** How to use the penis size visualizer: The visualizer is intended to demonstrate the difference in size that can be obtained by increasing girth or length. Enter your current girth and length in inches and then use the slider to see what an increase of a certain amount of girth would actually look like. The app is programmed to add 0.5 inches in length onto a 0.5 inch increase in girth and to add a 0.75 inch increase in length to anything above 1 inch in girth increase. This is approximately what we see in real life which is why we have programmed this into the visualizer. Note: Length gains are flaccid. Girth gains are flaccid and erect.

Understanding Average Sizes Used in the Calculator

Most men wonder how their penis size compares to the average. Generally, the average erect penis is about 5.1 inches in length and 4.6 inches in girth. Average however, does not equal "normal." There are standard distributions from average that dictate the measurements that 66%, 90%, 95% and 99% will have as well. "Normal" can likely be considered anywhere within the 99th percentile meaning 1 out of 100 would be out of that range.

What is the Upsize Penis Filler Procedure?

The Upsize Procedure is a non-surgical, minimally invasive penis enlargement technique that uses hyaluronic acid fillers to increase penis girth and, to a lesser extent, length. The procedure is performed by medical specialists, ensuring the highest standard of care. Our doctors are all medical specialists with advanced training in their fields, providing you with the expertise required for safe and effective penile enhancement results.
