Tile and Flooring Material Calculator
Calculate the number of tiles or flooring planks needed for a room, including waste allowance for cuts and breakage.
Room Length (ft)
Room Width (ft)
Tile / Plank Length (inches)
Tile / Plank Width (inches)
Grout / Gap Size (inches) (0 for planks)
Waste / Overage (%)
Price per Tile / Plank ($) (optional)
Calculate
function tilCalc() { var roomL = parseFloat(document.getElementById('til-room-length').value); var roomW = parseFloat(document.getElementById('til-room-width').value); var tileL = parseFloat(document.getElementById('til-tile-length').value); var tileW = parseFloat(document.getElementById('til-tile-width').value); var grout = parseFloat(document.getElementById('til-grout-gap').value); var waste = parseFloat(document.getElementById('til-waste').value); var price = parseFloat(document.getElementById('til-price').value); var res = document.getElementById('til-result');
// Validation if (isNaN(roomL) || roomL Please enter a valid room length.'; return; } if (isNaN(roomW) || roomW Please enter a valid room width.'; return; } if (isNaN(tileL) || tileL Please enter a valid tile/plank length.'; return; } if (isNaN(tileW) || tileW Please enter a valid tile/plank width.'; return; } if (isNaN(grout) || grout Grout/gap size cannot be negative.'; return; } if (isNaN(waste) || waste 50) { res.innerHTML = 'Waste percentage must be between 0 and 50.'; return; }
// Convert room dimensions to inches var roomLin = roomL * 12; // inches var roomWin = roomW * 12; // inches
// Effective tile dimensions including grout gap // Each tile occupies (tileLength + groutGap) x (tileWidth + groutGap) in the layout var effL = tileL + grout; var effW = tileW + grout;
// Room area in square inches and square feet var roomAreaSqIn = roomLin * roomWin; var roomAreaSqFt = roomL * roomW;
// Tile area in square inches (actual tile, no grout) var tileAreaSqIn = tileL * tileW; var tileAreaSqFt = tileAreaSqIn / 144;
// Number of tiles along each dimension (ceiling to cover full room) var tilesAlongLength = Math.ceil(roomLin / effL); var tilesAlongWidth = Math.ceil(roomWin / effW);
// Base tile count (no waste) var baseTiles = tilesAlongLength * tilesAlongWidth;
// Apply waste factor var wasteFactor = 1 + (waste / 100); var totalTiles = Math.ceil(baseTiles * wasteFactor);
// Coverage area of ordered tiles (sq ft) var coverageSqFt = totalTiles * tileAreaSqFt;
// Boxes — common box sizes: assume user just gets per-tile count // Also compute sq ft of tile needed with waste var sqFtNeeded = roomAreaSqFt * wasteFactor;
// Cost estimate var costHTML = ''; if (!isNaN(price) && price > 0) { var totalCost = totalTiles * price; costHTML = 'Estimated Material Cost$' + totalCost.toFixed(2) + ''; }
res.innerHTML = '### Results ' + '' + 'Room Area' + roomAreaSqFt.toFixed(2) + ' sq ft' + 'Tile / Plank Size' + tileL + '" × ' + tileW + '"' + 'Effective Tile Size (with grout)' + effL.toFixed(3) + '" × ' + effW.toFixed(3) + '"' + 'Tiles Along Length' + tilesAlongLength + '' + 'Tiles Along Width' + tilesAlongWidth + '' + 'Base Tile Count (no waste)' + baseTiles + ' tiles' + 'Waste Allowance' + waste + '%' + 'Total Tiles to Order' + totalTiles + ' tiles' + 'Total Coverage (ordered tiles)' + coverageSqFt.toFixed(2) + ' sq ft' + 'Sq Ft Needed (with waste)' + sqFtNeeded.toFixed(2) + ' sq ft' + costHTML + ''; }
#### Formulas Used
Room Area (sq ft): Room Length (ft) × Room Width (ft)
Effective Tile Size: (Tile Length + Grout Gap) × (Tile Width + Grout Gap) — in inches
Tiles Along Length: ⌈ Room Length (in) ÷ Effective Tile Length ⌉
Tiles Along Width: ⌈ Room Width (in) ÷ Effective Tile Width ⌉
Base Tile Count: Tiles Along Length × Tiles Along Width
Total Tiles to Order: ⌈ Base Tile Count × (1 + Waste% ÷ 100) ⌉
Estimated Cost: Total Tiles × Price per Tile
