Choosing the Right Louvre Size

1. Consider the Window Size:

  • Small Windows: For smaller windows, opt for smaller louvres like 63mm. They provide a balanced look and allow for precise control of light and privacy.
  • Medium Windows: Medium-sized windows work well with 76mm louvres. They offer a versatile option suitable for various window dimensions.
  • Large Windows: Larger louvres 89mm are ideal for expansive windows. They create a bold, dramatic look, making them perfect for spacious rooms with high ceilings.

2. Room Proportions and Ceiling Height:

  • Low Ceilings: If your room has low ceilings, larger louvres can create an illusion of height and make the space feel more expansive.
  • High Ceilings: In rooms with high ceilings, you can opt for any louvre size depending on your preference. Larger louvres enhance the grandeur, while smaller ones offer a classic appeal.

3. Style Preferences:

  • Traditional Look: Smaller louvres (63mm) are reminiscent of traditional shutters, adding a timeless charm to your home.
  • Modern Aesthetics: Larger louvres (76mm, 89mm) provide a contemporary, bold appearance, complementing modern interior designs.

4. View and Light Control:

  • Scenic Views: If your window overlooks a beautiful landscape, consider shutters with larger louvres. They provide unobstructed views when opened and allow more natural light to enter the room.
  • Privacy Needs: Smaller louvres offer enhanced privacy, especially for street-facing windows. Tilt them closed to prevent prying eyes while still allowing light to filter through.

5. Maintenance and Cleaning:

  • Ease of Cleaning: Larger louvres are easier to clean due to their size, making them a practical choice for homeowners who prefer low-maintenance window treatments.
