Lumber & framing calculators

5 free calculators · instant · nothing you enter is uploaded

Framing is bought in nominal sizes, sold in board feet and cut to lengths, so the arithmetic is one step removed from what you see on a drawing. These calculators convert between nominal and actual dimensions, price a board by volume, count the joists, studs or deck boards a span needs, and work out stair rise and run from the total height. Each one takes the dimensions you would measure on site and returns the quantity you would write on an order.
