Factors to Consider when Choosing Louver Size for Window Shutters

Window shutters are a great feature for any house since they control privacy, light entering the home and ventilation. The best part is that shutters come in different materials that a homeowner can choose. However, simply going to a store and selecting a window shutter is not enough. For instance, you need to put into consideration the size of the louvres. This article highlights tips for choosing the right louvre size for your windows for optimal installation.


The backspace (window sill) is the space between the outside of a wall and the window pane. For louvres to operate optimally, the window sill should be free from obstructions such as window cranks. Therefore, it is critical to consider the size of the backspace on your window before purchasing the shutters. For example, if there is limited clearance in the backspace, then small-sized louvres are ideal because one can tilt the louvres without hitting the window sill. On the other hand, larger louvres are appropriate if the backspace is significant.

Picturesque View

The landscape on your home compound plays a critical role in determining the size of louvres for your window. If your living room window overlooks a waterfront, an impeccable garden or a view of the hills, then large louvres — 4.5 or 5.5 inches — are ideal. The reason is that with large louvres, there is some little obstruction to the window movement; therefore, the large louvres allow you to take advantage of the picturesque view outside the window. It is best to use the louvres on floor-to-ceiling windows to maximise the unobstructed view offered by large louvres. Most importantly, the bigger the windows and louvres, the better the view from the outside.


Homeowners have tastes and preferences when it comes to choosing what goes in their windows. While some homeowners want a traditional look, others will go for a contemporary style that blends well with the rest of the house. If you want a clean, modern look on your shutters, then medium-sized louvres will do the trick. While they are not small, medium-sized — 3.5 inches — are not the largest, either. For example, if you have a 72-inch wide window, then you need about four 2.5 inch louvres. However, if you install 3.5-inch louvres, you will only need two panels, which give your home window a less crowded and cleaner look than the former former setup.
