An iPhone 18 Pro case will not fit the iPhone 18 Pro Max, and vice versa. The Pro Max is taller and wider, so the two need separate cases even though they share a camera style. Match the case to your exact model.
Quick Take: every case here is molded specifically for the iPhone 18 Pro (correct cameras, buttons, ports). This is a fit + comparison guide. Shop the full iPhone 18 Pro lineup or call/text 978-797-0223 for help.
Note: iPhone 18 Pro specs below reflect current expectations and pre-release reporting, not final specs. Photos show our current-generation case designs while iPhone 18 Pro retail units are in production — final retail photography is pending, but the fit and cutouts are built to the iPhone 18 Pro chassis.
The size gap between Pro and Pro Max
The Pro Max is meaningfully taller and wider than the Pro. A Pro Max case is too big for the Pro, leaving it loose, while a Pro case won't stretch over the Pro Max. Buttons and MagSafe won't line up if you mix them.

Same cameras, different bodies
Both Pro models use Apple's advanced camera plateau, but on differently sized bodies, so the cutout position relative to the edges changes. Only a model-matched case aligns cleanly.

Picking protection for each
Heavy users of either phone do well with the dual-layer shockproof case. The waterproof case seals both models in their own molds, and the metal bumper kickstand case adds a stand. Order from the matching collection.

Don't size up 'to be safe'
A case that's too large lets the phone shift and misaligns the screen lip and MagSafe ring. Always match the exact model.
