Spike's Calculators

The Sheathing Cost Calculator is a user-friendly tool that efficiently estimates the amount of sheathing material required and the total cost for wall projects. Simply input the wall dimensions, including length and height in feet and inches, the area of openings, and the cost per sheath. The calculator instantly delivers the total wall area, area minus openings, the number of sheaths needed, and the overall cost. This tool is ideal for anyone looking to accurately plan and budget for construction or renovation projects involving wall sheathing.

- enter the length of the wall in feet and inches
- the height of the wall in feet and inches
- the combined square footage of the wall openings you wish to subtract
- the cost of one sheet of plywood or OSB

- the total square footage of the wall
- the square footage of the wall minus the square footage of subtracted openings
- the number of sheets needed to cover the wall
- the cost of the sheathing material (based on a 4ft x 8ft sheet size)

You need to know the wall's square footage to calculate the number of sheets needed to cover it.

The square footage of a wall divided by the square footage of the sheathing (one 4ft x 8ft sheet = 32 square feet) equals the number of sheets needed.

If your wall has a small opening, ignore it. Run the sheathing through it and cut out the opening afterwards.

For larger openings in the wall that don't need sheathing, subtract the square footage of these openings from the total square footage. However, you may waste some sheathing material and need more than the calculated amount.
