EXPRESS SKYLIGHT SIZES: HOW TO CHOOSE THE RIGHT FIT FOR YOUR HOME

Whether you're installing bespoke skylights or ensuring a snug fit for your existing skylights, precision in measuring the space is paramount. So it goes without saying that you need to precisely measure the space that it will be sitting in.

Accurate measurements are essential for any home feature or extension installation. Incorrect measurements can lead to drafts and ill-fitting skylights, causing issues with closure. While we provide a comprehensive full site survey prior to installation, you may opt to take on the measuring task yourself initially.

To get you started and ensure you can effectively measure your home for the correct skylight sizes, we’re going to walk you through a quick and simple process you can do yourself

WHAT ARE THE STANDARD SKYLIGHT SIZES?

Perhaps it should come as no surprise that, when it comes to standard skylight sizes, there is no one-size-fits-all measurement you can reference to make installation fast and easy.

Every home is different, and that means that each skylight measurement will be too. However, that’s not to say there isn’t an average range of skylight sizes you can turn to.

Certainly, deciding on the height and width of your skylights extends beyond mere personal preference. Various other factors warrant consideration when determining skylight size:

The size of the room you’re upgrading
The material you’re using
The location of the skylights in said room.

HOW TO MEASURE FOR A EXPRESS SKYLIGHT

Now that you have a sense of our skylight standard sizes, the next step is to measure your space accurately. We recommend following these three steps when measuring for any skylight:

Measure the width of your skylight space at the top, middle, and bottom.
Measure the length of your skylight on the right, left, and middle of the space.
Using the smallest of these measurements, subtract 10mm to allow for fitting tolerances, and use the resulting total as your base measurements.

It's essential to repeat these steps at least twice, and preferably a third time if possible. Double-checking your measurements is crucial in construction projects to minimize the risk of errors.

Additionally, if feasible, it's advisable to note the shape of the space, whether it's square or rectangular. You can determine this by measuring the diagonal distances from corner to corner. If the measurements are within 2mm of each other, you have a square opening.
