When measuring for your new door from Glass Door Depot, please keep the following tips in mind:

• Measurements are always given width first, height second
• When measuring the width of an opening, always measure top, middle, then bottom. If these measurements are not equal, something is what we call “out of plum”
• When measuring the height of an opening, always measure right, middle, then left. If these measurements are not equal, something is what we call “out of level”
• The perfect opening is “Plum, Level, and Square”
• If your opening is not “Plum, Level, and Square”, contact us for assistance.
