Door Jamb size

[MWC104]

I have to order entry doors for the garage and was curious what size jamb thickness do I buy? The Amish builders are going to be using 1/2" sheathing on the outside, 2x6 studs, and going to finish the inside with 5/8 drywall (garage is attached). I was worried the 6-9/16 jamb wouldn't be wide enough to trim out later on. Is there any reason to worry about the opening in the 8" thick concrete stem walls? The doors I want to order are solid vinyl cladding/brick molding.

I usually just buy the cheapest ones and make jam extensions on site... same with windows...but I'm cheap...

It's easier to add wood later than to cut wood off the jamb of an installed door.

The 6-9/16 jamb will work. You will cut the casing width down to fit around the door frame in the area along the stem wall.
