If you're about to install laminate, hardwood, vinyl, or tile flooring, the first step is figuring out one thing:
"How much flooring do I actually need?"
Too little, and you'll be scrambling for extra boxes mid-project. Too much, and you'll overspend on materials that sit in storage.
That's where our free Flooring Calculator comes in — a simple, accurate tool to help you measure, plan, and buy the right amount of flooring for any room in your home.

Step 1: Measure the Room
Start with the basics:
- Length × Width = Total square footage
- For oddly shaped rooms, break them into rectangles and add them up
- Don't forget closets, hallways, or alcoves if they'll be covered
Step 2: Add a Waste Allowance
No flooring project is perfect — there will always be:
- Cut pieces
- Mismatched grains or planks
- Damaged pieces
- Spare flooring for future repairs
Most pros recommend adding 5% to 15% waste depending on the type of flooring and layout complexity.
✅ Pro Tip:
- 5% waste for square rooms
- 10% for complex layouts
- 15% for diagonal or herringbone patterns
Our Flooring Calculator includes a built-in waste option so you don't have to guess.
Step 3: Estimate Boxes or Planks
Flooring is usually sold in boxes, with each box covering a fixed area — for example:
| Flooring Type | Common Box Coverage |
|---|---|
| Laminate | 18–25 sq ft |
| Vinyl Planks | 20–30 sq ft |
| Hardwood | 18–22 sq ft |
| Tile Flooring | 10–15 sq ft |
Using our calculator, you can enter the coverage per box, and it'll show you how many boxes you'll need — rounded up to avoid shortage.
Example: Bedroom Flooring Estimate
Room Size: 12 ft × 10 ft = 120 sq ft
Waste: 10% → 120 × 1.10 = 132 sq ft needed
Box Coverage: 22 sq ft per box
Boxes Needed: 132 ÷ 22 = 6 boxes
Works for Every Room in the House
The calculator is perfect for:
- ✅ Bedrooms & Living Rooms
- ✅ Kitchens & Dining Areas
- ✅ Hallways & Entryways
- ✅ Bathrooms & Laundry Rooms
- ✅ Basements, Attics & Garages
You can switch between imperial or metric units, making it easy to plan flooring projects anywhere in the world.
