Vaginal Opening Width
The diameter of the vaginal canal directly affects how tight the fit is and how comfortable it is to use. With some brands, you can choose this parameter when ordering. There are usually two options available: a standard canal (most often 2cm in diameter) and a wider one (most often 3cm in diameter).
Type 1 — Standard Canal (Usually 2cm)
The standard diameter canal, which factories fit by default. This is what the vast majority of dolls on the market are made with.
Features
- A tight, realistic fit. The diameter is designed around the anatomy of most users.
- The material is elastic, so the canal adapts to size and gives intense sensations.
Who this suits
Most users. If you don't have a specific reason to choose the wider canal, stick with the standard. This is the best option both for sensation and for the material's durability.
Type 2 — Wider Canal (Usually 3cm or more)
An increased diameter canal. This option is designed for users with a larger size, for whom the standard canal physically doesn't suit.
Features
- Comfortable use for a larger size: less resistance on entry and less strain on the material.
- Reduces the risk of damaging the doll. Excessive stretching of the standard canal is a common cause of micro-tears in the material at the entrance.
- The fit will feel noticeably looser for an average size. So it's not worth choosing the wider canal "just in case".
Who this suits
Users with a larger size. If the standard canal feels genuinely tight for you even with plenty of lubricant, and you feel strong resistance from the material, then a larger canal diameter is your option. This matters for the doll too: constant excessive stretching of the standard canal shortens its lifespan.
Users who want less stimulation. If you have issues with ejaculation, or you don't enjoy an intense, tight grip, choose the wider diameter.
How to choose
The rule is simple. If you're unsure, go with the standard canal: the elastic material adapts to size, and the 2cm fit is always tighter. Only choose the wider canal for a genuinely larger size, when the standard is physically uncomfortable or risks tearing the material.
Not every brand offers a choice of diameter. For most factories, the canal diameter is fixed and set by the construction of that particular body. If the brand doesn't offer a choice of diameter, take the body size and material into account when choosing your model. You can find the exact canal depth measurements for a particular body in the body specification section of the doll's product page.
Never use the doll without lubricant, regardless of the diameter you've chosen. Use only water-based lubricant, and in sufficient quantity. This protects both the canal material and its internal texture.
