Window Grids Explained

Window Grids Explained

The curb appeal of your is extremely important upgrading your windows with grids is one way to improve the look of your home and to make it stand out among your neighboring houses. An upgrade to windows, grids are stylized strips of vinyl, wood, or aluminum that can be found either between the glass (on multi-pane windows) or on the outside of the glass. In this post, we’ll introduce you to popular grid pattern styles, grid types, and profiles. 

What Are Grid Styles?

Grids usually come in a number of different styles depending on the shape, style, and visual appeal. Though they often come in pre-designed styles, customization of these styles is also common based on your knowledge and preference. Here are some of the most common grid styles. 


Known to be one of the more traditional looks among these grid styles, colonial-style grids break up the panes into equal sections. Typically, they run in sets of 4, 6, or 9 lites which means the divider strips create the appearance of 4, 6, or 9 individual panes of glass. 


Decorative grids can easily transform your window into a showpiece. They’ll stand out compared to traditional window grids and can be customized to perfectly fit the design of your home. If you’ve tried other traditional window grid styles in the past and know what you like, going the decorative route will be more adventurous and provide endless options for your home.


The influence of the older colonial grid style pattern is clear on a farmhouse window, but there are several distinctions, one being that the most popular look on farmhouse windows is a four-pane glass approach that offers the most distinct farmhouse look. This style is usually found on double-hung windows.


Modern window grids create a sleek look perfect for contemporary homes. Simplicity is the key in modern design and you’ll find the same feel in modern window grids that feature horizontal lines. These grids are usually found on casement or awning windows, and a simple grid pattern does a lot more for the aesthetic appeal than that same pattern might do on another window type. This grid style term can be used almost interchangeably with a ‘contemporary’ grid style. 


If you’re looking to switch it up a bit, prairie-style grids can provide a unique feel since they can be divided into unequal panes. Usually, prairie-style grids have a larger square in the middle that takes up the most space while little squares go in the corners, leaving the center a bit plain. While the top and bottom sashes are allowed to be equal sizes if you choose, they don’t have to be. 

Double Prairie

As the name implies, the double prairie window grid style is very much like the prairie-style grid listed above. The key difference, however, is that there are more little squares going in the corners of these windows. The result is a smaller middle square than the one you’d likely see using a prairie-style grid. If you like the prairie style, this might offer a similar feel with a different visual touch. 

Types of Grids

Full Divided Lite

A full divided lite window has three parts to create the appearance of authentic individual lites. A full divided lite grid has applications on the interior and exterior of the window as well as a spacer between the glass. The layered grid elements carry through from exterior through to the interior side of the window inside the home. 

Simulated Divided Lite

A simulated divided lite looks similar to the full divided light except the grid bars are only adhered to the interior and exterior sides of the glass, not between the glass. Some window companies offer removable grilles instead of permanent which makes cleaning easier.

Internal Grids

Internal grids are perfect for homeowners who appreciate the look of grids but prefer low-maintenance, easy-to-clean glass. This type of grid is suspended between the panes of glass without interior or exterior grid applications. 

Removable Interior Grids

As the name suggests, removable interior window grids can be easily removed for cleaning or to change the look of your windows in a snap. Removable grids are located on the surface of the window glass accessible from inside the home. 

Grid Widths and Profiles

While there are reasonable standards for the width and profile of window grids, at the end of the day the decision comes down to what grids the window offers and what the homeowner prefers. A good rule of thumb is that grids should be proportional to their window size and offer a similar shape to maximize visual appeal (i.e. a square grid on a square window, etc.). One more thing to take into account is glass space and where you’ll actually be looking out the window–if you prefer a less obstructed view consider either no grids or grid patterns with fewer lites. 

Some window companies offer different options depending on the window series. Take a look at the chart below to see grid width options from Andersen Windows (Andersen refers to grids as grilles).

Grids are optional because they don’t affect the function of a window. That gives homeowners the liberty to design windows with or without grids. Homeowners can get creative or choose grids that are most aligned with the architectural style of their home. And the appeal boost isn’t only for homeowners–windows are one of the more prominent features seen from the outside of your home and window grids can provide additional curb appeal.
