CE Practive exam
Hello, I don't know where to get the get stud length 5 1/2'' , anyone helps me out? thanks!

This is just one of those things you have to know, but it's easy to remember.
If the nominal dimension is 1 inch, then subtract 1/4", which gives you 3/4".
If the nominal dimension is 2,3,4, or 6 inches, subtract 1/2", which can give you 11/2", 21/2", 31/2", or 51/2" respectively.
If the nominal dimension is 8,10, or 12, subtract 3/4".
The amount you subtract increases with the size of the nominal dimension.
