How Thick Should Vinyl Flooring Be? A Complete Guide

When getting Vinyl Flooring, we always get asked how thick it should be. Don't worry, in this article I will give you a complete guide to vinyl flooring thickness. Vinyl is an inexpensive, water-resistant, and easy-to-maintain material with a long lifetime. Still, deciding how thick the flooring should be can be challenging.

For less-visited areas like the bedroom and storage room, choose thinner vinyl flooring; for high-traffic areas like the kitchen and living room, choose thick vinyl flooring. 

Understanding Vinyl Flooring's Two "Thicknesses"

When a salesperson talks about thickness, they could be referring to one of two things. Confusing them is the most common mistake buyers make. Learn about Wood Vinyl Flooring vs Hardwood: Pros, Cons & Cost by clicking the link.

The Wear Layer: The Most Important Metric for Durability

Think of the wear layer as the screen protector for your floor. It's the topmost, transparent coating that protects the printed design from scratches, scuffs, stains, and fading. For 90% of homeowners, the thickness of the wear layer is more critical than the plank's total thickness.

This layer is measured in millimeters (mm) and directly determines how well your floor will withstand kids, pets, dropped items, and shifting furniture.

Total Plank Thickness: The Metric for Stability and Feel

This is the measurement of the entire plank from top to bottom, including the core and any attached underlayment. It's also measured in millimeters (mm).

The total thickness determines the plank's rigidity, how "solid" it feels underfoot, its ability to hide minor imperfections in your subfloor, and how well it insulates sound.

Recommended Vinyl Flooring Thickness for Singapore Homes

Here are the standard measurements you'll find, along with what they're good for in a typical Singaporean home.

For the Wear Layer (The Durability Factor)

• 0.2mm - 0.3mm: 

Suitable for low-traffic areas, such as bedrooms or studies.

• 0.3mm - 0.5mm:

This is the sweet spot for standard residential use. It's ideal for living rooms, kitchens, hallways, and homes with children or pets. Most quality vinyl flooring sold for HDB and condo projects falls in this range.

• 0.5mm and above:

This is considered commercial-grade. It's highly durable and great for home offices with rolling chairs or very high-traffic areas.

For Total Plank Thickness (The Stability & Comfort Factor)

• 4mm - 5mm: A common and perfectly effective standard for residential use. This thickness is budget-friendly but works best when installed over a very smooth and level subfloor.

• 5.5mm - 6mm: This is the recommended sweet spot for most HDB and condo projects. It offers an excellent balance of durability, comfort underfoot, and sound insulation.

Thick vs. Thin: A Quick Comparison

Thinner Vinyl (e.g., 3.5mm - 4.5mm)

• Pros: More affordable, easier to cut and install, fewer issues with clearing door bottoms.

• Cons: Less sound insulation, less comfortable underfoot, and more likely to show subfloor imperfections.

Thicker Vinyl (e.g., 5.5mm - 8mm)

• Pros: Better sound absorption, feels more solid and comfortable, excellent at hiding minor subfloor flaws.

• Cons: Higher cost, may require trimming doors, and slightly more complex installation.

Conclusion

The ideal vinyl flooring for Singapore homes emphasises a robust wear layer, a stable SPC core, and a balanced overall thickness. Aim for 0.3mm–0.5mm on the wear layer to ensure long-term durability. Choose SPC for maximum stability in our humid climate. A total thickness of 5mm–6mm offers the best comfort, sound insulation, and subfloor coverage. This combination delivers a durable, quiet, and reliable flooring solution for everyday Singapore living. Get the ultimate guide to wooden vinyl floor by clicking the link.

Frequently Asked Questions (FAQs)

Is 8mm vinyl flooring always better than 5mm? 

Not necessarily. A 5mm plank with a 0.5mm wear layer is far more durable and a better choice than an 8mm plank with a 0.2mm wear layer. Durability comes from the wear layer, while thickness provides comfort and stability, each has its own pros and cons.

What is a "mil"? I see it in some marketing. 

"Mil" is a US measurement, not to be confused with millimetres (mm). 1 mil equals one-thousandth of an inch. It's used to measure wear layers. The conversion is roughly:

• 12 mil ≈ 0.3mm (Good)

• 20 mil ≈ 0.5mm (Excellent)

Does the total thickness include the built-in underlayment? 

Yes. Almost all modern SPC vinyl planks come with a pre-attached underlayment (pad). A 6mm plank, for example, typically has a 5mm SPC core and a 1mm attached underlayment.

Will thick vinyl fix a very uneven floor? 

No. Thick vinyl (5.5mm+) can hide minor imperfections, but it cannot fix a truly uneven subfloor. If your floor has significant dips or is sloped, it must be professionally levelled with a cement screed before any vinyl installation.
