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.
- Galaxy M55 is 0.5 mm (0.7% relative to F4) wider. Check this difference against the width of your current device and pocket opening.
- Galaxy M55 is 0.7 mm (0.4% relative to F4) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Galaxy M55 is 0.1 mm (1.3% relative to F4) thicker. Cases and camera protrusions can change the clearance you need.
- Galaxy M55 is 15 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.
Galaxy M55
No source link is recorded for this model yet. Treat its listed figures as unverified.
Check the exact model, year, region and configuration on the linked page. References may cover several variants. 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.
