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.
- Redmi Watch 4 is 0.1 mm (0.2% relative to Apple Watch Ceramic Series 12 46mm) wider. Check this difference against the width of your current device and pocket opening.
- Redmi Watch 4 is 0.5 mm (1.1% relative to Apple Watch Ceramic Series 12 46mm) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Redmi Watch 4 is 0.7 mm (7.1% relative to Apple Watch Ceramic Series 12 46mm) thicker. Cases and camera protrusions can change the clearance you need.
- Redmi Watch 4 is 19 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.
