Transom windows are designed to let extra light into a room, especially in spaces where privacy or wall space is limited. They’re usually installed above doors or other windows, adding a decorative touch while helping brighten up entryways, bathrooms, or hallways.

• They can make spaces feel more open and airy.
• Some styles are fixed and don’t open, so they’re mainly for light and aesthetics.
• Transom windows can also complement the look of your home, offering a classic or modern accent depending on the design.

The term "transom window" comes from the architectural feature called a transom, which is the horizontal beam or bar above a door.

• Transom windows are installed right above this beam.
• Historically, these windows helped with ventilation and light before electric lighting was common.
• Today, they’re mostly used for style and daylight, but the name sticks because of their traditional placement above doors.

A fixed window is any window that doesn’t open, while a transom window refers to a specific placement—above a door or another window.

• Transom windows can be fixed or operable, but most modern ones are fixed.
• Fixed windows are used anywhere for light and views, but transom windows are mainly for adding light and style in tight or decorative spots.
• The main difference is the location and purpose: transom windows are all about letting in light above doors, while fixed windows can be installed anywhere.

Transom windows are sometimes called "over-door windows" or "clerestory windows," though clerestory windows are usually higher up on the wall.

• Other terms you might hear include "fanlight" (especially if the window is rounded) or "sidelight" (if it’s beside a door).
• Each name refers to the window’s placement and shape, so it’s good to check the style and location when shopping.

Choosing the right size depends on your space and the look you want.

• Measure the width of your door or window where the transom will go.
• Consider the height—transom windows are usually short but wide to maximize light without sacrificing privacy.
• Think about the frame color and grid style to match your décor.
• Walmart offers a range of sizes and finishes, so you can find options that fit both standard and custom openings.
