DickiesMen's 35mm Genuine Leather Belt

What's the width of tthis belt

How thick is it?

Your product description lists the belt as being 54" in length. if i want a belt that is in fact 54" in length, should i select the size 44 option?

if your waist measures 42 inches......what size belt to order? is the size given the actual length of belt, or the size of waist?
