Another key in measuring the penis is consistency. A guy should take note that there are several factors that affect the penis size such as temperature, recent sexual activity, and time of day. It is important that these factors be taken into consideration whenever a guy decides to measure his penis. The rule of thumb is to follow the same, constant pattern or “setting” in measuring his penis. This means that if his initial measurement was done during the day, all his subsequent measurements should also be done during daytime. This kind of technique ensures that one gets accurate measurement results.

But how exactly is the proper penile measurement carried out? The first thing to remember is that your penis should be fully erect before you measure it. Thus, the first step in measuring your penis is stimulating yourself until you get an erection. Once your member is already in an erectile state, stand so that the entire length of your erect penis is parallel to the floor. With a ruler, measure your penis from its base to its tip. The most preferred way to get this done is by pressing the base end of the ruler or measuring tape until it touches the pubic bone — that bone beneath your skin. When you have already done this, get the closest measurement at your penis’ tip. This measurement your penile length. Don’t attempt to measure your penis while your lying down since this tends to render unreliable results.

For measuring the girth or circumference of your penis, you would need a fabric ruler or a string. While still on the erectile state, wrap the tape measure in the middle of your penile shaft and read the closest inch measurement.

Do not forget to record both measurements (length and girth) to your logbook for future use.
