Framing Lumber Calculator

Turn a measured wall run into studs, plates, blocking pieces, sheathing sheets, and rough material cost. Use it for a quick lumber list before supplier pricing or a more detailed wall plan.

Framing count is not structural design

This estimates common lumber quantities only. Headers, bracing, shear walls, fire blocking, anchors, treated lumber, loads, spans, local code, and engineered details must be checked before framing.

Framing lumber formula

Layout studs = ceiling((wall length - openings) ÷ spacing) + 1

Studs to buy = (layout studs + opening studs) × (1 + waste %)

Plate sticks = wall length × plate rows ÷ stock length

Sheathing sheets = wall area × (1 + waste %) ÷ sheet coverage

Sample takeoff

A 20 ft by 8 ft wall at 16 in spacing with one 3 ft opening, three plate rows, one blocking row, and 10% waste needs about 20 studs, 8 plate sticks, and 6 sheathing sheets.A 6 m by 2.4 m wall at 400 mm spacing with one 0.9 m opening, three plate rows, one blocking row, and 10% waste needs about 20 studs, 8 plate sticks, and 6 sheathing sheets.

Does this include headers?+
