Evo Measuring Guide

Preface

Before we begin, this guide is primarily geared towards measuring for the Blackout EVO. Our goal here is to get precise and accurate measurements of the various sizes your penis will be.

Here is what is needed:

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

For the flaccid measurements, you will want to measure at the smallest natural size your penis normally is. We want this state just before you would consider your penis to have "shrinkage".

For the erect measurements, measure either with a cock ring or with morning wood. We need this number to be as close to your max so that you are comfortable in even the strongest of erections.

For best results measure over a few days to get a good average

Do not alter these numbers as we do our own calculations to fit the device to you.

1. Flaccid Circumference

Reminder, measure when your penis is as small is it gets in a normal situation (not shrinkage from cold etc.)

  1. Begin by wrapping the receipt/tape measure 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, roughly where a base ring would sit, 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 as the flaccid circumference.

4. Average Testicle Hang

This number is meant to be a description of where your balls sit on average. For most guys this can fluctuate quite a bit but there is a general range. 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 the middle of your range.
