Key differences

The most meaningful measured gaps in size and weight — not an overall winner.

  • Height

    Very similar height

  • Width

    Very similar width

  • Thickness

    Very similar thickness

  • Weight

    Very similar weight

Height, width, thickness, and weight are very similar between these devices.

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 S23 Ultra is 0.1 mm (0.1% relative to iPhone 17 Pro Max) wider. Check this difference against the width of your current device and pocket opening.
  • Both have the same listed height (163.4 mm) at the displayed precision. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • Galaxy S23 Ultra is 0.1 mm (1.1% relative to iPhone 17 Pro Max) thicker. Cases and camera protrusions can change the clearance you need.
  • iPhone 17 Pro Max is 1 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.
