Topsoil Volume, Tonnage, Coverage & Soil Depth Guide

Whether using our topsoil calculator in yards, calculating soil weight with our topsoil calculator tons, or planning garden plots with our topsoil calculator for raised beds, this handbook explains exact formulas, densities, and coverage standards.

The Topsoil Calculation Formula: Square Feet to Cubic Yards

To find the required volume with our topsoil volume calculator, multiply surface area by depth, then convert cubic feet to cubic yards:

Cubic Feet = Area (sq ft) × (Depth in inches ÷ 12)

Cubic Yards = Cubic Feet ÷ 27 [Formula: (Area in sq ft × Depth in inches) ÷ 324]

Tonnage = (Cubic Yards × Soil Density in lbs/yd³) ÷ 2,000

1 Cubic Yard27 Cu Ft

Equals 324 sq ft at 1″ depth, or 81 sq ft at 4″ depth.

Bulk Metric (UK)1,000 Litres

1 cubic metre (1 m³) equals approx. 1.31 cubic yards (1,000 litres).

Screened Topsoil Weight~1.1 Tons

1 cubic yard of dry screened loam weighs approx. 2,200 lbs.

Topsoil Calculator for Grass, Lawns & Sod Laying

When preparing a yard, applying the proper depth ensures strong root growth, water retention, and a smooth lawn grade:

Topsoil Weight Calculator: Screened Loam vs Compost Blends

Because dump truck delivery and axle weight limits depend on tonnage, our topsoil weight calculator calculates weights across common landscape materials:

  • Screened Topsoil (2,200 lbs/yd³ / 1.10 tons): Standard screened loam processed through a ½-inch vibrating trommel screen. Excellent for grading and filling.
  • Organic Garden Mix (1,800 lbs/yd³ / 0.90 tons): Enriched with aged mushroom compost, leaf humus, and peat moss.
  • Sandy Loam (2,400 lbs/yd³ / 1.20 tons): High sand content (60% sand, 30% silt, 10% clay) provides superior drainage under sod.
  • Wet / Clay Topsoil (2,700 lbs/yd³ / 1.35 tons): High moisture retention and dense clay minerals increase total delivery weight.

Topsoil Calculator UK: Metric Metres (m²), Bulk Bags & Litres

In the United Kingdom, landscaping soil is sold in metric square metres (m²), 1-tonne bulk dumpy bags (approx. 850–900 litres), and 25L/50L bags:

  • Metric Formula: Cubic Metres (m³) = Area (m²) × (Depth in mm ÷ 1000).
  • UK Bulk Dumpy Bags: 1 standard UK bulk bag contains approx. 800 to 900 litres (approx. 0.85 m³ or 1.1 cubic yards), covering approx. 17 m² at 50 mm (2″) depth.
  • British Standard BS 3882:2015: Certified manufactured and multi-purpose topsoil ensuring tested pH levels (6.5 to 8.0) and weed-free quality.

Expert answers to common questions about calculating topsoil cubic yards, converting tons to bags, depth standards for lawns, and bulk ordering tips.

