Sprinkler Spacing Guidelines
❚ Square Spacing
No wind - 55% of diameter
4 mph wind - 50% of diameter
8 mph wind - 45% of diameter
❚ Triangular Spacing
No wind - 60% of diameter
4 mph wind - 55% of diameter
8 mph wind - 50% of diameter
❚ Single-Row Spacing
No wind - 50% of diameter
4 mph wind - 50% of diameter
8 mph wind - 45% of diameter
Note: Designing for zero (0) mph
wind conditions is not recommended.
Design for worst wind conditions.
