A useful size guide starts with the measurements of the exact product you are considering. PinkChastity will add model-specific charts only after those measurements are verified.
Before you measure
Use a flexible tape measure, note the units, and measure without pulling the tape tight. Compare your notes with the dimensions and measuring points stated on an individual product page; designs do not share one universal fit.
Measurements to compare
Ring size: follow the product’s own guidance for where the ring sits and how its size is specified. Cage length and width: compare your measurements with the product’s verified internal dimensions, where available.
If a product lacks a verified size chart or you are unsure how its measurements are defined, wait for clarification before ordering. Product-specific dimensions will be added as the catalog is prepared.
