20 Window Grid Styles for Modern Homes

Looking to add some character to your home? Perticularly, the timeless, enduring look of classic architecture? You should know that window grids make a lot of difference here.

These partitions, turning a plain sheet of glass into a pretty, patterned design, could be called the architectural equivalent of a flawless suit. And a tailored fit can really give your house the curb appeal.

In this piece, let’s walk you through 20 window grid styles you’ll actually want to look at twice. 

From Colonial Charm to Modern Edge: Top 20 Window Grid Styles for Your Home

Whether it’s geometric drama you’re after, or just barely-there simplicity, here are 20 inspirations to frame your windows with grids.

1. The Classic Colonial Grid (Six-over-Six)

If there is a stereotypical American window style, it is this one. These are the very familiar double-hung windows with a 2-by-3 sectioned grid in each sash. So both top and bottom sashes have six equal-sized panes each.

• Key Characteristics: The well-proportioned colonial grid makes it suitable for both modern and traditional homes. However, some people may find the look too busy for very conventional architecture. 

This style originated in the 18th century, when it was difficult to produce large sheets of glass. As a result, glassmakers would join several small panes to create large windows. Now, the aesthetic is mimicked using simulated divided lites (SDLs) or grilles between the glass (GBG), offering the classic look without having to join dozens of individual panes. 

2. Nine-Lite Square Grid (9-over-9)

If the 6-over-6 is the archetypal Colonial, the 9-over-9 is its gaudy, pompous brother. It splits each window sash into a full 3-by-3 grid, for a total of 18 small sections on top and bottom each.

• Key Characteristics: The higher number of sections creates a denser pattern, which obviously suggests an older, more formal pedigree. It works exceptionally well on larger windows where a six-over-six grid might look too sparse.

This grid offers a very organized and formal appearance, so people like it for the front windows of large and classically designed buildings.

3. Prairie Grid

Popularized by the architect Frank Lloyd Wright as a modern intervention, the Prairie style grid is created with bands of muntins on top, bottom, and sides, much like a “frame within a frame”. The central glass largely remains clear. 

• Key Characteristics: The maximum clear glass draws the eyes outward to the landscape while providing structural visual interest at the edges. Basically, it’s a masterclass in balance between openness and definition.

Prairie grid is considered natural and relaxed, particularly complementing low, sweeping rooflines in the living rooms, sunrooms, and other open areas.

4. Double Prairie Grid

Consider it an upgrade of Prairie style, the Double Prairie grid uses two parallel bars running on the glass, on all four sides. This adds more weight and definition to the frame, creating a bolder, more graphic statement. 

• Key Characteristics: The bold, graphic look of the double pairie is also often compared to a Mondrian painting. Especially in large windows, it enhances the landscape emphasis even further.

This style is less common than the single Prairie, usually chosen only for a custom-designed look. Best use it in great rooms with long walls to create a dynamic, grid-based focal point.

5. New England Grid (twelve-over-twelve)

Source Pinterest 

Another variation of the early American style, these windows have a 4-by-3 grid on each sash, making a total of twelve small sections on each. Out of all sectioned grids, this one is probably the most colonial. 

• Key Characteristics: This many sections create a very busy, but also highly traditional look with a charming, cottage-like feel. It’s most suitable for traditional saltbox homes, clapboard siding, and brick chimneys.

Although now you can get the design in SDL’s windows, if you really want to replicate the authentic, handcrafted character, consider windows with hand-blown glass panes with true divided lites.

6. Craftsman Grid (Top Sash Only)

The hallmark of the design is that the grid is only applied on one sash, of the hung windows, typically the top one on, while the other remains clear. The grid is often in a 2-by-2 partition, but it can be 2-by-3 or more, depending on the size of the window.

• Key Characteristics: The idea is that the bottom clear sash gives a clear view, while the top gridded one adds details to the overall look. Also, the bottom sash is often the only one operable.

Craftsman grid has roots in the 19th-century Art and Crafts movement from England. Today, it is a sought-after window grid style for bungalows, transitional farmhouses, and Foursquare homes.

7. Diamond Grid Pattern (Lattice)

These grids are created with simple crisscrossing muntins arranged in a diamond lattice across the entire window. But they can also be made equally ornate by adding decorative details and various diamond shapes.

• Key Characteristics: Diamond grids create almost a dynamic, decorative effect that can make any window a focal point. However, with some designs, they can also hide the views, making them best for windows where privacy or pure decoration is the goal.

