When measuring for plantation shutters, precision is key to ensuring they fit well, look great, and function properly. Incorrect measurements can lead to gaps, misaligned panels, or shutters that don’t close as they should. Here’s a quick guide to help you get it right:
- Choose Mount Type: Decide between inside mount (fits within the window frame, sleek look) or outside mount (covers the frame, hides imperfections).
- Tools You’ll Need: Measuring tape, carpenter’s square, and a level.
- Inside Mount Measurements:
- Measure width at the top, middle, and bottom; use the smallest number.
- Measure height on the left, center, and right; use the smallest number.
- Check window depth (minimum 1.5 inches clearance needed).
- Outside Mount Measurements:
- Measure width and height of the coverage area, including trim or molding.
- Use the largest measurements for full coverage.
- Account for Obstacles: Note any handles, locks, or uneven frames that could interfere with shutter operation.
- Double-Check Everything: Measure twice, record exact numbers, and ensure accuracy.
How to measure for plantation shutters
Choosing Your Mount Type
Before diving into measurements, decide how the shutters will attach to your windows. This choice not only influences the measurements you’ll take but also the overall look and functionality of your shutters. While outside mount plantation shutters are the go-to option for about 85% of installations[8], the best choice depends on your window’s structure and your personal style preferences.
Inside Mount
If you’re looking for a sleek and fitted look, inside mounts might be your best bet. These shutters sit snugly within the window frame, offering a streamlined appearance that emphasizes the window’s trim and maximizes the visible glass area[5][7].
However, inside mounts come with specific requirements. Your window frame needs a recess depth of at least 70mm (about 2.75 inches)[3]. This ensures the shutter mechanism fits securely without interfering with the window’s operation. Additionally, inside mounts work best when the window frame is perfectly square and in good condition. Any imperfections in the frame will be more noticeable, as this mounting style doesn’t hide flaws[4].
Inside mounting is ideal if:
- Your window frames are deep enough to accommodate the shutters.
- You want to highlight decorative trim around the windows.
- Your windows don’t tilt inward for cleaning.
Another perk? Inside mounts typically require less material and are easier to install, which can make them a more budget-friendly option[5].
Outside Mount
If your window frames are uneven, shallow, or have other quirks, outside mounts offer a more forgiving solution. These shutters attach to the wall or trim, extending beyond the window opening. The result is a bold, framed look that can disguise imperfections in older or damaged windows[2][5][7].
Outside mounts are incredibly versatile and work with any window type, regardless of frame depth or irregularities. They also maintain full window functionality, so tilt-in windows can still open and close without interference[4]. Plus, when the shutters are open, they don’t obstruct the window, providing an unobstructed view[4].
Key benefits of outside mounts include:
- Enhanced light control and privacy, as the shutters cover the entire window opening and extend slightly beyond it[5][6].
- The ability to hide flaws or unusual shapes in the window frame.
- Flexibility in measurements, giving you more freedom to customize the shutter size based on your design goals[9].
This option is especially practical if you:
- Have shallow or uneven window frames.
- Need to cover windows that tilt inward for cleaning.
- Want maximum light control and privacy.
- Are dealing with obstructions or unique window shapes that make inside mounting challenging.
Once you’ve settled on the best mounting style for your windows, you’re ready to gather the tools and start preparing for the installation process.
Tools and Setup
Getting accurate measurements starts with a well-prepared workspace. This helps avoid errors and ensures your shutters will fit just right.
What You Need
Grab a carpenter’s square to check if your window corners meet at perfect 90-degree angles. This step is crucial for making sure your shutters fit snugly and evenly[1].
Once you have your tools ready, it’s time to set up your workspace.
Getting Ready
Begin by clearing the area around your windows. Move furniture, take down curtains, blinds, and any decor that might get in the way[10]. If there are existing window treatments, remove them completely to expose the window frame[10][11].
Next, clean the windows and frames. Wipe down the glass and dust off any debris from the frame to ensure a clean surface for measurements[10][11]. Make sure you have easy access to the windows. If you’re planning a fit check, set up a soft surface nearby to protect the shutters from scratches while handling them[11].
How to Measure Your Windows
Taking accurate measurements is the first step to ensuring your shutters fit perfectly. Since windows aren’t always perfectly square, it’s a good idea to measure both the width and height at least twice. This extra effort can save you from costly mistakes. Here’s how to measure for both inside and outside mounts.
