When installing a new HDB door or gate, choosing the right size is essential for a proper fit and smooth installation. In Singapore, HDB and BTO flats typically follow common door dimensions, while condominiums and landed homes may have different requirements. Here’s a simple guide to help you understand the standard door and gate sizes for your home.
Standard Door Sizes Singapore
For HDB and BTO homes in Singapore, the standard single-leaf door size is generally 3 feet by 7 feet. For wider entrances, 4 feet by 7 feet double-leaf doors are also commonly available.
HDB Main Door Size
Single-Leaf Door (3ft x 7ft)
Dimensions: Approximately 91.5cm x 213.5cm (915mm x 2135mm).
Double-Leaf Door (4ft x 7ft)
Dimensions: Approximately 122cm x 213.5cm (1220mm x 2135mm).
Main Door thickness
Main door thickness can vary depending on the door type and construction:
- Non-Fire Rated: Approximately 40–45mm
- Fire-Rated (30 minutes): Typically, 44–45mm
- Fire-Rated (60 minutes): Around 54mm
- Standard Main Door: Around 42mm, although the actual thickness may vary depending on the door and frame specifications.
If you are replacing an existing fire-rated HDB main door, always check the required fire-rating and certification before ordering.
HDB Bedroom Door Size
Room Door Size: 3ft x 7ft (915mm x 2135mm) or approximately 91.5cm x 213.5cm
Bedroom Door Thickness: Approximately 36mm, depending on the door construction and design.
HDB Toilet Door Size
Standard Toilet Door Size: 3ft x 7ft (915mm x 2135mm) or approximately 91.5cm x 213.5cm
Toilet Door Thickness: Around 35mm, depending on the material and door design.
Standard Gate Sizes Singapore
For many HDB homes, the main gate is designed to match the overall entrance opening and door configuration. Common HDB gate sizes include approximately 3ft x 7ft (90 x 210cm) for a single-panel entrance and 4ft x 7ft (120 x 210cm) for a wider double-panel entrance.
However, the actual gate dimensions can vary depending on the existing frame, entrance opening, and installation requirements. Taking accurate measurements before ordering is important.
HDB Gate Sizes
Single-Panel Main Door:
If your main door has a single panel, a 3ft x 7ft gate is commonly suitable.
Double-Panel Main Door:
If your entrance has one larger panel and one smaller panel, a 4ft x 7ft gate is commonly used.
How to Identify the Right Gate Size
Single-Panel Main Door: Usually suitable for a 3ft x 7ft gate.
Double-Panel Main Door (one large, one small): Usually suitable for a 4ft x 7ft gate.
These are common sizes, but they should not be treated as a substitute for measuring your actual entrance opening.
Customizing Your Door & Gate Sizes
Not every HDB, BTO, condominium, or landed property has exactly the same entrance dimensions. If your opening differs from standard measurements, SG Doors offers customisable door and gate solutions, including adjustments to width and height.
Whether you need a wider main gate, a custom-sized HDB door, or a replacement door for an existing opening, choosing the correct measurements helps ensure a better fit and smoother installation. Before purchasing a door or gate, measure the existing opening carefully and check the available frame dimensions. If you are unsure about the required size, SG Doors can help you determine the appropriate dimensions for your home and recommend a suitable solution.
