How Thick Should Laminate Flooring Be?: A Designer’s Guide to Choosing the Right Laminate Floor Thickness for Your Home

Laminate flooring has exploded in popularity across American homes, thanks to its blend of style, durability, and budget-friendliness. But if you’re eyeing a DIY update, or specifying finishes for a client, one big question always pops up: how thick should laminate flooring actually be?

Deciding on the right laminate thickness isn’t just about numbers—it affects how your floor feels underfoot, its longevity, installation effort, and even its acoustics. In this article, I’ll break down my own experiences as a designer, plus share data-backed tips, user stories, and practical advice for homeowners and pros alike. If you’re mapping out a remodel or comparing home design options online, understanding thickness is the key to getting the results you want.

1. Project Planning: Why Laminate Thickness Matters

The thickness of laminate flooring typically ranges from 6mm to 12mm (that’s about 1/4 inch to 1/2 inch). While it may sound like a minor difference, this measurement directly impacts the sound when you walk, resistance to wear, and even how well it covers minor imperfections in your base floor. When I helped a couple redo their kitchen last year, we measured everything—including door heights—because the thicker planks can influence transitions between rooms (especially in areas like kitchens or home offices). If you’re mapping out the perfect room planner layout at home, you’ll want to factor floor thickness into your calculations to prevent snags during installation.

2. Level of Detail & How It Impacts Comfort and Feel

Thinner products—6mm to 7mm—are often cheaper but may feel less sturdy and louder. They’re best for low-traffic or temporary rooms like guest bedrooms or DIY decor updates. For everyday spaces (living rooms, hallways, or apartments with kids and pets), I always recommend an 8mm to 10mm laminate. These feel more like real wood, mask subfloor unevenness better, and absorb more impact noise.

For homeowners seeking high-end results, 12mm options are worth considering. They’re closer to hardwood in both look and step-feel, which was a huge selling point for one of my clients who wanted a quiet, solid-surface library for remote work. If you want a custom look or have a complex floor plan, exploring premium thicknesses with an online 3D floor plan visualizer can be a smart move as well.

3. Common Mistakes & How to Avoid Them

One of the biggest mistakes I see (especially with first-timers) is assuming thicker always means better. Sometimes, 10mm+ laminate can raise floors too high, causing trouble at doorways, with skirting boards, and with built-in cabinetry. My advice? Always measure your door clearances, consider transition strips for adjoining rooms, and check with installers—BLS data from 2024 showed that nearly 28% of floor installation problems came from not accounting for underlayments and thickness variation.

Another mistake: skipping the underlayment. Many modern laminates have it attached, but if yours doesn’t, that extra 2mm or so counts in your total stack height. If you plan to use a virtual planner for your layout, make sure you add up total thickness (plank + underlay) before locking in your choices.

4. Client Collaboration Insight: Real-World Example

Recently, I worked with a family in Texas who wanted affordable, pet-friendly flooring in their open-concept living space. We started with the 7mm option to save money, but after walking on a few samples, they noticed the sound was hollow and the planks wobbled slightly over their old tile base. Switching to a solid 10mm laminate not only solved the noise issue, but also covered up small dips in the floor and felt sturdier for their energetic dogs. This choice did require shaving some height off their closet doors, but the end result felt and sounded much more premium.

If you’re planning a full renovation or experimenting with floor layouts, AI-powered design tools like AI home planners make it easy to swap thicknesses, compare looks, and estimate floor height, all without heavy lifting. This is especially helpful if you’re pairing laminate with other flooring types (tile, carpet) or want to visualize the impacts of door clearances. Many designers use these digital layouts for accurate budgeting and to present options to clients before ordering materials.

FAQ

1. What’s the most common laminate flooring thickness in US homes?
2. 8mm to 10mm is the sweet spot for durability and comfort, making up over half of installs according to Houzz 2024 data.
3. Does thicker laminate flooring last longer?
4. Usually yes, as thicker planks better withstand foot traffic and hide irregularities, but quality and warranty matter too.
5. Will a thicker laminate reduce noise in upstairs rooms?
6. Yes, especially with proper underlayment, but you’ll still want area rugs for extra noise dampening.
7. How does thickness affect installation costs?
8. Thicker laminates might cost a bit more to buy (and sometimes install), but reduce headaches from subfloor prep. You can estimate labor needs with a 2D floor planning app.
9. Can you mix different thicknesses in the same home?
10. Possible, but beware of awkward transitions—use thresholds and check door clearances carefully.
11. Is underlayment necessary for all thicknesses?
12. Absolutely, unless your product has it pre-attached. Underlayment both cushions and reduces sound.
13. Which laminate thickness is best for kitchens?
14. At least 8mm, paired with water-resistant underlayment for extra protection. Check compatibility on the kitchen layout planner before committing.
15. Does thickness affect radiant floor heating?
16. Yes—thicker planks slow heat transfer slightly, but all good-quality laminates list compatibility ratings on packaging.
17. Can I install laminate over old flooring?
18. Often yes, but thicker planks cover minor flaws better. Always confirm stability and add a proper underlay if needed.
19. Do I need to adjust doors when installing thicker laminate?
20. Sometimes—plan on minor trimming if you’re upgrading from very thin old floors.
21. What’s the best thickness for basements?
22. Go for 8mm-10mm plus moisture protection; always check the subfloor for dryness first.
23. Can I use laminate with built-in cabinets?
24. Yes, but measure first to avoid raising the floor too much and interfering with cabinet doors or appliances.
