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.

This comparison includes preview estimates. Differences may change when final specifications are available.

  • Both have the same listed width (71.6 mm) at the displayed precision. Check this difference against the width of your current device and pocket opening.
  • Both have the same listed height (147.6 mm) at the displayed precision. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • Both have the same listed thickness (7.8 mm) at the displayed precision. Cases and camera protrusions can change the clearance you need.
  • A direct weight difference is not shown because comparable fixed device weights are unavailable or include a strap.

Use these figures to compare physical size. They do not establish one-handed reach, pocket fit, durability or an overall winner.
