Landscaping calculators
Mulch, gravel, soil and outdoor material calculators.
- Paver Calculator — Pavers, Base, and Bedding SandEnter the finished patio size, installed paver dimensions, joint width, excavation margin, and both layer depths to produce a three-line material plan: pavers, crushed-stone base, and bedding sand.
- Landscaping Calculator — Multi-Zone Material PlannerMeasure up to six landscape zones, keep unlike materials separate, and turn supplier coverage or sale increments into an auditable purchase plan.
- Mulch Calculator — Bags vs Bulk CostEnter bed dimensions, mulch depth, bag volume, supplier bulk increment, and optional real prices to compare independently rounded bag and bulk material orders.
- Topsoil Calculator — Cubic Yards for Raised BedsEnter inside bed dimensions, unfilled soil depth, bed count, and supplier units to get exact volume, allowance, cubic-yard order quantity, and optional bag comparison.
- Sod Calculator — Pallets Needed from Square FeetMeasure the lawn, subtract hardscape and beds, enter the selected supplier’s pallet coverage, and get net area, allowance, exact pallets, whole pallets, and spare coverage.
- Gravel CalculatorEnter the area dimensions in feet and the gravel depth in inches to get the cubic yards and US tons to order, with wastage and an optional cost estimate.
How these landscaping calculators work
Each calculator starts from site measurements in feet and inches, converts them with a tested formula, shows the exact quantity and your waste allowance as separate lines, then rounds up to the package or order unit you actually buy. Prices are optional and always entered by you, so the estimate reflects your supplier rather than a national average.
Landscaping measuring guides
Step-by-step guides with worked examples and reference tables for United States.
- How Much Gravel and Sand for a Paver Patio BaseMeasure a paver patio base and bedding sand as two separate layers, each dug wider than the pavers, using depths from your plan or paver manufacturer.
- How Many Pavers Do I Need? Pieces per Square Foot by SizeHow many pavers do you need? Divide 144 by the paver's face area in square inches for pieces per sq ft, multiply by the patio area, then add waste for cuts.
- Landscaping Material Budget WorksheetJoin mulch, gravel, topsoil, sod and paver-base quantities into one quote-ready worksheet using current supplier prices you enter yourself.
- How to Measure Mulch BedsMeasure the area of mulch beds by length and width for rectangles, or radius for circular beds, then multiply by the desired depth in inches to calculate volume.
- How Many Bags Is 1 Cubic Yard of Mulch? Bulk vs. BaggedOne cubic yard of mulch is about 9 to 18 bags depending on bag size. Compare bulk delivery against bagged mulch, soil, or gravel by volume and cost.
- How Much Soil for a Raised Garden BedCalculate how much soil a raised garden bed needs from inside length, width and fill depth, split by your soil-to-compost ratio, with settling as your input.
- How Much Topsoil Do You Need for a Lawn?Estimate topsoil for a new lawn, levelling, or thin top-dressing by area and spread depth, in cubic yards and per 1,000 sq ft, with settling as your input.
- How to Measure a Gravel DrivewayCalculate gravel volume for a driveway by measuring length, width, and compacted depth. Handle multi-section drives with different thicknesses.
- How Much Gravel Do You Need Under a Concrete Slab?Calculate compacted gravel volume under a slab from its measured footprint and the base depth required by your plan, then convert it to a supplier-ready order.
- Gravel Cubic Yards to Tons: Ordering by WeightConvert gravel cubic yards to tons using the density your supplier gives you: the exact NIST unit math, why density varies, and how to order by weight.
- How to Measure Land Grading for a Cost EstimateMeasure cut-and-fill volumes for a land grading project and build a contractor-quote worksheet using your own rates, with no default prices assumed.
- How Much Gravel for a French DrainMeasure the trench and clean-stone volume for a French drain using dimensions from a qualified plan, with pipe displacement subtracted explicitly.
