I just treat it that way.
How many sheets of plywood are in a square.
230 divided by 32 equals 7 19.
I use my table saw sled.
Sometimes you will end up with leftovers that are too small to use and you may need additional sheathing material.
The number of sheaths needed is based on square footage of the area and the square footage of one sheath of plywood.
Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed.
If your roof area is 1 600 square.
For example if the area to be covered in plywood is 800 ft 2 then 25 sheets of plywood will be needed to cover it.
Estimate the number of sheets needed for sheathing a wall or floor with plywood or osb.
Use the drop downs below to select a length in feet.
This calculator does not simply divide the total square footage by 32.
For example if your roof is 3 000 square feet divide 3 000 by 32.
Covering 230 square feet requires eight sheets.
For more complicated shapes see the instructions below.
Divide the total roof area by 32 to get the number of sheets you will need to cover the roof.
Plywood is a necessity in many diy and construction projects but not every type of plywood works for every project.
For example a standard sheet of plywood 8 feet long and 4 feet wide has a surface area of 32 square feet.
A 4 8 sheet of plywood is 32 ft 2.
The calculation is based on that the plywood or osb oriented strand board sheets are of a 4 x 8 size.
I will cut my widths along the 8 lengths and then us my sled to cut the 34 5 cutting a 1 4 over on my first cut and then setting to 34 5 and cutting the actual size.
The most common size for plywood sheets is 4 x 8 feet followed by 5 x 5 feet.
This basically calculates the number of sheets needed for a gable roof.
Divide by the total square footage by the square footage of a sheet of plywood to find the number of sheets required to cover the space.
Estimate the amount of plywood or osb needed for sheathing a roof.
One sheet 32 ft.
Number of sheets needed based on 4 x 8 sheet size.
Then do the same thing for the width.
The many types of plywood can differ in materials number of layers rating and grade.
If your roof has triangles and other shapes you ll need to use a calculator to find the square footage.
A typical 4 foot by 8 foot sheet of plywood covers 32 square feet.
This comes out to about 94 sheets of 4 x 8 plywood.
Divide the roof s area by 32 32 is the total area of one sheet of plywood to find this figure.
800 32 25 sheets.
A 4 8 sheet of plywood is 32 ft 2.
I have learned that the factory edge is not straight and sheets are not square.
So dividing the area of the roof by 32 will give you the number of.
