Frequently Asked Questions

How do you calculate laminate flooring needed?

Calculate room area (length × width), add 10-15% waste, then divide by the coverage per box. Formula: Boxes needed = (Area × (1 + Waste%)) / Coverage per box. Round up to the nearest whole box.

How much waste should I add for laminate flooring?

Standard waste factor is 10% for rectangular rooms. For diagonal installation or complex layouts, use 15-20%. The waste accounts for cuts, mistakes, and future repairs.

How much does laminate flooring cost per square foot?

Laminate flooring costs range from $1.50 to $5 per sq ft for materials. Professional installation adds $2-5 per sq ft. Total installed cost: $3.50-10 per sq ft.

How many square feet in a box of laminate?

Laminate boxes typically cover 20-25 sq ft per box. Check your product specifications as coverage varies by brand and plank thickness.

How many boxes of laminate for a 12x12 room?

A 12'×12' room (144 sq ft) with 10% waste needs about 158 sq ft of material. At 22 sq ft per box, you'll need approximately 7-8 boxes.

What's the difference between laminate and vinyl flooring?

Laminate has a photographic layer with a protective wear layer. It's scratch-resistant but not waterproof. Vinyl is waterproof and more durable for bathrooms and basements but typically more expensive.
