Tubing is measured Outside Diameter. Pipe is measured by the hole inside diameter = ID. My roll bar is 1 1/2" OD and the clamps for the cross bar are of 2" OD, so with the wall thickness and a rubber strip as a cushion in between it works out. The rubber strips are about 1 1/2" to 2" wide and over 6" long. My roll bar is not shiny or chrome but is was designed to work to protect the driver. taller than my head, thick material with all points anchored to the frame . So many of the roll bars I see are shorter than the driver just sitting sand some are just for looks, some with the rear brace leg just sitting on the rear deck.
