Tile Calculator
Calculate how many tiles you need for a floor, wall, or backsplash with waste allowance.
Calculated result: 174
Why This Calculation Matters
The Tile Calculator helps you price and order materials correctly the first time. Short-ordering means extra trips, delays, and rushed decisions; over-ordering means wasted money and disposal hassle. A precise takeoff, plus a standard 10% waste factor, is the sweet spot.
How to Use This Calculator
- Enter your values in the input fields, each one has a label and help text explaining what to type.
- Results appear instantly as you type; there's no "calculate" button to press.
- Change any input to compare scenarios side by side.
All math happens in your browser. Nothing you type is sent to a server, saved, or shared.
Ordering & Waste Factor
Always add roughly 10% to the calculated quantity. Cuts, edge losses, breakage, and mistakes happen on every project. A small surplus is far cheaper than a supply run mid-pour or mid-install.
Tile Calculation
- Calculate total area (length × width)
- Add 10% waste (15% for diagonal)
- Divide by area per tile
Common Tile Sizes
- 12×12" = 1 sq ft per tile
- 12×24" = 2 sq ft per tile
- 6×24" = 1 sq ft per tile
- 3×6" subway = 0.125 sq ft per tile
When to Use This Calculator
- Estimate material quantities before ordering, avoid short-loads and wasteful overbuy.
- Price a bid or budget for a customer accurately.
- Spot errors in a supplier's take-off or quote.
Limitations & Common Mistakes
- Add ~10% to material totals for waste, cuts, and breakage.
- Local building codes, load requirements, and soil conditions may change what you need, always confirm with your permit office or structural engineer.
- Prices vary by region and supplier; request current quotes before ordering.
