Vinyl Flooring Thickness Explained: Choosing Between 2mm, 4mm, 4.2mm and 5mm

When shopping for vinyl flooring, most people start by thinking about colour, finish, or style. But one detail that’s often overlooked — and just as important — is thickness. The thickness of your flooring not only affects how it feels underfoot but also plays a big role in durability, stability, and where it’s best installed.

In this guide, we’ll break down everything you need to know about 2mm, 4mm, 4.2mm, and 5mm vinyl flooring so you can make the right choice for your home.

Why Thickness Matters

Thickness in vinyl flooring is measured in millimetres and refers to the depth of each plank or tile. While it might seem like a small difference, that extra millimetre or two can make a big impact.

Here’s why it matters:

• Durability – Thicker flooring can withstand heavier foot traffic.
  
  

• Comfort – A thicker plank usually feels softer and warmer.
  
  

• Sound – Thicker floors help reduce noise transfer between rooms.
  
  

• Subfloor imperfections – Thicker options are better at covering uneven surfaces.
