Carpet square footage is the total floor area that will be covered by carpet, measured in square feet. To calculate carpet square footage, measure the room length and width in feet and multiply them together. Carpet is commonly sold by the square yard (1 sq yd = 9 sq ft), so dividing your square footage by 9 gives the amount to order. Always add 10% for waste from seams, pattern matching, and cuts around doorways and corners.

How to Calculate Carpet for a Room
To calculate carpet for a room, measure the length and width in feet. Multiply length × width to get square footage. For L-shaped rooms, split into two rectangles and add the areas. Add 10% for waste, then divide by 9 to convert to square yards if your carpet is priced per yard.
2. Add waste factor
Enter 10% in the waste factor field to account for seams, cuts, and pattern matching. For patterned carpet, use 15-20% waste.
3. Dapatkan luas dan kos estimate
View results in square feet and square yards. Enter carpet price per square foot or square yard to estimate total material cost for your flooring project.

Formula asas
Formula Asas untuk Luas
Luas ialah jumlah ruang yang diduduki oleh bentuk 2 dimensi. Bentuk itu boleh jadi lantai, dinding, taman permainan atau padang. Formula paling mudah untuk luas digunakan untuk sebarang bentuk segi empat tepat:
Area = Length × Width
Ukur panjang dan lebar ruang dalam kaki. Darabkan dua nilai tersebut untuk mendapatkan luas dalam kaki persegi. Bilik segi empat tepat yang 12 kaki (3.66 meter) panjang dan 10 kaki (3.05 meter) lebar mempunyai luas 120 sq ft (11.15 sq m).
Ela persegi ialah luas yang diukur dalam ela, dan meter persegi ialah luas yang diukur dalam meter. Ukur dalam kaki, cari luas dalam kaki persegi, kemudian tukar kepada unit yang anda perlukan.
Untuk bilik bentuk L, bahagikan lantai kepada 2 bahagian segi empat tepat, kira setiap luas, dan tambahkan keputusan. Tukarkan semua ukuran kepada unit yang sama sebelum mendarab, jika dimensi anda dalam unit berbeza seperti inci dan kaki.

Calculate carpet area for a room
Menggunakan ukuran dalam kaki: Area (ft²) = Room Length × Room Width. Measure the longest wall for length and the perpendicular wall for width. A 12×15 room has 180 sq ft of carpet area, or 20 sq yd. Door openings do not reduce floor area because carpet extends under the opening.

Calculate carpet area for a rectangular space
Menggunakan ukuran dalam kaki: Area (ft²) = Length × Width. Use the rectangle formula for hallways, closets, or any rectangular section that needs separate carpet measurement.
Faktor pembaziran
Menambah 10% Lebihan untuk Bahan
Tambahkan 10% lebihan kepada luas yang dikira untuk mengambil kira pembaziran bahan semasa pemotongan, pecah dan pemadanan corak. Faktor pembaziran ini terpakai untuk lantai, karpet, projek jubin dan bahan landskap.

How do I calculate carpet for a room?
Measure the room length and width in feet, then multiply them together to get square footage. Add 10% for waste from seams and cuts. A 12×15 room needs 180 sq ft of carpet, or 198 sq ft with the 10% waste factor.
How much carpet do I need for a 12×15 room?
A 12×15 room is 180 square feet. With 10% waste, order 198 square feet or about 22 square yards of carpet. Carpet is typically sold by the square yard, so divide square feet by 9.
Do I need extra carpet for waste?
Yes, always add 10% to 15% extra carpet for waste. Seams, pattern matching, and cuts around corners and doorways create unusable pieces. For patterned carpet, increase the surplus to 15-20%.
How do I convert square feet to square yards for carpet?
Divide square feet by 9 to get square yards. Carpet is commonly priced per square yard. For example, 180 sq ft ÷ 9 = 20 sq yd of carpet.
How much does carpet cost per square foot?
Carpet costs $1 to $5 per square foot for materials, depending on fiber and quality. Installation adds $0.50 to $1.50 per sq ft. Enter your price per square foot or square yard in the calculator for an instant cost estimate.
How do I calculate carpet for an L-shaped room?
Split the L-shaped room into two rectangles. Calculate the area of each rectangle and add them together. Use the L-Bentuk option in the calculator to enter both sections at once and get total carpet area.
