Before we dive in, let's take a quick look at what Velux skylights are and what makes them unique.

What are Velux Skylights?

Velux Skylights are high-quality and energy-efficient windows that allow natural light to flood into your home. They come in different shapes and sizes, including fixed, venting, and tubular options, providing a wide range of design and functionality choices.

Velux Skylights are designed to fit a variety of roofing materials, from standard asphalt shingles to metal roofing, and are easy to install using standard and custom flashing kits.

Now that we know a little about Velux skylights let's move on to the different sizes available.

Velux Skylights Size Options

velux skylights sizes vary based on their shape and use. The most common shapes are square, rectangular, and circular and their dimensions range from small to large sizes.

Here are the different size options currently offered by Velux:

Small Size: 14 inches by 22 inches

Medium Size: 21 inches by 45 inches

Large Size: 27 inches by 45 inches

Custom Sizes: Velux also offers custom-size skylights upon request. This option is ideal if your roof opening does not fit any of the standard sizes.

When determining the size of skylight, it is essential to consider the size of the room, the pitch of the roof, and the placement of the skylight.
