 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.
