Do the 40mm and 44mm have the same aspect ratio?

They're obviously different sizes, but looking at the two side by side, the 40mm looks slightly narrower in width.
I'm thinking the ratio is slightly different and it's not a simple scale up.

Just curious.

Pixel wise, ratios are almost similar :
40mm : 324 x 394 -> ratio : 1.216049
44mm : 368 x 448 -> ratio : 1.217391

Thanks, but I’m referring to the ratio of the physical casing.

if we do the same math using the case dimensions (height and width) ...

40mm

• Height: 40mm
• Width: 34mm
• Depth: 10.7mm

44mm

• Height: 44mm
• Width: 38mm
• Depth: 10.7mm

40 / 34 = ~1.17647
44 / 38 = ~1.15789

So, yes, the 40 mm is slightly narrower.

It appears Apple rounds off the case sizes to the nearest mm. I carefully measured my actual case sizes (not including the crown) with digital calipers:

44mm aluminum S5:
Height 44.07 mm
Width 37.85 mm
Aspect ratio = 1.164

40mm aluminum S4:
Height 39.90 mm
Width 34.40 mm
Aspect ratio = 1.160

Pretty much the same, within the accuracy of measurement
