Landscaping Calculators & Ground Material Tools
Plan your yard with landscaping calculators for mulch, gravel, soil, sod, seed, sand, river rock, and patio pavers.
Mulch Calculator
Use this mulch calculator to calculate cubic yards, cubic feet, and 2 cu ft bags of mulch needed for landscape borders, garden beds, and tree rings. Prevents weed breakthrough with recommended 3-inch depth guidelines.
Gravel Calculator
Use this gravel calculator to estimate aggregate quantities in cubic yards and tons for driveways, patios, French drains, and walkways. Features selectable material densities for pea gravel, crushed limestone, and road base.
Soil Calculator
Use this soil calculator to determine how much topsoil, garden blend, or compost is needed for raised garden beds, round planters, and lawn topdressing. Includes compaction settling allowances and bag size conversions.
Sod Calculator
Use this sod calculator to calculate the exact number of sod rolls and full pallets required to carpet your property with instant green turfgrass. This estimator factors in standard roll dimensions, commercial pallet coverage, edge cutting waste for curved borders, and total delivery weight so you can prepare equipment for installation day.
Grass Seed Calculator
Use this grass seed calculator to calculate the exact weight in pounds and retail bag counts of grass seed required for your lawn project. Whether seeding bare ground from scratch or overseeding an established turf canopy in autumn, this tool matches university-backed seeding rates to your specific grass species and bag package sizes.
Sand Calculator
Use this sand calculator to determine the exact volume and weight of sand needed for paver patios, above-ground pool liner bases, children's sandboxes, and masonry mortar. This calculator computes cubic yards, cubic feet, scale tonnage, and standard 50-pound retail bags with a realistic compaction allowance.
River Rock Calculator
Use this river rock calculator to calculate the exact volume in cubic yards and scale weight in tons of decorative river rock needed for landscape beds, dry river creeks, and foundation borders. Unlike organic bark mulch, smooth natural river rock never rots, resists wind blowaway, and creates permanent low-maintenance drainage solutions.
Paver Calculator
Use this paver calculator to estimate everything required to construct a durable interlocking paver patio, walkway, or driveway. This comprehensive calculator determines total paver stone counts, commercial pallets, crushed gravel sub-base volume, screeded bedding sand, and polymeric joint sand bags with precise cutting waste allowances.
Patio Calculator
Use this patio calculator to estimate all materials for outdoor patios, terraces, and garden walkways. Routes seamlessly between interlocking pavers, poured concrete slabs, pea gravel, and natural flagstone with complete sub-base compaction and drainage slope guidance.
Trade Guidelines for Landscaping & Ground Materials
Professional tips and standard industry assumptions for accurate material takeoffs and error-free estimating:
Recommended Mulch Layering
Apply shredded hardwood or bark mulch at a depth of 2 to 3 inches for flower beds. A 3-inch layer effectively suppresses weeds and retains soil moisture without suffocating plant roots. Keep mulch pulled back 3 inches from tree trunks and shrub stems.
Gravel Weight and Compaction
Crushed stone and angular aggregate compact by approximately 15% to 20% when rolled or plate-tamped. One cubic yard of crushed gravel weighs approximately 1.35 to 1.45 tons (2,700–2,900 lbs), depending on stone size and moisture content.
Topsoil Settlement Allowances
Loose delivered topsoil settles substantially after being graded, raked, and watered. Plan for a 15% settlement factor when ordering garden blend or screened fill soil for lawn grading.
Paver Foundation Requirements
Interlocking paver walkways and patios require a minimum 4-inch base of compacted crushed gravel (item #4 or road base) topped with a screeded 1-inch bedding layer of coarse concrete sand before setting pavers.
Frequently Asked Questions: Landscaping & Ground Materials
How much ground area does 1 cubic yard of mulch cover?
One cubic yard of mulch covers 324 square feet at 1 inch deep, 162 square feet at 2 inches deep, or 108 square feet at 3 inches deep. For most residential garden beds, dividing your square footage by 100 gives a safe yardage estimate.
How many tons of crushed stone do I need for a gravel driveway?
A standard 10-foot wide by 50-foot long driveway (500 sq ft) with a 4-inch compacted gravel base requires about 6.2 cubic yards. At roughly 1.4 tons per cubic yard, you will need approximately 8.7 to 9.0 tons of crushed aggregate.
How many square feet does one pallet of sod cover?
Commercial sod pallets typically contain 400 to 500 square feet of turfgrass, configured as either 50 to 60 individual slabs (16" x 24") or large continuous rolls. Always add 5% to 10% for cutting curves and trimming borders.
How do I choose between grass seed and sod?
Sod provides an instant, erosion-resistant lawn within hours but costs 3 to 5 times more than seed. Grass seed is significantly cheaper and offers deeper root development over 6 to 12 weeks, but requires intensive daily watering and weed prevention during germination.
