Singapore Door and Gate Measurements | Standard & Custom Sizes
Door and gate size may look like a small detail, but it matters a lot when you are installing or replacing one in Singapore homes.
There are standard sizes used in most HDB and condo units and landed homes, but it is always safer to measure first.
This guide will give you a clear and simple idea before you make any decision.
Quick Overview: Why Door & Gate Sizes Matter
- Avoid fitting issues during renovation or replacement
- Ensure smooth digital lock installation
- Meet HDB/Condo/fire safety compliance
- Improve long-term durability and home aesthetics
- Enable seamless installation
Standard Door Sizes in Singapore
In Singapore, most homes follow typical industry dimensions for doors, especially for main entrances, bedrooms, and bathrooms.
HDB Main Door Sizes
| Door Type | Size in Feet (Width × Height) | Size in mm (Width × Height) |
| Single-leaf Door | 3×7 ft | 915mm x 2135mm |
| Double-leaf Door | 4×7 ft | 1220mm x 2135mm |
These sizes apply to most HDB and BTO flats, and occasionally condos with standard entryways.
Main Door Thickness (HDB)
| Door Type | Approx. Thickness |
| Main door | 40 – 45 mm |
| Fire-rated main door | Starts From 45 mm |
| Typical HDB Door | ~ may vary with frame |
Note: Fire-rated doors are required for main entrances in some HDBs for safety compliance.
HDB Bedroom Door Size
- Standard Size: 3×7 ft (915mm x 2135mm)
- Thickness: Approximately 36 mm
- Typically used for interior doors and bedroom entryways.
HDB Toilet Door Size

Standard Gate Sizes in Singapore
Your main gate size often matches the dimensions of your main door. Here’s how it works for HDB flats and similar properties:
HDB Gate Sizes
| Gate Type | Size in Feet (W × H) | Size in cm (W × H) |
| Single-panel Gate | 3×7 ft | 90 cm x 210 cm |
| Double-panel Gate | 4×7 ft | 120 cm x 210 cm |
How to Identify Your Gate Size:
- Single Panel Door = Likely 3×7 ft gate
- Double Panel Door (one big + one small leaf) = Likely 4×7 ft gate
Customizing Your Door & Gate Sizes
Not all homes have standard-sized door frames. If your unit has a slightly different layout or if you want something unique, customization is the way to go.
Why Customize?
- Accommodate wider or taller entries
- Ensure digital lock compatibility
- Achieve the design you want without sacrificing function
At Laminate Door Pte Ltd, we offer full customization on:
- Width & height adjustments
- Material & finish selections
- Digital lock-ready door cores
- Matching gates for visual consistency
Before You Buy: Always Measure Accurately
Taking accurate measurements is critical before purchasing or replacing a door or gate. An incorrect size can lead to:
- Poor fit
- Difficult lock installation
- Water or air gaps
- Safety concerns
Not all door frames follow standard sizing — especially in older HDBs or unique layouts. If you want a perfect fit for your digital lock or specific design, custom sizing is your best choice.
If you’re unsure, our Laminate Door Pte Ltd team can measure and assess your entryways to ensure a perfect fit, whether it’s a standard size or a custom request.