Overall, the pattern reads somewhat medieval. But if done correctly, it makes an immediate show-stopper of a window and a perfect accent piece for dining rooms, stairwells, or casement windows.

8. Victorian Grid

There is no specific “Victorian” grid style. But a range of ornate patterns, including complex geometric layouts, carvings, and other decorative elements, are all considered Victorian window grid styles.

• Key Characteristics: Traditionally, these grids were a demonstration of handicraft and the personal uniqueness of a homeowner with patterns like sunbursts, intricate divisions, curved lines, and occasionally also a combination of stained or textured glass. You may aso see carved wooden elements and overlapping layouts.

Victorian window grids are mostly seen in Queen Anne style or High Victorian homes. The best places to use these are entryways, transoms, stairwells, and formal living rooms as accents.

9. Tall Fractional Grid

This is the modern, minimalist take on divided grids, with windows having a single horizontal muntin or small square lites only across the very top portion (like the top 1/4 or 1/6) of a tall, narrow window. The glass below is typically left clear.

• Key Characteristics: This type of grid is used to add just a hint of shape and architectural drama without compromising the expansive feel of large glass. It essentially “caps” a simple glass window for a thoughtful finished look.

Fractional grids are ideally suited for living rooms, master bedrooms, and front-facing windows where you want maximum natural light and openness.

10. Cross Grid

Source Pinterest

Probably the easiest to spot, a Cross grid has one vertical and one horizontal muntin, which intersect in the middle of the window, making the shape of a cross. The window glass is divided into four equal quadrants. 

• Key Characteristics: It offers a clean and defined look with minimal visual obstruction. You’ll most often see this type of grid on picture windows or large fixed units where a bit of breaking up is desired.

It’s a safe, classic choice mostly used in farmhouse designs and transitional homes.

11. Gothic Arch Grid

Source Pinterest

The grid for a pointed arch top window, with muntins following a radial or fanned pattern, emphasizes its unique shape. However, since the style was born in cathedrals, you may also see intricate trefoils, quatrefoils, and other ornate patterns in the arch grid. 

• Key Characteristics: Typically, the decorative arch is matched with a standard 3-by-3 or 3-by-4 divided-lite grid in the window below. But it’s not always the case. Diamond lattice, custom leaves, or even plain glass windows are also commonly seen with Gothic arch grid.

If you feel the style gives off a stronger statement than your home style, incorporate it in small doses—like in a transom window or a home chapel.

12. Segmented Arch Grid

Source Pinterest

Similar to the Gothic Arch but far less dramatic, the Segmented Arch is gently curved or flattened at the top of the window. The grid pattern in the arch typically uses simple, vertical muntins that extend upward to meet the curve. 

• Key Characteristics: Gothic arch has a graceful, rounded profile, so half-sunburst grid style often complements the curve beautifully. But it comes in another style too. The window below is typically divided into square grids.

These are frequently found in transom windows or front door combinations in homes seeking a slight deviation from the purely rectangular window.

13. Cottage Grid

Source Pinterest

The primary theme of cottage grids is the artisanship and coziness, created with small panes in repetitive square, rectangular, or triangular patterns. 

• Key Characteristics: For a characteristic look, the glass panes are organised in varying sizes or shapes within the same window, so the overall appearance is informal. However, its true sense of antiquity only comes when applied in true-divided windows with hand-crafted glass.

Although it’s an old-fashioned element, these days cottage grid windows are popular for kitchens, breakfast nooks, and cozy bedrooms.

14. Diamond-in-Cross Grid

Source Pinterest

This is a decorative pattern where a diamond shape is superimposed over a diagonal cross grid. So you get a four-petal flower pattern in the middle, nested by eight triangular panes around the edges.

• Key Characteristics:  This type of grid adds visual complexity and decorative interest, capable of turning a simple window into a focal point. Like the diamond grid, it distorts the view and is best for applications or where light diffusion is welcome.

This pattern can feel busy on large windows and is often most successful in smaller, accent windows. It is a perfect choice for adding drama and historical luxury to a restored heritage home or formal dining room.

15. Horizontal Grid

Source Pinterest

A purely modern statement, the Horizontal grid features bars running only horizontally at equal intervals across the window. It strongly emphasizes width and a streamlined look.

• Key Characteristics: Horizontal grids are rather unremarkable and only preferred when the architecture really calls for it. However, the horizontal lines do expand the spaces and make the windows feel wide.

