This is a great little app for calculating the size of material whe you need to create a hexagon of a particular size, just enter the dimension you know and it will calculate the remainder.

This is especially useful for working out material size needed when making multiples to reduce waste.

for example:-

if we need to create a hexagon with a side length of 40mm we would use the calculator to work out we need a piece of material 69.28 mm wide ( flat to flat) by 80 mm long (point to point), then to finish the hexagon we just make two cuts at each end at 60 degrees.

  1. This would have been very useful if I’d found it yesterday, but it will be handy tomorrow, thank you.

  2. Very useful calculator. It would be nice if all the variables were related back to the diagram, e.g. Flat to Flat (2r), Point to Point (2R). I figured it all out, but I think it could be easier to understand with this minor addition. Thanks for sharing this! Recently fought my way through some irregular hexagons, and your sled will be most useful in the future.
