What is the correct measurement between wood deck rails & the measurement for the gap between the rails & deck?

If by correct you mean maximum, 4"

It's less than 4" allowed per current code. The code just says a 4" sphere should not be allowed to pass through.

Does it count if I was thinking "less than"????

Wasn't that you that said you must limit giving out misinformation to one post per topic:D You met your quota is all.


Thanks for the great PDF document Brandon!

No problem. I wish they had visual interpretations written up that covered other areas as well.

From Brandon's pdf (photo 17), does the following apply to deck stairways as well?

"Open risers are permitted, provided that the opening between treads does not
permit the passage of a 4-inch diameter (102 mm) sphere."

Seems like this would be a problem for just about every deck with a stairway having 30" rise or more.
