Choosing the right plantation shutter louvre sizes is one of the most important decisions when buying plantation shutters. The width of the louvres affects far more than appearance—it influences how much natural light enters the room, the level of privacy you achieve, your view to the outside, and the overall style of your home.
Whether you’re installing shutters in a bedroom, living room, kitchen or on large sliding doors, selecting the right louvre size ensures your shutters are perfectly proportioned and perform exactly as you expect.
This guide explains the most common plantation shutter louvre sizes available in Australia, their advantages, and how to choose the best option for your home.
What Are Plantation Shutter Louvres?
Louvres are the horizontal blades that sit inside each shutter panel. They rotate open and closed, allowing you to control:
- Natural light
- Privacy
- Ventilation
- Airflow
- Views to the outside
The louvre size refers to the width of each blade.
Wider louvres mean fewer blades across the window, creating a cleaner and more contemporary appearance. Smaller louvres create a more detailed, traditional look.
Choosing the correct plantation shutter louvre size ensures the shutters complement both the size of your windows and the style of your home.
Why Louvre Size Matters
The width of your shutter louvres affects several important factors.
Appearance
Large louvres create bold, clean lines that suit contemporary homes, while smaller louvres offer a more classic appearance.
Natural Light
Larger louvres allow more sunlight into the room when opened.
Privacy
Smaller louvres provide a slightly narrower viewing angle when partially open, offering a little more daytime privacy.
Views
Fewer, wider louvres create a clearer view through the window when opened.
Window Proportion
Choosing a louvre size that matches the scale of the window helps the shutters look balanced rather than oversized or overly busy.
Standard Plantation Shutter Louvre Sizes
Most Australian suppliers offer three standard louvre sizes.
63mm Louvres
63mm is the smallest commonly available option.
Best suited to:
- Heritage homes
- Traditional interiors
- Hamptons-style homes
- Smaller windows
- Bathrooms and hallways
Benefits include:
- Elegant traditional appearance
- Fine architectural detail
- Slightly greater privacy when open
- Ideal proportions for compact windows
Although less common in modern homes, 63mm louvres remain an excellent choice where classic styling is preferred.
89mm Louvres
89mm is the most popular plantation shutter louvre size in Australia.
It offers an excellent balance between classic and contemporary styling.
Ideal for:
- Bedrooms
- Living rooms
- Kitchens
- Bathrooms
- Standard-sized windows
Benefits include:
- Versatile appearance
- Excellent balance of light and privacy
- Suits almost every home style
- Timeless design
For homeowners unsure which louvre size to choose, 89mm is usually the safest recommendation.
114mm Louvres
114mm is the largest standard louvre size and has become increasingly popular in modern Australian homes.
Ideal for:
- Sliding doors
- Large windows
- Floor-to-ceiling glass
- Open-plan living areas
- Contemporary homes
Benefits include:
- Maximum natural light

Large louvres complement large windows by maintaining the correct visual proportions.
Choosing the Right Louvre Size for Your Windows
Small Windows
Windows under approximately one metre wide generally suit:
- 63mm louvres
- 89mm louvres
These sizes maintain visual balance and prevent the shutters from appearing oversized.
Standard Windows
Most bedrooms, kitchens and living rooms feature standard-sized windows.
89mm remains the most versatile option, although 114mm can work beautifully in contemporary homes.
Large Windows and Sliding Doors
Wide windows and sliding doors usually look best with 114mm louvres.
The wider blades suit the scale of large glass panels while maximising natural light and outdoor views.
How Louvre Size Affects Light and Privacy
Many homeowners assume all shutter sizes perform the same.
While fully closed shutters block similar amounts of light, the difference becomes noticeable when the louvres are open.
63mm Louvres
- Maximum daytime privacy
- Less natural light
- Smaller viewing angle
89mm Louvres
- Excellent balance
- Comfortable privacy
- Good natural light
- Versatile performance
114mm Louvres
- Maximum natural light
- Widest outdoor views
- Most open appearance
- Slightly less privacy when partially open
The right choice depends on how you use each room and the balance you want between privacy and natural light.
Matching Louvre Sizes to Your Home Style

- 63mm
- 89mm
These sizes complement decorative architectural features and classic interiors.

Can You Mix Different Louvre Sizes?
Yes.
Many homeowners use different plantation shutter louvre sizes throughout the home to suit each room.
A common combination includes:
- 114mm for living rooms and sliding doors
- 89mm for bedrooms and kitchens
- 63mm for bathrooms, laundries and smaller windows
Because each room is viewed independently, using different louvre sizes creates a practical solution without appearing inconsistent.
