Begin placing sprinklers in the corners of the area to be irrigated. For square areas place four quarter-circle heads in the corners as shown.
If the quarter circle heads do not reach each other, place half circle heads along the perimeter.
The two approaches to sprinkler head placement are square spacing patterns and triangular spacing patterns.
| With square spacing the heads in one row are directly across from the heads in the adjacent row. In small landscape areas, square spacing provides the least amount of over-spray outside the irrigation area. | |
| With triangular spacing the heads are positioned at the corners of an equilateral triangle. Triangular spacing provides a higher uniformity of coverage inside the irrigation area than does square spacing. | |
| With both square and triangular spacing, heads should be placed to provide head-to-head coverage, meaning the spray area of one head reaches the next head. | |

| If the perimeter heads do not spray across the area to the heads on the other side, place full circle heads in the middle of the area. | |
