A good fitting cock ring results in a longer and stronger erection, but only when there is the right amount of constriction. Stretchy or adjustable cock rings will fit most guys, however for some silicone and metal cock rings it’s best to buy a size fitted for you.

Use our 4 step plan below on how to measure yourself for a cock ring.

4 EASY STEPS TO MEASURE

how to measure for a cock ring

2. Get Fully Erect

In order to get the right fit, it is important to measure yourself when you are fully erect. You want the cock ring to be a little snug so it will keep your penis plumb while it is at its hardest.

3. Wrap It Around

Now that you are fully erect, wrap the tape measure or the piece of string tightly around your shaft. Hold your finger at the part where the tape or string meets itself. Measure and note the length.

You can either measure your shaft where it meets the rest of your body (behind your balls), or before your balls, depending on where you want to wear a cock ring.
