A lot of shoppers get stuck on one number when buying vinyl plank flooring – the overall thickness. It sounds like the easiest shortcut. Thicker must be better, right?
Sometimes, yes. But not always.
If you’re asking what thickness LVP should I buy, the better answer is this: buy the thickness that fits your subfloor, traffic level, comfort expectations, and budget. A thicker plank can feel more solid underfoot and help hide minor subfloor imperfections, but wear layer, installation quality, and the condition of the floor underneath matter just as much.
What thickness LVP should I buy for my home?
Most homeowners do well with LVP in the 5 mm to 8 mm range for everyday living spaces. That range usually offers a good balance of durability, feel, noise control, and cost.
If you’re updating a low-traffic guest room or a rental unit where budget is the main priority, products around 4 mm can work. If you’re flooring a busy main level, kitchen, hallway, or family room, moving up into the 5 mm to 7 mm range is often a smarter long-term decision. For homeowners who want a more substantial feel or have a subfloor that isn’t perfectly smooth, 7 mm to 8 mm can be worth the extra cost.
That said, thickness alone doesn’t tell you how well the floor will hold up to dogs, kids, rolling chairs, spills, and daily wear. That’s where wear layer enters the conversation.
Thickness and wear layer are not the same thing
This is the mistake that causes the most confusion.
Overall plank thickness is the total height of the product. Wear layer is the clear protective top layer that helps resist scratches, scuffs, and stains. You can have a thicker plank with a modest wear layer, or a thinner plank with a stronger wear layer. Those are two different products built for two different priorities.
If your biggest concern is comfort and a more forgiving feel underfoot, thickness matters more. If your biggest concern is surface durability, especially with pets or heavy foot traffic, the wear layer matters more.
As a practical rule, many homeowners should look for a floor with both a respectable body thickness and a wear layer that matches the room’s use. A 5 mm or 6 mm plank with a solid wear layer is often a better buy than chasing the thickest product on the shelf without looking at the top coating.
How thick should LVP be in different rooms?
Different rooms ask different things from a floor.
Bedrooms and low-traffic spaces
In bedrooms, home offices, and guest rooms, you usually don’t need the thickest LVP available. A 4 mm to 5 mm product can perform well if the subfloor is in good shape and the product has a wear layer appropriate for light residential use.
This can be a sensible place to save money without creating problems later.
Kitchens, living rooms, and hallways
These are the rooms where many homeowners should avoid going too thin. Daily foot traffic, chair movement, dropped items, pets, and constant use put more stress on the floor. In these spaces, 5 mm to 7 mm is often the sweet spot.
That extra structure tends to improve comfort, reduce hollow sound, and give the floor a more substantial feel.
Bathrooms and laundry areas
LVP is popular in spaces where moisture is a concern, but thickness is only part of the equation here. Water resistance comes from the product’s construction and the quality of installation, especially at edges and transitions. A thicker plank can feel better, but it won’t fix poor seam placement or bad prep.
In wet-prone areas, product quality and installation discipline matter more than chasing maximum thickness.
Rentals and turnover projects
For landlords and property managers, the best thickness is usually the one that balances upfront cost with replacement cycle. Too thin, and you may deal with more movement, more telegraphing from the subfloor, and a less durable feel. Too expensive, and the return may not be there.
For many rental applications, a well-chosen 4.5 mm to 5.5 mm product with a good wear layer is a practical middle ground.
Why thicker LVP can be worth it
There are real advantages to moving up in thickness.
A thicker plank often feels sturdier underfoot. It can sound quieter, especially in open-plan areas. It may also bridge over very minor subfloor inconsistencies a bit better than an entry-level product, though no vinyl floor should be used to ignore proper floor prep.
Homeowners also tend to notice the difference in feel. Thin LVP can work, but it can sometimes sound or feel a little lighter than expected, particularly over imperfect substrates. If you’re investing in a visible main-floor update, that added solidity can make the finished project feel more polished.
When thicker LVP is not necessary
There are also cases where paying for extra thickness doesn’t deliver much value.
If the subfloor is already flat and properly prepared, the room has light traffic, and the flooring is being installed in a secondary area, a thinner product can perform just fine. In those situations, the better move may be to buy a product with stronger scratch resistance or a better visual instead of simply buying more thickness.
You also want to watch total floor height. If you’re matching new flooring to adjacent rooms, thicker planks can create transition issues around doorways, appliances, baseboards, or existing hard surfaces. A product that is technically better on paper is not always better for the project as a whole.
What thickness LVP should I buy if I have pets or kids?
For active households, start by looking at wear layer and surface finish, then use thickness as your secondary filter.
A family with kids, large dogs, and heavy daily traffic will usually be happier with a mid-range or premium LVP product, often around 5 mm to 7 mm, paired with a stronger wear layer. That combination tends to deliver the balance most busy homes need – a floor that feels solid, cleans easily, and stands up better to scratching and day-to-day abuse.
If you only focus on plank thickness, you can still end up with a floor that shows wear sooner than expected.
The subfloor matters more than many people realize
This is the part many buyers don’t see when comparing samples.
Even an excellent LVP product can disappoint if it’s installed over a subfloor that is uneven, soft, damaged, or not properly prepared. Gaps, movement, edge stress, and premature wear often trace back to prep issues, not just product choice.
Thicker LVP can be a little more forgiving, but it is not a substitute for proper leveling, patching, moisture evaluation, and installation technique. That’s one reason full-service guidance matters. Choosing the right flooring is only half the decision. The other half is making sure the floor beneath it is ready.
A simple way to choose the right thickness
If you’re standing in a showroom or comparing estimates, keep it simple.
If you want the lowest-cost option for a light-use room, 4 mm to 5 mm may be enough. If you want a strong all-around choice for most of the home, 5 mm to 7 mm is usually the safest target. If comfort, sound, and a more substantial feel matter a lot, or if the room gets heavy daily use, 7 mm to 8 mm can make sense.
Then check the wear layer, the warranty, and whether the installation plan includes proper subfloor prep. Those details often separate a floor that looks good for a year from one that performs well for much longer.
For homeowners comparing products in Milford, Franklin, Hopkinton, and nearby areas, local conditions can also influence the recommendation. Older homes, uneven subfloors, and renovation tie-ins with existing flooring all affect what thickness makes the most sense. That is where a measured, project-specific recommendation is more useful than a generic rule.
If you want a practical answer, not just a product spec, Millena Flooring helps homeowners match LVP thickness, wear layer, and installation approach to the actual space – so the floor looks right, feels right, and holds up the way it should.
The best LVP thickness is not the thickest one you can buy. It’s the one that fits the room, the subfloor, and the life happening on top of it.
