Andersen Storm Doors Measurement Guide | Zabitat

Storm Door Measurement Guide

The key to any successful Zabitat project, whether you’re DIYing it or we’re installing it for you,

is making sure you’ve ordered the correct item. Let us help you.

Measure twice, order once.

Storm Doors

First, verify the minimum space requirements on your existing door frame to make sure that your new storm door will fit. You will then need to take down the measurements shown in the door diagram. Then use the size chart to determine the correct door based on your measurements.


Door Height

Measure for height from the sill to the underside of the exterior trip at the top of the door.

Door Width

Measure the width at the top (W1), center (w2), and the bottom (W3) of the door opening. Use the shortest measurement when ordering, if they vary.
