Garage openings need header and code checks

This calculator estimates studs and plates only. Garage-door headers, bracing, portal frames, shear walls, hold-downs, fire separation, treated plates, anchors, and local code must be checked before framing.

Garage wall framing formula

Net stud run = wall run - garage door widths - other opening widths

Layout studs = ceiling(net stud run ÷ stud spacing) + 1

Opening studs = 4 per garage door or service opening for a simple allowance

Plate sticks = top plate length plus bottom plate length ÷ stock length

Sample takeoff

A 32 ft garage wall run with one 16 ft by 7 ft garage door, one service opening, 16 in spacing, 8 ft plates, and 10% waste needs about 21 studs, 10 plate sticks, and leaves about 144 ft² of framed wall area.A 9.6 m garage wall run with one 4.8 m by 2.1 m garage door, one service opening, 400 mm spacing, 2.4 m plates, and 10% waste needs about 21 studs, 10 plate sticks, and leaves about 13.0 m² of framed wall area.

Garage Wall Framing Calculator FAQ

How do I estimate garage wall studs?+

Subtract garage-door and service-opening width from the total wall run, divide the remaining run by stud spacing, add an end stud, then add simple opening studs and waste.Subtract garage-door and service-opening width from the total wall run, divide the remaining run by stud spacing, add an end stud, then add simple opening studs and waste.

Does this calculate garage door headers?+

No. Header size depends on span, loads, wall bracing, local code, and engineered details. This page only estimates common studs and plates.No. Header size depends on span, loads, wall bracing, local code, and engineered details. This page only estimates common studs and plates.

Should bottom plates run through the garage door opening?+

Usually no for the overhead door opening. This calculator subtracts garage door width from the bottom plate length for a quick takeoff.Usually no for the overhead door opening. This calculator subtracts garage door width from the bottom plate length for a quick takeoff.
