Study Notes
- Start with a plan or sketch to estimate building materials for a wall frame.
- Determine the on-center spacing of wall studs and note any corners or intersections.
- Calculate the linear feet needed for the plates by multiplying the total length of the wall times 3 and adding 5 to 10 percent for waste.
- Determine the number of studs needed by multiplying the total wall length by 0.75 for 16-inch on-center stud spacing and adding studs for specific elements.
- Headers for standard-size doors and windows often use two pieces of 2x12 lumber and one piece of 1/2-inch-thick plywood cut to the same size as the header.
- Add extra stud material for fire blocking, structural connections, window sills, temporary bracing, and other additional elements, as needed.
- To estimate sheathing, calculate the total area of the wall and subtract the area of openings.
- Divide the result by 32 and round up to the nearest whole number to determine the number of sheets needed to cover one side of the wall.
- A 13% tax should be added for interior and exterior finishes of a residential house.
- Consider tacking a few extra studs onto the final number to prevent delays if unreliable or poor-quality studs are mixed in with the order.
