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.
