Laminate Flooring Thickness Guide: 6mm to 14mm Explained
- 2026/10/7
- By Colin Pun, OKBuild Project Manager
Laminate flooring thickness is one of the first specifications buyers notice when comparing products.
A quotation may list:
6mm, 8mm, 10mm, 12mm or even 14mm laminate flooring.
It is easy to assume that the thickest option must always be the best.
That is not necessarily true.
Thickness can affect plank rigidity, floor build-up, walking feel, locking-system design and coordination with doors or adjacent flooring. But it does not automatically determine abrasion resistance, water resistance, core quality or commercial suitability.
A well-specified 8mm laminate floor can be more appropriate for a project than an unsuitable 12mm product.
The correct question is therefore not:
“What is the thickest laminate flooring?”
It is:
“What laminate flooring thickness fits this room, substrate and overall specification?”
This guide compares laminate flooring from 6mm to 14mm and explains what buyers should check before choosing.
For an overview of laminate construction, AC ratings, water resistance and project selection, see OKBuild’s Laminate Flooring Guide.
Laminate Flooring Thickness at a Glance
| Thickness | Main Buying Consideration | |
|---|---|---|
| 6mm | Low floor build-up; complete product specification matters | |
| 7mm | Thin profile; check substrate and locking system carefully | |
| 8mm | Common comparison point with broad residential applications | |
| 9mm | Available in selected products; compare construction rather than number alone | |
| 10mm | Intermediate thickness with increased overall plank build-up | |
| 12mm | Popular comparison point; OKBuild has current 12mm examples | |
| 14mm | Thicker market option; verify whether attached pad is included |
There is no single thickness that is automatically correct for every project.
What Does Laminate Flooring Thickness Mean?
Laminate flooring thickness normally refers to the vertical thickness of the flooring plank.
However, buyers need to check exactly what the quoted number includes.
Some products are sold as:
plank only
while others may be described using:
plank + attached pad = total thickness
For example, one product might have:
10mm laminate plank + 2mm attached pad = 12mm total system thickness.
Another product labeled 12mm may have a 12mm flooring board with no attached pad.
Those two products should not automatically be treated as identical.
When requesting a quotation, ask suppliers to state separately:
| Specification | Example |
|---|---|
| Flooring plank thickness | 10mm |
| Attached pad | 2mm |
| Total flooring product thickness | 12mm |
| Additional underlayment | If required |
This becomes particularly important when coordinating finished floor levels.
Common Laminate Flooring Thicknesses
Laminate flooring is available in several thicknesses, and not every manufacturer offers every size.
The following sections explain the practical differences buyers should consider.
6mm Laminate Flooring
6mm laminate flooring sits at the thinner end of the market.
A thinner profile can be useful where floor build-up needs to remain low, such as:
- Renovation projects
- Existing door-clearance constraints
- Transitions to low-profile flooring
- Areas where raising the finished floor is undesirable
However, 6mm should not automatically be interpreted as low quality.
The complete product still needs to be evaluated for:
- Core construction
- Surface performance
- Locking system
- Subfloor requirements
- Underlayment
- Intended application
Thin flooring generally gives the installer less tolerance for poor substrate conditions.
A correctly prepared subfloor is therefore especially important.
7mm Laminate Flooring
7mm laminate flooring provides another relatively thin option.
It may be considered where a project needs to control finished floor height while still using a floating laminate system.
As with 6mm products, check the locking profile and installation requirements carefully.
The plank thickness should not be used as a substitute for correcting an uneven subfloor.
8mm Laminate Flooring
8mm is one of the more frequently compared laminate flooring thicknesses.
It can provide a practical balance between:
floor build-up + product rigidity + price + installation requirements
for many residential projects.
Potential applications can include:
- Bedrooms
- Living rooms
- Apartments
- Home offices
- Selected light commercial interiors
The actual suitability still depends on the complete specification.
An 8mm product with an appropriate AC rating and properly designed joint system may be more suitable for a given project than a thicker product with an unsuitable specification.
9mm Laminate Flooring
9mm laminate flooring is available but is less frequently used as a headline comparison point than 8mm, 10mm or 12mm.
It should be evaluated in exactly the same way:
thickness + core + surface + locking system + intended use.
If a supplier offers 9mm flooring at a competitive price, do not reject or approve it simply because the number is less familiar.
Compare the actual technical specification.
10mm Laminate Flooring
10mm laminate flooring sits between common 8mm and 12mm options.
The additional thickness can contribute to a more substantial plank profile and increase total floor build-up.
