Knitting Gauge Swatch & Stitch Converter

Convert horizontal stitch gauge and vertical row gauge independently, align cast-on counts to your pattern stitch multiple (e.g. 6 + 1), generate exact Flat vs. In-the-Round increase/decrease sequences with stitch numbers, and build a row-by-row shaping checklist.

Why Stitch Ratio, Row Ratio & Flat/Round Shaping Must Be Separated

1. Independent Horizontal vs. Vertical Ratios: Your horizontal stitch ratio is 1.182× (18.2%) while your vertical row ratio is 1.133× (13.3%). Applying stitch gauge math to row counts distorts armhole depth and sleeve taper length.

2. Pattern Multiple Rounding: For a pattern repeat of 6n + 1, raw scaled stitches (260 sts) are rounded up to 265 sts (+5 sts) so cables, rib, or lace motifs never break at the seam.

3. Flat vs. In-the-Round Spacing: In the round, K increases divide N stitches into K circular intervals. When knitting flat, we protect both selvedge edges with K 2 at the start and k2 at the end so no increase or decrease sits on a seam stitch.

Knits to 101.5 cm (target 100 cm)

Pattern Multiple Alignment (6 sts + 1): 260 sts → 265 sts (diff: +5 sts)

Raw converted stitch count is 260 sts. Rounding up to match 6 × 44 + 1 gives 265 sts (difference of +5 sts, adding +1.9 cm of width).

How to adjust: Option 1: Cast on 265 sts and work 44 full repeats of 6 + 1 edge stitch (+1.9 cm ease). Option 2: Keep 259 sts (−1 st vs raw) and place any extra stitches into the plain underarm/selvedge seam allowances.

What people hate about the other tools

We read the reviews of the incumbents before writing this page. Every complaint below maps to a decision in the tool above.

When my stitch gauge matches but row gauge is off, simple calculators fail on raglan or sleeve shaping where row counts matter.
r/knitting (Reddit) · row vs stitch gauge split
In this toolConverts stitch and row gauge independently and recalculates vertical shaping intervals (e.g., decrease every X rows).
Calculators just give a new total stitch count without telling me the alternating k3, m1, k4, m1 sequence to increase or decrease evenly.
r/knitting (Reddit) · no even spacing formula
In this toolOutputs exact row instructions (e.g., K2, *M1, K4, M1, K3*) with flat selvedge protection or in-the-round spacing.
Too Loose / Lying Swatch — pure ratio multiplication breaks lace or cable stitch multiples and forces tedious manual size-jumping math.
r/knitting (Reddit) · breaks stitch multiples
In this toolRounds converted counts to your stitch multiple (X + Y) and identifies which existing pattern size fits your swatch.

One-line difference: Separates stitch & row gauge math, aligns pattern multiples, writes flat/round M1 intervals, and matches sweater sizes.
