What Thickness Hybrid Flooring Should You Buy? 7mm vs 9mm
When comparing hybrid flooring, thickness is one of the first specifications most buyers notice.
You may see 6mm, 7mm, 8mm, 9mm or thicker hybrid flooring, with thicker products often positioned as the more premium option.
That creates an obvious question:
Is 9mm hybrid flooring actually better than 7mm — and is it worth paying extra?
Not necessarily.
Thickness can affect the construction, underfoot feel, floor height and potentially acoustic performance of a hybrid floor. But it does not automatically determine scratch resistance, durability or overall quality.
A well-made 7mm hybrid floor can easily be a better choice than a lower-quality 9mm product.
The key is understanding where those extra millimetres are going.
This guide compares 7mm and 9mm hybrid flooring and explains the other specifications Melbourne homeowners should check before buying.
Quick Answer: For many residential applications, a quality 7mm hybrid floor is already sufficient. A 9mm product may offer a more substantial construction, thicker core or improved acoustic backing — but only if the additional thickness contributes to a genuinely better product.
Don’t choose hybrid flooring by thickness alone.
What Does Hybrid Flooring Thickness Actually Measure?
Hybrid flooring is made from several layers rather than one solid piece of material.
A typical plank may include:
- Protective surface and wear layer
- Decorative timber-look layer
- Rigid SPC or composite core
- Attached acoustic underlay
The advertised thickness often refers to the total thickness of the plank, including attached underlay.
For example, two products both advertised as 7mm may have different core and underlay constructions.
One might have a thicker rigid core with a thinner backing, while another achieves the same total thickness with a different combination.
Don’t ask only “How thick is it?”
Ask: “What is the core thickness, what is the wear layer, and does the advertised thickness include the attached underlay?”
7mm vs 9mm Hybrid Flooring: Quick Comparison
| Feature | 7mm Hybrid Flooring | 9mm Hybrid Flooring |
|---|---|---|
| Residential Use | Excellent on quality products | Excellent |
| Underfoot Feel | Solid when correctly installed | May feel more substantial |
| Core Construction | Product-dependent | May have a thicker core |
| Scratch Resistance | Depends on surface construction | Depends on surface construction |
| Wear Resistance | Depends largely on wear layer | Depends largely on wear layer |
| Acoustics | Can be very good | May offer improvement depending on backing |
| Subfloor Preparation | Essential | Essential |
| Finished Floor Height | Lower | 2mm higher |
| Price | Generally lower | Generally higher |
| Best For | Most residential projects | Premium construction where benefits justify cost |
A 9mm floor is not automatically more durable or scratch-resistant than a 7mm floor. Overall construction matters more than the headline thickness.
Is 7mm Hybrid Flooring Thick Enough?
For many residential projects, yes.
A quality 7mm hybrid floor can be suitable for:
- Living rooms
- Kitchens
- Dining areas
- Bedrooms
- Hallways
- Apartments
- Family homes
- Investment properties
What matters is the quality of the complete product.
A well-designed 7mm floor with a suitable wear layer, dense rigid core, reliable locking system and good acoustic backing can provide excellent residential performance.
For most homes, 7mm should not be considered “too thin” simply because a 9mm option exists. Product quality and correct installation matter far more than an extra 2mm on the specification sheet.
When Is 9mm Hybrid Flooring Worth Considering?
A 9mm product can be worth paying more for when the additional thickness is part of a better overall construction.
Depending on the product, this may include:
- A thicker or more substantial rigid core
- Improved locking-joint geometry
- Higher-quality acoustic backing
- Better acoustic performance
- More substantial feel underfoot
- Higher overall product specification
The important question isn’t simply whether the board is thicker.
It’s:
What does the extra 2mm actually give you?
If the answer is a better core, better backing, better acoustics or stronger overall construction, the upgrade may make sense.
If the main difference is simply the number printed on the box, it may not.
Thickness vs Wear Layer: Don’t Confuse the Two
This is one of the most important distinctions when buying hybrid flooring.
Total plank thickness and wear-layer thickness measure completely different things.
Total Plank Thickness
This refers to the overall thickness of the flooring product and may include the attached underlay.
