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 is 0.7 mm (1.5% relative to Xiaomi Watch 2 Pro) wider. Check this difference against the width of your current device and pocket opening.
- Both have the same listed height (47.6 mm) at the displayed precision. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Both have the same listed thickness (11.8 mm) at the displayed precision. Cases and camera protrusions can change the clearance you need.
- OnePlus Watch 3 is 5 g lighter. This is the listed device-weight difference, not a measured comfort rating.
Use these figures to compare physical size. They do not establish one-handed reach, pocket fit, durability or an overall winner.
Sources and measurement notes
Sizometry compares published specifications and calculates differences. These are not hands-on measurements or tests of comfort, performance or pocket fit.

Folded and unfolded dimensions differ; cases and camera protrusions may change the space a device needs. Drawings share a relative scale and are not calibrated to life size on your screen.
