AC3 vs AC4 Laminate: Cost, Use Case, and When the Premium Pays
AC3 laminate cost $0.99 to $1.39 per sq ft on the shelf and AC4 $1.89 to $2.99 (Home Depot and Floor & Decor, 13 October 2026). Installed on 400 sq ft that is $1,356 to $1,972 for AC3 against $1,632 to $2,516 for AC4: $276 to $544 more. AC4 survives twice the wear test (at least 4,000 Taber rotations against 2,000); it is not more scratch- or water-resistant because of the class.

Which to Choose
| Room or need | Choose | Why |
|---|---|---|
| Bedroom, office, guest room | AC3 | Light traffic; the lowest price |
| Living room, hallway | AC4 | Heavier traffic wears the surface sooner |
| Kitchen | AC4 with a water claim | The AC class says nothing about water; buy a plank sold as water resistant or waterproof. See kitchen laminate cost |
| Pets | AC4, then check the scratch warranty | AC measures wear, not scratches |
| Entry, heaviest traffic | Consider AC5 | See AC5 laminate cost |
The carton may also show a use class (21 to 23 for homes, 31 to 34 for commercial spaces). That is a separate EN 13329 rating that covers more tests than abrasion; the AC ratings guide explains both.
Common Questions
What is the difference between AC3 and AC4 laminate?
Wear resistance. Under the European standard EN 13329, an AC3 surface must survive at least 2,000 turns of a Taber abrasion test before it shows wear and AC4 at least 4,000. The class says nothing about scratches, fading, stains or water. The US standard, NALFA LF-01, does not use AC classes.
How much more does AC4 laminate cost than AC3?
On the shelf on 13 October 2026, the AC3 planks we price ran $0.99 to $1.39 per sq ft and the AC4 planks $1.89 to $2.99. Installed on 400 sq ft, AC3 comes to $1,356 to $1,972 and AC4 to $1,632 to $2,516, which is $276 to $544 more. Part of the gap is offset because the AC4 planks have an attached pad and need no separate underlayment.
Do I need AC4 in a bedroom?
Not for wear. AC3 suits bedrooms, offices, dry living areas. Choose AC4 where traffic is heavier: living rooms, hallways, kitchens, homes with pets.
Is AC4 laminate better for pets?
For wear, yes: it takes twice the Taber rotations of AC3. For claws, the AC class does not measure scratch resistance (NALFA says so in its white paper); check the maker's scratch or pet warranty instead.
Where is the AC rating printed?
On the product page and usually the carton. Retailers such as Home Depot and Floor & Decor list it in the specifications of the planks we price; check the product page of the plank you buy.
