectly — it's purely personal preference. Outside our sizes? We can also make a custom size for you.
⚠️ Please note: After selecting your wrist size, please also check that your Fitbit model is compatible with our straps. You'll find the full compatibility list in step 2.
How to measure your wrist
Measure your wrist where you'd normally wear your watch.
1
Using a tape measure
Wrap the tape measure around your wrist, just above the wrist bone. Not too tight, not too loose — one finger should fit between the tape and your skin.
2
No tape measure?
Wrap a charging cable or strip of paper around your wrist and mark where it meets. Lay it flat and measure with a ruler.
2Step 2 — Check your model compatibility
Is your Fitbit compatible?
Look up your exact Fitbit model to check whether it's compatible with our straps.
Please note: Not all Fitbit models are compatible with our straps. Some models use a different strap attachment and will not fit.
