Fit and measuring
Fit is a sequence, not a number a product page can decide for you. Start by measuring, check what each published dimension actually describes, then keep the first fitting easy to reverse.

What these pages do not promise
A measurement can help you compare like with like. It cannot certify comfort, safety, manufacturing tolerance or suitability for a particular person. When a seller does not define a field, we leave it Unknown rather than infer it from a photo or product name.
