Measuring tools
Start with a tool that helps you do one job clearly. It does not collect a body measurement, calculate a supposedly ideal size or recommend a device.

- Chastity cage size and ring measuring guide →
Take ring inside diameter and flaccid cage-length measurements, understand the labels that sellers use, and keep every measurement on your own device.
This is the only tool currently published. We will add another only when it can produce a useful result without inventing a fit formula or collecting sensitive information.
Why it is a guide, not a size calculator
Retailer dimensions do not consistently distinguish inside from outside ring diameter or shell length from usable internal length. A calculator would hide those unresolved definitions behind a precise-looking answer. The measuring guide keeps the definitions visible so you can ask a seller to confirm them.
