Will This Cage Fit You?

Yes — you need three body measurements: flaccid length, flaccid circumference, and base ring circumference. If you've already used our Size Calculator, these pre-fill automatically. Not sure how to measure? Our sizing guide walks you through it step by step.

Some product pages list specs as images rather than text. If dimensions can't be extracted automatically, you'll see a manual entry form where you can type the cage length, diameter, and ring sizes yourself. Most users get a full result either way.

Accuracy depends on the quality of product data and how precisely you've measured. When all three key dimensions are available and your measurements are accurate, the analysis is highly reliable. The confidence indicator (high/medium/low) tells you how complete the product data was.

Cage Check works with any online store that has a public product page — including Amazon, Etsy, Lock The Cock, Chastity Cages Co, AliExpress, and independent shops. If the page lists dimensions in text, the tool will find them.

80–100 is a great fit. 60–79 is a good fit with minor tradeoffs. 30–59 indicates significant mismatches worth reconsidering. Below 30 means there wasn't enough data to determine fit — try entering dimensions manually.

Each dimension (cage length, cage diameter, ring size) gets its own rating: perfect, acceptable, tight, loose, or unknown. This shows you exactly which aspect of the cage may not work for your measurements.

High confidence means all three key dimensions were found. Medium means two out of three. Low means one or none — in which case, enter dimensions manually for a better result.

Your measurements are stored only in your browser's local storage for convenience. Product URLs are cached briefly to speed up repeat checks. We never share personal data with third parties.

Chastity cage sizing is genuinely difficult. Product pages list dimensions in different units, use inconsistent terminology, and rarely explain what the numbers mean for fit. Most buyers waste $100+ on cages that are too long, too tight, or have the wrong ring diameter. Cage Check exists to eliminate that guesswork.
