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.

A three-step fit path

  1. Measure ring diameter and cage length

    A private, input-free chastity cage size guide for taking the two measurements and spotting ambiguous retailer labels.

  2. Read size claims before comparing them

    Learn why ring diameter, shell length and usable internal length are not interchangeable fields.

  3. Plan a reversible first fitting

    Follow the assembly sequence, test the release first, and know where generic instructions stop.

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.
