The shape of a stitch is highly dependent upon how the stitch is formed.   To illustrate this, I will show a pattern that has been "fixed" to look the same with 2 different stitch types.
A stockinette stitch has a kind of squat looking stitch: it is wider than it is high.
So the pattern would need to be elongated (or narrowed) in order for it to look correct when knitted.
This pattern is 24 stitches wide and 40 rows high.
On the other hand, the birdseye jacquard has a lanky looking stitch: it is taller than it is wide.
In this case, the pattern needs to be shortened (or widened) to compensate.
This pattern is 40 stitches wide and 26 rows high.
