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.

  • iPhone 18 Pro Max is 2.2 mm (2.9% relative to 12) wider. Check this difference against the width of your current device and pocket opening.
  • 12 is 0.9 mm (0.6% relative to iPhone 18 Pro Max) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • 12 is 0.4 mm (4.5% relative to iPhone 18 Pro Max) thicker. Cases and camera protrusions can change the clearance you need.
  • 12 is 29 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.

User Experience Summary

12

Strengths

  • 5400mAh battery with 6-10 hours of screen-on time, owners' most-praised feature
  • 80-100W wired charging delivers full charges in roughly 30-55 minutes
  • Hasselblad-tuned camera system genuinely competitive with Pixel and Galaxy

Compromises

  • IP65 rating trails the IP68 standard on Galaxy, Pixel, and most rival flagships
  • Four-year OS update commitment shorter than Samsung and Google's promises
  • Isolated reports of display flickering or green-line artifacts after specific updates
