To determine how much siding you need for a 12×20 shed, you first need to calculate the total surface area of the walls. A standard shed has four walls, so you’ll calculate the area of each wall and then add them together.

Assuming the shed has a standard height of 8 feet: calculate the area of all 4 walls: Area = perimeter {2 (12+20)} in feet x Height (8 feet) = 512 square feet. Thus, total Siding Area = 512 square feet.

So, you would need 512 square feet of siding to cover all the walls of your 12×20 shed. However, it’s a good practice to buy a little extra for any mistakes or future repairs.

For shed installation you have need different materials like wood studs, header, bottom plate, top plate, roof shingles, drywall for interior wall and siding to cover exterior surface. You have many option of materials used for siding like plywood of 1/2″ thickness of 4×8 sheets and Vinyl siding measure in squares. One square of siding equals 100 square feet.

A 12×20 shed measures 12 feet in width by 20 feet in length. The average Shed Wall height is an 8 foot high. This size of shed is small in size used to store garden tools, home equipment like lawn tractors, and gardening supplies. In addition of these, sheds can be used to store items that are not suitable for indoor storage, such as pesticides, insecticides, or herbicides, and petrol (gasoline).

A 12×20 shed measures 12 feet in width by 20 feet in length and height of wall is an 8 foot high. To measure total square footage of exterior wall multiply width and height of each exterior wall. To calculate total square footage of a 12×20 shed for siding i.e. perimeter × height = 2 (12+20) × 8 = 512 square feet.

Siding materials generally measured in “squares”. One square of siding equals 100 square feet, so multiply height x width of exterior wall, then divide by 100 for total “squares of siding you have needed”. You can select different materials on different walls. Do not subtract opening area of door and window, unless there is a very large opening.

**How much siding do i need for a 12×20 shed**

To calculate how much siding do you need, measure the height and width of each side of exterior wall. For each exterior wall area, multiply height times width, then add all the area of exterior wall to get total square footage. Divide the square footage by 100 to get the number of squares of siding needed for the wall. Always add 10% extra for safety measure to cover any waste from trimming.

A 12×20 shed will measure 12 feet width by 20 feet long and height of wall is an 8 foot high. Total square footage of exterior of 12×20 shed i.e Perimeter × height = 2(12 + 20) × 8 = 512 square footage. Formula for number of squares of siding you have needed = (Total square footage of exterior surface ÷ 100 ) + 10% extra as waste for trimming.

To figure the number of squares of siding do you need for a 12×20 shed, divide the total square footage i.e. 512 by 100 to get the number of squares of siding you needed i.e 512/100 = 5.12 squares, add 10% extra i.e 5.12 + 0.512 = 5.632 squares, round it in whole 6 squares. This is the total amount of siding you would need for a 12×20 sq ft shed.

If you want to calculate number of exterior grade plywood sheets, divide total square footage of exterior wall of shed by area of one Plywood sheet. Area of one 4 by 8 sheet of plywood of 1/2″ thickness is 4×8 = 32 sq ft. Divide 512 by 32, i.e 512/ 32 = 16 sheets.

You will need approximately 6 squares of vinyl siding for a 12×20 shed to cover exterior surface, walls, dormers and triangular shaped Gable. If you used other material to cover the walls, use 16 sheets of exterior grade plywood that measure 1/2 inch x 4 x 8. External covering requires 512 square feet of siding without subtracting the area of opening.

**How much does it cost to siding a 12×20 shed**
