Key differences
The most meaningful measured gaps in size and weight — not an overall winner.
Height
APEX 4 42mm
0.6 mm taller · minor difference
Width
APEX 4 42mm
0.6 mm wider · minor difference
Thickness
Very similar thickness
Display size
Very similar display size
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.
- APEX 4 42mm is 0.6 mm (1.4% relative to fēnix 7S Pro Solar) wider. Check this difference against the width of your current device and pocket opening.
- APEX 4 42mm is 0.6 mm (1.4% relative to fēnix 7S Pro Solar) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- fēnix 7S Pro Solar is 0.1 mm (0.7% relative to APEX 4 42mm) thicker. 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.
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.
