What is your bottom bracket height? (floor to center)

You can, if you can be bothered, work it out on a frame by measuring how far below the rear drop out the centre of the BB is - then take this figure off half the circumference of a wheel + tyre.

Yeah technically b.b drop is the important number in terms of frame design as it's not effected by tyre size.

Thanks for all the numbers people. Scratched my itch for numbers.
