How to Calculate
- Choose the unit.
- Enter the quilt width and length.
- Enter the hexagon side length.
- Click Calculate.
Formula
Columns = floor(width / (sqrt(3) x side)) + 1
Rows = floor(length / (1.5 x side))
Half hexagons = rows - 1
Worked Examples
Example 1: 85 x 95 inches with 3 inch side hexagons gives 17 columns, 21 rows, 344 full hexagons, and 20 half hexagons.
Example 2: 90 x 90 inches with 4 inch side hexagons gives 13 columns, 15 rows, and 184 full hexagons.
Example 3: Smaller hexagons increase the total piece count quickly.
