To determine how much drywall you need for a 10×12 room, you’ll first need to calculate the total square footage of the walls you plan to cover. Calculate the perimeter of the room: Perimeter = 2 x (Length + Width), perimeter = 2 x (10 + 12) = 44 feet.

Calculate the total square footage of the walls: walls Square Footage = Perimeter x Wall Height. If you plan to have an 8-foot high wall: walls Square Footage = 44 x 8 = 352 square feet. Now add ceiling area 10×12 = 120 sq feet. Hence total area of 4 walls + ceiling for a 10×12 room = 352 + 120 = 472 sq feet.

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: 472 square feet / (4×8) square feet = 14.75 sheets. For 4×9-foot sheets: 472 square feet / (4×9) square feet = 13.11 sheets. For 4×10-foot sheets: 472 square feet / (4×10) square feet = 11.8 sheets. For 4×12-foot sheets: 472 square feet / (4×12) square feet = 9.8 sheets

Round up to the nearest whole sheet since you can’t buy a fraction of a sheet. So, you would need approximately 15 sheets of 4×8-foot drywall, 14 sheets of 4×9-foot drywall, 12 sheets of 4×10-foot drywall or 10 sheets of 4×12-foot drywall to cover a 10×12 room or 472 square foot area with 8-foot high walls and ceiling. 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. Others materials used are Wall studs, joist, rafter, header, bottom plate, top plate, siding and roof. Drywall construction is the application of wall without the use of cement mortar or rendering.

Drywall is also called as gypsum board, plasterboard, dry lining, wallboard, sheet rock, buster board, custard board, and gypsum panel which is made from gypsum panel sheets of calcium sulfate dihydrate, with or without additives, comes in large rigid sheets used in the construction of interior wall.

Drywall is a construction material used to create finishing of walls and ceilings. It replace the use of cement, mortar and bricks. It is sound proof, corrosion resistant, durable, fire free gypsum panel sheet. It is also used to create many design features, including eaves, arches and other architectural specialties. It’s quick and easy to install, incredibly durable, and requires only simple repairs when damaged.

In this article article we know about “How much drywall do i need for a 10×12 room”. Amount of drywall required for a 10 by 12 room will depend on square footage of each drywall panel, height of wall, and area of opening, is it is residential or commercial application. Area of opening included area of door, window and ventilation which is must subtracting from total. Height of residential building is an 8 foot high and for commercial application it may be 10 feet or 12 feet high.

There are many size of drywall like a 4 ft by 8 ft (4×8) sheet has area of 32 square feet, a 4 ft by 10 ft (4×10) sheet has area of 40 square feet, a 4 ft by 12 ft (4×12) sheet has area of 48 square feet, a 4 ft by 14 ft (4×14) sheet has area of 56 square feet, or a 4 ft by 16 ft (4×16) sheet has area of 64 square feet. You can calculate drywall square footage by multiplying its length and width.

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.

1/4″ thick drywall is ideal for creating curved wall or creating new surfaces over plaster. It is economical option for you. 3/8″ thickness of drywall is perfect for remodeling of partition wall and this can be also used for where the plaster has worn off. 1/2″ thickness of drywall is standard thickness to create walls and ceiling. 5/8″ thickness of drywall used for commercial application where soundproofing is necessary, it is also refers as firewall drywall.

**How much drywall do i need for a 10×12 room**

A 10×12 or 10 by 12 feet room has 4 walls and ceiling. Height of each wall is 8 feet, width is 10 feet and Length is 12 feet. Area of 4 walls of a 10×12 room = Perimeter × height = 2 (10+12) × 8 = 352 square feet. Area of ceiling = 10×12 = 120 square feet. Add area of walls and area of ceiling i.e. 352 + 120 = 472 sq ft. This is total square footage of room for drywall.

Estimate Drywall Sheets for a 10×12 room you will need by dividing the total square footage of 4 walls and ceiling i.e. 472 by 32 (if you’re using 4-by-8 sheets), or by 48 (if you’re using 4-by-12 sheets), or by 40 (if you’re using 4-by-10 sheets).

To calculate the square footage of a 10×12 room for drywall, multiply the width and the height of each wall and ceiling to get area in square feet, then add together all wall and ceiling area to get a total square-foot amount. This is the total square footage of your drywall you have needed.

Formula for drywall square footage = Area of all four walls in square feet + Ceiling area – (Area of door, window and ventilation). Area of wall is calculated by multiplying its width and height and ceiling area is length times width. Subtracting area of door 7×3 = 21 sq ft, window 3×4 = 12 sq ft, and ventilation 1×1 = 1 sq ft, total of 34 square footage.

**For example, how do you calculate drywall square footage for 10×12 feet room. Lets do the calculation process:**

● 1) Height of each wall = 8 feet high

● 2) Width of wall = 10 feet, and Length of wall = 12 feet.

● 3) Area of all four walls of room = Perimeter × height = 2 (10+12) × 8 = 352 square feet

● Ceiling area = Length × Width = 10′ × 12′ = 120 square feet

● Add all walls and ceiling area = 352 + 120 = 472 square footage

● Calculate area of opening, area of door = 7×3 = 21 sq ft, window area = 3×4 = 12 sq ft, ventilation area = 1×1 = 1 sq ft, total 21 + 12 + 1 = 34 sq ft

● Subtract area of all opening to get total square footage of room for drywall = 472 – 34 = 438 square footage.

● No. of 4×8 sheets = 438/ 32 = 13.6875 sheets ( whole 14 sheets), add extra 10% of 14 as waste, i.e. 14 +2 = 16 sheets

● No. of 4×10 sheets = 438/ 40 = 10.95 sheets ( whole 11 sheets), add extra 10% of 11 as waste , i.e. 11 +2 = 13 sheets.

● No. of 4×12 sheets = 438/ 48 = 9.125 sheets ( whole 10 sheets), add extra 10% of 10 as waste, i.e. 10 +1 = 11 sheets.

Thus, for a 10×12 or 10 by 12 feet room construction, you would need 16 sheets/ panels or boards of drywall if you’re using 4×8 size of sheets, or 11 sheets of drywall when you are using 4×12 sheets, or 13 sheets of drywall if you’re using 4×10 sheets.
