Housing items question

Is there a way to display sizes..

Like apartment length by width then make the items show it..
Im try to calc how many aquaducks i need to go around the side

Not really - the way I do this is changing the floor to a style that allows to count it out myself. Usually I go for the Palace of the Dead Flooring, which is usually quite cheap and has chessboard-pattern, allowing you to count the squares - bit annoying, but it works... (works also to align things if grid snap doesnt work like you want it to).

There's actually a Preview Furnishings option in housing, so you could go that way