It can influence:
- Overall construction
- Underfoot feel
- Finished floor height
- Locking-joint design
- Acoustic characteristics
Wear-Layer Thickness
The wear layer is the transparent protective layer above the decorative timber design.
It helps protect the appearance of the floor from everyday wear.
Common specifications you may encounter include 0.3mm and 0.5mm, although products vary.
A 9mm floor does not automatically have a thicker wear layer than a 7mm floor.
You could have a 7mm floor with a 0.5mm wear layer and a 9mm floor with a 0.3mm wear layer.
Is a 0.5mm Wear Layer Better Than 0.3mm?
All else being equal, a thicker wear layer provides more protective material above the decorative surface.
For busy residential areas, a 0.5mm wear layer can be an attractive specification, particularly in homes with:
- Children
- Pets
- High foot traffic
- Open-plan living
- Dining areas
- Frequent entertaining
However, wear-layer thickness is still only one part of the product.
Surface coating, manufacturing quality and the construction of the flooring also influence real-world performance.
When comparing hybrid flooring, ask for at least these two numbers:
Total thickness: ____ mm
Wear layer: ____ mmThey tell you two different things.
Does 9mm Hybrid Flooring Last Longer Than 7mm?
Not necessarily.
Consider these two hypothetical products:
| Specification | Product A | Product B |
|---|---|---|
| Total Thickness | 7mm | 9mm |
| Wear Layer | 0.5mm | 0.3mm |
| Core Quality | High | Basic |
| Locking System | High Quality | Basic |
| Acoustic Backing | Quality Backing | Standard Backing |
You cannot conclude that Product B will last longer simply because it is 2mm thicker.
Product A may offer better surface protection, better joint performance or better overall construction.
Thickness tells you how thick the floor is. It does not tell you how good the floor is.
Does Thicker Hybrid Flooring Feel Better Underfoot?
It can, but the difference depends on how the floor is constructed.
A quality 9mm floor may feel more substantial than a thinner product, particularly when the additional thickness comes from the rigid core or acoustic backing.
However, underfoot feel is also influenced by:
- Core density
- Attached underlay
- Subfloor construction
- Installation quality
- Plank dimensions
The best way to judge this is to compare actual samples rather than assuming that every 9mm product will feel better than every 7mm product.
Is 9mm Hybrid Flooring Quieter Than 7mm?
Potentially — but thickness alone doesn’t determine acoustic performance.
Noise transmission depends on the complete flooring system, including:
- Core construction
- Attached acoustic backing
- Flooring density
- Subfloor
- Building construction
- Installation method
This becomes particularly important in apartments and multi-level buildings.
If noise reduction matters, compare the product’s actual acoustic test results rather than assuming the thicker floor is automatically quieter.
Does Thicker Hybrid Flooring Fix an Uneven Subfloor?
No.
This is an important misconception.
A thicker rigid plank may feel more substantial, but it does not replace proper subfloor preparation.
An uneven subfloor can contribute to:
- Movement underfoot
- Clicking or squeaking
- Stress on locking joints
- Gaps between boards
- Premature joint failure
Never use a thicker floor as a substitute for subfloor preparation. The subfloor still needs to meet the flooring manufacturer’s flatness requirements.
The Click-Lock System Matters More Than You Might Think
Most hybrid flooring is installed as a floating floor using a click-lock system.
Those joints are responsible for keeping individual planks connected across the floor.
Joint quality therefore matters.
When comparing products, consider:
- Locking profile
- Core density around the joint
- Manufacturing precision
- Installation requirements
- Product warranty
A thicker board may allow a more substantial locking profile, but thickness alone does not guarantee a stronger locking system.
Don’t Forget the Attached Underlay
Many hybrid floors include acoustic underlay attached to the bottom of each plank.
This backing can contribute to:
- Acoustic performance
- Underfoot feel
- Overall plank thickness
That last point is important.
If Product A is advertised as 7mm and Product B as 9mm, you need to know how much of each measurement comes from the rigid flooring body and how much comes from the attached backing.
Ask your flooring supplier:
“Does the advertised thickness include the attached underlay?”
Floor Height Matters More Than You Think
Thicker isn’t always more convenient during a renovation.
