Installing your own sprinkler system is cost effective and fairly simple, but you first have to know how many sprinklers you need for your yard. You can waste money and even kill your lawn by installing more sprinklers than you need. Measure your yard and determine how many sprinklers you need to keep your lawn lush and healthy.
Things You'll Need
Measuring tape
Graph paper
Measure Your Yard
Use a measuring tape to measure the outside edges of your yard.
Draw the area of your lawn on a piece of graphing paper.
Use simple conversions, like 1 square equals 1 square foot of yard. If your yard is bigger, you can use 1 square equals 5 or 10 square feet of yard.
Placement of Sprinklers
Look on the label of your sprinkler head to determine what its radius is. Purchasing one that has a 15 foot radius will make calculating easy.
Use your graph paper to determine where your sprinklers will go.
Lay them out 15 feet apart, if you are using sprinklers with a 15 foot radius. If you are using a sprinkler with a 12 foot radius, place them 12 feet apart.
Look over the graph of your yard to make sure every area of lawn will be covered by your sprinklers.
Count how many sprinklers you have placed on your graph and purchase that many.
