How do I estimate the materials to my house?

Multiply the length of the wall by height to get the square feet of the wall surface. Since most sheathing (plywood, drywall, paneling) comes in 4-by-8-foot sheets, take the square feet of one sheet (32) and use it to divide the square feet of the wall. This will equal the number of 4-by-8 sheets to cover the wall.
For example, if your new home is to be 2,000 square feet and your builder estimated that it would cost $350,000 to build, then your cost per square foot is 300,000 divided by 2,000, or $175.
