When choosing laminate flooring, thickness is one of the first things many homeowners notice. You may see 6mm, 7mm, 8mm, 10mm and 12mm laminate options and wonder whether thicker automatically means better.
One of the most common comparisons is 8mm vs 12mm laminate flooring.
At first, the difference sounds small. After all, 4mm does not seem like much. But once the floor is installed, that extra thickness can affect how the floor feels, sounds and performs in certain rooms.
The simple answer is this: 12mm laminate is usually thicker, more solid-feeling and better for busy areas, while 8mm laminate can still be a very good choice for many homes if the subfloor is smooth and the product quality is good.
So, which should you buy?
This guide explains the real difference between 8mm and 12mm laminate flooring, including comfort, durability, sound, price, underlay, room suitability and common buying mistakes.
Laminate flooring thickness refers to the depth of each plank, usually measured in millimetres. For example, an 8mm laminate plank is 8 millimetres thick, while a 12mm laminate plank is 12 millimetres thick.
The thickness normally refers to the main board itself. It does not always include underlay unless the product has attached backing, which is less common with traditional laminate.
Laminate flooring is usually made from several layers. These include a protective wear layer, a decorative design layer, a fibreboard core and a backing layer. The core board makes up most of the thickness.
This is important because thickness can affect the feel and structure of the plank, but it is not the only thing that matters.
A thicker laminate is not automatically more scratch-resistant. Scratch resistance usually depends more on the wear layer, AC rating and product quality.
That means a high-quality 8mm laminate can sometimes be a better choice than a cheap 12mm laminate.
8mm laminate flooring is one of the most popular thicknesses for domestic homes. It offers a good balance of cost, practicality and performance.
It is thick enough for many normal rooms, but usually more affordable than 10mm or 12mm options. This makes it a common choice for homeowners who want a smart finish without overspending.
8mm laminate can work well in:
The key point with 8mm laminate is that the subfloor needs to be in good condition. Because the board is thinner than 12mm, it may not hide minor imperfections as well. If the base underneath is uneven, the floor may feel less stable or make more noise underfoot.
When installed correctly with a good underlay, 8mm laminate can be a very practical and cost-effective choice.
12mm laminate flooring is a thicker laminate option. It is often chosen when homeowners want a more solid, premium feel underfoot.
Because the board is thicker, it can feel closer to real wood flooring than thinner laminate. It can also help reduce the hollow sound sometimes associated with floating floors.
12mm laminate can work well in:
It is often more expensive than 8mm laminate, but the extra cost may be worthwhile in rooms where comfort, sound and long-term feel matter.
However, 12mm laminate is not always necessary. For a quiet bedroom or spare room, a good 8mm laminate may be perfectly suitable.
| Feature | 8mm Laminate | 12mm Laminate |
| Thickness | 8 millimetres | 12 millimetres |
| Feel underfoot | Good with quality underlay | More solid and substantial |
| Sound | Can sound slightly lighter | Usually quieter and deeper underfoot |
| Cost | Usually more affordable | Usually more expensive |
| Best for | Bedrooms, living rooms, light to medium traffic | Hallways, family rooms, larger spaces, heavier use |
| Subfloor tolerance | Needs a smooth, level base | Slightly more forgiving, but still needs a good subfloor |
| Installation | Easier to cut and handle | Heavier and thicker to cut |
| Door clearance | Easier where floor height is limited | May create height issues at doors or thresholds |
| Durability | Depends on AC rating and product quality | Often feels stronger, but AC rating still matters |
| Best value | Great for budget-conscious projects | Great for premium feel and busy homes |
This is where many buyers get confused.
12mm laminate often feels stronger because the board is thicker and more rigid. It may handle impact and daily pressure better than a thinner board. It can also feel more stable in busy areas.
However, durability is not only about thickness.
You also need to check:
For example, an 8mm AC4 laminate from a good manufacturer may perform better than a low-quality 12mm laminate with a weaker surface.
If you are comparing two similar-quality products from the same range, the 12mm option will often feel more robust. But do not judge by thickness alone.
In many cases, yes. 12mm laminate usually feels more solid and substantial when you walk on it.
This is one of the main reasons people choose it. It can reduce the lightweight or hollow feeling that some floating laminate floors have, especially in larger rooms.
If you want your floor to feel more premium, 12mm laminate is usually the better choice.
That said, underlay plays a big role. A good 8mm laminate with high-quality underlay can feel much better than a 12mm laminate fitted over a poor underlay or uneven subfloor.
12mm laminate is usually quieter underfoot than 8mm laminate. The thicker board can help reduce the sharp clicking or hollow sound that sometimes happens with thinner floating floors.
