What Size External Shutters Should Be?

Exterior shutters are a decorative addition to any home, but their size is crucial for their authenticity and proper finishing. They should be sized and shaped to cover the window opening when closed, folding tightly between the exterior window casings, leaving a narrow gap at the perimeter. Properly sized shutters can help prevent the appearance of the house from looking small or too cluttered.

When planning an exterior shutter project, it is essential to measure for the perfect fit. The shutters should measure the same height as the inside of the window frame, with the bottom of the shutter installed even with the top of the window sill. For door shutters, measure inside of the frame.

The width of each shutter should be half of the width of the window opening, as functioning shutters would have completely covered the window when closed. Smaller shutter widths can help prevent the house from looking small or too cluttered. Typically, the width of your shutters should be half of your total window width, but vinyl shutters are available in a handful of sizes. In choosing the width of your exterior shutters, consider the width of the window and the distance the windows are spaced apart.

Shutters should not be bigger than the window/frame, but they should also not be too small, only covering a portion of the window. The most common way to measure for decorative shutters is to measure the window trim and install shutters that are the entire height of the trim. Measure the opening along the top of the window and then measure along the bottom.

In summary, selecting the right shutter size and shape is crucial for a visually appealing and authentic exterior shutter project. By following these guidelines, you can ensure the perfect fit and aesthetic appeal of your exterior project.
