Irrigation: Head-to-Head Coverage

By F&W Lawn Care & Landscaping · Published May 6, 2019 · Updated October 1, 2026

When you choose a company to install an irrigation system, ask whether they design for head-to-head coverage. Using fewer, stand-alone sprinklers might save a little up front, but you’ll end up with bare, brown spots during the dry months because the lawn isn’t covered evenly. Head-to-head coverage keeps watering consistent, and consistent watering leads to consistently great grass.

What Head-to-Head Coverage Means

Each sprinkler head is spaced so its spray reaches all the way to the next head. Every part of the lawn gets water from at least two directions. It sounds like overkill, but sprinklers don’t put down water evenly across their throw: most of it lands close to the head, and very little reaches the far edge. Overlap evens that out.

What Happens Without It

With heads spaced too far apart, the areas between them get only the thin edge of each spray. In June those spots look fine. By late July, they’re the first places to brown out. The usual fix is to run the whole system longer, which overwaters everything else, wastes water and invites fungus.

Other Design Details That Matter

• Matched precipitation. Heads in the same zone should put down water at the same rate.
• Separate zones for sun, shade and beds. They need very different amounts of water.
• Good water pressure. Low pressure shrinks spray distance and breaks overlap; see fixing low sprinkler pressure.
