Two phones can look similar on a product listing and still need different cases. A useful compatibility claim identifies an exact phone and an exact case version. It should also say whether that match comes from a manufacturer's listing or an actual fit check.
Identify the model first
Use the phone's model information, not a memory of its screen size or the year it was purchased. Apple's identification page is the starting reference for our model archive. Regional variants and a retailer's shorthand can add confusion, so keep the official model name attached to the record.

Dimensions are one part of the picture
A matching height, width and depth does not establish that a case is compatible. Camera geometry, openings, controls, ports and clearances also matter. We keep Apple's nominal dimensions in the archive as reference information; they do not generate an automatic fit recommendation.

Keep the case version
A commercial family name can cover several generations and more than one construction. Record the model variant, SKU, revision or batch when available, plus a photograph of the packaging. A result on one sample should not silently turn into a verdict on every case with the same family name.
Check the interactions
A fit check should look at mounting, removal, retention, port access and the controls on the real device. A display dummy can help show shape, but it does not verify charging or electronic interactions. Camera Control also calls for the intended gestures and pressure interactions to be checked.

Read the evidence label
Our archive starts with public documentation. A manufacturer's compatibility listing remains a manufacturer statement. A future hands-on review will name the phone and case that were actually used, the test date and the limits of that experience. Those two evidence levels will stay visible.