Inside Mount Measurements
For inside mounts, start by measuring the width of the window opening at three points: the top, middle, and bottom of the frame. Then, measure the height on both the left and right sides. Always record the smallest width and height measurements – this ensures your shutters will fit snugly, even if the window frame narrows or has slight irregularities.
Next, check the depth of the window frame by measuring from the front edge to the nearest obstruction, like a crank or lock. You’ll need at least 1.5 inches of clearance for the shutters to operate smoothly. If there are any obstructions, measure around them to account for their impact on the fit.
To ensure precision, use a carpenter’s square to check the angles of the corners. If they aren’t true 90-degree angles, note the discrepancies – this will help when customizing your shutters to fit the frame properly.
For taller windows (over 84 inches), decide where you want divider rails placed. These horizontal bars provide extra support and can enhance the design. Most people position them every 24 to 36 inches, but the exact placement depends on your window’s size and your style preferences.
By following these steps, you’ll have the precise measurements needed for a smooth installation. If you’re covering a larger area, the outside mount method might be a better fit.
Outside Mount Measurements
Outside mount shutters are designed to cover the entire window frame and part of the surrounding wall. To start, decide how much of the area around the window you want the shutters to cover. Typically, extending the shutters 2 to 4 inches beyond the frame on all sides offers better light control and a polished look.
Measure the width of the total coverage area, including any trim or molding. Take measurements at the top, middle, and bottom, and use the largest measurement to ensure full coverage.
For the height, measure from the top of your desired coverage area down to where you want the shutters to end. This could be the window sill, floor, or another feature. Measure on both sides and use the larger number to account for any unevenness.
Pay attention to details like trim, molding, or sills that stick out from the wall. Measure how far these protrude to make sure your shutter frame will clear them. If the window sill extends significantly, you may need to adjust your bottom measurement or consider an alternative mounting option.
Lastly, inspect the wall where the shutters will be installed. Use a level to check if the surface is even. If the wall is uneven, you might need special mounting hardware or frame adjustments to ensure a secure fit.
Solving Common Problems
Even with the best preparation, things like window handles, cranks, locks, and sensors can complicate your measurements. The good news? These challenges are manageable once you know how to handle them.
Working Around Obstacles
Start by identifying any obstacles in the window area. Look for things like locks that stick out from the frame, crank handles that extend into the window opening, or security sensors mounted on the glass or frame. These details matter because they can affect how your shutters operate. Make sure to account for enough clearance so the window can still function properly.
As you plan, refer back to your earlier measurement guidelines. For inside mount installations, measure the distance from each obstacle to the front edge of the window frame. If possible, consider repositioning any obstacles. If moving them isn’t an option, switching to an outside mount – where the shutters are installed on the wall around the window frame – might be the better choice.
Once you’ve handled the obstacles, it’s time to focus on addressing any uneven window dimensions.
Fixing Uneven Windows
Perfectly square windows are rare. Minor variations in size are normal, but some windows are uneven enough to require special attention. To check, measure the diagonals from one corner to the opposite corner. If the diagonal measurements differ by more than 3/8 inch, the window is considered uneven, and an outside mount is usually the best solution[12].
To confirm unevenness, measure diagonals again and note any differences over 3/8 inch. Then, measure the width at the top, middle, and bottom of the window, as well as the height at the left, center, and right. For inside mounts, use the smallest measurements. For outside mounts, use the largest.
"Windows are rarely perfectly square and there will be some variation in your measurements. Do not take any deductions, we will figure this out for you during manufacturing process."
Shallow Frame Solutions
Shallow window frames present another challenge. If your frame doesn’t have enough depth for an inside mount, an outside mount can save the day. With an outside mount, shutters are attached to the wall or casing around the window. This not only solves the depth issue but also hides imperfections in the frame and provides a clear view when the shutters are open[2][4].
Switching to an outside mount changes your measuring process. Instead of focusing solely on the window opening, measure the entire area you want the shutters to cover. Before committing, make sure there’s enough flat wall space for the installation and confirm that the wall is level and sturdy enough to support the shutters.
Outside mounts are often quicker to install and offer a clean, consistent look across multiple windows[2].
Getting Measurements Right
When it comes to plantation shutters, precision is everything. Even minor measurement errors can lead to gaps, binding, or shutters that simply don’t work as intended. By taking the time to verify your measurements and recording them correctly, you can avoid costly mistakes and unnecessary delays.
Check Your Work
Measure twice, record once. This timeless carpenter’s rule is especially relevant here. After taking your initial measurements, go through the process again. Compare the second set of numbers with the first. If they match, you’re good to go. If not, measure a third time to identify and correct any discrepancies.
