How can you measure knit fabric?

Answer 1

You use a gauge or tape measure and count how many stitches per inch.

It may not be a whole number, though.

Example:

You may have 4 1/2 stitches per inch. If you wanted to know how many stitches you needed to cast on for the desired measurement, you would multiply the number of stitches per inch by the number of inches you needed.

Example II:

If you neede a garment to finish at 40 inches, you would be making two pieces, with each being 20 inches.

Example III:

So if you had 4 1/2 inches per stitc, you would multiply this by 20 inches and you would need to cast on 90 stitches, adding 2 stitches for sewing so a total of 92 stitches for each side. This would be a total of 92 stitches per side.
