How to Measure for a Chastity Cage
Start with the size chart for the exact model you are considering. Cage length, cage diameter and base-ring size describe different parts of a device. A label such as Small, Nano or Standard applies to that model; it is not a universal measurement shared by every cage.
Keep a note of each measurement and its unit, then compare it with the available configuration. If you are comparing a device you already own, measure the same parts and use the same start and end points shown in the new model’s diagram.
Base Ring Size
Check whether the listed ring measurement refers to the inner diameter, an adjustable setting or another dimension. Diameter is the distance across the inside of a circular ring; circumference is the distance around it. Do not compare one directly with the other.
Ring shape also matters when interpreting a size chart. A round ring and a shaped or hinged ring with the same nominal size may have different dimensions. Confirm the ring type and the selected option on the product page. Some listings include one chosen ring, while others describe a set; use the package information for that specific configuration.
Cage Length
Read the diagram to identify where the length measurement starts and ends. Some products state that a measurement excludes the base ring. Others list a cage dimension without explaining whether it is an internal or external measurement. Do not add, subtract or assume a standard allowance when the listing does not define it.
Compare numbers only when they refer to the same dimension. If the diagram and written specification are unclear or disagree, ask for clarification before selecting a size.
Cage Diameter
Keep cage diameter separate from base-ring diameter. Where a listing specifies an inner diameter, compare that internal measurement with the equivalent dimension on another model. The outside width of a cage or the width shown in a product photograph is not a substitute.
Use the units printed on the chart. For unit conversion, 1 inch equals 25.4 mm; rounded inch and millimetre values may differ slightly. Do not estimate a missing dimension from the apparent scale of a photograph.
Understanding Different Cage Styles
Small chastity cages group compact size options, while flat chastity cages focus on a low-profile shape. A flat design is not automatically the smallest option, and a small cage may still project outward.
Inverted designs have a different structure from conventional projecting cages. Check the diagram and any separately listed component dimensions; an inversion or component length is not interchangeable with cage length.
Material categories such as metal, resin and silicone do not establish a shared sizing system. For electric models, also check whether the selected configuration changes the components or dimensions.
Check the Product-Specific Size Chart
- Confirm the model, cage style and selected size.
- Record cage length, cage diameter and base-ring size separately.
- Read any labels that specify internal dimensions or exclude the ring.
- Match the selected configuration to its image, measurements and package list.
- Ask about missing or conflicting information instead of assuming that another model’s chart applies.
No single size is suitable for everyone, and a size label alone does not guarantee fit. For help interpreting a listing, contact us with the product link and the specific measurement you need. You can then return to the chastity cage collection to compare your options.
