How big around is the Memorial Statue of Sam Houston?

Answer 1

You mean like the waistline?
Scaling from the picture here

with screen calipers
the 67' tall statue is 262 pixels high
the waistline at the vest is 62 pixels wide
which makes the waist 15.85 feet wide.
Using a rough estimate of half as thick as wide and rounding the corners, the waist would measure about 40'
