How Thick is Vinyl Plank Flooring?

Vinyl plank flooring has become a popular choice for homeowners due to its durability, water-resistance, and ease of installation. Thickness plays a critical role as it impacts the performance, feel, and lifespan of the flooring.

Typically, vinyl plank flooring can range from 2mm to 8mm thick. Thicker planks offer improved insulation, noise reduction, and a more comfortable underfoot feel. When choosing the right thickness for your needs, it’s important to consider factors like foot traffic and the room’s purpose.

Vinyl Plank Flooring Thickness

When evaluating vinyl plank flooring thickness, it is essential to consider the three key layers that contribute to its overall thickness and durability. These layers are the wear layer, core layer, and backing layer. Let’s delve deeper into each of these layers and their respective thicknesses.

Wear Layer

The wear layer is the topmost layer of vinyl plank flooring, responsible for protecting the floor’s surface from wear and tear. This layer determines the flooring’s durability and resistance to scratches, stains, and fading. Wear layer thickness can range from 6 to 40 mil (1 mil = 0.001 inch). Some typical wear layer thicknesses are:

  • Light residential use: 6-12 mil
  • Medium residential use: 12-20 mil
  • Heavy residential & commercial use: 20-40 mil

Core Layer

The core layer is the middle section of vinyl plank flooring, giving structural stability and strength. This layer is often composed of PVC, limestone powder, and plasticizers. Core layer thickness can vary from 2 mm to 7 mm, and it mainly impacts the overall thickness of the plank. Thicker core layers generally provide better sound absorption and dent resistance.

Backing Layer

The backing layer is the bottom layer of vinyl plank flooring, providing cushion and adhering the planks to the subfloor. This layer may be composed of materials like cork or foam, offering added insulation and noise reduction. Backing layer thickness typically ranges from 1 mm to 2 mm.

In summary, when considering the thickness of vinyl plank flooring, the wear, core, and backing layers contribute to its overall thickness, durability, and performance. Understanding these layers and their thicknesses helps in choosing the right flooring for your needs.

Factors to Consider When Choosing Thickness

Several factors can influence the preference for a particular thickness in vinyl plank flooring. Here, we discuss the main factors: Foot Traffic, Subfloor Type, Budget, and Room Function.

Foot Traffic

Foot traffic determines the level of wear and tear on the floors. Rooms with more foot traffic, like living rooms and kitchens, require thicker floors to withstand the impact. A general guideline is:

  • 2mm – 2.5mm: Light foot traffic areas
  • 3mm – 5mm: Moderate foot traffic areas
  • 5mm and above: High foot traffic areas

Subfloor Type

The type of subfloor you have plays a significant role in determining the thickness of vinyl plank flooring needed. A smooth and even subfloor can accommodate thinner planks, while uneven or rough subfloors require thicker planks for better stability. Consider the following:

  • 2mm – 3mm: Smooth and even subfloors
  • 4mm – 5mm: Slightly uneven subfloors
  • 6mm and above: Rough and uneven subfloors


The cost of vinyl plank flooring can differ depending on the thickness. Thicker planks are generally more expensive due to their added durability and materials used. A budget breakdown based on thickness is:

  • 2mm – 3mm: $1 – $3
  • 4mm – 5mm: $2 – $4
  • 6mm and above: $3 – $5+

Room Function

Lastly, consider the function of the room when selecting the thickness of vinyl plank flooring. For example, bathrooms and basements may require thicker planks to withstand moisture and dampness. In contrast, bedrooms and closets may need less robust planks because of comparatively less foot traffic and moisture exposure.
