If you’re planning on tackling a plywood project, you’ll need to know what size sheet to buy. Here’s a quick guide to help you make the right choice.

Sheet sizes are generally named after the number of square feet they cover, such as 4×8, 5×5, and so on. The actual dimensions of a sheet can differ slightly from these named dimensions, but they are usually very close. For example, a 4×8 sheet of plywood is usually 48 inches wide and 96 inches long.
4-foot by 8-foot
A 4-foot by 8-foot sheet is the most common size of plywood. This size is also sometimes referred to as a 2-by-4, since a standard piece of lumber is actually 1.5 inches by 3.5 inches. A 4-by-8-foot sheet of plywood is also the standard size for many building projects, including framing walls and ceilings, installing hardwood floors, and creating shelving.
5-foot by 5-foot
A 5-foot by 5-foot piece of plywood is also called a half sheet. Half sheets are generally used for smaller projects, such as building a dog house, constructing a small shed or creating hangar doors for a model airplane.
5-foot by 10-foot
plywood comes in standard 4-foot by 8-foot sheets. But when it’s cut into5-foot by 10-foot pieces, each board is actually a little bit smaller. The nominal size is the size of the lumber before it was cut into boards. The actual size is the lumber’s finished dimensions after planing and drying, which is why it’s smaller than the nominal size.
Most 5-foot by 10-foot boards are actually somewhere between 4 1/2 and 5 feet wide, and 9 1/2 to 10 feet long. The width can vary because the boards are cut from different parts of the tree, and the length can vary because of how the board is cut from the log.
Plywood is generally sold in standard sheet sizes, but can also be cut to custom sizes. The most common plywood sheet size is 4 feet by 8 feet, but 5 feet by 5 feet sheets are also available. For larger projects, 8 feet by 8 feet and 8 feet by 12 feet sheets are also available.
4-foot by 4-foot
Most full sheets of plywood come in either 4-foot by 8-foot or 5-foot by 5-foot sizes. Half sheets are half the size of a full sheet, so they are either 2-foot by 4-foot or 2.5-foot by 2.5-foot. Quarter sheets are half the size of a half sheet, so they measure either 1-foot by 2-foot or 1.25-foot by 1.25-foot.
6-foot by 6-foot
A 6-foot by 6-foot sheet of plywood is a standard size for many building projects. It is also a convenient size for storage and transportation.
Plywood is a versatile material that can be used for a variety of applications, including cabinetry, shelving, wall panels, flooring and more. It is available in a range of thicknesses, sizes and grades to suit your project needs.
8-foot by 8-foot
A standard sheet of plywood is 8 feet long and 4 feet wide. But depending on the thickness of the plywood, the sheets can vary in size. For example, a 1/2-inch sheet is actually 7-1/4 inches wide and 4 feet long.
Standard sheet sizes also vary by brand. Some companies might cut their plywood sheets a little shorter or narrower than others. So if you need an exact size, it’s best to measure theplywood before you buy it.
How to Measure
Standard sheet sizes of plywood are 4 x 8 feet, but actual measurements are 3/8, 1/2, 5/8, 3/4, 1 inch less than those dimensions. Sheets 4 feet wide and 8 feet long are called nominal plywood sizes, while the actual dimensions are called actual plywood sizes. These nominal dimensions of plywood are created so that when the boards are cut down to size and trimmed during installation, they will fit perfectly into their intended spaces.
Measure the length and width of the plywood
Plywood is generally sold in standard 4-foot by 8-foot sheets. However, many types of plywood are also available in 4-foot by 10-foot and 4-foot by 12-foot sizes. To find the number of sheets needed for a project, divide the total square footage by 32 (the square footage of a 4-foot by 8-foot sheet).
Convert the measurements to feet
Plywood is generally sold in standard 4-foot by 8-foot sheets. In some areas, it may also be available in 5-foot by 5-foot sheets. For many projects, you will need to convert the measurements to feet. Here are a few easy steps to follow:
1. Begin by measuring the length and width of the plywood in inches.
2. Convert the inches to feet by dividing by 12. (For example, if the plywood is 4 feet wide, divide 4 by 12 to get 0.33 feet.)
3. Repeat this process for the height of the plywood. (If the plywood is 8 feet tall, divide 8 by 12 to get 0.67 feet.)
4. To find the square footage of the plywood, multiply the length by the width. (In our example, 0.33 multiplied by 0.67 equals 0.22.) This will give you the number of square feet in each sheet of plywood.
Determine the square footage
Plywood comes in standard 4 x 8-foot sheets. To calculate square footage, you simply need to multiply the width by the height. In this case, 4 x 8 equals 32 square feet.
Now that you know how to determine the square footage of a sheet of plywood, you can easily calculate how many sheets you’ll need for your project. Simply divide the total square footage by 32 (the number of square feet in a standard 4×8 sheet). For example, if you’re working on a project that requires 100 square feet of plywood, you would need 3.125 sheets (100 divided by 32 equals 3.125).
