TOPIC: Updated Penile Girth Calculator

A while back I shared the Rejuvall penis size calculator and it rightfully caught some heat for being way too optimistic in certain scenarios; the numbers were clearly overinflated, especially at higher volumes and on longer shafts.

We’ve gone back and completely re-tuned the calculator based on that feedback and I’d really love for some of you to stress-test it and tell us what you think now.

What’s changed:

• PMMA (Bellafill) math recalibrated using our clinical data tables instead of simple linear assumptions
• HA (Revanesse Versa) adjusted so results better match real-world layering outcomes, especially at higher total mL
• Longer shafts (7–8") now modeled more conservatively so they don’t show unrealistic jumps from modest volumes
• All dropdown options match real syringe sizes (no random mL values we don’t actually use in clinic)
• Visuals and UI are basically the same, but the engine under the hood is new.

If you’ve had HA or PMMA with us (or anywhere else really), we'd greatly appreciate it if you’d plug in:

1. Your starting erect length & girth
2. Filler type
3. Volume you actually received

…and see how close the estimate is to what you got in real life.

You all had thoughtful critiques of the original version, and they were a big part of why we went back and reworked the math. If you’re willing to take another look and try to break this new version, I’d genuinely appreciate any feedback, good, bad, or “still garbage.”

The calculator is meant as an educational / ballpark tool, not an exact promise, but we do want it to be grounded in reality and useful to guys who are early in their research.

Thanks in advance to anyone who takes the time to test it and share notes!

This is great! Thank you!

Still doesn’t work for me. Not sure what the formula is but I can give you my results as an example. When round 2 is complete I will see if this works. I gained 5cc’s of volume for every cc of actual PMMA in round 1. Using the amount injected x the concentration percentage. Bellafill is 20% and I believe it’s 1.2 cc syringes so .24 cc per. If people here would calculate what they received for injections and the result it would be interesting to see the range of outcomes. The length would need to be measured to the glans so that we only use shaft length. To calculate you need to have baseline volume and post procedure volume in cc’s. Find the delta and divide by PMMA material injected to see the gain per cc of material. If everyone is close then we will have a very accurate calculation. If the results are all over the place then it’s not possible to predict.

Thanks for the feedback! Did you come to us for filler, or go somewhere else? Also, how far off were your results with the updated calculator?

For our survey, are you looking for our BPEL or NBPEL?

BPEL please. Sorry, I should have clarified since that's only on the page. Thanks for asking!
