Home / Doors / Measuring Combination Doors
To measure a combination door - From the inside of the home, remove any trim that conceals the outer
edges of the door jam.

Then simply measure outside edge of jam to outside edge of jam. (you may get something like 33-3/4",
which would be a 34" door)

Do the same for the height (include the sill plate at the bottom) (you may get something like 75-1/2", which
would be a 76" door)

Then you should be able to locate your door size on the door chart.

The rough opening/hole that the door and jam will fit into is the sizes listed on our door charts.
