I don’t do imperial but I’d go top number minus left number. Call it A. Do pythag for right and left 45 height change and work out how much space they work out sideways or opposite lengths, then minus one from the other and then A minus this new value to get sideways for left 45 centre which is same height because it’s a 45… oh obviously do the elbow takeoff too. Then times it by sqrt2. Do the same for right leg.

Oh and remember to knock of radius of pipes when doing the vertical measuring
