Key differences

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

  • Thickness

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 M55 is 0.4 mm (0.5% relative to X9d) wider. Check this difference against the width of your current device and pocket opening.
  • Galaxy M55 is 2 mm (1.2% relative to X9d) taller. 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.
  • Galaxy M55 is 13 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.
