English Paper Piecing Number of Hexagons Calculator

Calculate the number of hexagons required for a quilt. What you need to know is how big you want the quilt to be and what size hexagons you will be using.

The Variables

W = width of quilt

L = length of quilt

d = size of hexagon

The number of columns, rows, hexagons and half hexagons

Always round up to nearest whole number.

# columns = X =	W
	1.732

# rows = Y =	2L - d
	3d

# hexagons =	L - 2d	(2X-1) + X
	3d

# half hexagons =	2L - 4d
	3d

Example (Double size quilt)

W = 80", L = 95", d = 1"

# columns = X =	W	=	80	= 47
	1.732		1.732

# rows = Y =	2L - d	=	2(95) - 1	= 63
	3d		3(1)

# hexagons =	L - 2d	(2X-1) + X	=	95 - 2(1)	(2(47) - 1) + 47 = 2930
	3d			3(1)

# half hexagons =	2L - 4d	=	2(95) - 4(1)	= 62
	3d		3(1)

Actual Size of Quilt

W = X(1.732) = 47(1.732) = 81.40"

L =	Y - 1	3d + 2d =	63 - 1	3(1) + 2(1) = 95"