It may suit projects where:
- Floor height allows it
- Greater plank rigidity is preferred
- The selected product specification matches the intended traffic
- The locking system and underlayment are compatible with the substrate
But 10mm should still not be assumed to outperform every 8mm product.
12mm Laminate Flooring
12mm laminate flooring is one of the most searched thickness categories and is widely compared with 8mm and 10mm products.
Its thicker profile may provide:
- A more substantial plank feel
- Greater overall rigidity
- Increased finished floor build-up
- Different locking-profile possibilities
However, none of these automatically proves better:
- AC rating
- Water resistance
- Scratch resistance
- Core quality
- Commercial classification
These specifications must be checked separately.
OKBuild’s current laminate collection includes 12mm plank-format and parquet-format examples.
The plank-style EF and RY ranges include products around:
1219 × 200 × 12mm
while selected Parquet Series products are shown around:
805 × 403 × 12mm.
14mm Laminate Flooring
14mm laminate flooring is also available in the market.
This thicker category deserves one additional check:
Does 14mm refer to the plank itself, or the plank plus attached pad?
For example, a product may use a thinner board plus integrated backing and still be marketed under a larger total thickness.
Always confirm how the manufacturer calculates the measurement.
A 14mm label should therefore not automatically be read as:
14mm wood-fiber core.
8mm vs 10mm vs 12mm Laminate Flooring
These three thicknesses are among the most useful comparison points for buyers.
| Factor | 8mm | 10mm | 12mm |
|---|---|---|---|
| Floor build-up | Lower | Medium | Higher |
| Plank profile | Thinner | Intermediate | Thicker |
| Door / threshold coordination | Usually easier where height is limited | Moderate | Requires more available build-up |
| Subfloor preparation | Important | Important | Important |
| AC rating | Must be checked separately | Must be checked separately | Must be checked separately |
| Water resistance | Product-specific | Product-specific | Product-specific |
| Attached pad | Product-specific | Product-specific | Product-specific |
| Best use | Depends on complete specification | Depends on complete specification | Depends on complete specification |
The key point is:
8mm, 10mm and 12mm describe thickness—not overall quality grades.
8mm vs 10mm Laminate Flooring
The physical difference is 2mm.
That may sound small, but across a complete floor system it can affect:
- Door clearance
- Threshold height
- Transitions
- Skirting
- Stair details
- Adjacent tile or stone
10mm may offer a more substantial plank profile, while 8mm can be useful where total floor build-up is restricted.
The better choice depends on the full product specification.
8mm vs 12mm Laminate Flooring
The difference between 8mm and 12mm is more noticeable.
A 12mm plank can feel more substantial and rigid, but that does not automatically mean it has a stronger surface.
An 8mm product with a suitable abrasion classification may outperform an unsuitable 12mm product in a specific traffic condition.
Do not compare only:
8mm vs 12mm
Compare:
8mm Product A vs 12mm Product B
including all relevant specifications.
10mm vs 12mm Laminate Flooring
10mm and 12mm are relatively close in overall profile.
The practical decision may come down to:
- Product construction
- Available floor height
- Locking system
- Design
- AC rating
- Water-performance requirements
- Price
- Underlayment
- Project documentation
If both products meet the same project requirements, the 2mm difference alone may not justify choosing one over the other.
What Is the Best Thickness for Laminate Flooring?
There is no universal best laminate flooring thickness.
The correct choice depends on the entire floor system.
A useful decision framework is:
| Project Condition | Thickness Consideration |
|---|---|
| Floor height is highly restricted | A thinner product may help |
| Standard residential room | Compare 8mm, 10mm and 12mm products on full specification |
| Greater plank rigidity is preferred | A thicker option may be considered |
| Uneven subfloor | Correct the substrate first; do not rely on thickness alone |
| Commercial project | AC rating, core, joints and documentation matter more than thickness alone |
| Transition to tile or stone | Calculate complete finished floor build-up |
| Attached pad included | Confirm whether the quoted thickness includes the pad |
| Acoustic requirement | Evaluate the complete flooring + underlayment system |
Instead of asking:
“What thickness should I buy?”
ask:
“What thickness works with my substrate, traffic, floor height and product specification?”
Does Thicker Laminate Mean Better Quality?
No.
This is one of the most common laminate flooring misunderstandings.
Thickness describes one physical dimension of the product.
It does not directly tell you:
- How abrasion-resistant the surface is
- How well the joints resist moisture
- How dense the core is
- How strong the click system is
- How suitable the floor is for commercial traffic
- How long the product will last
For example:
12mm does not automatically mean AC5.
Likewise:
8mm does not automatically mean low durability.
