Understanding Flooring Materials
How Flooring Is Sold
Most hard flooring (hardwood, laminate, vinyl plank) is sold in boxes containing a set number of planks that cover a specific square footage. Carpet is typically sold by the square yard. Our calculator converts your room dimensions into the exact number of boxes or square yards you need to purchase.
Flooring Comparison
| Type | Cost/sq ft | Durability | Best For |
|---|---|---|---|
| Hardwood | $3–$8+ | 25+ years | Living rooms, bedrooms |
| Laminate | $1–$4 | 10–20 years | Any dry room, DIY projects |
| Vinyl Plank | $2–$5 | 15–25 years | Kitchens, bathrooms, basements |
| Tile | $2–$10 | 20+ years | Bathrooms, kitchens, entryways |
| Carpet | $1–$5 | 5–15 years | Bedrooms, family rooms |
Why Waste Factor Matters
The waste factor accounts for cuts at walls and doorways, pattern matching requirements, damaged pieces you may find in a box, and future repair pieces. Running short mid-project is far worse than having a few extra planks, so always round up!
Pro Tips for Flooring Installation
Acclimate Flooring 48 Hours Before Installation
Bring flooring boxes into the room at least 48 hours before installation. This lets the material adjust to your home’s temperature and humidity, preventing gaps or buckling after installation.
Always Buy 10–15% Extra for Cuts and Mistakes
Even experienced installers waste material on cuts. The last row almost always needs cutting, and door frames require precision cuts. Keep extra planks for future repairs—flooring colors get discontinued regularly.
Check Subfloor for Levelness (1/8″ per 10 ft max)
An uneven subfloor causes squeaking, gaps, and premature wear. Use a long straightedge to check for dips and high spots. Self-leveling compound can fix minor issues; major unevenness may need professional attention.
Stagger Seams at Least 6 Inches Between Rows
Never align the end joints of adjacent rows. Stagger them by at least 6 inches (12 inches is better) to create a more natural look and improve structural stability.
Leave a 1/4″ Expansion Gap Around All Walls
Floating floors need room to expand and contract with temperature and humidity changes. Use spacers to maintain a consistent 1/4-inch gap around all walls, pipes, and fixed objects. This gap will be hidden by baseboards.
Frequently Asked Questions
A 12x12 room is 144 square feet. With the recommended 10% waste factor, you’ll need about 159 square feet of flooring material. For laminate sold in 25 sq ft boxes, that’s 7 boxes. Use our calculator to get a precise estimate for your specific flooring type.
Laminate is made from compressed wood with a photographic layer on top, while vinyl plank (LVP) is 100% synthetic and waterproof. Vinyl plank is better for bathrooms, kitchens, and basements because it can handle moisture. Laminate tends to look more like real wood and is often cheaper, but it can swell if exposed to standing water.
We recommend buying 10% extra for standard rectangular rooms with straight-lay installation. Add 15% for diagonal patterns or rooms with many corners and angles. For complex layouts or if you’re a beginner installer, 20% extra gives you a comfortable safety margin. Keep leftover pieces for future repairs.
In many cases, yes. Laminate and vinyl plank can often be installed over existing hard floors as long as they’re clean, flat, and dry. You typically can’t install over carpet. Always check the manufacturer’s guidelines and ensure the subfloor is level (within 1/8 inch per 10 feet). Adding new flooring raises the floor height, so check door clearances.
Calculate each room separately using our tool, then add the totals together. This is more accurate than treating connected rooms as one large area. If you’re using the same flooring throughout, buy all materials at once to ensure consistent color matching between batches.
Budget laminate ($1–$2/sq ft) and sheet vinyl ($0.50–$2/sq ft) are the most affordable options. Vinyl plank typically costs $2–$5/sq ft, while hardwood ranges from $3–$8+/sq ft. Keep in mind that cheaper materials may need replacement sooner, so consider long-term value alongside upfront cost.
