# Interior doors

> Hanging, adjusting and replacing doors inside the house. Ask with your Sheet attached: homeowners who’ve done it and verified pros answer, and anyone can read it.

## Before you ask

Prehung or slab, the rough opening, and what sticks or won’t latch.

- **Attach your Sheet** so people see your sizes and the math.
- **Your town is enough.** Never your address; check photos for house numbers and plates.
- **Is it safe?** A safety question here goes to pros verified in general contracting or carpentry, unless you pick another trade. Only they can call it safe or unsafe.

## Hang an interior door

30″ × 6′ 8″ door: a 32″ × 82-1/2″ rough opening, a 4-9/16″ jamb (for a 4-1/2″ wall), and the shims, nails, casing and knob.

What people get wrong:

- **Ordering the wrong hand.** A left-hand door can’t become a right-hand one.
- **Hinge jamb not plumb.** The door swings open or closed by itself.
- **Over-shimming.** Shims driven too hard bow the jamb, and the door rubs.
