Tips For Accurately Measuring A Cock Ring, Penis Ring or Glans Ring
Interested in purchasing a fixed sized cock ring? Knowing how to properly measure for size is important and easy to determine.
Finding the right size is important for a comfortable, secure fit. Measuring is quick and easy.
How to Measure for a Fixed-Size Cock Ring
You’ll need: A tailor’s measuring tape, string, ribbon, or shoelace, plus a ruler.
- Wrap the measuring tape or string around the top of the penis and behind the scrotum.
- Keep it snug and comfortable - not tight.
- Mark where the ends overlap.
- Lay the tape or string flat and measure the length. This is your circumference.
- To calculate the approximate diameter, divide the circumference by 3.14.
For the most useful measurement, measure when fully erect. You may also want to take a soft measurement for comparison.
Important:
The calculated diameter is a starting point. The ideal ring size can vary
depending on the ring’s material, thickness, shape, and design. Always check
the sizing information for the specific ring you are purchasing.
Common Fixed-Size Ring Diameters
| Ring Diameter | Approx. Circumference |
|---|---|
| 45 mm (1.77") | 5.56" |
| 50 mm (1.97") | 6.18" |
| 55 mm (2.17") | 6.80" |
A properly sized ring should feel secure without causing pain, numbness, discoloration, or excessive pressure. It should not be difficult to remove.
Measuring for Penis or Glans Rings
Use the same measuring method above.
- For a penis ring, measure around the base of the penis.
- For a glans ring, measure around the head of the penis, just past the corona (the ridge around the glans).
Measure snugly but comfortably without pulling the measuring material tight.
Typical Penis & Glans Ring Sizes
- Glans: 25 mm (1.0")
- Glans: 30 mm (1.2")
- Penis: 35 mm (1.4")
- Penis: 40 mm (1.6")
Sizing Note:
These measurements are general guidelines. Ring fit varies by design and
material, so always refer to the individual product’s sizing information
when available.
