When choosing vinyl flooring, two of the most commonly discussed features are thickness and wear layer. Homeowners often wonder: “Is 8mm better than 5mm?” Or “Should I care more about the wear layer?” This article helps you understand how these measurements affect your floor’s performance, feel, and longevity—and which one matters most for your space.
1. What Does Thickness Mean in Vinyl Flooring?
The overall thickness of vinyl flooring (measured in millimeters, like 5mm or 8mm) refers to the full depth of the plank, including the wear layer and any attached underlayment.
5mm Vinyl Flooring: Thin and flexible. Best suited for light residential spaces or where floor height needs to be minimized. Often used in condos, bedrooms, or small apartments.
8mm Vinyl Flooring: Thicker, more rigid, and more stable underfoot. Offers better sound insulation, greater comfort, and can help smooth out minor imperfections in the subfloor. Preferred in high-traffic homes or basements.

Takeaway: Thicker floors offer a more premium, cushioned feel and better noise control, especially if they come with an attached pad.
2. What Is a Wear Layer—and Why Does It Matter More?
The wear layer, measured in MIL (1 MIL = 1/1000 of an inch), is the top protective layer that sits over the printed vinyl design. It protects the floor from daily wear like scratches, dents, water, stains, and fading.
6–12 MIL: Entry-level durability. Suitable for bedrooms or light foot traffic.
12–20 MIL: Ideal for active homes with kids or pets. This is a great middle ground.
20+ MIL: Best for heavy residential use or commercial spaces. Longest lifespan and best resistance to damage.

Takeaway: The wear layer is the real shield protecting your investment. Even a thick plank without a strong wear layer can wear out quickly in busy households.
3. Which One Should You Prioritize—Thickness or Wear Layer?
If you're torn between a 5mm plank with a 20 MIL wear layer and an 8mm plank with only a 12 MIL wear layer, always lean toward the higher wear layer—especially for durability and resistance to daily wear and tear.
However, if comfort underfoot, sound reduction, or installing over an uneven subfloor is a top concern, choosing an 8mm product with a quality wear layer is ideal.
4. Summary: What’s Best for Your Project?
Need | Recommended Option |
Light traffic / spare rooms | 5mm thickness with 12 MIL wear layer |
Busy home with kids/pets | 6mm+ thickness with 20 MIL wear layer |
High-end feel and comfort | 8mm with attached underlayment + 20 MIL |
Rental / commercial property | 20–28 MIL wear layer, 6–8mm thickness |
Vinyl plank flooring has revolutionized home design by offering style, water resistance, and ease of maintenance. But not all vinyl is created equal. A high-quality wear layer is your first line of defense, while thicker planks add comfort and visual depth.
Tip: Always ask for specs before buying. And don’t hesitate to consult a flooring professional to match the product to your lifestyle and space.
