How to Size Yourself for Chastity

Ensuring you receive the proper size device is key to maximum enjoyment. To help determine what size(s) would be the best fit for you, please follow our short guide below. Please keep in mind, this is a tool to help determine the right size, and a person’s requirements may vary from this guide. We recommend writing down your measurements to ensure the best possible outcome and fitting.
Tip: Use a piece of string to measure circumference.

Step 1

Measure the length of the penis while flaccid (Measure the top of the shaft)

Step 2

Measure the circumference of the penis while flaccid (i.e. girth)

Step 3

Measure the circumference of the entire genitalia (from underneath the ball sack to over the base of the penis – where the ring will sit)

Step 4

Convert the circumference to diameter of both measurements by using this calculator: Omni Calculator

Step 5

Repeat steps 1-4 with an erect penis

Step 6

Take these measurements and compare them with the recommended sizing on the Sizing Options page (also available as a photo on The Vice™ product listing), 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 Support@lockedinlust.com with the subject “Sizing Help”.
