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.
- A3 Pro is 0.1 mm (0.1% relative to Note 12) wider. Check this difference against the width of your current device and pocket opening.
- A3 Pro is 0.1 mm (0.1% relative to Note 12) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Note 12 is 0.1 mm (1.3% relative to A3 Pro) thicker. Cases and camera protrusions can change the clearance you need.
- Note 12 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.
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.
