Small rooms square footage per head whether there is one or four is determined by the area of the room divided by the number of heads in the room, NOT by the doubling the distance to a wall. Kathryn

In a single head situation for hydraulically calculated systems, 16'-6 * 13'-7½ = 225 sq ft max coverage for light hazard standard sprinklers. So it's 7'-6 off one wall and 6'-1½ off the other.

One other question, why when there's only one head can you be up to 9' off one wall and still be 7'6 off the other (16'6" direction) but when there's 2 or more heads the max you can be is 9'-0" & 6'-0"?
