What these size differences mean
Calculated from the dimensions shown, rounded to 0.1 mm and 1 g. Percentages use the smaller measurement as the reference. Fold and rotation settings affect the dimensions compared.

- OnePlus Watch 3 43mm is 0.7 mm (1.6% relative to Galaxy Watch6 Classic 43mm) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
