The height for all passage **doors** must be a minimum of 80 inches and the **standard** width **sizes** for interior **doors** are 24”, 28”, 30”, 32” and 36”. The minimum recommended **door** width to allow persons with disabilities' to pass through is 36 inches.

Keeping this in consideration, what is a standard door jamb size for 2x6 wall?

Prehung **doors** can be ordered to any **wall thickness**, but usually, 4 9/16 and 6 9/16 are **standard sizes**. I wouldn't be suprised if the stores you were in did not handle the **doors** that are the correct **width** for a **2x6 wall**. 2) add a 2" extension **jamb** onto your 4 9/16 prehung **door**.

How are doors measured?

Find the **door** size you need by following these easy steps. **Measure** for height (H) from the sill to the underside of the exterior trim at the top of the **door**. **Measure** the width at the top (W1), center (W2) and bottom (W3) of the **door** opening.
