I relied on the Amazon reviews that this belt ran small and ordered a size 4 inches larger than my pant size.  The belt has 5 holes about 1 inch apart.  At the tightest hole the belt is larger than my pants.  It looks like 2 inches oversize would allow me to use the middle hole and same size would work.  Measuring from the leather at the buckle, the first hole is at 40 inches and the fifth at 44 inches.  Perhaps there are size inconsistencies but this looks like the belt is close to label size.  A similar Dickies belt in black matches the sizing  exactly.
