Why Norwegian knitting charts knit up flatter than they look
On graph paper a star is a square: the 21-stitch Selbu star is 21 stitches wide and 21 rows tall. Knitting is not square, because a stitch is wider than a row is tall. At DK gauge (22 stitches and 30 rows per 10 cm) the same 21 by 21 square knits to about 9.5 cm wide and 7.0 cm tall (3.8 × 2.8 in), so it comes out 1.36 times as wide as it is tall. The eight points spread sideways while the height is compressed, which is why a star that looks square and even on paper looks flatter once it is knitted.
| Yarn | Gauge per 10 cm | 21-stitch Selbu star | Width ÷ height |
|---|
| Fingering | 28 sts × 36 rows | 7.5 × 5.8 cm (3.0 × 2.3 in) | 1.29× |
| DK | 22 sts × 30 rows | 9.5 × 7.0 cm (3.8 × 2.8 in) | 1.36× |
| Worsted | 18 sts × 24 rows | 11.7 × 8.8 cm (4.6 × 3.4 in) | 1.33× |
For a chart with as many rows as stitches, the width divided by the height is simply your rows per 10 cm divided by your stitches per 10 cm, so the closer those two numbers are, the rounder the star. Of the 3 gauges in the table, Fingering comes out roundest, at 1.29. The editor previews every chart at your own gauge with true stitch proportions, so you can see the stretch before you knit; keep the preview on while you change the width or the yarn, and print knitting graph paper at the same gauge if you want to draw beside it.
The free snowflake knitting charts take the other approach: their straight arms are drawn with extra rows, so all six arms knit to the same length. The Selbu stars here keep the traditional square chart, and the preview shows how wide each one will come out.
Cast-on counts for the Norwegian repeats
The 5 repeats are knitted in the round, so each one has to fit a whole number of times around the cast-on. Their widths are Star band (16 stitches), Lice (6 stitches), Small crosses (6 stitches), Cross and diamond border (8 stitches) and Spruce trees (8 stitches). The smallest count that holds all of them is their least common multiple, 48 stitches. The table takes a few common hat and mitten cast-on counts and shows how many whole repeats each one holds; a dash means that repeat does not fit that count.
| Cast on | Star band (16 sts) | Lice (6 sts) | Small crosses (6 sts) | Cross and diamond border (8 sts) | Spruce trees (8 sts) |
|---|
| 72 | — | ×12 | ×12 | ×9 | ×9 |
| 80 | ×5 | — | — | ×10 | ×10 |
| 88 | — | — | — | ×11 | ×11 |

A 96-stitch cast-on fits every repeat on this page: the table shows how many times each unit goes into it. If you are knitting only one of the repeats, any multiple of its own width will do; each repeat’s width is in the table above, so a narrower repeat can fit a much smaller count. The how to read a knitting chart guide explains how to keep the repeat lined up once the cast-on is right.
Floats and colors in Norwegian knitting charts
Every chart on this page uses no more than 2 colors in any row or round. The longest float is the longest run of one color in a row, or in a round for the repeats, counted across the edge of the repeat because the next repeat carries the same round on. The table gives that number for each chart.
The repeats are the easiest to knit: every one keeps its longest float to 5 stitches or fewer, so there is no need to catch the yarn. The 17-stitch Selbu star (7 stitches) and 21-stitch Selbu star (9 stitches) go past 5 stitches when knitted stranded; catch the carried yarn behind a stitch about every 5 stitches so it cannot snag on fingers or jewelry.
A float is measured one color at a time, not across the whole motif. The 21-stitch Selbu star is 21 stitches wide, yet its longest float is 9 stitches, because the petals are separated by background stitches instead of forming one solid block. That is why the number in the table is lower than the width of the star, and why a motif can be wide without needing a long carried strand in every row.
The colors themselves matter as much as the pattern. Put one light yarn and one dark yarn in each row, as these charts do, so the star and the lice dots stay readable at a distance. The charts use a main color for the background and one contrast color for the motif, and the PDF’s written instructions name them by letter, so the instructions still read the same after you swap in your own colors.
