Australian Barn Door Size Calculator
Here’s a comprehensive table for Australian Standard Barn Door Sizing, covering essential dimensions, components, and guidelines for proper installation and functionality.
| Measurement Type | Standard Dimension/Formula | Description & Use |
|---|---|---|
| Door Width | Opening width × 1.05 | Door width should be 5% wider than the doorway to ensure full coverage and prevent light gaps. |
| Door Height | Opening height × 1.05 | Door height should be 5% taller than the doorway for complete top-to-bottom coverage, including trim. |
| Track Length | Door width × 2 | Track length should be double the door width to allow for full sliding range. |
| Door Thickness | 35–45 mm (standard) | Australian barn doors typically range from 35 mm to 45 mm for stability and durability. |
| Clearance from Floor | 10 mm | Allows the door to slide smoothly without contacting the floor, important for both carpeted and tiled areas. |
| Wall Space Needed | Door width × 2 | Wall space should equal twice the door width for a full open position without obstruction. |
| Ceiling Clearance | 150–200 mm above door height | Provides enough space for the track system, mounts, and adjustments. |
| Distance from Wall | 20 mm (minimum) | Minimum gap to ensure the door clears baseboards or skirting boards for smooth sliding. |
| Overlap for Double Doors | 20 mm per door | Each door should overlap slightly in the middle to avoid gaps when closed, improving privacy and sound control. |
| Handle Height | 900–1050 mm from the floor | Comfortable reach height for most users, similar to doorknob height on standard doors. |
| Hardware Weight Capacity | 40–90 kg (based on door weight) | Ensure track and hardware can support the specific door weight for safety and durability. |
| Stud Requirement for Track | Wall studs or structural header required | Tracks should be mounted into wall studs or a solid backing for stability and safety. |
| Guide Bracket Space | 10 mm from floor, centered under door | Floor guides prevent door from swinging and should be installed with 10 mm clearance from the floor. |
| Latch or Lock Options | Optional, depending on hardware | Locks can be added for privacy, but check compatibility with barn door style and handle type. |
Key Considerations for Australian Standard Barn Door Sizes
- Door Width and Height: Adding 5% to both width and height ensures full coverage, reducing light gaps and drafts. For example, if the doorway is 1000 mm wide, the recommended door width would be 1050 mm.
- Track Length and Wall Space: The track length should be twice the door width to allow the door to slide fully open and close. Ensure enough wall space on one side to allow for this.
- Clearance and Ceiling Space: Maintain a 10 mm floor clearance to prevent the door from scraping the floor, and ensure at least 150–200 mm of ceiling clearance for track installation.
- Distance from Wall: A minimum gap of 20 mm from the wall allows the door to slide smoothly without hitting wall features like skirting boards.
- Double Door Overlap: For double doors, allow at least 20 mm of overlap to ensure that both doors close completely, improving privacy and reducing sound transmission.
- Weight Capacity and Stud Support: Use hardware that can support the door’s weight (most standard hardware supports up to 90 kg). Tracks should be secured to wall studs or a structural header for safe operation.
