1. Measure your driveway
Record the length and width in feet. For tapered driveways, measure both the narrow and wide ends separately.
Apa itu kaki persegi Jalan Masuk?
Driveway square footage is the total surface area of a driveway measured in square feet. To calculate driveway square footage, measure the length and width in feet and multiply them together. A typical single-car driveway is 10-12 feet wide and 20-40 feet long, giving 200-480 square feet. Knowing the exact area helps you order the right amount of concrete, asphalt, or pavers and get accurate cost estimates from contractors.

Cara menghitung kaki persegi Jalan Masuk
To calculate driveway square footage, measure the length and width of the driveway in feet. Multiply length by width for rectangular driveways. For tapered driveways that are wider at one end, use the trapezoid formula: (top width + bottom width) ÷ 2 × length. For circular turnarounds, use the circle formula with the diameter.
2. Select the shape
Choose Persegi Panjang for straight driveways, Lingkaran for turnarounds, or Trapesium for driveways that taper from narrow to wide.

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.

Bentuk Persegi Panjang
Calculate driveway area for a straight driveway
Menggunakan pengukuran dalam kaki: Area (ft²) = Length × Width. A straight driveway 40 feet long and 12 feet wide has an area of 480 square feet. This is the most common driveway shape calculation.
Bentuk Lingkaran
Calculate area for a circular turnaround
Menggunakan pengukuran dalam kaki: Area (ft²) = π × radius². A circular turnaround with a 20-foot diameter (10 ft radius) has an area of about 314 square feet. Measure the full diameter and divide by 2 for the radius.
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 square footage of a driveway?
Measure the driveway length and width in feet, then multiply them together. A driveway 40 feet long and 12 feet wide is 480 square feet. For curved or tapered driveways, use the trapezoid or circle calculator option.
How many square feet is a typical driveway?
A typical single-car driveway is 200 to 480 square feet (10-12 ft wide × 20-40 ft long). A double-wide driveway is 400 to 960 square feet (20-24 ft wide × 20-40 ft long).
How much does concrete cost per square foot for a driveway?
Concrete driveway installation costs $4 to $8 per square foot on average, including materials and labor. Stamped or colored concrete costs $8 to $18 per square foot. Enter your price per square foot in the calculator to estimate total cost.
How do I calculate a curved driveway area?
For a circular turnaround, use the circle calculator with the diameter. For a curved section, approximate the shape as a trapezoid by measuring the two parallel widths and the length. For complex curves, split into sections and add the areas.
How thick should a concrete driveway be?
A standard residential concrete driveway should be 4 inches thick. For heavy vehicles or RVs, increase to 5-6 inches. The thickness affects the volume of concrete needed but not the square footage calculation.
How do I calculate asphalt for a driveway?
Calculate the driveway area in square feet using length × width. Asphalt costs $3 to $6 per square foot installed. A 480 sq ft driveway would cost $1,440 to $2,880 for asphalt paving.
