I hope this diagram go through. But something like this. _4_ | |__14__ | | 16 12 |____18___|
Every time there is more than a single heads in the figures it is 9' off a wall then 6' off the opposite. The question is can you space a sprinkler 16'6" in one direction and reduce the spacing in the other direction in conjunction with multiple sprinkler when using small room?

But in general, as long as you have a light hazard room that is less than 800 sf total, you can be up to 9' off of one wall and can have multiple heads in the room. You can't be 9' off of a wall with one head and then 9' off of a different wall with another head. The sketches in the Annex (or Handbook) do a pretty good job showing the different scenarios.

Based on NFPA 13(13ed)Fig A.8.6.3.2.4 I've always thought the only time you would exceed the 15'-0" spacing for a sprinkler is when you have a single sprinkler in a small room. In a situation where an L shape room 12x18 with a 4' pop out for the entry in one of the corners along the 18' side, Could you get away with 2 sprinklers or do you need 3?
