A Clear Guide to Flooring Thickness: 8mm vs 12mm
Choosing the right flooring thickness is one of the most important & most misunderstood parts of selecting a new floor.
Thickness affects durability, comfort, sound, moisture resistance, and how the floor performs over time. This guide explains the difference between 8mm and 12mm flooring, so you can choose the option that suits your home.
What Flooring Thickness Really Means
Flooring thickness refers to the depth of each plank, usually measured in millimetres.
At Wood Floor Store, our ranges focus on 8mm and 12mm, as these offer the best balance of performance, durability and value for modern homes.
Thicker flooring does not automatically mean “better”, but it does behave differently.
What 8mm Flooring Offers
Our 8mm flooring is typically AC4-rated and water-resistant, making it a reliable choice for most living spaces.
It provides:
- Strong durability for everyday residential use
- Resistance to everyday spills and routine cleaning
- A cost-effective solution without compromising appearance
8mm water-resistant flooring is ideal where moisture exposure is limited and consistent performance is required.

What 12mm Flooring Adds
Our 12mm flooring is most often AC5-rated (commercial grade), meaning it is designed for higher traffic and heavier wear. Many, though not all, 12mm floors are also fully waterproof, offering an added layer of protection.
12mm flooring provides:
- Increased durability in busy households
- A more solid, stable feel underfoot
- Better sound absorption
- Strong performance in high-traffic zones
- Waterproof options suitable for moisture-prone areas
