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 Active is 1.9 mm (5.6% relative to Apple Watch SE 3 40mm) wider. Check this difference against the width of your current device and pocket opening.
- Amazfit Active is 2.4 mm (6% relative to Apple Watch SE 3 40mm) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Amazfit Active is 0.1 mm (0.9% relative to Apple Watch SE 3 40mm) thicker. Cases and camera protrusions can change the clearance you need.
- Amazfit Active is 2 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.
