Hex Tile Calculator

Hex Tile Calculator

This is the measurement from one flat side to the opposite flat side of the hexagon.

Common grout gaps are 1/16″ (0.0625), 1/8″ (0.125), or 3/16″ (0.1875).

Typically 10-15% for standard layouts, more for complex patterns or irregular rooms.

Convert Room Area to Square Inches var roomAreaSqFeet = roomLengthFeet * roomWidthFeet; var roomAreaSqInches = roomAreaSqFeet * 144; // 1 sq ft = 144 sq inches // 2. Calculate Effective Tile Area (including grout) // Area of a regular hexagon with distance across flats 'd' is (sqrt(3)/2) * d^2 var effectiveDistanceAcrossFlats = hexTileDistanceAcrossFlatsInches + groutGapInches; var effectiveTileAreaSqInches = (Math.sqrt(3) / 2) * Math.pow(effectiveDistanceAcrossFlats, 2); // 3. Calculate Number of Tiles (raw) var rawTilesNeeded = roomAreaSqInches / effectiveTileAreaSqInches; // 4. Calculate Total Tiles (with waste) var totalTilesNeededWithWaste = rawTilesNeeded * (1 + wastePercentage / 100); var finalTilesToOrder = Math.ceil(totalTilesNeededWithWaste); // 5. Calculate Total Area Covered by Tiles (actual tile area, not including grout in tile count) var actualSingleTileAreaSqInches = (Math.sqrt(3) / 2) * Math.pow(hexTileDistanceAcrossFlatsInches, 2); var totalAreaCoveredSqInches = finalTilesToOrder * actualSingleTileAreaSqInches; var totalAreaCoveredSqFeet = totalAreaCoveredSqInches / 144; var resultHtml = '

Understanding the Hex Tile Calculator

Hexagonal tiles, often called hex tiles, bring a unique geometric charm to any space, from kitchen backsplashes to bathroom floors. However, accurately calculating the number of hex tiles needed for a project can be trickier than with standard square or rectangular tiles due to their distinctive shape and the way they tessellate.

Why Use a Hex Tile Calculator?

A specialized hex tile calculator simplifies the estimation process, helping you avoid over-ordering (and wasting money) or under-ordering (and delaying your project). It accounts for critical factors specific to hexagonal shapes and tile installation.

Key Inputs Explained:

• Room Length & Width (feet): These define the total area you intend to cover. Measure the longest and widest points of your space. For irregular rooms, break the area into simpler rectangles and sum them up.
• Hex Tile Distance Across Flats (inches): This is a crucial measurement for hexagonal tiles. It refers to the distance between two parallel flat sides of the hexagon. This is often how hex tiles are sized by manufacturers. Ensure you measure accurately or check the product specifications.
• Grout Gap (inches): The space between individual tiles filled with grout. This gap effectively increases the "footprint" of each tile during calculation. Common grout gaps range from 1/16 inch (0.0625″) for a tighter look to 1/8 inch (0.125″) or 3/16 inch (0.1875″) for a more pronounced grout line.
• Waste Percentage (%): Tiling projects inevitably involve some waste due to cuts, breakage, or mistakes. A waste factor is added to ensure you have enough tiles.
  • 10-15% is standard for simple, rectangular rooms with straightforward layouts.
  • 15-20% or more might be needed for complex patterns (like herringbone with hex tiles), diagonal layouts, irregular room shapes, or if you're a novice DIYer.
  • It's always better to have a few extra tiles for future repairs than to run short.

How the Calculation Works (Simplified):

The calculator first determines the total area of your room in square inches. Then, it calculates the effective area of a single hex tile, including the grout gap, to understand how much space each tile unit (tile + surrounding grout) occupies. By dividing the total room area by this effective tile area, it estimates the raw number of tiles needed. Finally, it applies your specified waste percentage and rounds up to the nearest whole tile, ensuring you have enough for your project.

Tips for Tiling with Hexagons:

• Accurate Measurements: Double-check all your room dimensions and tile specifications.
• Layout Planning: Dry-lay a section of your hex tiles before applying adhesive to visualize the pattern and minimize cuts.
• Cutting Hex Tiles: A wet saw with a diamond blade is essential for clean, precise cuts on ceramic or porcelain hex tiles.
• Grout Color: The grout color can significantly impact the final look of your hex tile installation. Consider how it will contrast or blend with your tiles.
• Order Extra: Even with a waste factor, consider ordering an extra box or two if you have a very large project or a unique tile that might be hard to match later.

Using this Hex Tile Calculator will provide a solid estimate, helping you plan your tiling project with confidence and precision.
