Thick or Thin Yarn

Although we all know that with the same yarn small needles will produce a smaller piece of knitting than bigger needles will, and likewise using the same needles with a fine yarn will make a smaller piece of knitting than a thick yarn will, but what is the relationship between length of yarn and area of knitting when using different yarns or needles?

I knitted three test swatches, wetted and blocked them and then made a few measurements. Each swatch was 20 stitches wide, long-tail thumb method cast on, 11 rows of knitting and regular cast off, making a total of 280 stitches.

The yarns I used were King Cole Zig-Zag 4 ply which I measured at 21 wraps per inch and an unknown Aran weight acrylic which I measured at 14 wraps per inch.
(Ravelry suggest that 4 ply is 14 wpi and Aran is 8 wpi but I can never measure as few wraps as they suggest.)

three swatches

  4 ply - 2mm needles 4 ply- 4 mm needles Aran - 4mm needles
width of 10 sts 3.4 cm 5.8 cm 6.8 cm
Depth of 10 sts 2.4 cm 3.7 cm 4.0 cm
Area of 100 sts 8.18 sq cm 21.46 sq cm 27.2 sq cm
Length of yarn for 280 sts 2.38 m 5.06 m 5.89 m
Length of yarn for 100 sts 0.85 m 1.81 m 2.10 m
Area covered by 1m of yarn 9.62 sq cm 11.86 sq cm 12.95 sq cm

Whilst just three swatches and sets of results does not constitute a proper scientific experiment it does suggest that increasing the needle size has more effect on the size of a piece of knitting than increasing the thickness/diameter of the yarn.
