Door Glass 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.



Adding Door Glass

First, be sure your door is made of either steel or fiberglass. If you have a wood door, you may experience many more variables than shown in this guide. To get help with a wood door, it may help contacting a Zabitat sales representative.

Steel doors are metal on the outside with an insulated core. If a magnet sticks to the door, it is a steel door.

Fiberglass doors are a composite material on the outside with an insulated core, and can be smooth or have a wood grain texture to resemble wood doors.

Spotlights door glass inserts are designed to provide complete flexibility in creating a unique pattern of glass inserts in your flush door. Since your starting door is flush with no paneling, there is unlimited possibilities in how to arrange your Spotlight glass inserts to get the perfect look. Installing Spotlights will require taking accurate measurements for your cut-out areas and because of the limitless variations of glass placements and layouts, we are only able to provide examples of how to measure. The actual measurements of your door may vary.

Spotlights Door Glass

1. Door Measurements

Measurement A. Door Width

You’ll first want to find the width of your door slab. This measurement does not include the frame jamb, which is attached to the door. The best way to get this measurement is to open your door so you can get to the very edges of the door slab that normally would rest against the door jamb. Make sure to measure the width of your door at various heights because some doors may be slightly wider at the top of the door than they are at the bottom of the door (or vis-versa). Keep this in mind when marking your Spotlights cut-out area.

Measurement B. Door Height

Then you’ll want to find the height of your door slab. This measurement does not include the frame jamb, which is attached to the door. It is also best to open your door so you can get to the very top and bottom edges of the door slab that normally would rest against the door jamb. Make sure to measure the heigh of your door at various widths because some doors may be slightly taller on the left side of the door than it is on the right side (or vis-versa). Keep this in mind when marking your Spotlights cut-out area.

2. Mark Glass Layout

As stated previously, there are unlimited possibilities for arranging your Spotlights door glass inserts. Below you will find a couple examples. Additional examples of Spotlight cut-out layouts can be found in our Spotlights Installation Instructions. Majority of entry doors are either 6’8″ tall or 8’0″ tall and range from 2’6″ to 3’0″ wide. There can be slight variations in the actual size of your door. Since all doors have these slight variations, it’s important to take accurate measurements of your door and apply the variations to your calculations when marking off your cut-outs.

DOOR 1 DOOR 2 DOOR 3 DOOR 4 DOOR 5
DIM A 2′ 6″ 2′ 8″ 2′ 8″ 3′ 0″ 3′ 0″

This example layout shows the use of 1 piece of the 24″ x 12″ Spotlights Frame Kit. The table above shows example measurements based on standard door sizes (measurements A and measurements B). Variations in your door’s size can alter actual placement.
