Buying Guide

Interior Doors


Doors are available in prehung and slab styles.  

Prehung doors install easily as they include the jamb and frame, and provide a uniform appearance.

Slab doors are more economical as they can be mounted using the existing jamb and trim.


Consult the following chart for door types, benefits and best fits.

Most interior doors are manufactured with either hollow core or solid core materials.  

Hollow core doors are lightweight and are ideal for areas that are not used very often and feature interwoven, corrugated cells used to support the outer face of the door.

Masonite and hardboards are also used for interior doors and feature a flat surface that is easier to paint.

Vinyl doors are available as a cost-effective option for sliding doors.

If you need a door that leads to a garage or attic, you may be required to install a door comprised of fire-resistant materials (consult your local building codes).

Installation Considerations

Before installing, determine the door swing direction and handle placement. Replacement doors should have the same measurements as old doors.  

1 3/8 inches is the most common depth, but other depths are available.

Standard widths include 18, 20, 24, 28, 30, 32 and 36 inches.

Standard heights include 80, 84 and 96 inches.

Customized sizes are available in a wide range of different designs.

To measure a prehung door, remove the interior casing and measure the opening.
