The Perfect Guide Of Standard Door Size

Are you revamping your house? Or are you planning to build a new one? There are so many factors to look after when designing a new house or revamping your home or your office. One of the essential factors is “doors.” We need to decide the style of the door, in-swing or out-swing, etc. But it is also important to understand the standard door sizes, measurements, dimensions, frame cut, door material, the finishing, and more. 

The standard size of the doors would vary depending on the type of the door. It could be interior doors, french doors, exterior doors, entry doors, etc. The actual size of the door would also depend on the building or house. To fix a standard size of the door, you need to consider the door frame and understand the space of door opening and then measure the door width and height. 

Starting with essential things to keep in mind while looking for a door:

  • Door size
  • Budget
  • Door style – Swinging or Sliding door
  • A door with in-swing or out-swing
  • Texture and material of the door
  • Door finishing  

Here is how you can take door measurements: 

You need to decide if you need a pre-hung door or a slab door because measurement for both is taken in a different way. A pre-hung door comes with a door, hooked, and frame, and a slab door does not have a jamb. 

Here is how you can measure a pre-hung door. Take measurements from the interior part from one hinge to the opposite side to the other hinge where the sides of the door would stick. Don’t forget to note the measurements. Check if the door would fit well when closed by taking measurements by keeping the door open. After this minus three fourth inch, which is for flooring allowance. Note the figure. After that measure, the thickness of the door and note the figure. Take these notes with you when you go to buy the door.

Slab doors do not consist of hooks or frames so you just have to check the height, wilderness, and thickness of the slab doors.
