Evo Measuring Guide

Preface

Before we begin, this guide is primarily geared towards measuring for the Blackout EVO. Here is what is needed:

  • An Old Receipt
  • A Pen or Marker
  • Ruler/Tape Measure
  • Your Penis

1. Flaccid Circumference

For the flaccid circumference, measure your penis in a state that is as soft as it usually is. We want the measurements accurate to what you are on average to make it so you are as comfortable as possible as much of the time possible. Do not alter these numbers as we do our own calculations to fit the device to you.

  1. Begin by wrapping the receipt around the base of your shaft
  2. Pull the receipt so it is taut around your shaft, but only with even, light pressure. Make sure the receipt is wrapped around evenly and not at an angle
  3. Mark the receipt on the overlap with your pen and then remove the receipt
  4. Measure the distance between the two marks using your ruler and write it down

2. Flaccid Shaft Length and Total Length

It is important that you don't stretch out your penis at all for the length measurements. We want a relaxed and natural state, much like what you would be in a properly fitted chastity cage.

  1. While still soft, lift up your penis using an open hand underneath. Your penis should be parallel to the ground and not stretched out at all.
  2. Measure from the base to the beginning of your glans(head). Write that number down
  3. Proceed to measure your total flaccid length, which is to the end of your penis. Write the measurement down

3. Hard Circumference

Now get a strong erection and repeat the same process for the flaccid circumference. Feel free to use a cock ring or measure with morning wood to get the measurements for what you will be enduring overnight. However, this time measure around the middle of your shaft to get the largest part of the erection.

4. Testicle Hang

We use a 1-6 scale to generate the perfect base ring for you. A 1 is for testicles that typically sit very close to the body with no hang most of the time. A 6 is for testicles that usually hang well beyond the tip of the penis with lots of extra scrotum skin. Select a value that best describes you on average.
