When your measurements sit between two listed ring sizes, the next step is to check how that manufacturer measures the ring and which options the model supports. The electric chastity catalog includes different ring systems and bundles. Compare the actual size chart and package choices before deciding whether you need another size or more information from support.
Confirm which dimension the chart measures
Determine whether a ring number is an internal diameter, an external diameter or a size label. A 45 mm number cannot be compared fairly until both charts use the same definition. Check whether the ring is round or shaped, whether the measurement includes a soft insert, and whether the manufacturer provides a diagram of the measuring points. Do not infer fit from a model photo.
The sizing guide covers how to obtain personal measurements. This article begins after that step, when a result falls between two sizes. It does not prescribe a universal move up or down.
Compare adjacent options within one model
Black Mamba lists ring sizes from 38 to 60 mm. Compare the two adjacent purchasable variations in this same product and their exact selected cage length. A nominal size may reflect one ring system only; another product’s 45 mm ring can have a different profile or attachment. Check the active variation and its stock before ordering, because a family description alone is not the chosen item.
Ask the seller for an internal measurement diagram if your result falls in a gap. Do not assume the larger ring is automatically safer or the smaller one automatically more secure. Shape, material and the specific connection to the cage also matter.
Black Mamba Remote-Controlled E-Stim Chastity Cage
Black Mamba has ring variations extending to 60 mm. Compare adjacent in-stock options within that model, including the selected cage length; do not use its chart for another ring system. See the product details and confirm the selected option before ordering.
Check whether several rings are supplied
The Blue App and Remote Vibrating Cage lists five included rings, 41, 44, 46, 50 and 55 mm, for its stated package. If your measurement sits between two of them, the set may allow a controlled comparison off the body without buying a second ring; confirm the selected package actually includes those sizes. A product that merely offers sizes in a dropdown may instead ship one choice.
Keep the cage, lock and ring from the same model while comparing. A ring with the “right” number from another set may not attach or lock safely. Do not alter a ring to force compatibility.
Blue App and Remote Vibrating Chastity Cage with 10 Modes
The blue dual-control cage lists five included rings. Confirm the exact selected package before relying on that set to compare two nearby sizes. See the product details and confirm the selected option before ordering.
Account for ring shape and attachment
Width and profile affect how a ring sits, and the attachment determines whether it mates with the cage. A round silicone ring can behave differently from a rigid shaped ring at the same nominal diameter. Compare the actual diagrams, material and selected locking connection. A “one finger” rule does not supply a product-specific fit measurement and should not overrule discomfort.
If the chosen size causes pain, swelling, numbness or another concerning reaction, stop using it and seek appropriate professional help if needed. This page is a purchasing comparison, not a medical sizing or diagnostic instruction.
Questions to send before choosing a size
Send one concise request for the exact model and variant.
| Question | Why it matters |
|---|---|
| Internal or external diameter? | Defines the number |
| What shape and cross-section? | Changes the comparison |
| One selected ring or several included? | Changes what arrives |
| Can a different size be ordered? | Do not assume spare availability |
| Which cage attachment fits? | Prevents a mismatch |
Sweetheart’s Promise lists four silicone ring sizes in its package. It is a third configuration to compare, not a reason to transfer its ring dimensions to an electronic cage.
Sweetheart’s Promise Chastity Cage
Sweetheart’s Promise lists four silicone rings in its package. Its material and attachment differ from electronic cages, so the number alone does not establish cross-model fit. See the product details and confirm the selected option before ordering.
Between sizes, the useful next step is a model-specific diagram and package confirmation. No single “size up” or “size down” rule replaces those facts.
