Who this guide is for
- Homeowners adding shutters to improve curb appeal
- People whose existing shutters look too small for the windows
- Renovators choosing between decorative and operable shutters
- Anyone briefing a carpenter or installer on shutter detailing
Decorative versus operable
Decorative shutters are fixed in place and chosen purely for looks, while operable shutters swing on hinges and can actually close over the glass. Operable shutters need correct sizing, working hardware, a holdback and clearance to swing, so they are a more involved decision. Decide which you want before anything else, because it changes sizing and mounting.
Sizing to the window
The single most important rule is that a pair of shutters should look like it could cover the window: roughly the window's height, and together about half its width each. Shutters that are obviously too narrow to ever meet read as stuck-on decoration. Measure each opening rather than assuming all windows match.
- Height roughly matches the window opening
- Each leaf is about half the window width
- Allow for windows of different sizes on the same facade
- Keep reveal and trim clearances consistent
Style, profile and material
Shutter style, louvered, paneled or board-and-batten, should suit the house's character and the window type. The profile and material affect both the look and how the shutter weathers. Coordinate the style across the whole elevation so the facade reads consistently.
Mounting, wind and fixings
How a shutter attaches matters for both looks and safety: decorative shutters still load the wall and can become hazards in high wind if poorly fixed, and operable shutters need hinges and holdbacks rated for the conditions. Plan the fixing and any wind exposure deliberately. This is where professional input earns its place.
Color, coordination and getting help
Shutter color is part of the overall exterior scheme and usually relates to the trim or accent role rather than fighting the field color. A carpenter or installer should confirm fixings, and in exposed or storm-prone locations the wind performance of any shutter should be reviewed by a qualified professional. Requirements vary by location and project.
Shutter planning checklist
- 1Decide whether you want decorative or operable shutters
- 2Measure each window opening individually
- 3Size each pair to look like it could close over the glass
- 4Choose a shutter style that suits the house character
- 5Coordinate shutter color with the exterior scheme
- 6Plan the mounting method and any wind exposure
- 7For operable shutters, plan hinges, holdbacks and swing clearance
- 8Have a professional confirm fixings and wind performance
Common mistakes to avoid
- Fitting shutters too narrow to ever cover the window
- Using one shutter size for windows of different widths
- Treating decorative shutters as if fixing and wind don't matter
- Choosing a style that clashes with the house character
- Picking a color that fights the field instead of the trim
- Specifying operable shutters without planning hardware and clearance
When to involve a professional
- Have a carpenter or installer confirm wall fixings for the shutters
- Review wind performance with a qualified professional in exposed areas
- For operable shutters, confirm hinge and holdback suitability
- Treat poorly fixed shutters as a potential wind hazard, not just cosmetic
- Requirements vary by location and project; verify with your professionals
Frequently asked questions
Questions readers ask about this topic
How big should exterior shutters be?
Each pair should look as though it could close over the window, so roughly the window's height and together covering its width, about half the width each leaf. Shutters too narrow to ever meet read as stuck-on decoration.
What's the difference between decorative and operable shutters?
Decorative shutters are fixed and purely visual, while operable shutters swing on hinges and can actually close. Operable shutters need correct sizing, working hardware, holdbacks and swing clearance, so they are a more involved planning decision.
Do decorative shutters need professional fixing?
They still load the wall and can become hazards in high wind if poorly attached, so the fixing matters even when they never move. A carpenter or installer should confirm the fixings, especially in exposed or storm-prone locations.
What color should shutters be?
Shutter color is part of the overall exterior scheme and usually relates to the trim or accent role rather than fighting the main field color. Coordinating it across the whole elevation keeps the facade looking consistent.