This can make a difference in:
However, the underlay is just as important as the plank thickness. If sound reduction matters, choose a good acoustic underlay and make sure it is suitable for your laminate flooring.
Do not simply add extra-thick underlay to solve noise. Underlay that is too soft or too thick can make the floor unstable and may damage the click joints over time.
For hallways, 12mm laminate is usually the better option.
Hallways take a lot of daily wear. Shoes, bags, pets, prams, muddy feet and constant movement all make this one of the hardest-working floors in the home.
A thicker 12mm laminate can feel more stable in this type of area, especially when paired with a strong AC rating and suitable underlay.
However, 8mm laminate can still work in a hallway if it has a good AC rating and the subfloor is smooth. If budget is tight, choose a better-quality 8mm product rather than the cheapest 12mm board.
For busy entrances, look for AC4 or higher.
For bedrooms, 8mm laminate is often enough.
Bedrooms usually have lower foot traffic than hallways, kitchens or family rooms. This means you do not always need the thickest laminate available.
An 8mm laminate with a good underlay can feel comfortable, look stylish and perform well in bedrooms.
Choose 12mm laminate for a bedroom if:
Otherwise, 8mm is usually a sensible and cost-effective option.
Both 8mm and 12mm laminate can work well in living rooms.
If the living room is lightly used, 8mm laminate may be perfectly suitable. It can give you a smart wood-effect look at a good price.
If the living room is the main family space, 12mm laminate may be the better choice. It will usually feel more solid, handle daily traffic well and sound better underfoot.
For open-plan living areas, 12mm laminate can be especially useful because larger spaces often make floor sound and feel more noticeable.
For kitchens, thickness is not the only thing to consider.
A 12mm laminate may feel stronger, but water resistance is more important in a kitchen than thickness alone. Kitchens deal with spills, splashes, food mess, pet bowls and cleaning.
If you want laminate in a kitchen, choose a product that is suitable for kitchen use and offers good moisture resistance. The click system and edge protection are also important.
An 8mm water-resistant laminate may be better for a kitchen than a 12mm product that is not designed for moisture-prone areas.
Always check the product specification before fitting laminate in a kitchen.
For home offices, 12mm laminate is often the stronger choice.
Office chairs, desks and repeated movement can put pressure on the floor. A thicker laminate with a good AC rating can feel more stable and durable.
However, chair castors can still mark laminate over time, regardless of thickness. Use a protective chair mat if you have a rolling office chair.
If the home office is lightly used, 8mm laminate may still be fine. But for daily working from home, 12mm is worth considering.
12mm laminate can be slightly more forgiving than 8mm because it is thicker and more rigid. It may handle tiny surface imperfections better.
But it does not fix a bad subfloor.
Laminate flooring still needs a flat, dry, clean and stable base. If the subfloor has dips, bumps, loose boards or moisture problems, these should be corrected before fitting.
Installing thicker laminate over a poor subfloor can still lead to:
The correct solution is always to prepare the subfloor properly.
Yes, thickness can affect installation in several ways.
8mm laminate is usually easier to cut than 12mm laminate. This can make it slightly easier for DIY projects.
12mm laminate is thicker and may need a sharper blade, better tools and more care when cutting around door frames, pipes and corners.
12mm laminate adds more floor height than 8mm. Once you include underlay, the total build-up can affect doors, thresholds and transitions.
Before buying 12mm laminate, check:
If floor height is limited, 8mm may be easier to work with.
12mm laminate is heavier. This may not matter much once fitted, but it can make transport and handling slightly harder.
Yes, 12mm laminate usually costs more than 8mm laminate.
This is because it uses more material and often sits in a more premium product range. The price difference may be worthwhile in busy rooms, but not always necessary in every part of the home.
When comparing costs, include:
A cheaper 8mm laminate may look like the best deal until you add poor underlay, extra preparation or early replacement costs. A 12mm floor may cost more upfront but feel better for longer in the right space.
Yes, 8mm laminate is good enough for many UK homes.
It can be a smart choice if:
8mm laminate is not a poor choice by default. The quality of the product matters more than the number alone.
12mm laminate is worth it if you want a more solid feel, better sound, greater comfort and a more premium finish.
It is especially worth considering for:
It may not be necessary for a small spare bedroom or low-use room. In those cases, a good 8mm laminate may offer better value.
10mm laminate sits between 8mm and 12mm. It can be a good middle-ground option if you want a more solid feel than 8mm but do not want the cost or height of 12mm.
For many homeowners, 10mm is a practical compromise.
It can work well in:
If you are unsure between 8mm and 12mm, a good 10mm product may be worth comparing.
