Hexagon Area Calculator

What is the Hexagon Area Calculator?

Calculate the area and perimeter of a regular hexagon. Regular hexagons tile a surface without gaps, which is why they appear in floor tiles, honeycombs and garden pavers.

How to use the Hexagon Area Calculator

1. Enter your side length.
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: area, perimeter, long diagonal.
4. Use the 📊 chart to see the result visually, then copy or share it.

Formula and method

Worked example

With side length = 4, the Hexagon Area Calculator returns area: 41.5692193817; perimeter: 24; long diagonal: 8.

Where the Hexagon Area Calculator helps in real life

You are tiling a bathroom with 8-inch hexagonal tiles. The area of one tile tells you how many you need for the floor, before adding waste for cuts.

A landscaper designs a hexagonal patio with 3 m sides. The calculator gives its area for pavers and its perimeter for edging.

Common mistakes to avoid

• Using the formula on an irregular six-sided shape.
• Measuring across corners when the tool expects side length.
• Mixing inches and centimeters.
• Forgetting to add waste when estimating tiles.

💡 Practical tip: A regular hexagon splits into six equilateral triangles, which is where its area formula comes from.

Tips for better results

• Measure one straight edge of the hexagon.
• Divide the floor area by one tile’s area for a rough count.
• Add 10–15% for cuts along walls.
