Framing Calculator Questions

How many studs do I need for a wall?

The standard take-off is the wall length divided by the stud spacing, plus one for the far end. A 20 ft wall at 16 inches on centre works out to about 16 studs before you add openings and waste. The calculator above adds both.

What does 16 inches on centre mean?

It's the distance from the centre of one stud to the centre of the next — not the gap between them. Common spacings are 16″, 19.2″ and 24″ on centre. Drywall sheets are sized to land on those centres, which is why the spacing matters as much to the boarding as it does to the framing.

How much extra framing does a door or window need?

Each opening needs a header, a king stud and a jack stud on both sides, and cripple studs above and below. The calculator allows roughly six extra studs per opening as a planning figure — enter your door and window counts and it works it in.

How much plate material do I need?

Most walls use a single bottom plate and a double top plate, so allow about three times the wall length, plus waste. That's included in the estimate above.

Why does a drywall company have a framing calculator?

Because the framing decides how the board goes on. Stud spacing, crooked studs and a missing backer at a corner all show up later as a wavy wall or a cracked joint. We frame, board, tape and finish, so we'd rather the framing was right the first time.
