Standard Door and Gate Sizes in Singapore: A Guide for HDB & All Homes

 

When installing a new door or gate in your home, selecting the correct size is crucial to ensure a perfect fit, seamless functionality, and long-term durability. In Singapore, HDB flats, condominiums, and landed properties often follow different standard dimensions. This guide will help you understand the most common door and gate sizes across residential properties, so you can confidently choose.

 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

Single-leaf Door	3x7 ft	915mm x 2135mm
Double-leaf Door	4x7 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	Typically 40 – 45 mm

 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

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

 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.
