How It Works
Laminate flooring is sold by the box, with each box covering a set number of square feet. Calculate your room area, add waste, and divide by box coverage to find how many boxes you need.
The basic rule:
- Measure your room at its longest and widest points — include closets if you're extending the floor
- Add 10% waste for standard straight installation, 15% for diagonal layouts or complex rooms with many cuts
- Laminate planks click together — always stagger end joints by at least 12 inches row to row
Laminate flooring typically comes in boxes of 8-10 planks covering 18-24 sq ft per box. Unlike hardwood, laminate cannot be refinished, so keep a few extra planks stored flat for future repairs. Acclimate planks in the room for 48 hours before installation.
Tips & Considerations
- Double-check your room length before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both total sq ft needed and boxes needed — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to plan your projects.
- If you're unsure about your price per sq ft, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How much laminate flooring do I need?
Multiply your room's length by width to get square footage, then add 10% for waste. For example, a 12×14 room is 168 sq ft — with 10% waste, you need about 185 sq ft. Divide by the box coverage (usually 20-24 sq ft) to get the number of boxes.
How much does laminate flooring cost?
Laminate flooring ranges from $1-$6 per square foot for materials. Budget laminate runs $1-$2, mid-range $2-$4, and premium waterproof laminate $4-$6. Professional installation adds $2-$4 per square foot. DIY installation is common and saves significantly on labor costs.
How many planks come in a box of laminate flooring?
Most laminate flooring boxes contain 7-10 planks covering 18-24 square feet. The exact count depends on plank dimensions. Standard 5"×48" planks typically yield about 8 planks per box (20 sq ft). Always check the box label for exact coverage.
Do I need underlayment for laminate flooring?
Yes, underlayment is essential for laminate flooring. It provides moisture protection, sound dampening, and cushion. Some laminate planks come with pre-attached underlayment. If not, buy separate underlayment — typically 100-200 sq ft rolls for $20-$50. Don't double up if the plank already has padding.
Can I install laminate in a bathroom?
Standard laminate is NOT recommended for bathrooms due to moisture sensitivity. However, waterproof laminate (with a rigid core and sealed edges) can handle bathroom moisture. Look for products specifically rated as 'waterproof' rather than just 'water-resistant.' Vinyl plank flooring is generally a better choice for wet areas.
How long does laminate flooring last?
Quality laminate flooring lasts 15-25 years with proper care. AC-rated laminate (AC3 for residential, AC4 for commercial) indicates durability. Unlike hardwood, laminate cannot be sanded and refinished. Extend its life by using furniture pads, keeping it dry, and avoiding abrasive cleaners.
