Most charts are on DE size paper 1068 x 715, as this is our ideal size when compiling.

If folding a chart, the following table provides guidance on where we would put the fold lines. Add 10mm to the Y axis to compare to the above table. This is based on our Print On Demand charts which are printed on 841mm width paper.

		X axis dimensions (rotated and padded image)
		710 mm (Trim line at 710 mm)	831 mm (Trim line not required)
Y axis dimensions (rotated and padded image)	524 mm	X-Fold = No Y-Fold = No	This format is not used
	1058 mm	X-Fold = No Y-Fold = 529	This format is not used
	1179 mm	X-Fold = No Y-Folds = Y-dimension – 529 Y-dimension – 1063	X-Fold = 710 Y-Folds = Y-dimension – 529 Y-dimension – 1063
	1260 mm
	1290+ mm

This does not provide a clear answer to the question of what are the dimensions of folded BA Charts. This is the typical question we receive from captains, managers, naval architects etc who are producing or specifying a chart table, or chart drawer.