If you want to understand these other factors, read OKBuild’s Laminate Flooring Guide.
Laminate Thickness vs AC Rating
Thickness and AC rating describe different things.
Thickness describes the physical depth of the plank.
AC rating primarily relates to abrasion resistance classification.
A buyer should therefore avoid statements such as:
12mm is more wear-resistant than 8mm.
That conclusion cannot be made from thickness alone.
A thinner laminate product may have a higher abrasion classification than a thicker product.
Always compare the exact specification.
Laminate Thickness vs Water Resistance
Thickness also does not automatically determine water resistance.
Water performance can depend on:
- Surface construction
- Joint design
- Edge treatment
- Core formulation
- Installation
- Product testing
A 12mm laminate floor is not automatically more water-resistant than an 8mm laminate floor.
The actual moisture specification needs to be reviewed separately.
How Does Thickness Affect Floor Feel?
Thickness can influence how substantial the plank feels, particularly when comparing otherwise similar products.
A thicker plank may feel more rigid.
However, floor feel is also influenced by:
- Subfloor
- Underlayment
- Locking system
- Plank dimensions
- Installation quality
- Room acoustics
It is therefore difficult to judge floor feel from thickness alone.
Whenever possible, compare physical samples.
Does Thicker Laminate Fix an Uneven Subfloor?
No.
A thicker plank may be more rigid, but laminate flooring should not be used as a substitute for correct substrate preparation.
An out-of-tolerance subfloor can cause problems such as:
- Excessive movement
- Joint stress
- Noise
- Uneven walking feel
- Premature locking-system damage
Before installation, check the product’s subfloor flatness requirements.
Correct major irregularities first.
Laminate Flooring Thickness and Underlayment
Underlayment is another reason buyers should not compare plank thickness in isolation.
A flooring system may include:
Laminate + Attached Pad
or:
Laminate + Separate Underlayment
Underlayment can contribute to:
- Acoustic performance
- Walking feel
- Separation from the substrate
- Moisture management where specified
But adding more underlayment is not automatically better.
Too much compressible material beneath a floating floor can create excessive movement and may affect the click-lock system.
Follow the flooring manufacturer’s approved underlayment requirements.
If a product already has an attached pad, confirm whether additional underlayment is permitted before adding another layer.
Finished Floor Height: Why a Few Millimeters Matter
A difference of 2mm or 4mm can matter when the flooring meets other building components.
Thickness should be coordinated with:
- Doors
- Skirting
- Thresholds
- Stairs
- Cabinets
- Built-in wardrobes
- Tile
- SPC
- LVT
- Stone
- Carpet
For example, if laminate meets porcelain tile, comparing only the two product thicknesses is not enough.
The full build-up may include:
Laminate + Underlayment
versus:
Tile + Adhesive + Leveling System / Substrate Preparation
The final surface levels need to align.
For tile-related planning, see OKBuild’s Tile Thickness Guide.
What Thickness Should You Choose for Different Rooms?
Room type alone should not determine thickness, but it can help define the overall specification.
Bedrooms and Living Rooms
Residential dry areas can use several laminate thicknesses.
The decision should consider:
- Budget
- Floor height
- Subfloor
- Walking feel
- Acoustic requirements
- Product specification
8mm, 10mm and 12mm products may all be viable depending on the exact system.
Apartments
Apartment projects often need additional coordination around:
- Acoustic requirements
- Doors
- Corridors
- Thresholds
- Repeated installation across many units
A thicker product does not automatically provide the required acoustic performance.
The complete floor assembly should be reviewed.
Kitchens
Thickness should not be used as the main indicator of kitchen suitability.
Water resistance, joints, edges and installation requirements are more important for moisture-related decisions.
Offices
For offices, consider:
- Abrasion classification
- Rolling-chair traffic
- Underlayment
- Acoustics
- Subfloor
- Maintenance
Thickness is only one part of the specification.
Hotels
Hotel guestrooms may use laminate flooring where the selected product meets the project requirements.
Coordinate flooring with:
- Guestroom doors
- Bathroom thresholds
- Corridors
- Furniture
- Skirting
- Acoustic requirements
For larger hospitality projects, floor height coordination across repeated rooms can become especially important.
Retail Interiors
Retail projects should prioritize:
- Traffic
- Surface abrasion
- Rolling loads
- Maintenance
- Replacement
- Entrance conditions
Do not choose 12mm or 14mm simply because the floor is commercial.
Commercial suitability needs to be verified separately.
How to Compare Laminate Flooring Thickness Quotations
Consider two quotations:
Supplier A: 12mm Laminate
Supplier B: 10mm Laminate
At first glance, Supplier A may appear to offer a “better” floor.
