Pole Diameter - How to Determine

If you are at the pole

Measure the circumference

Put a tape measure around the pole as if you were measuring your waist for pants size.  Divide the result by 3.14.  Example: The circumference is about 18 7/8".  18.875/3.14=6.01.  So, the pole diameter is 6".  You can convert the fraction to decimal by division.  7 divided by 8 is .875.  If you just want to give us the circumference, we can figure it out. use the "Other" option at the bottom

If you can reach the top of the pole

Measure straight across the top of the pole, and that is the diameter as long as the pole isn't tapered (smaller at the top and bigger at the bottom). 

Eyball it

You can try to eyeball it with a tape measure, but it's sometimes hard to tell whether it's 4" or 4 1/2" that way.
