When purchasing new windows, it’s crucial to have accurate measurements of your existing window openings to ensure you’ll have the correct size for your new windows. Poorly sized windows will look awkward in your home and won’t function smoothly.

Here are the top considerations to remember when choosing a window size.

Orientation

Consider the location where the windows will be installed. For example, if you want to take advantage of the sun’s heat during winter, you can opt for a larger window oriented toward the north. However, since this can be a problem in summer when the sun is at a higher angle in the sky, you can control the sunlight and heat by shading north-facing windows with awnings and eaves.

Thermal Mass

Thermal mass is the ability of a material to absorb heat. High-density materials like brick, tile and concrete are considered to have a high level of thermal mass. They require a lot of heat energy for their temperature to change, so windows with larger areas of glass are better suited for homes made with these materials. Lightweight materials like timber, on the other hand, have low thermal mass. Homes built with these materials should have windows with smaller areas of glass.

Window Type

Windows are made in standard sizes to make shopping easier for homeowners. However, standard sizes vary depending on window styles.
