Cuffs are measured by their inside diameter and cuff opening.
Cuff Size Chart
|Size||Inside diameter||Cuff opening|
|Small||52-53 mm (2.05 in)||25 mm (1 in)|
|Medium||56-57 mm (2.2 in)||30 mm (1.2 in)|
|Large||60 – 62 mm (2.4 in)||30 mm (1.2 in)|
Cuffs have two measurements: inside diameter and cuff opening. Both measurements are provided for every cuff in my online shop.
Measure your wrist diameter to determine what inside diameter would fit you (but the cuff size should be slightly larger than your wrist diameter for it to be comfortable).
Measure your wrist thickness – this should be close to the cuff opening size.
