1. Measure bed dimensions
Record the length and width of each rectangular bed in feet. For circular beds or tree rings, measure the diameter across the widest point.
What is mulch coverage area?
Mulch coverage area is the total surface of a landscape bed measured in square feet that will be covered with mulch. To calculate mulch coverage, measure the bed length and width in feet and multiply them together. Once you know the square footage, multiply by the desired mulch depth (in feet) to get the volume in cubic feet. One cubic yard of mulch covers about 160 square feet at 2 inches deep or 108 square feet at 3 inches deep.

How to Calculate Mulch Coverage
To calculate mulch coverage, measure each bed area in square feet. Multiply length by width for rectangular beds, or use the circle formula for round beds. Once you have total square footage, multiply by mulch depth to get cubic feet, then divide by 27 for cubic yards.
2. Select the shape
Choose Persegi Panjang for straight beds or Lingkaran for round beds and tree rings. Enter dimensions and the calculator computes area automatically.

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.

The Mulch Calculator supports rectangle and circle formulas for landscaping bed measurements.
Bentuk Persegi Panjang
Calculate mulch area for rectangular beds
Menggunakan pengukuran dalam kaki: Area (ft²) = Length × Width. A rectangular flower bed 20 feet long and 4 feet wide has an area of 80 square feet. At 3 inches deep, this bed needs about 0.74 cubic yards of mulch.
Bentuk Lingkaran
Calculate mulch area for circular beds
Menggunakan pengukuran dalam kaki: Area (ft²) = π × radius². A circular tree ring with a 6-foot diameter (3 ft radius) has an area of about 28.3 square feet. Use this formula for round flower beds and tree surrounds.
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.

Jumlah Pesanan110 sq ft
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 many bags of mulch per square foot?
A standard 2 cubic foot bag of mulch covers about 12 square feet at 2 inches deep, or 8 square feet at 3 inches deep. For 100 square feet at 3 inches deep, you need about 13 bags.
How do I calculate mulch coverage?
Measure the length and width of the bed in feet, multiply to get square footage, then multiply by the desired depth in feet. A 10×20 bed at 3 inches (0.25 ft) deep needs 200 sq ft × 0.25 ft = 50 cubic feet of mulch, or about 1.85 cubic yards.
How deep should mulch be?
Apply mulch 2 to 4 inches deep for most landscaping beds. Use 2 inches for fine mulch and flower beds, 3 inches for general landscaping, and 4 inches for paths and play areas. Do not exceed 4 inches.
How many cubic yards of mulch do I need?
Calculate square footage, multiply by depth in feet, then divide by 27 to convert cubic feet to cubic yards. For 500 sq ft at 3 inches deep: 500 × 0.25 = 125 cubic feet ÷ 27 = 4.63 cubic yards.
How much does mulch cost per square foot?
Mulch costs $0.05 to $0.15 per square foot at 2-3 inches deep for bagged mulch. Bulk mulch delivered costs $15 to $65 per cubic yard. A cubic yard covers about 160 sq ft at 2 inches deep.
How often should I replace mulch?
Replace organic mulch annually or add 1-2 inches of fresh mulch each year. Bark mulch lasts 1-2 years, wood chips last 2-3 years, and rubber mulch lasts 10+ years. Replenish when the depth falls below 2 inches.
