I have fitted plantation shutters in more homes than I can count, and the first question every client asks is the same.
Should you go with an inside mount or outside mount? It sounds like a small detail, but it changes the whole look and function of your window.
In this guide, I will walk you through both options in plain language.
You will learn what each mount means, when to pick one over the other, and how to avoid the mistakes homeowners make most often.
By the end, you will know exactly which mount fits your windows and your style.
What Is An Inside Mount Plantation Shutter
An inside mount plantation shutter fits neatly inside the window frame itself, sitting flush with the wall instead of covering it.
This style gives a clean, built-in appearance that many homeowners prefer for a polished, custom look.
The panels attach directly within the frame using a mounting strip, so no part of the shutter extends beyond the window opening.
For this to work well, the frame needs enough depth, usually around two and a half inches, along with reasonably square corners.
Without that space, the panels cannot open, close, or tilt properly, which is why measuring first really matters.
What Is An Outside Mount Plantation Shutter
An outside mount plantation shutter attaches directly to the wall or trim surrounding your window instead of sitting inside the frame.
The shutter panels sit flush against the surface around the window, covering the frame edges and a bit of extra wall space on all sides.
This style works well when a window frame is too shallow, uneven, or blocked by handles and tiles, since the shutter does not depend on interior depth to function.
It also offers better light blocking and privacy because the panels extend beyond the window opening itself.
Many homeowners choose an outside mount when they want a bold, framed look or need a practical fix for tricky window conditions that the inside mount cannot handle.
Which Is Better: Inside Mount Or Outside Mount Plantation Shutters?
Neither option wins outright. It comes down to your window shape and personal taste.
Best Choice For Clean Recessed Interior Look
If you want shutters that look tucked into the wall, the inside mount is the winner.
It gives a polished, custom feel that many homeowners love in living rooms and bedrooms.
Best Choice For Flexibility And Problem Windows
The outside mount saves the day when your window frame is not deep enough or is uneven. It also works well when you need full light blockage.
Quick Decision Guide Based On Your Window Type
Deep, square frames usually suit the inside mount. Shallow, uneven, or obstructed frames call for outside mount. Measure first before you decide.
When To Choose Inside Mount Plantation Shutters
Here is when this option makes the most sense for your home.
Deep And Square Window Reveals
The inside mount needs a frame depth of at least two and a half inches. Square reveals help the shutter sit flush without gaps on any side.
Minimal Obstructions Handles Tiles Trims
If your window has no handles, tile edges, or trim sticking into the frame, the inside mount will fit cleanly. Obstructions can block the panels from closing right.
When You Want A Flush Built In Finish
The inside mount gives a seamless, tailored appearance that matches the wall. It is a popular pick for homeowners who want a classic, built-in feel.
When To Choose Outside Mount Plantation Shutters
These situations call for outside mount instead of inside mount.
Shallow Or No Window Reveal Depth
When there is not enough frame depth, an outside mount is often the only workable option. It mounts directly onto the wall or trim.
Out Of Square Uneven Or Damaged Window Frames
Frames that are not perfectly square can cause gaps within the inside mount. The outside mount covers these flaws and still looks neat.
Windows With Handles Tiles Or Trim Interference
If hardware or tile gets in the way, the outside mount avoids the problem completely since it sits outside the frame.
When Maximum Light Control And Coverage Is Needed
The outside mount covers more of the window and wall, which blocks more light and adds privacy compared to inside mount.
Inside Mount Vs Outside Mount: Key Differences Explained
A closer look at how these two options compare side by side.
| Factor | Inside Mount | Outside Mount |
| Appearance | Blends into the wall for a built-in, recessed look | Frames the window and can make it appear larger |
| Light Control And Privacy | May leave small gaps depending on the fit | Blocks more light since it covers extra space around the frame |
| Installation Flexibility | Requires precise measurements and enough frame depth | More forgiving since it does not depend on exact frame depth |
| Maintenance And Usability | Easy to clean, panels may need a bit more care to avoid rubbing against the frame | Easy to clean and maintain, no rubbing concerns |
Common Mistakes When Choosing Plantation Shutter Mounts
Avoid these common slip-ups before you commit to a mounting style.
- Ignoring window depth and structure before choosing a mount
- Choosing based only on appearance instead of window fit
- Not accounting for handles, tiles, or uneven frames
- Skipping measurements and assuming both options will work
- Forgetting to check trim thickness around the window
Reveal Depth And Window Conditions Why Your Choice Depends On It
Your window's physical structure often decides which mount will actually work.
How Reveal Depth Affects Inside Mount Suitability
Reveal depth is the space between the window glass and the wall surface. Without enough depth, panels cannot open and close properly.
Minimum Space Requirements For Inside Mount Shutters
Most inside mount shutters need at least two and a half inches of depth. Less than that, and the outside mount becomes the safer route.
When Outside Mount Becomes The Only Practical Option
If your window has almost no reveal depth, an outside mount is not just preferred, it is often required to get shutters installed at all.
Expert Tips To Choose The Right Plantation Shutter Mount
A few practical tips I always share with my own clients.
- Always assess window condition and depth before deciding
- Take clear photos of tricky windows for confirmation
- Balance appearance with function and long-term ease of use
- Ask for a professional measurement if you are unsure
- Compare both mounts in person before making a final call
Conclusion
Making your final call comes down to a few simple checks.
Look at your revealed depth, watch for obstructions like handles or tiles, and think about how much light control you actually need.
Deep, clear frames work best with inside mount, while shallow or uneven frames call for outside mount.
I have measured enough windows to know there is no single right answer, only the right fit for your home.
Grab a tape measure, check your frame, and trust what works for your space.

Frequently Asked Questions
Can I Mix Inside Mount And Outside Mount In The Same House
Yes, many homeowners use inside mount in deep frames and outside mount in shallow ones. It is common and looks fine room to room.
Does Outside Mount Cost More Than Inside Mount
Pricing is usually similar since both use the same shutter panels. Installation cost may vary slightly based on your wall and trim setup.
Will Inside Mount Reduce My Window Size
No, the inside mount fits within the existing frame without shrinking the visible glass area. It simply uses the depth that is already there.
Can Outside Mount Be Removed Later
Yes, outside mount shutters can be taken down without major wall damage in most cases. Small screw holes are usually all that remain.
How Do I Know My Frame Depth
Measure from the window glass to the front edge of the wall using a tape measure. Two and a half inches or more suits inside the mount.