Topsoil Volume, Calculations & Tools

How do I calculate how much topsoil I will need?
To calculate topsoil needed: 1. Measure the length and width of your area in feet to get total square footage (Length × Width). 2. Determine desired depth in inches (e.g. 1″ for lawn topdressing, 3″ for new sod, 8″–12″ for raised beds). 3. Multiply square footage by depth in inches and divide by 324 to get cubic yards ((Square Footage × Depth) ÷ 324). 4. Add 10% for natural settling after watering.
How to calculate volume of topsoil?
The standard volume formula for topsoil is: • In Cubic Feet: Area (sq ft) × (Depth in inches ÷ 12) • In Cubic Yards: Cubic Feet ÷ 27 [Formula: (Area × Depth) ÷ 324] • In Metric Litres: Area (m²) × Depth (mm) [e.g. 10 m² at 50 mm = 500 litres = 0.5 m³]
how much topsoil do i need calculator
Use YesMeasure's free Topsoil Calculator to calculate exact soil quantities. Simply enter your garden or lawn dimensions, select your desired depth (in inches), and the calculator will automatically output total cubic yards, cubic feet, weight in tons, and metric volume with settlement buffers.
how much topsoil calculator
A topsoil calculator is a digital landscape tool that converts 2D square footage and depth into 3D volumetric cubic yards and tons. For example, a 10×20 ft garden bed with 4 inches of soil requires 2.47 cubic yards (approx. 2.7 tons).
how many litres of topsoil do i need calculator
To calculate topsoil in litres, multiply your surface area in square metres (m²) by the depth in millimetres (mm). For example, a 20 m² area at 50 mm depth requires 1,000 litres of topsoil (equal to 1 cubic metre / 1 bulk bag, or forty 25-litre bags).
how much topsoil do i need calculator uk
For UK gardens and landscaping projects, our Topsoil Calculator UK supports both metric (m², litres, bulk dumpy bags) and imperial measurements. A standard UK 1-tonne bulk bag contains approximately 800 to 900 litres of topsoil and covers 17 m² at a standard 50 mm (2-inch) depth.

Coverage, Weights & Bag Sizes

How much will 1 ton of topsoil cover?
One ton of screened topsoil (approx. 0.9 to 1.0 cubic yard / 24–27 cu ft) covers approximately: • 300 square feet at 1-inch depth (lawn topdressing) • 150 square feet at 2-inch depth • 100 square feet at 3-inch depth (sod base) • 75 square feet at 4-inch depth (flower beds) • 25 square feet at 12-inch depth (deep raised planter).
What does 1 ton of topsoil look like?
One ton of loose topsoil forms a cone-shaped pile approximately 4 to 5 feet wide across the base and about 3 feet high in the center. It easily fits in the bed of a standard standard full-size pickup truck (or 1 standard bulk builder's bag).
How much area does 25l of top soil cover?
A standard 25-litre bag of topsoil (0.025 m³ / approx. 0.88 cu ft) covers: • 1.0 square metre (10.7 sq ft) at a depth of 25 mm (1 inch) • 0.5 square metres (5.4 sq ft) at a depth of 50 mm (2 inches) • 0.25 square metres (2.7 sq ft) at a depth of 100 mm (4 inches).
How much does a 40 lb bag of topsoil cover?
A typical 40-lb retail bag contains approx. 0.5 to 0.6 cubic feet of soil. It covers: • 6 to 7.2 square feet at 1-inch depth • 3 to 3.6 square feet at 2-inch depth • 1.5 to 1.8 square feet at 4-inch depth.
How much topsoil do I need for 600 square feet?
For 600 square feet: • At 1-inch depth (lawn topdressing): 1.85 cubic yards (approx. 2.0 tons / 67 bags of 0.75 cu ft) • At 2-inch depth (overseeding base): 3.70 cubic yards (approx. 4.1 tons) • At 3-inch depth (new sod preparation): 5.56 cubic yards (approx. 6.1 tons) • At 4-inch depth (garden beds): 7.41 cubic yards (approx. 8.1 tons).

Topsoil Characteristics, Depths & Pricing

How many inches is topsoil?
In nature, natural topsoil is the uppermost 2 to 8 inches (5 to 20 cm) of the earth's crust rich in decomposed organic matter, microbes, and plant nutrients. In landscaping, topsoil is applied at depths ranging from 1 inch (lawn topdressing) to 3–4 inches (new turf/sod) and 8–12 inches (vegetable raised beds).
How is topsoil different from soil?
Topsoil is specifically the dark, nutrient-dense top layer of soil with high organic matter, beneficial fungi, and earthy structure. General 'soil' or 'fill dirt' refers to subsoil layers found beneath topsoil, which contain high clay and rock content with little organic matter and poor drainage, making it unsuitable for plant growth without amendment.
Which is cheaper, topsoil or garden soil?
Standard screened topsoil is significantly cheaper than garden soil. Bulk topsoil costs $30 to $50 per cubic yard ($3–$4 per bag), whereas garden soil costs $50 to $85 per cubic yard ($6–$10 per bag) because it is pre-mixed with premium organic amendments, peat moss, perlite, and slow-release fertilizers.