"Double-checking measurements is crucial for ensuring a perfect fit for custom plantation shutters" [13]. Accurate measurements are key to proper function, smooth operation, and even energy efficiency [13].
If you’re planning an inside mount, pay close attention to diagonal measurements. If the diagonals differ by more than 3/8 inch, your window isn’t square, and you’ll need to account for this during the planning stage.
To keep things organized, create a chart for your measurements. Include spaces for width (top, middle, bottom) and height (left, center, right). This system will help you identify any inconsistencies and ensure you capture all the essential dimensions.
Give Exact Numbers
When jotting down your measurements, be as precise as possible. Write down the exact numbers you see – don’t round up or down. For instance, if your measurement is 35 3/8 inches, record it exactly as that. Shutter manufacturers rely on these precise figures to calculate the correct shutter size and to allow for any necessary clearances during production.
Stick to fractions instead of decimals. For example, if your digital tool reads 35.375 inches, convert it to 35 3/8 inches.
Round to the nearest 1/8 inch if your measurement falls between increments. Avoid estimating beyond your tool’s accuracy, as this can introduce errors.
Once your basic measurements are complete, adjust for any specific window features.
Consider Sills and Frame Position
Window sills can significantly influence how you measure and how your shutters are constructed. Determine whether the bottom of your window has a sill, as this will affect both the measurements and how the shutters are made [14].
- For inside mounts with a sill, measure the height from the top of the sill to the inside of the recess [14]. This ensures your shutters will fit snugly without gaps.
- For outside mounts with a sill, begin your height measurement at the top of the sill [14]. This method ensures the shutters provide full coverage for the window opening, accounting for the sill’s projection.
If there are obstructions, note the distance from the window to the front edge of the obstruction and the recess. The difference between these measurements will help you determine the necessary clearance [14].
As a general rule, you’ll need 2 to 3 inches of clearance between an obstruction and the edge of the recess to mount your shutters inside [14]. If this clearance isn’t available, an outside mount is usually the better option.
Conclusion: Getting Perfect Shutter Fit
Getting the right measurements is the cornerstone of well-fitted plantation shutters. From deciding between inside or outside mounts to factoring in window sills and obstructions, every step in this guide plays a role in ensuring your shutters not only look great but also function seamlessly for years.
Before placing your order, take a moment to review and double-check every measurement. Confirm the dimensions of each window and account for any potential obstructions like trim, vents, or light fixtures. This final review can save you from unnecessary delays and expensive remakes.

FAQs
Should I choose an inside mount or an outside mount for my plantation shutters?
Choosing between an inside mount and an outside mount for your plantation shutters comes down to your window’s design and the style you’re going for.
- Inside mount shutters fit snugly within the window frame, giving a polished, built-in feel. They work best for windows with enough depth and offer a clean, understated look.
- Outside mount shutters are installed on the wall or trim outside the window frame. These are a great choice for windows with shallow frames or uneven edges. Plus, they can hide flaws and add a bold, decorative touch.
Think about your window’s structure and the overall vibe you want to achieve. If you’re unsure, a professional can help you find the perfect fit.
What should I do if my window frame is uneven or has obstructions that could affect shutter installation?
If your window frame isn’t perfectly straight or has obstacles, start by measuring the width and height in several spots. Use the smallest measurements to ensure the shutters are crafted to fit snugly.
For uneven frames, shims or spacers can help close gaps and create a level surface for installation. If there are obstructions, measure the distance from the window to the obstruction and subtract it from the recess depth. This will give you the exact space available for the shutters, ensuring they fit properly despite any challenges.
When the unevenness or obstructions are more extreme, it might be worth reaching out to a professional. Their expertise can provide custom solutions, ensuring your plantation shutters fit perfectly and look seamless.
How do I take accurate measurements to ensure my plantation shutters fit perfectly?
To make sure your plantation shutters fit like a glove, start by grabbing a sturdy steel tape measure for accurate results. Measure the width of your window in three spots: top, middle, and bottom. Then, do the same for the height: left, center, and right. For the best fit, write down the narrowest width and the tallest height – these are the dimensions you’ll use.
Next, check if your window is perfectly square by measuring diagonally from one corner to the opposite corner. If the two diagonal measurements don’t match, make a note – it could impact how the shutters fit. Don’t forget to look for any hardware or obstructions around the window that might interfere with installation. Finally, double-check every measurement to avoid mistakes and ensure your shutters fit perfectly.
