How to Measure the Overall Diameter

To find the correct replacement size, you’ll need two measurements: the overall diameter of the globe and the diameter of the opening. First, let’s measure the overall diameter. Place the plastic globe on a flat surface with one side touching the wall. Next, take a straight object and place it on the opposite side of the globe. Using a ruler, measure the distance from the wall to the edge of the globe. This measurement is your overall diameter.

How to Measure the Diameter of the Opening

Now, let’s measure the the opening. If your plastic globe is neckless (doesn’t have a neck), you can measure the width of the opening from edge to edge with a ruler. However, if your globe does have a neck, you’ll need to measure the width from the outer edges of the flange to get an accurate opening diameter.
