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 15 is 1 mm (1.4% relative to Galaxy S24) wider. Check this difference against the width of your current device and pocket opening.
  • iPhone 15 is 0.6 mm (0.4% relative to Galaxy S24) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • iPhone 15 is 0.2 mm (2.6% relative to Galaxy S24) thicker. Cases and camera protrusions can change the clearance you need.
  • Galaxy S24 is 4 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.
