Result

135 tiles

Buy about 135 tiles for this tile project.

Adjusted area
134.4 sq ft
Tile coverage
1 sq ft/tile
What to do next

Use this as an ordering estimate, then check room area, layout, cuts, waste factor, pattern direction, breakage, transitions, and whether you need extra material from the same lot.

Quick answer

Quick answer

With the sample inputs, this calculator returns 135 tiles. Adjusted area: 134.4 sq ft. Use 135 tiles as a material estimate, then account for waste, full-box rounding, closets, cuts, pattern direction, and future repair pieces.

Our calculator pages are built to show the formula, explain the inputs, provide examples, and highlight assumptions so readers can understand how each result is estimated.

Results are estimates based on the inputs provided and the assumptions shown on this page. For financial, tax, legal, medical, or other high-stakes decisions, verify results with a qualified professional or official source.

How to use this calculator

The calculator adds waste to project area, then divides by tile coverage.

When to round up

Round up for diagonal layouts, patterns, breakage, niches, and future repairs.

When to use this calculator

  • Estimating flooring or tile before ordering
  • Checking cuts, waste factor, pattern direction, and breakage
  • Planning transitions, stairs, closets, and extra material

Tips for better estimates

  • Measure each room or closet separately and sketch the layout before ordering.
  • Increase the waste factor for diagonal patterns, many cuts, stairs, transitions, or fragile tile.
  • Order extra material from the same lot when matching color, grain, or pattern later would be difficult.

How this calculator is reviewed

This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers room area, layout, cuts, waste factor, pattern direction, breakage, transitions, and ordering extra material.

The sample result is covered by automated tests, and the page links to supporting guides so readers can check the assumptions before acting. This review note is current for May 2026. If a formula, label, or assumption looks off, send the page URL and your inputs through the contact page.

Formula and methodology

The calculator converts measurements and coverage assumptions into material quantity or project cost.

Result details: This page uses the inputs above to show adjusted area and tile coverage in the result area.

Assumptions to check

The key inputs are Project area, Area per tile, Waste allowance. Confirm room area, layout, cuts, waste factor, pattern direction, breakage, transitions, and extra material before ordering flooring or tile.

Worked example

Example inputs: Project area: 120 sq ft; Area per tile: 1 sq ft; Waste allowance: 12 %. With those values, the calculator returns 135 tiles. Buy about 135 tiles for this tile project.

Flooring waste checks

Flooring waste checks by layout
Simple square roomOften 5% to 8% extra material
Typical plank flooringOften 8% to 10% for cuts and layout
Diagonal tile or patternOften 12% to 15% for pattern direction and breakage
Future repairsSave extra material from the same lot

Example scenarios

  • Use 135 tiles as the first order quantity, then compare it with full-box coverage and the room layout.
  • Diagonal tile, stair carpet, closets, and many doorway transitions usually need a larger waste factor.
  • Save extra flooring or tile from the same lot for breakage and future repairs.

FAQs

Tile Calculator questions

Can I use this as my final flooring order?

Use it as a planning estimate, then confirm room area, layout, cuts, waste factor, pattern direction, breakage, transitions, and full-box ordering.

Should I add extra flooring?

Yes. Extra material helps cover cuts, damaged pieces, pattern matching, future repairs, and lot-matching issues.

What should I check before buying?

Check room measurements, plank or tile direction, boxes per carton, transitions, stair pieces, underlayment, trim, and return policy.

Is the tile calculator exact?

No. It is a tile planning estimate. Confirm project area, tile size, grout layout, cuts, waste factor, pattern direction, breakage, and transition details before buying.

What inputs matter most?

Project area, tile size, and waste percentage drive the result.

Should I add a safety margin?

Usually yes. Add a buffer for measurement error, damaged material, layout changes, products sold in full units, and the extra material that fits this specific project.

Common planning mistakes

Forgetting closets and transitions, using too small a waste factor, ignoring pattern direction, undercounting cuts or breakage, and ordering too little extra material for repairs.
