Amazfit strap size chart: 20mm or 22mm by model

Amazfit straps come in 20mm and 22mm. Active 2, Active, every GTS and the GTR Mini take 20mm. Balance, Bip 5, Bip 6, GTR 3 and GTR 4 take 22mm. Bip 3 and Bip U are on the 20mm list too, so a Bip strap doesn't always fit another Bip.

From Amazfit's strap size guide, read November 2026. Balance 2 appears only on the copy of the list in Amazfit's FAQ. Amazfit states the attachment only for the Active 2, and newer models aren't in the guide yet, so we don't list them. Amazon links are searches, so check that the listing names your watch.
