Hey Spod,
To measure girth find a piece of ribbon (this is what works best for me). Ribbon is extremely rigid and when you stretch it as hard as you can the length changes little if any at all. My ribbon is about 1 inch think and around 6.5 inches long. I taped on the ends to make it nice and neat. Then I marked it up using a ruler to go from the 0 inch mark (this point was actually around a half inch from the end of the ribbon to ensure easy measurement) all the way to the 6 inch mark, marking every 1/4 inch.
The standard place to measure girth is at the mid line of your shaft but people measure all over their penis. I wrap the ribbon around the line of my penis while fully erect and then whatever matches up with the 0 mark is my girth.
I would take a picture but my digital camera’s been weird lately.
