Estimate new yardage when you convert a knitting pattern to a new stitch gauge.

From The Knitting Fiend. Your source for free knitting patterns, tips and mindless knitting chatter on the web.

This calculator estimates the amount of yarn you will need if you convert a published knitting pattern to a new gauge, meaning you adjust the number of rows and stitches knit to result in the same size knitted object. Bear in mind, my converter assumes you used the same stitch types as in the original pattern. So, if the original pattern used stockinette, the converted pattern must be knit in stockinette. If the original pattern was knit in a fancy pattern, the new one must use the same fancy stitch pattern. Of course, you must knit the same size item etc.

Other than that, you can use the converter to estimate yardage for sweaters, afghans, shawls or anything. To find other calculators, click calculator page.

Enter stitch and row gauge of published pattern: (If the pattern doesn't give the row gauge, enter 0 in the row gauge.)	stitches per inch and rows per inch.
Enter number of yards required in published pattern.	yards.
Enter stitch and row gauge you are using:	stitches per inch and rows per inch.

Using rule of thumb, assuming the original yardage estimate was correct, you will need approximately yards. (I rounded this to the nearest yard.)

For the record, you will need to knit percent the number of stitches as in the original pattern. Each stitch uses percent the amount of yarn of a stitch in the original pattern.

Due to a number of factors, including the fact that the original pattern may provide an inaccurate estimate, and you may have rounded up or down, or modified the pattern in some way when converting, my estimate may be inaccurate. So, treat it as a rough estimate. But, it's better than nothing.

If in doubt, I advise buying extra yarn. If you have a large gauge difference between the original pattern and your new pattern, be very conservative indeed! In fact, I'd assume due to uncertainties in how you might modify your pattern, you will need between and yds. (This estimated range assumes the original pattern gave a decent yardage estimate. )

Have fun knitting!