If you remember one thing from this guide, make it this: do not choose laminate by thickness alone.
The AC rating tells you how much wear the surface is designed to handle.
As a simple guide:
For bedrooms, AC3 may be enough. For hallways, kitchens, family rooms and home offices, AC4 is usually a better option.
A strong AC4 8mm laminate can be better than a weak 12mm laminate with a poor wear surface.
Underlay can make a major difference to how laminate flooring performs.
The right underlay can help with:
If you are fitting laminate over concrete, you may need an underlay with a damp proof membrane or a separate moisture barrier.
If you are fitting upstairs, acoustic underlay may be useful.
If you have underfloor heating, the underlay must be suitable for heat transfer.
Never assume thicker underlay is better. Underlay that is too soft can cause too much movement and may damage the laminate joints.
Best choice: 8mm or 10mm
Bedrooms usually do not need the thickest laminate. A good 8mm product with suitable underlay is often enough.
Best choice: 10mm or 12mm
For main living spaces, 12mm can feel better and sound more solid. If budget matters, a good 8mm or 10mm product can still work.
Best choice: 12mm with AC4 or higher
Hallways are high-traffic zones. Choose a strong surface, good click system and suitable underlay.
Best choice: 10mm or 12mm
Dining chairs can put pressure on the floor, so a thicker product can be useful. Use felt pads under furniture legs.
Best choice: 12mm with chair mat
A thicker laminate can feel more stable under office furniture. A chair mat helps protect the surface from castors.
Best choice: water-resistant laminate first, thickness second
Moisture resistance is more important than thickness in kitchens. Choose a suitable product and clean spills quickly.
Best choice: AC4 or AC5, 8mm to 12mm depending on budget
For rentals, durability and value matter. A strong AC rating is essential.
12mm often feels better, but it is not automatically the best option for every room. A quality 8mm product may be better value in low-traffic spaces.
Thickness does not replace surface durability. Always check AC rating.
Good laminate can feel disappointing with the wrong underlay. Choose underlay based on the room and subfloor.
A thicker floor can create problems with doors and thresholds. Always check floor build-up before buying.
Thicker laminate may hide tiny imperfections, but it cannot fix a poor subfloor. Preparation is essential.
Cheap laminate may cost less upfront, but it may not perform well in busy areas. Compare specification, not just price.
Laminate colours can look different online. Always order samples and view them in your own room.
So, which is better: 8mm or 12mm laminate flooring?
The honest answer is that it depends on the room.
Choose 8mm laminate if you want a cost-effective floor for bedrooms, spare rooms, living rooms or areas with light to medium traffic. It is a good option when the subfloor is smooth and you choose a quality product with the right AC rating.
Choose 12mm laminate if you want a more solid, premium feel underfoot. It is better for busy living rooms, hallways, dining rooms, home offices and larger spaces where sound and comfort matter.
For most UK homes, 8mm laminate offers excellent value, while 12mm laminate offers a more substantial finish. Neither is automatically right or wrong.
The best laminate floor is the one that matches your room, subfloor, lifestyle and budget.
Before buying, compare the AC rating, water resistance, underlay requirement, warranty, plank design and total installation cost. And always order samples first so you can see how the colour and texture look in your own home.

Yes, 8mm laminate flooring is good enough for many homes, especially bedrooms, living rooms and lower-traffic areas. Choose a good-quality product with the right AC rating and suitable underlay.
12mm laminate usually feels more solid, sounds quieter and works better in busy rooms. However, a high-quality 8mm laminate can still be a very good choice.
Not always. Thickness can help with feel and stability, but lifespan also depends on AC rating, wear layer, product quality, fitting and maintenance.
8mm laminate can work in hallways if it has a strong AC rating and is fitted over a good subfloor. For very busy hallways, 12mm laminate is often a better choice.
12mm laminate is worth it for busy rooms, larger spaces and areas where you want a more premium feel. It may not be necessary for spare bedrooms or light-use rooms.
8mm laminate is usually suitable for bedrooms because they normally have lower foot traffic. Add a good underlay for comfort and sound.
10mm or 12mm laminate is often best for main living rooms, especially in busy family homes. 8mm can still work if the product quality is good.
12mm laminate can be slightly harder to cut and handle because it is thicker and heavier. It may also create more floor height issues around doors and thresholds.
Yes, most 12mm laminate flooring still needs suitable underlay unless the product specifically has attached backing and the manufacturer says no separate underlay is needed.
AC rating is usually more important for surface durability. Thickness affects feel, sound and stability, while AC rating helps show how much wear the floor is designed to handle.
