how do you measure girth

[Better Call Saul]

use a measuring tape that you would use to measure your waist and wrap it around until it meets the end of the tape then you've got your girth...

if you haven't got one of those tapes use a piece of paper and same technique but mark where it meets with a pen or pencil then straighten the paper out and use a ruler.

[PetrusRomanus]

Use tape measure and use inch.
