Apa itu kaki persegi Karpet?
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 biaya 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.

Rumus dasar
Rumus Dasar untuk Luas
Luas adalah jumlah ruang yang ditempati oleh bentuk 2 dimensi. Bentuknya bisa berupa lantai, dinding, taman bermain, atau lapangan. Rumus paling sederhana untuk luas berlaku untuk bentuk persegi panjang apa pun:
Area = Length × Width
Ukur panjang dan lebar ruang dalam kaki. Kalikan kedua nilai untuk mendapatkan luas dalam kaki persegi. Ruangan persegi panjang yang berukuran 12 kaki (3,66 meter) panjang dan 10 kaki (3,05 meter) lebar memiliki luas 120 sq ft (11,15 sq m).
Yard persegi adalah luas yang diukur dalam yard, dan meter persegi adalah luas yang diukur dalam meter. Ukur dalam kaki, temukan luas dalam kaki persegi, lalu konversikan ke satuan yang Anda butuhkan.
Untuk ruangan bentuk L, bagi lantai menjadi 2 bagian persegi panjang, hitung setiap luas, dan jumlahkan hasilnya. Konversikan semua pengukuran ke satuan yang sama sebelum mengalikan, jika dimensi Anda dalam satuan berbeda seperti inci dan kaki.

Calculate carpet area for a room
Menggunakan pengukuran 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.
Bentuk Persegi Panjang
Calculate carpet area for a rectangular space
Menggunakan pengukuran dalam kaki: Area (ft²) = Length × Width. Use the rectangle formula for hallways, closets, or any rectangular section that needs separate carpet measurement.
Faktor limbah
Menambahkan 10% Surplus untuk Material
Tambahkan 10% surplus ke luas yang dihitung untuk memperhitungkan limbah material selama pemotongan, kerusakan, dan pencocokan pola. Faktor limbah ini berlaku untuk lantai, karpet, proyek ubin, dan material pertamanan.

Total Material = Area × 1.10
Ruangan dengan luas lantai 200 sq ft membutuhkan 220 sq ft material: 200 × 1,10 = 220 sq ft. Tingkatkan surplus menjadi 15% (kalikan dengan 1,15) untuk pola pemasangan lantai diagonal atau proyek ubin kompleks dengan banyak potongan. Kalkulator Kaki Persegi menyertakan bidang faktor limbah untuk perhitungan ini.
FAQ
Pertanyaan yang Sering Diajukan
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.
