Google Fitbit Bands Size Chart India: Small vs Large Wrist Fit Guide

Google Fitbit Bands Size Chart

Google Fitbit Air bands are sized by wrist circumference in millimeters, not by shoe style numbering, so the fit comes down to one measurement: the width of your wrist where the tracker sits. There is some variation between the Active Band, the Performance Loop Band, and the Elevated Modern Band, since each is a different material and clasp. If your wrist measurement falls right between small and large, size up to large for daytime comfort or size down to small for a snug workout fit.

To measure at home, wrap a soft tape measure around your wrist bone, keep it snug without pinching, and read the number in millimeters or inches.

Small	130 to 175 mm	5.1 to 6.9 in	Slimmer wrists, gym and running sessions
Large	165 to 210 mm	6.5 to 8.3 in	Broader wrists, all day wear

Google Fitbit Air Elevated Modern Band

Google's own Fitbit band guidance for the Air lineup follows the same general split the brand has used for years across its wearables: a smaller shell for wrists under roughly 175 mm and a larger shell above that, with a bit of overlap so most people fit comfortably into either size (general pattern via Fitbit official sizing guides).

What Kicks Machine actually has in stock right now

Availability moves fast on these straps, so check before you plan an outfit around one. As of this page going live, the Google Fitbit Air Elevated Modern Band Strap is in stock in Obsidian and Moonstone finishes, on a one size band that covers 130 to 210 mm. The Active Band and the Performance Loop Band are both sold out at the moment (they run on a preorder cycle when restocked), so the full small and large split above is what you will get once they are back, not what you can add to cart today. Your safest bet for an immediate purchase is the Elevated Modern Band, or the full Google Fitbit Air Classic tracker, which ships with its own strap already sized.

Keep an eye on the Google Fitbit Air straps and bands collection for restocks of the small and large options, both come back in rotation.

Frequently Asked Questions

How do I know if I need a small or large Fitbit Air band?

Measure your wrist with a soft tape at the point where you normally wear a watch. Under 175 mm generally means small, above that means large. If you land close to the line, pick large for all day comfort or small for a tighter workout fit, and check the exact range on the [Google Fitbit Air Elevated Modern Band Strap](https://www.kicksmachine.com/products/google-fitbit-air-elevated-modern-band-strap) listing before you order.

Does the Elevated Modern Band fit both small and large wrists?

Yes. Unlike the Active Band, the Elevated Modern Band ships as one adjustable size that covers 130 to 210 mm, so you do not have to choose between small and large when you order it.

Why are the Active Band and Performance Loop Band sold out?

Both currently run on a preorder cycle tied to international sourcing and authentication, which is why they show as sold out between restocks rather than permanently discontinued. Check the [Google Fitbit Air straps and bands collection](https://www.kicksmachine.com/collections/google-fitbit-air-straps-bands-collection) for the next restock window.

Can I use a Fitbit Air band on an older Fitbit model?

No. Google Fitbit Air bands are built for the Air's specific clasp and lug width, so they will not fit older Charge, Versa, or Inspire trackers, even if the wrist measurement matches.

What if my wrist measures right at 175 mm, exactly between small and large?

Go with large if you wear your tracker loose or over long sleeves, and small if you prefer it snug during workouts. A half size band with an extra clasp hole, like the Elevated Modern Band's adjustable fit, removes this decision entirely.

Is a Google Fitbit Air band original if I buy it from Kicks Machine?

Yes. Every Google Fitbit Air band listed on Kicks Machine goes through an in house authentication check before it ships, and orders are cash on delivery eligible, so a sizing mismatch is exactly the kind of thing worth measuring for before you order rather than after.
