Patio and garden calculators

Paver, Turf and Lawn Calculators

Start with the area: the lawn area calculator measures any shape, and the other calculators turn it into pavers, sand, flagstone, grass seed, sod rolls, artificial turf or the time and cost of mowing. Prices are yours to enter, so costs are never based on someone else’s average.

Tools in this group

  • Artificial Turf Installation Cost Calculator — Enter the lawn size and roll width to see the turf to order, seams and infill, then type your quotes to add up the installed cost. No prices are built in.
  • Concrete Block Dimensions — Pick a block thickness, height and length to see its nominal and actual size in inches and millimeters, and how long and high a wall of whole blocks comes out.
  • Flagstone (Flagging) Calculator — Enter the area and stone thickness to see how many tons of flagstone to order, shown as a range because suppliers publish different coverage per ton.
  • Grass Seed Calculator — Pick your grass and whether you are starting a lawn or overseeding, enter the area, and see pounds of seed and bags from published extension rates.
  • Measure My Lawn: Lawn Area Calculator — List the shapes that make up your yard, one per line, and subtract the house, patio and beds. You get square feet, square yards, acres and square meters.
  • Lawn Mowing Cost Calculator — Enter the lawn size and the mower width and speed to see how long a mow takes, then add your own hourly rate or a quote to get the cost per mow and per season.
  • Paver Base Calculator — Enter the paved size and the compacted base depth. You get cubic yards and tons of crushed base, the bedding sand under the pavers and the fabric area, with the depth ranges published guides give.
  • Paver Calculator — Enter the area and pick a paver size, joint width and extra for cuts to see how many pavers to buy, how many fit in a square foot, and the cost at your own price.

  • Paver Patio Cost Calculator — Pick a patio size, then type the prices you have been quoted. The page counts the pavers and edge length and adds your prices into a total and a cost per square foot.
  • Paver Sand Calculator — Enter the paved area and the thickness of the bedding layer to see cubic feet, cubic yards, tons and bags of sand, and how many bags of joint sand to sweep into the joints.
  • Sod Calculator — Enter the lawn area and how your sod is cut. You get the rolls or slabs to order, the pallets, and a cost if you type your price.