Overall, it’s a clean-cut design that fits well in mid-century modern, contemporary, and industrial style houses.

16. Circular or Radial Grid

Source Pinterest

This window grid style is created for full circle (or half-circle) windows with grid bands running outwards like a wagon wheel or sunburst. Although the pattern can also be replicated on all types of standard window shapes.

• Key Characteristics: Circular window grid can be simple (few spokes) or complex with elaborate craftsmanship. The design success depends entirely on thoughtful placement and proportion relative to the surrounding architecture.

Since round windows are almost always fixed, non-operable windows. So this grid is often seen in accent windows in gables, above entries, or in dining rooms.  

17. Vintage Decorative Grid Style

This category includes any non-geometric, patterned grid, such as floral motifs, grape clusters, or other art patterns embedded within the grid system. The designs from the late 19th century often also feature decorative, colorful glass. 

• Key Characteristics: These types of grids are often custom-designed and come at a premium price. Once installed, they can transform a window into a work of art.

Since these grids are typically complex, they are found in fixed transoms or sidelights mostly. But of course, you can also design a vintage decorative grid for a standard casement or French pane window.

18. Perimeter / Edge-Only Grid

Source Pinterest

Also known as a “picture grid,” this style places square divisions all around the window sides. This creates a clean-lined frame at the edges with the vast majority of the glass left completely clear.

• Key Characteristics: A perimeter grid outlines the window, defining its shape against the wall without obstructing your views. It’s a clever modern compromise for homeowners to add a hint of tradition without going all-in.

The best application is on large picture windows when you want some creative rhythm across windows, but also large unobstructed views.

19. Custom Monogram or Motif

Source Pinterest

A custom window grid is the best choice for personalization, as you can put a family initial, symbol, or custom-designed motif into the window. This could become a permanent, bespoke, architectural expression of your personal or family identity.

• Key Characteristics: You’ll require close collaboration with a designer and a skilled window or glass artisan to make sure the design element actually ties with the overall aesthetics of your home. So be prepared to pay a premium for this investment.

Although you can incorporate these anywhere, the best application would be as focal points: a stairwell window, on a main entry window, or a formal study. 

20. Transom Window Grid

Source Pinterest

These are the grids designed for small, typically inoperable, windows above doors or larger windows. 

• Key Characteristics: The grid pattern should complement, not necessarily match, the main window below. These can be simple (horizontal bars) or elaborate (segmented arch, radial), depending on the size and placement of the transom. But most often, transom grids are more decorative than the companion window.

They’re ideal for narrow interior partitions, bathrooms, and above front doors where extra daylight is welcome without sacrificing privacy. 

Takeaway

Whether it is the symmetry of the Colonial, the sightly frame of the Prairie, or the rich Gothic style you desire, all types of window grid styles are now within your access. 

All you need to do is sit with your architect and choose the appropriate materials and a manufacturer such as Mannlee, who knows the ins and outs of business. And you will be good to go in making a window of your dreams.

FAQ’s

Q: What is the grid pattern in a window called?

The technical term for the bars that divide a window into smaller panes is muntins or lites (as in original true-divided-windows that hold individual glass pieces to create a grid). In modern times, the grid is mostly decorative and applied outside the glass using metal or wood grilles to mimic the aesthetic rather than structural necessity.

Q: Do window grids increase home value?

They can, when chosen correctly. Appropriate, quality grids that match your home’s architecture will enhance curb appeal and perceived craftsmanship, which are key factors for buyers. Similarly, inappropriate or poorly done grids can detract from value.

Q: Do windows without grids look cheap?

Not inherently. For modern, contemporary, or mid-century modern homes, clean, grid-less windows make an authentic and stylish choice. They look cheap only when installed on a traditional home style that may call for widow grids, making the design feel incomplete or builder-grade.

Q: What’s the difference between true divided lites and grilles between the glass?

True Divided Lites (TDL) have separate panes of glass for each lite, with muntin bars sandwiched between them. Grilles Between the Glass (GBG) are a single pane of glass with removable plastic or aluminum grilles inside the sealed airspace, offering the look with easier cleaning.

Q: Can I add grids to my existing windows?

Often, yes. You can typically install removable interior grilles that snap or clip into place on the window glass. For a more permanent exterior look, a window professional can sometimes add SDL (Simulated Divided Lite) bars to the surface fixed with the window frame.
