Step 1Measure the circumference of the penis while flaccid (i.e. girth)
Step 2Measure the length of the penis while flaccid
Step 3Measure the circumference of the entire genitalia (from underneath the ball sack to over the base of the penis – where the ring will sit)
Step 4Convert the circumference to diameter of both measurements by using this calculator: Omni Calculator
Step 5Repeat steps 1-4 with an erect penis.
Step 6Take these measurements and compare them with the recommended sizing on the product listing (a photo when you click on the product to open it up) in the shop, to see what would be the most ideal fit.
Now you can use these measurements to help determine the best fit for chastity for your anatomy. If you have any questions, please email us at [email protected] with the subject “Sizing Help”.
