When you think of a window, you probably picture a simple square with a cross in the middle. It’s the classic image children draw when sketching a house. But have you ever wondered if those grids in the window actually serve a purpose?

A Critical Design

Window grids, also known as grilles or muntins, once played an important role in window construction. Before modern manufacturing, grids held together multiple small panes of glass. This made it possible to ship windows safely without the risk of large panes shattering in transit.

Today, window grids are mostly decorative—but that’s not a drawback. Grids offer timeless style and remain a popular design choice for homeowners looking to add charm and character to their windows.

Types of Window Grids

There’s more than one way to style a window grid. While the classic cross pattern may come to mind first, there are several other styles worth considering. Here are the most common options that can help you decide if grids fit your home’s look—and if so, which type is best.

Colonial Window Grid

Few styles feel more traditional than Colonial. Known for symmetry, Colonial architecture pairs perfectly with windows that highlight balance and proportion. Colonial window grids reflect this by dividing the glass into multiple squares or rectangles—often in “six-over-six” or “nine-over-nine” patterns.

If your home has Colonial roots or a boxy, traditional design, this grid style can dramatically boost curb appeal. The natural break of the sash in a double-hung window only enhances the balanced look.

Prairie Window Grid

For something distinct from Colonial symmetry, consider the Prairie style. This grid design features a large open square or rectangle in the center with narrow lines along the edges, creating smaller squares in each corner. The result is a clear view framed with just enough detail.

Prairie grids are especially striking on casement windows. Since these windows don’t open and close like double-hung styles, they provide wide, unobstructed views and plenty of natural light. The Prairie pattern enhances the look without taking away from the scenery.

Farmhouse Window Grid

The Farmhouse aesthetic is everywhere—and windows are no exception. Farmhouse grids are simple, functional, and understated, often paired with bold trim. The goal is to maximize natural light and airflow, so patterns are usually minimal.

Common designs include a four-pane look created with one horizontal and one vertical grille, or a two-over-one style with a grid only on the top sash. Both add character while keeping the design clean and bright.

The Modern No-Grid

Minimalist homes often skip grids entirely. Modern design values sleek lines and unobstructed glass, making grid-free windows a popular choice. If your goal is a crisp, contemporary look, eliminating grids will push your home’s style into the 21^st century.

Not Sure? Try Removable Grilles

With so many grid styles, it can feel like a permanent commitment. Thankfully, removable grilles give you the best of both worlds. These grilles attach to the inside of the window and can be taken off or swapped whenever you want a new look.

Removable grilles also make cleaning easier. You can enjoy the classic appearance of grids while still having the flexibility of clear glass when you want it.
