How much grass seed do I need?


Every lawn is different! Determining how much grass seed you need depends on a few factors:


  • The size of the area you would like to cover in grass
  • If you’re overseeding an existing lawn or planting a new lawn


Use this formula for calculating how much grass seed you will need: 


The length of your lawn x the width of your lawn = square footage (sq. ft.) of your lawn. 


Once you’ve calculated the square footage of your lawn, make sure to subtract any non-lawn areas like driveways, patios, or pools. You can find specific coverage amounts for Jonathan Green grass seed varieties on the front of the bag, or in the specifications tab on our product pages.
