@jasonB - thanks, was what I’m looking for. 

What for a 2 storey house?

And the width of doors and windows?

A two storey house? Well, twice as tall.

Maybe a little less, as upstairs ceilings are sometimes a little lower.

Doors and windows come in a variety of sizes. Just measure up your own and divide by 32. A standard modern door is about 200cm x85cm, so in 1/32 thaat would would be 6.2cm x2.7cm.
