The Ultimate Door Dimensions Guide (Series of 35 Charts)

A collection of colorful doors in Dublin, Ireland.

“It had a perfectly round door like a porthole, painted green, with a shiny yellow brass knob in the exact middle.” -J.R.R. Tolkien, The Hobbit

If only life were so easy for those of us who don’t live in Fairyland. Unfortunately, when building or renovating a house, barn, or commercial building, there are many other designs than a round door leading into a hobbit hole. It becomes confusing to understand which is going to actually fit the building design and work best for the people using the doors.

To add to the frustration, there are different measurements for each door based on style and the purpose of the measurement. For the layman, there’s a nominal measurement which rounds off the actual door size to a usable idea of how big it is.

For the contractor, the actual size is more important. For the builder, there’s an opening size, which dictates where the framework is positioned to allow for the installation of the specified door to be installed later.

Where are all the dimension charts?

Good question.

We created an absolute ton of highly detailed door dimension charts and tables.

Initially we put them all in this article but it was way too many so we decided to break it up into a series of articles – organized by door type.

Here’s the list.  Click the following for dimensions of the indicated types of doors:
