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.

  • Robot Phone is 0.1 mm (0.1% relative to Galaxy Z Fold8 Ultra) wider. Check this difference against the width of your current device and pocket opening.
  • Galaxy Z Fold8 Ultra is 7 mm (4.6% relative to Robot Phone) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • Robot Phone is 0.7 mm (7.9% relative to Galaxy Z Fold8 Ultra) thicker. Cases and camera protrusions can change the clearance you need.
  • Galaxy Z Fold8 Ultra is 33 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.

Sources and measurement notes

Sizometry compares published specifications and calculates differences. These are not hands-on measurements or tests of comfort, performance or pocket fit.

Check the exact model, year, region and configuration on the linked page. References may cover several variants. Folded and unfolded dimensions differ; cases and camera protrusions may change the space a device needs. Drawings share a relative scale and are not calibrated to life size on your screen.
