Replacing toilet - don't know language!

I need to replace an existing toilet. I am confused by the terminology found at the local Home Depot. The new toilet says "rough in" 12" and distance from wall 30 3/8".

I thought I read somewhere that you measure to the center of the hold down bolt to the wall. My measurement there is 12 1/2". The distance from the wall to the front of my toilet base is about 22".

Where should I be measuring from and do I need to worry about the distance from wall measurement being so long compared to my current toilet? Help!!

You're correct that the 12" rough-in refers to the distance from the wall to the center of the bolts. The 12 1/2" dimension that you have is fine for a 12" toilet.

The 30 3/8" dimension refers to the farthest edge of the toilet's rim from the wall. Unless your bathroom is small, don't be too concerned about this measurement. Just make sure that there is room for the bathroom door or shower door to clear the toilet as it is opened.