The finished flooring height can affect transitions to:
- Tiles
- Carpet
- Existing timber flooring
- Sliding doors
- External doors
- Built-in cabinetry
- Stair nosings
- Adjacent rooms
The difference between 7mm and 9mm sounds small, but every millimetre can matter when trying to achieve a clean transition between existing surfaces.
For some renovations, a quality lower-profile product may actually be the better choice.
What Thickness Is Best for a Busy Family Home?
For homes with children, pets and high foot traffic, don’t start with the thickness.
Start with the complete specification.
- Wear layer
- Surface finish and coating
- Core construction
- Locking-system quality
- Attached acoustic backing
- Water resistance
- Warranty
- Subfloor requirements
- Total thickness
- Price
If two products are otherwise comparable and the 9mm version provides meaningful improvements for a reasonable additional cost, choosing 9mm can make sense.
But a high-quality 7mm floor can still be an excellent choice for a busy family home.
What Thickness Is Best for a Rental Property?
For many investment properties, a quality 7mm hybrid floor can provide a strong balance between:
- Durability
- Water resistance
- Appearance
- Initial cost
- Installation cost
- Long-term value
Paying more for 9mm may be worthwhile in a premium rental or when the product also offers meaningful improvements in acoustics, core construction or other specifications.
Otherwise, paying extra for thickness alone may provide limited benefit.
So, Is 9mm Worth Paying More For?
Sometimes.
Instead of asking:
“Is 9mm better than 7mm?”
ask:
“What am I getting for the extra money?”
The additional cost may be justified if the 9mm product provides:
- Better core construction
- Better locking system
- Improved acoustic performance
- Higher-quality attached underlay
- Better surface specification
- Stronger warranty
- Better overall manufacturing quality
Don’t pay more simply for extra millimetres. Pay more when those millimetres are part of a genuinely better floor.

Our Verdict: 7mm or 9mm Hybrid Flooring?
For many Melbourne homes, a quality 7mm hybrid floor is already enough.
You do not need to automatically upgrade to 9mm simply because it is thicker.
A well-made 7mm product with a good wear layer, dense rigid core, reliable locking system and suitable acoustic backing can provide excellent residential performance.
A 9mm floor becomes more attractive when the additional thickness contributes to meaningful improvements in construction, acoustics, underfoot feel or overall product quality.
Choose 7mm Hybrid Flooring If:
- You want strong value for money
- The product has good overall specifications
- It has an appropriate wear layer
- Your subfloor is correctly prepared
- Finished floor height matters
- You don’t need additional premium features
Consider 9mm Hybrid Flooring If:
- It has a genuinely better core construction
- Acoustic performance is important
- It includes a higher-quality backing system
- You prefer a more substantial feel
- The overall specification is stronger
- The price difference is reasonable
Click Floor Verdict: Don’t choose between 7mm and 9mm by thickness alone. For many homes, a high-quality 7mm hybrid floor is more than sufficient. Choose 9mm when the extra thickness comes with meaningful improvements in the overall flooring system.
Frequently Asked Questions
Is 7mm hybrid flooring good?
Yes. A quality 7mm hybrid floor can be an excellent option for residential living rooms, kitchens, dining areas, hallways and bedrooms.
The complete product specification matters more than thickness alone.
Is 9mm hybrid flooring better than 7mm?
Not automatically.
A 9mm floor may provide a more substantial construction, but overall quality depends on the core, wear layer, locking system, acoustic backing and manufacturing quality.
What is the best thickness for hybrid flooring?
There is no single ideal thickness for every home. Quality products around the 7–9mm range can both be suitable for residential applications.
Choose according to the complete specification and requirements of your project.
Is thicker hybrid flooring more scratch-resistant?
Not necessarily.
Scratch resistance is influenced more directly by the wear layer, surface coating and overall surface construction than by total plank thickness.
Is a 0.5mm wear layer good?
A 0.5mm wear layer can be a strong specification for busy residential applications.
However, it should still be considered alongside surface coating, core quality, locking system and overall manufacturing quality.
Does thicker hybrid flooring hide an uneven subfloor?
No.
The subfloor must still meet the manufacturer’s flatness requirements. A thicker floor should not be used as a substitute for correct subfloor preparation.
Does hybrid flooring thickness include underlay?
It often does, but this varies by product.
Always confirm whether the advertised thickness includes the attached acoustic underlay.
