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.
Measure the circumference of the penis while flaccid (i.e. girth)
Measure the length of the penis while flaccid
Measure the circumference of the entire genitalia (from underneath the ball sack to over the base of the penis – where the ring will sit)
Convert the circumference to diameter of both measurements by using this calculator: Omni Calculator
Repeat steps 1-4 with an erect penis.
Take 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 Support@lockedinlust.com with the subject “Sizing Help”.
