Internal Length

Ready for a fun and sexy guide to getting the perfect measurement for your custom-fit penis extender? Let’s make sure it’s accurate for the best fit and comfort:

First things first, get fully erect to measure your maximum length to ensure the perfect extender internal size – right from base to tip, this is your internal length!

Internal Diameter

Let’s dive into the details of diameter and girth—essential for ensuring a perfect fit for your new extender:

• For Diameter: Measure the thickness. When you’re fully erect, grab a ruler and measure straight across the widest part of your shaft. That’s your diameter. Easy, right?
• For Girth: Take a measuring tape and gently wrap it around the thickest part of your shaft. Not too tight, not too loose. This is your girth.

Try to be as accurate as possible here, so ensure your new Penis Extender fits as well as possible!
