Open AnyBuild freeHow the framing takeoff is worked out
Framing is a counting exercise, and the counts follow standard practice:
- Plates are three runs of the wall length (two top, one bottom) with 5% for joins.
- Studs are the wall length divided by the centres, plus one, plus two extra per opening for the jambs and trimmers, then multiplied by height with 3% waste.
- Noggins are one row for a standard wall and two rows once the wall is over 2.4 m.
- Lintels are allowed per opening, in LVL, sized to be checked against the span tables.
- Labour is carpenter hours scaled off the wall length with an allowance per opening, plus a base for set-out.
Things worth checking before you order
- Lintel sizes depend on the span and what is loading them. Treat the lintel line as an allowance and confirm the member against AS 1684.2 or IRC R602 for your span.
- Stud spacing interacts with the lining. 600 mm centres can telegraph through thinner plasterboard on long walls.
- Timber is sold in set lengths, so a 2.4 m wall framed from 2.4 m studs wastes nothing, while 2.7 m walls cut from 5.4 m lengths are the efficient buy.
- Add the wraps, braces and tie-downs separately. This takeoff is the framing members, not the bracing schedule.
Common questions
How many studs do I need for a 12 m wall?
At 450 mm centres, about 28 studs plus two per opening; at 600 mm centres, about 21. The calculator adds the plates, noggins and lintels so you can order the whole wall at once.
Is stud spacing 450 or 600 mm?
Both are used in Australia. 450 mm centres is the common domestic default, 600 mm is permitted in many cases and uses less timber. The US equivalents are 16 in and 24 in on centre.
Does it include noggins and lintels?
Yes, noggin rows scale with wall height and a LVL lintel allowance is added per opening.
These figures are indicative and use sample regional trade prices, so treat them as a starting point for a quote rather than a final price. Quantities follow common practice and standard allowances; spans, footings, fixings and compliance for your specific job should be confirmed against the current standards and, where required, an engineer.
