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.
- Amazfit Cheetah Square is 0.7 mm (1.8% relative to Apple Watch SE 3 44mm) wider. Check this difference against the width of your current device and pocket opening.
- Both have the same listed height (44 mm) at the displayed precision. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Apple Watch SE 3 44mm is 0.8 mm (8.1% relative to Amazfit Cheetah Square) thicker. Cases and camera protrusions can change the clearance you need.
- Amazfit Cheetah Square is 8 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.