But the comparison is incomplete.
Before deciding, align:
| Specification | Supplier A | Supplier B |
|---|---|---|
| Plank thickness | Confirm | Confirm |
| Attached pad | Confirm | Confirm |
| Total thickness | Confirm | Confirm |
| Core | Confirm | Confirm |
| AC rating | Confirm | Confirm |
| Water performance | Confirm | Confirm |
| Locking system | Confirm | Confirm |
| Underlayment | Confirm | Confirm |
| Application | Confirm | Confirm |
| Technical documents | Confirm | Confirm |
| Warranty | Confirm | Confirm |
Only after the specifications are aligned does the price comparison become meaningful.
OKBuild 12mm Laminate Flooring Options
OKBuild’s current laminate collection includes several 12mm examples in both plank and decorative parquet formats.
The EF and RY ranges include wood-look planks around:
1219 × 200 × 12mm
with multiple light, medium, grey and dark timber designs.
Selected Parquet Series products use formats around:
805 × 403 × 12mm
to create more decorative geometric flooring patterns.
These products demonstrate how the same 12mm thickness can be used across very different visual formats.
Thickness alone does not define the design or intended use of the floor.
What Should Buyers Check Before Ordering?
Before approving a laminate flooring order, confirm:
| Item | What to Verify |
|---|---|
| Thickness | Plank thickness and total thickness |
| Attached pad | Included or not |
| Dimensions | Length × width |
| Core | Exact core construction |
| AC rating | Required abrasion classification |
| Water performance | Product-specific |
| Locking system | Exact profile |
| Underlayment | Required / attached / separate |
| Subfloor | Flatness and moisture requirements |
| Finished floor height | Coordination with adjacent materials |
| Design | Approved product code |
| Technical documents | Project requirements |
| Packing | m² / carton / pieces |
| Spare stock | Future repair allowance |
For developers and contractors, this should be completed before comparing only the price per square meter.
Frequently Asked Questions
What Is the Most Common Laminate Flooring Thickness?
There is no single thickness used by every manufacturer.
8mm, 10mm and 12mm are common comparison points, while 6mm, 7mm, 9mm and 14mm products can also be found in the market.
Is 12mm Laminate Better Than 8mm?
Not automatically.
12mm is physically thicker, but overall quality also depends on surface performance, core, joints, moisture resistance and installation.
Is 8mm Laminate Flooring Good?
An 8mm product can be suitable for many applications when its full specification matches the project.
Thickness alone cannot determine quality.
Is 6mm Laminate Too Thin?
Not necessarily.
6mm flooring can be used where the selected product and substrate conditions are appropriate.
Pay particular attention to the locking system, subfloor preparation and overall floor assembly.
Is 10mm Laminate Better Than 8mm?
10mm has a thicker plank profile, but that does not automatically make it better.
Compare the complete product specification and project requirements.
Is 14mm Laminate Flooring Available?
Yes, 14mm laminate products are available in the market.
Confirm whether the stated thickness refers to the plank itself or includes attached padding.
Does Thicker Laminate Last Longer?
Thickness alone does not determine service life.
Surface abrasion, core construction, joints, moisture exposure, traffic, installation and maintenance all matter.
Does Thicker Laminate Have a Higher AC Rating?
Not necessarily.
Thickness and AC rating are separate specifications.
Does Laminate Thickness Include Underlayment?
It depends on how the product is specified.
Some listings refer to the flooring board itself, while others may describe total product thickness including attached padding.
Always confirm this before comparing quotations.
What Is the Best Laminate Thickness for a Home?
There is no universal best thickness.
For residential projects, compare the complete specifications of suitable 8mm, 10mm and 12mm products, while also considering floor height, substrate, acoustics and budget.
What Is the Best Laminate Thickness for Commercial Use?
Commercial suitability should not be chosen from thickness alone.
Check abrasion classification, core construction, locking system, water performance, installation requirements and project documentation.
Final Thoughts
Laminate flooring thickness is important, but it should never be treated as a complete quality rating.
The market includes products ranging from relatively thin 6mm options to thicker 12mm and 14mm constructions.
The right choice depends on:
Project → Subfloor → Floor Height → Thickness → Core → AC Rating → Water Performance → Underlayment → Installation
For most buyers, comparing 8mm, 10mm and 12mm is a useful starting point, while 6mm, 7mm, 9mm and 14mm may also make sense for specific products or project conditions.
The most important rule is simple:
Do not pay for additional thickness unless the complete product specification actually benefits your project.
