Free material calculator
Tile box and material cost calculator
Estimate whole tile boxes from measured floor area and allowance. Compare pack sizes and costs without claiming a cut layout.
Start with the example, replace values with your measurements and product label, then compare the complete order. Read the calculation guide.
All prices use one currency. Currency selection changes the label, not exchange rates.

How to use this calculator
Enter each rectangular area once, choose an allowance and enter the coverage printed on the pack. Non-rectangular floors can be split into non-overlapping rectangles.
RoomLedger combines identical products before rounding to full boxes. The result estimates purchasing area, not the number or arrangement of individual pieces. Compare product suitability and installation requirements separately.
What the estimate excludes
Labor, delivery, tax, accessories and detailed layout planning are outside this calculation. Your supplier should verify quantities before you buy. Prices and allowances in the initial form are illustrative, not market data.
