Is There A Standard Size For My Skylight?

There are many potential reasons you may be wondering if there are standard sizes for your skylights. Perhaps you are purchasing an older home and are curious how to find specific replacements for your skylights. You may be considering updating your existing home with a DIY project and want to add in sprucing up your old skylights. You may even be considering adding new skylights to your home and curious what standard skylight sizes exist! We’re here to help guide you through the process to make sure we find the perfect fit for your home.

If you have a dome skylight the potential standard rises are 4, 6, 8, 10, 12, or 14 inches. However, dome rise skylights are rarely installed in modern-day homes. That is not to say that you cannot replace your dome skylight with another dome skylight but you may want to consider more durable, energy-efficient,  modern-looking options. For rectangular fixed or vented skylights with flat tempered glass, standard sizes vary from 14-72 inches in width and 16-96 inches in length. Average skylights can vary quite a bit in weight but average around 60 pounds and can go all the way up through 150 pounds. The glass thickness of an average skylight is 1/8” to ¼.” Generally speaking the bigger the skylight the thicker the glass. However, ideally, you would have two tempered glass panes that would perform with greater energy efficiency than a single thick piece of glass. Two-tempered glass will roughly be 1” in thickness. 

Something else to consider when researching standard skylight sizes are maximum pitch restrictions. Some skylights are designed to allow for a nearly vertical pitch while others are limited to a 45, 60, or 85-degree pitch. If you find that none of the standard sizes work well for your space you are in luck! SIG Skylights is proud to offer custom skylights in varying sizes based on your specific needs.
