Things to Consider When Choosing the Correct Louver Size for Your Shutters

Updated: Aug 24

The installation of high quality window coverings such as shades, plantation shutters, blinds, and custom covers is usually seen as a valuable addition to an office or home. However, when faced with personalizing the dimensions of your window treatments, differentiating between the various choices of louver sizes can feel confusing. This is particularly the case when you want to select the right louver size for your house. Louvers are a set of angled strips or slats, which are hung or fixed in intervals for shutters and plantation blinds.

Louver size will determine the amount of privacy, light, and ventilation that your rooms will receive and how much of a view you`ll have when the louvers are open at ninety degrees. The wider a louver is, the larger the space between the louvers will be when they are fully opened.

There are mainly four different louver sizes to choose from:

· 2.5 inches (Medium)

· 3.5 inches (Large)

· 4.5 inches (Very large)

Each one of the above louver sizes can look great in its own setting and there are no fast or hard rules on how you should select them. Very often the panel size you have selected will dictate the best louver size you should opt for.

Things to Consider When Choosing the Correct Louver Size for Your shutters

Medium Louvres (2.5 inches)

Since in most homes the shutters are normally left closed and are only adjusted to let the light in, it is probably better to choose a larger size.

The most popular louver size is 2.5 inches; this is due to the fact that it suits most windows. Medium size louvers give you a nice view of the outdoors through the custom blinds or shutters and let enough light into the room. They're ideal if you want to darken a room which gets too bright or if you want to hide an ugly view. The 2.5 inches blades don't protrude past the rear edge of the standard shutter frames and are perfect for most situations.

Large Louvres (3.5 &4.5 inches)

If you have a picturesque view and you want to maximize the amount of light coming into your home, then 3.5-inch louvers are the best selection for you. The larger louvers mean that fewer are required to cover the window and there will be more space between them for light and air when they are open. With the large louvers, the outdoor view is less obstructed and your eye is naturally drawn to the outdoors instead of concentrating on the shutters.

When considering louver size you should determine whether your preferred louver size will be obstructed by any obstacles like the window pane or window cranks when closing and opening them. Your louvers will require a defined amount of space to function and operate properly. Large louvers do protrude past the back edge of the standard shutter frame. As a result, a slightly larger frame is at times required to make sure that the blades don't hit the handles of the windows. 3.5-inch louvers suit large windows that have wide single shutter panels instead of the smaller bi-folded window panels.

The very large louver (4.5 inch) isn`t used in most situations due to the fact that it can be a little bit dominant if it`s used in the wrong settings. It`s best used in large rooms that have large openings such as floor to ceiling windows.

When choosing the right louver size for your plantation shutters, you should also consider the curb appeal of your home when viewing the shutters from outside. The architecture of your home will also have an impact on the louver slat size you should choose. Additionally, remember that the beauty of the shutters stands on its own, irrespective of what’s outside the window.
