Will an iPhone 16 Pro case fit an iPhone 17 Pro?
The 17 Pro is taller, wider and half a millimeter thicker than the 16 Pro. Why the cases don’t swap, and how the iPhone 17 and 18 Pro compare.

The short answer
No. Apple lists the 17 Pro at 150 × 71.9 × 8.75 mm and the 16 Pro at 149.6 × 71.5 × 8.25 mm, so the 17 Pro is 0.4 mm taller, 0.4 mm wider and 0.5 mm thicker.
A 16 Pro case is too small for a 17 Pro, and a 17 Pro case is loose on a 16 Pro. Both phones have USB-C, an Action button and Camera Control, but a case cut for one outline puts those openings in the wrong spot on the other.
Side by side
Official dimensions from the manufacturer. Dimensions alone don’t decide fit: camera position, button placement and cut-outs matter just as much.

What actually changes between them
These are the differences a case has to follow. Any one of them is enough to stop a case sitting flat, covering a button or lining up with the camera.
- The iPhone 17 Pro is 0.4 mm taller than the iPhone 16 Pro
- The iPhone 17 Pro is 0.4 mm wider than the iPhone 16 Pro
- The iPhone 17 Pro is 0.5 mm thicker than the iPhone 16 Pro
Is the iPhone 17 the same size as the 16 Pro?
Same height and width (149.6 × 71.5 mm), but the iPhone 17 is 7.95 mm deep against 8.25 mm for the 16 Pro, so their cases aren’t interchangeable either.
| Spec | iPhone 16 Pro | iPhone 17 |
|---|---|---|
| Height | 149.6 mm | 149.6 mm |
| Width | 71.5 mm | 71.5 mm |
| Depth | 8.25 mm | 7.95 mm |
| Screen | 6.3-inch | 6.3-inch |
| Charging port | USB-C | USB-C |
| Side buttons | Action button, Camera Control | Action button, Camera Control |
| MagSafe | Yes | Yes |
And the iPhone 18 Pro?
Apple lists the 18 Pro with the same dimensions as the 17 Pro (150 × 71.9 × 8.75 mm), so a 16 Pro case is just as wrong for it. Whether 17 Pro and 18 Pro cases swap is covered in will an iPhone 17 Pro case fit an iPhone 18 Pro.
Why “almost fits” isn’t good enough
A case that nearly fits can press a side button all the time, leave a gap at one corner where the phone can pop out when dropped, or sit on the camera rim so the lenses touch the table. A raised edge around the camera only protects if it surrounds the lenses exactly.
Every YOONIG case is cut for one model, so the print, the openings and the raised edges line up with that phone. If you are not sure which model you have, our guide to finding your exact model takes a minute.
