When Measuring a Door

All Measurements should be taken in INCHES

• Note what kind of door you are looking to replace.  For example
  • Interior
    • Single
    • Double
• Exterior
  • Single
  • Double
  • Front Entry Door with Sidelights
  • Patio Door
  • Measure the inside portion of the rough opening from frame to frame.
  • Measure the height of the rough opening from floor to the header.
  • For exterior doors, note what the exterior of the structure is made from.
  • If you cannot measure the rough opening
    • Measure the width from outside of casing to outside of casing.
    • Measure the height from the floor to the top of the casing.
    • Then measure the width of the casing itself.
    • Note the “Swing” of the door.
      • Swing is defined as, when facing the door from the outside, what side the hinges are located.
        • For interior doors the “outside” is where you would push open the door.

Notes:

• Rough opening – opening of the hole that the door sits in that is covered by casing.
• Casing – the molding that surrounds the door.
