Understanding Shutter Sizing
The size of your plantation shutters should complement your window dimensions and the overall design of your room. Whether you’re considering plantation shutters interior or other styles, accurate measurements are key.

Inside Mount vs. Outside Mount
- Inside Mount: Shutters are installed within the window frame, offering a clean and streamlined look. This option is ideal for windows with sufficient depth and provides a minimalist appearance.
- Outside Mount: Shutters are mounted on the wall or trim surrounding the window, making them suitable for windows with shallow depths or obstructions. This style can also create the illusion of larger windows.
Choosing between inside and outside mounts depends on your window’s structure and your design preferences. Depending on the depth of your window frame, you may have to choose an outside mount regardless. Check our Measurement Instructions for more details.

Measuring for the Perfect Fit
Accurate measurements are essential for ensuring your shutters fit perfectly. Here’s a general step-by-step guide:
Inside Mount
- Measure Width:
- Measure the exact width (left to right) of the inside edge of the window frame in three places (top, middle, and bottom).
- Record the smallest width of the three measurements.
- For 1/16” or 1/32” increments, round down to the nearest 1/8”. (For example, if the smallest measurement is 24 9/16,” round down to 24 1/2″. If it’s 24 3/8″, no need to round down.)
- Measure Height:
- Measure the exact height (top to bottom) of the window opening in three places (left, center, right).
- Record the smallest height of the three measurements.
- For increments of 1/16” or 1/32”, round down to the nearest 1/8”. (For example, if the smallest measurement is 24 9/16,” round down to 24 1/2″. If it’s 24 3/8″, no need to round down.)
Outside Mount
- Measure Width:
- Measure the exact width (left to right) of the inside edge of the window frame in three places (top, middle, and bottom).
- Record the largest width of the three measurements.
- If you are getting an increment of 1/16” or 1/32”, round up to the nearest 1/8”.
- You will add the frame dimensions to this size.
- Measure Height:
- Measure the exact height (top to bottom) of the window opening in three places (left, center, right).
- Record the largest height of the three measurements.
- If you are getting an increment of 1/16” or 1/32”, round up to the nearest 1/8”.
- You will add the frame measurements to this size.
Always use a steel measuring tape and double-check your measurements to ensure accuracy. Don’t worry about writing this down – each product has instructions in its “Measure and Install” tab.
Louver Size Considerations
The size of the louvers (the horizontal slats) affects both the appearance and functionality of your shutters. It determines the amount of light that shines through.
- 2 ½” Louvers: Is commonly used for smaller windows.
- 3 ½” Louvers: A traditional choice and middle ground.
- 4 ½” Louvers: Often used for deeper window frames and allows for maximum visibility to the outside
Selecting the appropriate louver size depends on your personal style and the amount of light control you desire.
