Crochet graph generator
Upload a photo and the editor builds a grid you can stitch in single crochet. Colors are matched to the DMC stranded-cotton list, so treat each number as a color label and substitute yarn.
What is a crochet graph
A crochet graph is a grid where one cell is one stitch. Single crochet stitches are wider than they are tall. This page uses a cell width of 1.25 times the cell height, so the chart on the screen has the proportions of single-crochet fabric. The stitch count still follows the photo: a square crop keeps the same number of stitches wide and high. You add or remove rows yourself when a swatch says the piece needs them.
Stitch gauge, hook size and yarn weight
Finished size is your gauge times the stitches on the chart. Hook size follows yarn weight. The ranges below are the Craft Yarn Council guidelines for single crochet over 4 inches, except lace. The council lists lace as double crochet, so that cell says so. They are a starting point. A swatch you make is the gauge that counts. Match the millimeter mark on the hook. US letter sizes differ by maker. On steel hooks a higher number is a smaller hook, which is the reverse of regular hooks.
| Yarn | Hook | Stitches per 4 in |
|---|---|---|
| Lace (0) | Steel 1.4–1.6 mm, or 2.25 mm | 32–42 double crochets in the council table, not single crochet. Measure a single-crochet swatch for lace. |
| Super fine (1) | 2.25–3.5 mm | 21–32 |
| Fine (2) | 3.5–4.5 mm | 16–20 |
| Light (3) | 4.5–5.5 mm | 12–17 |
| Medium / worsted (4) | 5.5–6.5 mm | 11–14 |
| Bulky (5) | 6.5–9 mm | 8–11 |
| Super bulky (6) | 9–15 mm | 7–9 |
| Jumbo (7) | 15 mm and larger | 6 or fewer |
You pick the hook and the yarn. The chart sets the grid and labels each color with a DMC number from the DMC color chart.
Single crochet vs C2C and tapestry
A single-crochet graph is worked in rows, one cell to one single crochet. That is the cell shape this page draws.
Tapestry crochet is also single crochet in rows. The unused color is carried inside the stitch, so the fabric is dense, and the graph is still one cell per single crochet. This page gives you that grid. You write the color changes from the symbols as you stitch the row.
Corner-to-corner (C2C) uses a block, often a small cluster of double crochets, worked on the diagonal from one corner. A C2C block is closer to square than a single crochet stitch, and the written pattern increases to the middle, then decreases. The 1.25 cell width matches single crochet, so read a C2C project from your own block gauge and use this grid as the picture.
How the grid converts to size
The inch line in the editor uses the cross-stitch fabric count. A 140-stitch width on 14-count Aida is 10 inches of fabric. Those same 140 stitches in yarn might be a coaster or a blanket, depending on the hook and the yarn. Measure a single-crochet swatch. Divide 4 inches by your stitch count and, separately, by your row count, because width and height differ. Multiply those two numbers by the stitches and rows on the chart.
Buy yarn from the swatch. The skein line on a chart assumes 2-strand cross stitch on 14-count Aida, about one skein per 2,000 stitches. It is a floss estimate. Fabric inches for cross stitch, including that 140-stitch example, are on the cross stitch calculator. For a cross-stitch chart from a photo, use photo to pattern.
