Hi - I've not measured it personally but according to the Swazi site the waist is 45" on these. There is some scope (either way) with this due to the material and the stretchy waistband. The inside leg length is about 31" - again, there is a large tolerance due to material and the cuffs. Incidentally, I'm not sure where the belt is. I will try to find it, but if I can't virtually anything else would be fine. It was just a nylon thing with a snap fastening, sure it's around somewhere.
