Key differences

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

  • Weight

    Galaxy A55

    6 g lighter · minor difference

  • Height

    1.1 mm taller · minor difference

  • Width

    Very similar width

  • Thickness

    Very similar 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.

  • 17T Pro is 0.1 mm (0.1% relative to Galaxy A55) wider. Check this difference against the width of your current device and pocket opening.
  • 17T Pro is 1.1 mm (0.7% relative to Galaxy A55) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
  • 17T Pro is 0.1 mm (1.2% relative to Galaxy A55) thicker. Cases and camera protrusions can change the clearance you need.
  • Galaxy A55 is 6 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.
