Learn how to measure for a male chastity cage and choose the right size for comfort and security. Includes fit guidance for the Impound range.
Quick answer
A correctly sized male chastity cage should be snug but not painful—measure your flaccid length and girth, then pick a cage body length slightly shorter than your flaccid length and an inner diameter that allows a finger's width of space.
Why cage length matters more than you think
A cage that's too long lets you start to get erect inside it, which pulls the base ring away from your body and creates painful gaps. A cage that's too short can pinch or cause skin to bulge out. The sweet spot is a body length about 5–10 mm shorter than your flaccid length. That slight compression prevents unwanted growth while staying comfortable.
The Impound Citadel Cock Cage uses a 65 mm body, while the Impound Vanguard measures 87 mm. If you're on the shorter side flaccid, the Citadel's compact profile will likely be a better daily fit. If you're longer, the Vanguard gives you more room without being oversized.
Inner diameter affects circulation and hygiene
The inner diameter controls how snugly the cage holds you. Too tight and you'll have circulation issues or chafing; too loose and you'll slide around, which defeats the purpose. A 35 mm inner diameter works for average girth, but if you're between sizes, err on the larger side—you can always adjust fit with the base ring.
Both the Impound Citadel and Impound Warden use a 35 mm inner diameter and a 65 mm body, making them similar in internal fit despite different designs. The Warden is lighter at roughly 60 g, which some wearers prefer for all-day comfort.
Base ring sizing: the most common mistake
The base ring keeps the cage in place, but it's also the part most people get wrong. A ring that's too tight restricts blood flow; one that's too loose lets the cage slip. The Impound Citadel includes three interchangeable base rings, so you can dial in the fit without buying a separate ring set. That's a practical advantage if you're still figuring out your ideal size.
How to choose your chastity cage size
- Measure your flaccid length: Stand or sit comfortably and measure from the base of your penis (where it meets your body) to the tip. Do this when you're completely flaccid, ideally after a warm shower when you're relaxed. Your cage body should be 5–10 mm shorter than this measurement.
- Measure your girth: Wrap a soft measuring tape around the widest part of your flaccid shaft. Divide that number by π (3.14) to get your approximate inner diameter. For example, a 110 mm girth ÷ 3.14 = roughly 35 mm diameter. Choose a cage with an inner diameter equal to or slightly larger than your calculation.
- Test the base ring fit: Slide one finger between the ring and your skin. If you can't fit a finger, the ring is too tight. If you can fit two fingers easily, it's too loose. The Impound Citadel's three included rings let you try different sizes without buying separate rings. Start with the largest ring and work down until you find the snug but comfortable fit.
Product facts
- Impound Citadel Cock Cage: The Impound Citadel Cock Cage has a shortened 65mm cage body and a snug 35mm inner diameter, with three interchangeable base rings. The short body keeps the profile low under clothing, and the three base rings let you fine-tune the fit without buying extras.
Impound Citadel Cock Cage - Impound Vanguard Cock Cage: The Impound Vanguard Cock Cage uses a heavily vented shell that keeps air moving around the skin, cutting down on sweat and simplifying cleaning. The venting makes a real difference for hygiene during extended wear—you can clean without removing the cage as often.
