Installing high quality window coverings is seen as a valuable addition to homes. However, deciding on the perfect louver size can sometimes be confusing. Louvers are a set of slats that are fixed in a horizontal manner fixed in intervals for shutters. They are available in different sizes – 2 ½”, 3 ½”, or 4 ½” louvers. Let us start by asking a very basic but important question – Why does the louver size matter?

The louver size matters – it has a direct effect on the level of privacy, your view of the outside and the amount of light that will be coming in through the window. Moreover, the louver size also affects the overall look of the shutter and the room.

When to pick 2 ½” louver size?

• When you have smaller windows

As a thumb rule, pick smaller louver size for smaller windows. If your window size is less than or 36” consider picking 2 ½” louvers.

• When you have less window sill depth

There should be enough clearance to open and lower your louver. Otherwise they will be hitting the window pane. If you have less clearance space, opt for 2 ½” louver.

When to pick 3 ½” louver size?

• If you want to go with the popular choice of homeowners

This size fits all medium and large windows and are a popular choice for homes as they offer a clean look.

• If you are looking for larger panels

Wider panels fit perfect with 3 ½” and 4 ½” louvers. If you have a window that is about 72” wide and you opt for 2 ½” louver, you would require minimum three shutter panels to cover the window. This increases the cost also. Whereas if you opt for 3 ½” or 4 1/2 “, you would require only two shutter panels to cover the window. This also means that you can enjoy a wider unobstructed outside view.

When to pick 4 ½“ louver size?

• Enjoy a less obstructed outside view

As we have discussed above already, wider louvers offer the best view when they are tilted to open. For medium to large windows in your homes, consider choosing 3 ½” or 4 ½” louver.

• Allow more natural light to come in

As you enjoy a wider view with a 4 ½” louver, you will also get maximum light coming in and brighten up your space.
