Knitting paper is used to design knitting charts for new patterns. Our grid uses rectangular spaces rather than square to reflect the actual shape of knitting stitches. For most knitting projects, choose the 4:5 ratio. This ratio means that 4 stitches measure the same length as 5 rows (40 stitches = 50 rows). For knitting with oversized, thick yarn or knitting double, the 2:3 ratio may be more appropriate. The 2:3 ratio means that 2 stitches measure the same length as 3 rows (20 stitches = 30 rows).
