How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Formula and method

At 44 × 50 cm with 5 cm sides, the layout gives six columns, seven row steps and 36 whole patches.

Columns = ceiling(width / (1.732 × side)); rows = ceiling((2 length − side) / (3 side))

Worked example

Enter these known values and leave the other values blank.

Assumptions and limitations

  • Hex size is the side length, before seam allowances. The captured layout uses 1.732 as an approximation of square root of three and rounds final length upward to whole inches; dimensions near a row boundary can change counts. Check the patch arrangement before cutting.

Common questions

What does this estimate assume?

Hex size is the side length, before seam allowances. The captured layout uses 1.732 as an approximation of square root of three and rounds final length upward to whole inches; dimensions near a row boundary can change counts. Check the patch arrangement before cutting.

Can I find a missing input?

Clear the unknown field and enter compatible known values. The controls retain supported inverse calculations, while rounded counts and one-way outputs stay directional.

References

The layout requires at least one complete hexagon in its length direction. This prevents negative whole- or half-patch counts for undersized targets.
