Calculators/Wall framing

Wall framing takeoff calculator

Studs, plates and sheathing for a straight wall — and a clear statement of what is deliberately left out, so you know what still has to be added.

Check the result against the job. This does the arithmetic from the values you enter. Building codes, span tables and material specifications vary by jurisdiction and by product, and the governing document is your approved drawings and your local code. Nothing you type here leaves your browser: the calculation runs on your device and we never receive it.

How this is checked. Every formula on this site runs from one shared calculation engine, and every one has a test fixture whose expected answer was worked out from the geometry or taken from a figure the trade already publishes — never from what the code returns. Some land exactly, which is the point: a 6/12 hip over a 144″ run is exactly 216″, a 45° crown in a square corner bevels at exactly 30°, and a 30° conduit bend has a multiplier of exactly 2. Where a number is a convention rather than arithmetic — a code limit, a waste allowance, bundles per square — it is an input with a stated default rather than a hidden constant.

What this counts

  • Studs — one per bay at your spacing, plus one to close the far end.
  • Plates — three times the wall length: one bottom, two top.
  • Sheathing — wall area divided by 32 sq ft per 4×8 sheet, rounded up.

What it deliberately does not count

Corners, partition channels, headers, and the king, jack and cripple studs at every opening. Not an oversight — those depend on how your crew details a corner, what header schedule you are working to, and whether the wall is bearing.

A calculator that silently assumed three studs per corner and two kings per opening would produce a confident number that was wrong on most jobs. Add them per opening and per corner, from the detail you are actually building.

As a rough sense of the gap: a wall with two windows and a door, three corners and a couple of channels can easily need a dozen studs beyond the count here.

On 24 inch centres

Advanced framing at 24 on centre takes roughly a third of the studs out of a wall, and the material saving is real. It also puts requirements on what it carries — sheathing thickness, header sizing, and lining up joists and rafters over studs. Worth doing, but as a system rather than as a spacing change.

Common questions

How many studs are in a 16 foot wall at 16 inch centres?

Thirteen. Sixteen feet is 192 inches, which gives twelve bays at 16 inch spacing, and one more stud closes the far end. That is before any corners, partition channels or openings, which have to be added separately.

How much plate material does a wall need?

Three times the wall length, for a single bottom plate and a double top plate. A 16 foot wall needs 48 linear feet, which is three 16 foot lengths, before any waste for splices.

Why does this not include openings?

Because king, jack and cripple counts depend on the framing detail, the header size and how your crew details corners and channels. A number that quietly assumed one convention would be wrong more often than it was right, so openings are added per opening rather than guessed.
