How to use this hexagon tile square footage calculator
Regular, six-sided hexagon tile when you know the tile's across-flats or across-points measurement.
- Add the finished room, wall, floor, or ceiling dimensions. Split irregular areas into non-overlapping rectangles.
- Choose the measurement unit, enter the tile details, and select a waste percentage that suits the layout.
- Use the coverage printed on the manufacturer's box, then calculate to see area, tile count, and the whole boxes to order.
Measure before you estimate
Measure a single tile from one flat edge to its opposite flat edge, or from one corner to the opposite corner. Select the matching measurement type—these are different dimensions. If the box lists actual coverage per sheet or package, use that coverage because mesh spacing, grout joints, and nominal sizing can differ from an isolated tile-face calculation.
How the calculation works
For across-flats distance d, a regular hexagon's face area is (√3 ÷ 2) × d². For across-points distance D, area is (3√3 ÷ 8) × D². The calculator converts that single-tile area into the selected area unit, applies waste to the floor area, estimates tile count, and rounds boxes up using package coverage when supplied.
Worked example
Example: 2-inch across-flats hexagons
A 100 sq ft floor uses regular hexagons measuring 2 inches across flats, with a 10% waste allowance.
Working: A 2-inch flat-to-flat span gives a geometric face area of √3/2 × 2² = about 3.46 sq in (0.024 sq ft). The 110 sq ft order area divided by that face area is roughly 4,583 individual faces. This theoretical count is only a cross-check; for mesh sheets, use the manufacturer's stated box coverage to order.
Common measurement mistakes
- Confusing the flat-to-flat span with the larger point-to-point span.
- Treating each hexagon as a rectangle using its bounding width and height.
- Using theoretical face area instead of the coverage printed for a mesh-mounted sheet.
Choosing a tile waste percentage
Small hexagons can create many edge cuts; the appropriate allowance depends on floor shape, sheet layout, and perimeter complexity. Ten percent is a starting point for a straightforward area, while detailed borders or many obstructions may justify more. Let manufacturer coverage and installer advice guide the final order.
Always check the product's actual coverage and installation instructions before buying. Cuts, breakage, grout joints, package quantities, and future repair stock can change the final quantity.
Quick answers
Frequently asked questions
What does flat-to-flat mean for hexagon tile?
It is the perpendicular distance between two opposite parallel sides. Point-to-point is the distance between two opposite vertices and is larger for the same hexagon.
Why is box coverage better than the geometric tile count?
Hexagons are commonly sold on mesh sheets. The sheet's layout, grout spacing, and manufacturer packaging affect usable coverage, so box coverage on the label is the preferred purchasing figure.
Does the formula work for any six-sided tile?
The formula assumes a regular hexagon with six equal sides and angles. For elongated or irregular six-sided tile, use the manufacturer's coverage rather than this geometric estimate.
