Types of Window Shapes

When considering window replacement, homeowners have many types of windows to consider. There are fixed windows you can’t open, double hung windows with moving sashes, and casement windows that swing in and out using a crank. Sliding windows that move on tracks are common too. But special shaped windows provide opportunities to be even more creative; paired with other types, they can add to your home’s architectural style and curb appeal. And just like other windows, uniquely shaped ones can be just as suited for energy efficient homes.

Types Of Window Shapes

Special shape windows provide an even greater durability advantage because they are stationary. They don’t have moving parts that can wear out. There is a wide variety of options to consider, depending on many factors. Special shape windows on the market include:


Triangle windows can have even sides or a right triangle design. Available in standard and custom sizes, they can be fit in bathrooms, stairways, and closets to provide natural lighting, whether installed alone or in combination with regular windows. Numerous materials, color, finish, and styling options are available. Materials include wood, vinyl, aluminum, and fiberglass.


Also effective at allowing natural light into your home, oval windows come in all shapes and sizes. Top considerations include the jam height and rough vertical opening, and jamb width and rough horizontal opening. An oval window can be customized in different colors, finishes, and glass styles and provide a unique addition to the architecture and character of your home.


The shape of a gothic window is associated with the architecture of 12th to 16th century castles, upscale private dwellings, churches, and cathedrals. Its ornate beauty is sought after by many modern homeowners, builders, and architects. Some gothic windows are all wood, but aluminum -clad varieties are also available. Options include standard gothic windows or gothic windows with extended legs to expand the view and let in more natural light.


Double hung, casement, and French casement eyebrow windows are available. Although eyebrow style windows have been around since the 19th century, they have become popular options for updating homes. Benefits include a distinctive look and natural lighting, which can improve curb appeal. Eyebrow windows can be standalone or dormer windows or used as accents to other standard and special shaped windows.

Full/Half/Quarter Circle

Homeowners can install full circle windows where there is room for them. Half and quarter circle windows are suited for where space is limited, whether you can’t fit a full window or wish to accent another window or door. They can be ordered in all shapes and sizes to suit your design needs, while various designs, styles, and materials can be incorporated into the final product.


Used as a standalone window or accent to existing windows or doors, a trapezoid window provides unique aesthetics and can be ordered in any shape or size. This configuration provides a unique opportunity to adapt the style of your home to your liking. Trapezoid windows can also help your home stand out in the neighborhood.
