AC wear rating

If the label skips AC rating, ask the store or pick another line — traffic class is the fastest filter for pets and kids.

  • AC3: light residential — bedrooms
  • AC4: general residential — living, dining, hallways
  • AC5: heavy residential / light commercial
  • Higher AC = harder wear layer — better for dogs and kids

Thickness and underfoot feel

7–8 mm: budget, needs flat subfloor. 10–12 mm: quieter, more forgiving of minor dips. Thickness does not equal durability — wear layer AC rating matters more.

Attached pad feels softer but can hide an uneven subfloor. Flatten first; pad does not fix dips that cause click failures.

Water resistance

Basements and ground-level slabs with moisture risk often favor LVP over standard laminate. Compare options in laminate vs vinyl plank.

  • Standard laminate: wipe spills quickly
  • Water-resistant core: waxed edges, short exposure OK
  • Waterproof laminate / LVP: for kitchens and mudrooms — read warranty limits

How many boxes after you pick a product

Once you choose a SKU, enter room size and the carton coverage in the laminate flooring calculator. Default 10% waste covers straight layouts; bump waste for hallways and diagonals.

Pets, kids, and scratch reality

AC4+ with a textured or matte finish hides claw marks better than glossy AC3. Felt pads on chair legs matter more than another millimetre of thickness. Dark floors show dust; mid-tone wood looks hide everyday traffic.

If you have large dogs and a history of standing water near bowls, skip standard laminate and go waterproof LVP — swelling at seams is the #1 laminate complaint in pet homes.

Retail label checklist

Bring a phone photo of the label home. Coverage and AC rating are the two numbers you will enter later — not the marketing name on the endcap.

  • AC rating matches room traffic (AC4+ for hallways)
  • Waterproof claim — read warranty exclusions
  • Box coverage sq ft — enter in calculator, not guess
  • Attached pad? — skip double underlay unless approved
  • Batch/lot number — buy all boxes same run

Frequently asked questions

Matte vs glossy laminate?

Matte and hand-scraped textures hide scratches and dust. High gloss shows every footprint and micro-scratch — less popular now.
