Stud wall framing calculator
A stud wall is a repeating module plus the extras at openings and corners.

Show the working
- Wall length = 6
- Wall height = 2.4
- Stud spacing = 0.4
- Openings = 1
- Corners and tees = 2
- Rows of noggins = 1
- Studs from the spacing alone = ceil(6 / 0.4) + 1 = 16
- opening_studs = 1 * 4 = 4
- corner_studs = 2 * 2 = 4
- Studs needed = 16 + 4 + 4 = 24
- Plate timber, sole and double head = 6 * 3 = 18
- Noggin timber = 1 * 6 = 6
- Stud timber = 24 * (2.4 - 0.135) = 54.36
- Total timber = 54.36 + 18 + 6 = 78.36
- Plasterboard sheets for one face = ceil(6 * 2.4 / 2.88) = 5
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- studs = ceil(length / spacing) + 1, plus four per opening and two per corner
Stud length is the wall height less the sole plate and a double head plate, taken here as 135 mm of 45 mm timber.
