1. Measure each section
Use a tape measure to record the length and depth of each straight countertop section in feet or inches. Include any island or peninsula sections separately.
Apa itu kaki persegi Meja Dapur?
Countertop square footage is the total surface area of a countertop measured in square feet. To calculate countertop square footage, measure the length and depth of each countertop section in inches, multiply to get square inches, then divide by 144. Most kitchen countertops have a standard depth of 25.5 inches. For L-shaped or U-shaped kitchens, measure each straight section separately and add the areas together.

Cara menghitung kaki persegi Meja Dapur
To calculate countertop square footage, measure each straight section of countertop. Record the length along the wall and the depth from the wall to the front edge. Multiply length by depth to get the area. For L-shaped kitchens, measure each arm of the L separately and add the areas together.
2. Select your shape
Choose Persegi Panjang for a single straight section, or L-Bentuk for countertops that wrap around a corner. Enter dimensions for each section.
3. Dapatkan luas dan biaya
View total countertop area in square feet. Enter a price per square foot for granite, quartz, marble, or laminate to estimate total material and installation cost.

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 countertop surface area
Menggunakan pengukuran dalam kaki: Area (ft²) = Length × Depth. A countertop 8 feet long and 2.125 feet deep (25.5 inches) has 17 square feet of surface area. Measure each straight section separately and add for L-shaped or U-shaped countertops.
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.

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 measure countertop square footage?
