How do I measure an arched top wood screen door?

Don’t let the arch top scare you, correctly measuring the door is easy.  Just like a standard door, you’ll take three horizontal (width) two vertical (height) measurements, in addition to measuring the door jamb thickness. 

Looking at the diagram for guidance, the three horizontal measurements are:

• Upper Width (W1)                     
• Middle Width (W2)
• Lower Width (W3)

Height is indicated as:

• Center (H1) – measure in the center of the doorway, from the bottom of the doorway to the top of the arch
• Side (H2) – measure at the side, from the bottom of the door to the bottom of the arch

When measuring an arched top door, it’s critical to measure the center height (H1) of the door jamb at the HIGHEST POINT.  Remember – measuring is a critical step so double- and triple-check your measurements and make sure you’ve written them down correctly. 

Once you have your final measurements, choose the largest width and height.  You or your hired professional will trim the excess wood at the time of installation.

NOTE: Once it’s received, your door can be trimmed up to 3/8" on each side.   You can also trim up to 3/8” from the top and 1” from the bottom.  If you’ve measured correctly, you will have little if any trimming to do and you’re ready to move on to the next step.
