Knitting Gauge & Pattern Converter
Enter the pattern gauge, your blocked swatch gauge, and the stitch and row counts from the section you want to convert. The calculator scales both directions, rounds to the pattern repeats you enter, and shows how far the rounded result moves from the original dimensions.

Fractional stitch and row counts are proportional intermediates; use the rounded counts in the pattern.
Do not convert row counts for instructions that already say to work until a measured length is reached.
How to use this calculator
- Choose the gauge basis used by both the pattern and your blocked swatch.
- Enter the pattern stitch and row gauge, then enter the stitch and row gauge you measured.
- Enter the original stitch and row counts for the section you are converting.
- Add the stitch multiple, any fixed edge stitches, and the vertical row repeat.
- Use the recommended counts only after checking shaping, length instructions, and repeat placement in the original pattern.
How the conversion is calculated
Gauge conversion starts by preserving the size the pattern intended. The calculator uses one gauge span throughout: 4 inches when you choose the imperial basis, or 10 centimeters when you choose the metric basis. The pattern gauge and your swatch gauge must be measured over the same span.
Let G be the gauge span, Ps and Pr be the pattern stitches and rows per span, As and Ar be your stitches and rows per span, Ns and Nr be the original stitch and row counts, M be the stitch-pattern multiple, E be the fixed extra stitches, and Q be the row repeat.
The pattern's intended dimensions are:
target width = Ns x G / Ps
target height = Nr x G / Pr
If you knit the original counts at your gauge, the unchanged dimensions are Ns x G / As and Nr x G / Ar. The raw converted counts are proportional:
raw stitches = Ns x As / Ps
raw rows = Nr x Ar / Pr
Because knitting instructions need whole repeats, the raw stitch count is rounded to the nearest valid count of the form E + k x M, where k is zero or greater. The raw row count is rounded to the nearest positive multiple of Q. If two choices are equally close, the calculator chooses the larger count and names both alternatives in the notes.
What moves the result most
The largest driver is the ratio between your gauge and the pattern gauge. More stitches per 4 inches, or per 10 centimeters, means each stitch is smaller, so an unchanged stitch count would make the piece narrower. Fewer stitches per span means the same count would knit wider. Rows work the same way: more rows per span make an unchanged row count shorter, while fewer rows make it taller.
The stitch multiple can also move the final width. A small multiple, such as 2 or 4, usually keeps the rounded width close to target. A large cable, lace, or colorwork repeat can force the final count several stitches away from the proportional count. The width and height error rows show that rounding effect after the repeat constraint has been applied.
What this calculator leaves out
This is arithmetic for a section with a known stitch count and row count. It does not redesign armholes, necklines, sleeve caps, raglan rates, short rows, buttonholes, or colorwork placement. It also does not decide whether a different yarn creates the same fabric, drape, ease, or yarn usage.
Do not convert instructions that already say to work until the piece measures a physical length. For those, use the stated measurement and your actual knitting. For shaped sections, check every increase, decrease, bind-off, and repeat placement before carrying one converted count through the whole pattern.
Worked example
Suppose a pattern gives 20 stitches and 28 rows over 4 inches, but your blocked swatch has 22 stitches and 30 rows over 4 inches. A section written as 182 stitches and 240 rows has a target width of 182 x 4 / 20, or 36.4 inches, and a target height of 240 x 4 / 28, or 34.29 inches.
The raw stitch conversion is 182 x 22 / 20, or 200.2 stitches. With a multiple of 4 plus 2 edge stitches, the nearest valid count is 202 stitches. The raw row conversion is 240 x 30 / 28, or 257.14 rows; with a 2-row repeat, the recommendation is 258 rows. Those rounded counts finish at about 36.73 inches wide and 34.4 inches high, which is about 0.9% wider and 0.3% taller than the target.
Common questions
How do I adjust a knitting pattern when my gauge is different?
First calculate the physical size the original stitch or row count was meant to create. Then multiply that size by your measured gauge to get the count you need at your gauge. This calculator does that proportionally and then rounds the result to the stitch and row repeats you enter.
Should I round a converted stitch count up or down?
Round to a count that fits the stitch pattern, not just to the nearest whole number. If the pattern says a multiple of 4 plus 2, valid counts are 2, 6, 10, 14, and so on. This calculator chooses the valid count nearest the raw conversion and rounds upward when two valid choices are equally close.
How do I handle a stitch pattern written as a multiple plus extra stitches?
Enter the repeat as the stitch-pattern multiple and enter the extra stitches separately. For a multiple of 8 plus 3, use 8 for the multiple and 3 for the edge stitches. The recommendation will keep the extra stitches fixed and change only the number of complete repeats.
Does row gauge matter if the pattern gives measurements in inches?
Row gauge matters for instructions written as a fixed number of rows, such as a chart, stripe sequence, or decrease schedule. It matters less for instructions that say to work until the piece measures a certain length. Do not convert those measured-length instructions; knit until the stated length is reached.
Should I measure gauge before or after blocking?
Measure a swatch after washing and blocking it the same way the finished item will be treated. Gauge before blocking can be misleading because many yarns relax, bloom, grow, or tighten after finishing. Use a swatch large enough that edge distortion does not dominate the measurement.
Can this safely resize raglans, sleeve caps, cables, and colorwork?
Use the result as a starting count, not as a complete redesign. Shaping rates, chart placement, cable crossings, colorwork repeats, buttonholes, and neckline depth may all need separate checking. For complex garments, convert each section and shaping interval deliberately rather than applying one percentage everywhere.
