To determine how much drywall you need for a 1,800 square foot house, you’ll need to consider the height of the walls and whether you’re covering both walls and ceilings. To calculate the square footage of a 1800 square foot house, multiply the 1800 sq ft by thumb rule factor i.e 3.5, so, approximate square footage for drywall = 1800 × 3.5 = 6,300 square feet. Drywall typically comes in 4×8, 4×9, 4×10 or 4×12-foot sheets.

Determine the size of the drywall sheets you plan to use (4×8, 4×9, 4×10 or 4×12 feet). Divide the total square footage by the square footage of a single sheet to find out how many sheets you need.

Calculate how many drywall sheets you will need by dividing the total square footage of area by 32 (if you’re using 4-by-8 sheets), by 36 (if you’re using 4-by-9 sheets), by 40 (if you’re using 4-by-10 sheets), or by 48 (if you’re using 4-by-12 sheets).

For 4×8-foot sheets: 6,300 square feet / (4×8) square feet = 196.875 sheets. For 4×9-foot sheets: 6,300 square feet / (4×9) square feet = 175 sheets. For 4×10-foot sheets: 6,300 square feet / (4×10) square feet = 157.5 sheets. For 4×12-foot sheets: 6,300 square feet / (4×12) square feet = 131.25 sheets

Round up to the nearest whole sheet since you can’t buy a fraction of a sheet. So, you would need approximately 197 sheets of 4×8-foot drywall, 175 sheets of 4×9-foot drywall, 158 sheets of 4×10-foot drywall or 132 sheets of 4×12-foot drywall to cover a 1,800 square foot house with 8-foot high walls and ceilings. Make sure to account for waste and extra sheets for cuts and mistakes when purchasing.

In US, Canada, UK and many European countries of cold region, construction of wooden frame house is most popular. In wooden frame house construction one of the most important finishing material used is drywall construction to face the interior walls of dwellings and other buildings.

There are many size of drywall comes like 4 ft by 8 ft (4×8), 4 ft by 10 ft (4×10), 4 ft by 12 ft (4×12), 4 ft by 14 ft (4×14), or 4 ft by 16 ft (4×16). You can calculate drywall square footage by multiplying its length and width.

How much drywall do i need for 1800 square feet house?, this is hypothetical question, without knowing the design, number of room, interior, exterior wall or partition wall, edges or eves and how you can estimate drywall for 1800 sq ft house. In this article we describes calculation of amount of drywall necessary for 1800 sq ft house on thumb rule basis.

Drywall comes in many vary thickness and sizes for different projects. It is generally 4 feet (48″) wide and 8, 10, 12, 14, or 16 feet long. Their thickness are, 1/4″, 3/8″, 1/2″, or 5/8″. But standard and most common size of drywall is 4 feet wide and 8 feet in length of 1/2″ thick used for majority of residential building.

**How much drywall do i need for 1800 square feet house**

The best way to get accurate amount of drywall is to measure the total square footage of house containing area of all exterior walls, interior walls, or partition walls, ceiling area and area of edges and eves on design basis. But here we explain about thumb rule, it is not accurate sometimes, but gives approximation.

To calculate the square footage of a 1800 square foot house, multiply the 1800 sq ft by thumb rule factor i.e 3.5, so, approximate square footage for drywall = 1800 × 3.5 = 6,300 square feet, if it has more walls and ceiling it is best to take multiplication factor 4, if its more open, you can use 3.25. Add 10% for cutting and waste. Always better and cheaper to have to many sheets/ panels of drywall than too little.

To calculate how much drywall panels or sheets/boards do you need for 1800 square feet house, you simply dividing the total square footage of project i.e 6,300 sq ft by 32 (if you’re using 4×8 sheets) or by 48 (if you’re using 4×12 sheets), or by 40 (if you’re using 4×10 sheets). Such that 6,300 ÷ 32 = 196.87 sheets (197 whole sheets, add 10% of 197, i.e. 197 + 20 = 217 sheets or 6,300 ÷ 48 = 131.25 sheets (132 whole sheets, add 10% of 132, i.e. 132 + 14 = 146 sheets or 6,300 ÷ 40 = 157.5 sheets (158 whole sheets , add 10% of 158, i.e. 158 + 16 = 174 sheets.

As per thumb rule and approximation, for 1800 square feet house construction, you would need 217 sheets/ panels or boards of drywall if you’re using 4×8 sheets, 146 sheets of drywall when you are using 4×12 sheets, or 174 sheets of drywall if you’re using 4×10 sheets. The best way to get an accurate count is to always measure the square footage of house.

**How much drywall do i need for 1800 square feet**

In UK, and US drywall is typically 8’×4′ = 32 square feet, so for 1800 square feet area of walls and ceiling you need 1800/ 32 = 56.25 sheets (57 whole sheets). In practice you waste some in cutting, so add 10% extra i.e 10% of 57 = 6, add all = 57+6 = 63 sheets. Thus, you would need atleast 63 sheets of drywall of 1/2″ thickness for 1800 square feet area of walls and ceiling if you’re using 4×8 sheets.

**How many sheets of drywall do I need for 1800 square feet house**
