Choose Your Lawn & Ground Cover Tool

Start with your project. Each calculator is designed to help estimate materials or watering needs using the dimensions and assumptions you provide.

Watering Calculator

Estimate how much water your garden or lawn may need based on area, target water depth, and watering frequency.

  • Enter lawn or garden dimensions
  • Estimate water volume
  • Plan a watering schedule
Use Watering Calculator →

Mulch Calculator

Work out the volume of mulch needed to cover beds, borders, and landscaped areas at your chosen depth.

  • Calculate area from length and width
  • Choose a coverage depth
  • Estimate cubic feet or cubic yards
Use Mulch Calculator →

Lawn Seed Calculator

Estimate how much grass seed to buy for a new lawn, overseeding, or patch repair using your area and seed rate.

  • Enter lawn area
  • Select a seed application rate
  • Estimate seed quantity to purchase
Use Lawn Seed Calculator →

Gravel Calculator

Calculate the approximate amount of gravel needed for paths, driveways, and decorative ground cover.

  • Measure the project area
  • Set the gravel depth
  • Estimate volume and material quantity
Use Gravel Calculator →
Planning note: Results are estimates. Actual material and watering needs vary with soil, climate, slope, grass or plant type, product instructions, and site conditions.

Plan materials before you start

Getting a useful estimate starts with measuring the area carefully and choosing realistic application depths or rates. For irregular lawns and beds, split the space into simple rectangles, calculate each section, and add the results together.

1. Measure the areaRecord length and width, and separate irregular spaces into manageable sections.
2. Choose a sensible rateUse product labels and local guidance for seed rates, mulch depth, gravel depth, or watering.
3. Check the estimateAllow for uneven ground and confirm bag sizes or delivery units before purchasing.

Lawn & Ground Cover Calculator FAQs

How accurate are these calculators?

They provide planning estimates based on the measurements and rates entered. Check product labels and local recommendations before ordering materials or setting a watering routine.

What if my lawn or garden area is irregular?

Divide the space into rectangles or other simple shapes, calculate each section separately, then add the areas together.

How much extra material should I order?

It depends on the project, product, ground conditions, and delivery units. Use the calculator result as a baseline and follow supplier guidance rather than applying one universal allowance.

Can I use these tools for every climate and grass type?

The area and volume maths is broadly useful, but watering and seed rates depend on climate, soil, grass variety, season, and product instructions. Adjust inputs to your conditions.
