Penicap Dimensions Measurement Chart

Measurements & Sizes

The Penicap chastity cage dimensions are made according the most common sizes of penis of different individuals, due to our long standing experience and knowledge of their variety. Our 7 sizes in 2 mm increment steps cover about 99% of all sizes we have ever met. The correct measurement of the circumference behind the glans is most important for a good functionality and comfort.

How to measure:

chastity cage dimensions - how to choose a size

Measure your penis in a warm condition:  average flaccid and also in erect condition.
Take with a CALIPER distances of the penis shaft in two planes behind the glans at the most narrow diameter and place the caliper without compression. Measure several times, and take an average of all measurements.
If you still have a foreskin , measure with the rolled back foreskin.
A  caliper tool is essential to take correct measurements!

Measure your FLACCID and SMALL penis in warm condition in mm:
Take Diameter 1 and 2

The LARGER of the diameters 1 or 2 = SIZE of PENICAP  (according table below)

if you are between sizes, choose the smaller one.

Examples :
Flaccid penis with largest diameter behind glans: 32 mm = Penicap Size  5
Flaccid penis with largest diameter behind glans: 27 mm = Penicap Size  3

Attention: If your penis has a strong difference between soft and hard state diameter:
more than 5 mm:        1 size larger
more than 8 mm:        2 sizes larger

  • The Penicap does not work properly, if the size was chosen too large:  As a rule the Penicap must be smaller at least 3 mm than the full erect penis.
  • You may choose the Penicap also a bit smaller than recommended. But never smaller than 3 mm less than the recommended size, otherwise discomfort will be likely.
  • If you are in between two sizes, choose the smaller one.
  • Men with a foreskin (foreskin MUST be loose, or problems will arise) must consider the volume of the foreskin, and measure with the foreskin rolled back.
