How to Choose the Right Laminate Thickness for Your Home

Walk into a flooring store and you'll quickly notice that laminate planks come in a range of thicknesses. Most options run from 6mm on the thin end to 12mm or more on the thicker end. Then there's the AC rating system on top of that. For someone who just wants a good floor, all these numbers can feel confusing fast.

Here's a clear explanation of what these specifications actually mean, and how to match them to the right room in your home.

Why Thickness Matters

Laminate thickness affects how the floor feels underfoot, how well it handles subfloor imperfections, how much sound it absorbs, and how durable it feels over time. A thicker plank generally performs better across all of these areas, but the right choice depends on the room you're installing it in and your budget.

Thickness is measured in millimeters and refers to the full plank from the bottom backing layer to the top wear surface.

The Thickness Options, Explained

6mm to 7mm: Thin and Budget-Friendly

This is the entry-level range. Six and seven millimeter laminate is lighter and less expensive, but it has real limitations.

• It magnifies subfloor imperfections more than thicker options

• It feels slightly hollow underfoot, especially without a quality underlayment

• It provides minimal sound dampening

• It's best suited for low-traffic areas like guest bedrooms or storage spaces

If you're working with a tight budget and the room sees light use, 6mm to 7mm laminate can work. But in most living areas, it will feel noticeably thinner than what most homeowners are hoping for.

8mm: A Step Up

Eight millimeter laminate is a solid middle-ground option. It handles subfloor variation better than thinner planks and starts to feel more substantial underfoot. It works well in:

• Standard bedrooms

• Low-to-moderate traffic areas

• Rooms over a wood subfloor in good condition

10mm: The Sweet Spot for Most Homes

Ten millimeter laminate is where the real improvement in quality starts to show. It's thick enough to feel solid and comfortable, absorbs subfloor imperfections well, and provides noticeably better sound insulation than thinner options.

For most Asheville homeowners, 10mm laminate is the right call for living rooms, hallways, and bedrooms. It handles everyday family life without flexing or feeling hollow, and it's widely available from the quality brands we carry like Mohawk, Mannington, and LW Flooring.

12mm and Above: Premium Feel

Twelve millimeter laminate is as close as you get to the feel of real hardwood underfoot. It absorbs sound exceptionally well, feels dense and stable, and handles subfloor inconsistencies with the most forgiveness of any option in the laminate category.

It's the right choice for:

• Open-plan living spaces

• Rooms over concrete subfloors where a solid feel is important

• Homeowners who want the most realistic wood-like experience

• High-traffic areas in active households

The trade-off is price and availability. Not every style comes in 12mm, and you'll pay more per square foot. But for the right room and the right homeowner, it's worth it.

What Is the AC Rating System?

Thickness tells you how the floor feels. The AC rating tells you how well the floor's wear layer holds up to use. AC stands for Abrasion Class, and it's a standardized European rating system used by most laminate manufacturers.

Here's what each rating means in practical terms:

AC Rating	Intended Use	Best For
AC1	Light residential	Bedrooms, low-traffic rooms
AC2	General residential	Bedrooms, living rooms, moderate traffic
AC3	Heavy residential / Light commercial	Most rooms in active homes
AC4	Heavy residential / Commercial	High-traffic areas, homes with kids and pets
AC5	Commercial heavy duty	Commercial spaces, extremely active households

For most Asheville homeowners, AC3 or AC4 is the right target. AC3 handles everyday family life with ease. AC4 is the better choice if you have pets, kids, or a household that sees a lot of foot traffic.

How Thickness Interacts With Underlayment

Underlayment is the thin cushioning layer installed between the subfloor and the laminate planks. It affects how the finished floor feels and sounds almost as much as the plank thickness itself.

Some laminate products come with underlayment pre-attached to the back of each plank. Others require a separate sheet underlayment. Thicker planks often don't need as heavy an underlayment because the plank itself provides more cushion and rigidity.

If your subfloor has minor imperfections, a combination of a thicker plank and a quality foam underlayment will do the most to mask those issues and give you a comfortable, quiet floor.

Matching Thickness to Room Type

Here's a practical reference for matching thickness to common rooms in your home:

Bedrooms: 8mm to 10mm is fine for most bedrooms. If the room is over a concrete slab, lean toward 10mm for added comfort.

Living Rooms and Family Rooms: 10mm to 12mm. These are the rooms that get the most daily use, so a thicker, higher AC-rated plank is worth the investment.

Hallways: At least 10mm, and consider AC4. Hallways see concentrated foot traffic in a narrow path, which puts more wear on a floor than open rooms do.

Basements: 10mm to 12mm with a moisture-barrier underlayment. Basements present more moisture risk, and a thicker, denser plank handles those conditions better. Also worth comparing LVP flooring for basement applications, since LVP is fully waterproof.

Home Offices: 10mm is sufficient. If you use a rolling chair, make sure your desk chair mat is appropriate for hard flooring surfaces.

What About Wall Laminate?

If you're planning to use laminate on an accent wall or as wainscoting, thickness is less critical than it is for floors. Six to eight millimeter laminate works fine for wall applications because it doesn't carry any foot traffic load. The more important considerations for wall installation are the surface texture, the look you're going for, and proper installation technique to ensure the planks stay flat and secure.

Our team handles both wall and floor laminate installation. If you're interested in combining a feature wall with new laminate floors, we can walk you through the options during your consultation.

Frequently Asked Questions

Is thicker laminate always better?

Thicker laminate generally performs better, but the improvement levels off after 12mm. The biggest jumps in quality and feel happen going from 6mm to 10mm. Going from 10mm to 12mm gives you a noticeable improvement, but 12mm to 15mm is marginal for most homeowners.

Does a higher AC rating mean better thickness?

No. AC rating and thickness are separate specifications. A 6mm plank can have an AC4 rating, and a 12mm plank can have an AC2 rating. You want to match both specs to the room — a higher AC rating for durability, and appropriate thickness for comfort and subfloor forgiveness.

Does laminate thickness affect installation?

Slightly. Thicker planks are heavier and slightly more rigid. They also affect how transition strips and door clearances work. Our installers account for thickness when planning the job.

How does laminate thickness compare to LVP?

LVP typically runs between 4mm and 8mm but feels different than laminate of the same thickness because of its denser vinyl core. A 6mm LVP often feels as solid as an 8mm laminate. Read our laminate vs. LVP comparison for a full breakdown of how the two products differ.
