How to Measure your NBPEL Size?

  • April 28, 2018

NBPEL means Non-bone Pressed Erect Length. Here’s how NBPEL is measured:

  1. Make sure your penis is fully erect. Take a ruler and place it on top, ensuring that the base of the ruler is touching your pelvic skin.
  2. Stretch your penis and adjust accordingly so it is parallel to the ruler.
  3. Take note of the measurement at the very tip of your penis – that is your NBPEL.

NBPEL vs BPEL

When it comes to accurate and consistent measurements, BPEL or Bone Pressed Erect Length is the most recommended procedure.

While NBPEL just measures the visible part of the penis, BPEL encourages measuring the “usable penis” by pushing through the fat pads under the pelvic skin until the ruler touches the bone.

The Average NBPEL

Here is a list of studies for average penis length that used NBPEL as a method of taking a measurement.

  1. Subject: 80 American men – 5”
  2. Subject: 300 men in their late teens to early 20’s – 80”
  3. The Kinsey self-report survey – 1”
  4. Durex online survey – 3”

Note that numbers 1 and 2 are objective medical studies where the measurements were performed by professionals. The figures in numbers 3 and 4 are self-reported data submitted by anonymous men.

Disadvantages of NBPEL

  • NBPEL is considered inaccurate because you are just taking the visible part of your penis.
  • Your fat pads hide some usable length and depending on your weight at a certain time, the thickness of your fat pads will also differ. This results in inconsistency with your measurements.

Measurements Used in Published Studies

Most studies state that the average penis length is between 5” to almost 6”.

There are studies that used NBPEL but they are considered inaccurate and unreliable. The thickness of fat pads vary from person to person, that is why NBPEL is rarely accepted.

Published studies do not usually specify the procedure for measuring the penis of the subjects, but flaccid stretched bone pressed is one of the most common methods used. This is because it may be hard for some subjects to have an erect penis while being examined in the doctor’s office. However, drug-induced erection has been performed in some studies.

The most trustworthy studies performed did not rely on self-reported measurements from the subjects, else they would have been at risk of collecting measurements done through NBPEL.

Nowadays, studies for the average penis length requires the subjects to go to the doctor’s office.
