Types of Exterior Doors

Pre-Hung vs. Slab Doors

Pre-hung doors include both the door and the frame that supports the door, while slab doorsi include just the door alone.

Measuring for a pre-hung exterior door can be tricky. Follow this video for specific steps. 

Tip: If your slab door is more than 25 years old, it’s best to go with a pre-hung door to ensure a sealed frame.

Pre-Hung Doors

  • Hardware (door knobs, handles and door locks) is sold separately.

When measuring your door, you must first familiarize yourself with some basic door terminology. Most entry doors are the same industry-wise standard size, while different sizes can be special ordered. See this illustration and table for reference.

  • Rough opening: the required dimensions to fit a pre-hung door (including frame and slab)
  • Jamb size: the width of the frame from front to back, covering the sheeting or siding and wall stud
  • Net frame dimension: the full width of the frame
  • Masonry opening: the space between the bricks on the front of your home as they surround the door (if applicable)

An exterior door with decorative glass.

Customize your front door with different finishes, glass panels and hardware.  


  • Decorative glass panels can be placed within a door to enhance its beauty, let in natural light, and allow for a view.
  • Sidelights (windows on both sides of the door) or transoms (windows set over the door) create a custom look. 
  • Some models include low-emissivity (low-e) coatings to help filter harmful UV rays that can fade your upholstery or flooring. 
  • Options include tempered, impact-resistant glass, glass that limits UV rays, and glass that helps muffle sound.


Doors are available unfinished, primed, painted, stained or varnished. 

Tip: The Home Depot does not apply paint, stain or varnish to doors. Seal and finish all six sides of your door (top, bottom, front back and sides) immediately after installation. Waiting to seal your door may void your product warranty.  

Door Knobs, Handlesets and Door Locks 

All exterior doors should have a deadbolt lock to increase security. A good deadbolt lock extends at least one inch beyond the edge of the door.  

Tip: For a coordinated look, choose the same finish for your door knobs, hinges, threshold, handleset, mailbox and house numbers.
