The Variables
W = width of quilt
L = length of quilt
d = size
of hexagon (finished)
(decimal, 1/4" hexagon is .25)

The
Equations - Always round up to
nearest whole number.
| # columns = X = W / (d * 1.732) |
| |
| # rows = Y = (2L - d) / 3d |
| If Y is even, subtract 1 so that Y is odd. |
| |
| # hexagons = (((Y3 / 2) + 0.5) * X2) + (((Y3 / 2) -
0.5) * ( X2 - 1)) |
| |
| # half hexagons = ((Y3 / 2) - 0.5) * 2 |
| |
Example (Double size quilt)
W = 80", L
= 95", d = 1"
| # columns = X = 80 / (1 * 1.732) = 46.189 = 47 |
| |
| # rows = Y = ((2 * 95) - 1) / (3 * 1) = 63 |
| |
| # hexagons = (((63 / 2) + 0.5) * 47) + (((63 / 2) -
0.5) * ( 47 - 1)) = 2930 |
| |
| # half hexagons = ((63 / 2) - 0.5) * 2 = 62 |
| |
Actual Size of Quilt
|
W = Xd(1.732) = 47(1)(1.732) = 81.40"
|
| |
|
L = (((Y - 1) / 2) * 3 d) + 2 d = ((15-1)/2) * (3)(1)
+ (2)(1) = 23
