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 Balance 2 is 0.3 mm (0.6% relative to Galaxy Watch Ultra (2025)) wider. Check this difference against the width of your current device and pocket opening.
- Both have the same listed height (47.4 mm) at the displayed precision. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Amazfit Balance 2 is 0.2 mm (1.7% relative to Galaxy Watch Ultra (2025)) thicker. Cases and camera protrusions can change the clearance you need.
- Amazfit Balance 2 is 18 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.
