Key differences

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

  • Weight

    23 g lighter

  • Thickness

  • Height

  • Width

    Very similar width

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.

  • X300 is 0.2 mm (0.3% relative to Galaxy S26) wider. Check this difference against the width of your current device and pocket opening.
  • X300 is 1 mm (0.7% relative to Galaxy S26) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • X300 is 0.8 mm (11.1% relative to Galaxy S26) thicker. Cases and camera protrusions can change the clearance you need.
  • Galaxy S26 is 23 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.
