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

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 mulch area for rectangular beds
Menggunakan ukuran 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 Bulatan
Calculate mulch area for circular beds
Menggunakan ukuran 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 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.

Bilik dengan luas lantai 200 sq ft memerlukan 220 sq ft bahan: 200 × 1.10 = 220 sq ft. Tingkatkan lebihan kepada 15% (darab dengan 1.15) untuk corak pemasangan lantai pepenjuru atau projek jubin kompleks dengan banyak potongan.

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.
