Crochet chart maker — editable rows, rounds & vector PDF
Place crochet symbols into alternating rows or outward-facing circular rounds, then edit the chart and its counting assumptions. Real vector downloads include a symbol key and count report. Your work stays in the browser, with an editable JSON project you can save and reopen.
Crochet Symbol Studio
US crochet terms. The arithmetic checker uses declared working units; it does not certify a pattern or infer attachment points.
Supported scope: Up to 16 rows/rounds, 120 stitch symbols per row and 1,200 symbols overall. Repeats support three nested groups; imports are this tool’s UTF-8 JSON projects up to 100 KB. · Supported codes: ch, slst, sc, hdc, dc, tr, inc, inc3, dec, dec3, dcinc, dcdec, sk. No arbitrary pattern parsing, image tracing, freehand placement, Tunisian stitches, lace-space inference or fabric simulation. · Starting chains and joins are explicit annotations. Counted starting chains occupy one base unit in this model. Each working ch creates one unit; chain spaces and attachment targets need human review. · Chart titles use 1–80 printable ASCII characters for the standard PDF font. PDF export stops after 45 seconds; reset/cancel terminates the worker. No automatic online or browser-storage saving.

Does a balanced count mean my pattern is correct?
No. The checker compares consumed base units with the previous row’s produced units under your selected assumptions. It also compares optional expected outputs. It does not infer attachment points, chain spaces, yarn paths, stitch height, gauge or shaping. A balanced chart can still be impossible or produce an unintended fabric. Make a swatch and inspect the actual construction.
Are these US or UK stitch names?
US names are used throughout. For example, sc means US single crochet and dc means US double crochet. inc/dec use single crochet; dcinc/dcdec use double crochet. The downloaded key defines every used symbol. Skip and TC labels are editor annotations, not a claim of universal notation.
How are turning chains and joining slip stitches counted?
A starting chain is recorded separately from working ch symbols. If marked counted, the entire starting chain makes one unit and occupies one previous base position; otherwise it contributes zero. A join annotation contributes zero. A slst inside the sequence is a working slip stitch and uses one base / makes one unit. Set these assumptions to match the pattern you are planning.
Can it read a pattern PDF or turn a photograph into crochet instructions?
No. Enter the supported stitch codes and bounded repeats, or import an editable project JSON created by this tool. The program does not parse arbitrary written patterns, trace images, infer lace attachment graphs or simulate fabric. This is a symbol-chart editor with explicit arithmetic checks.
Can I save and reopen a chart?
Yes. Download the editable project JSON or complete ZIP. Import that JSON to reconstruct the chart, stitch codes, colors, layout and counting settings. Work is not automatically saved in browser storage or on a server. After editing, prepare fresh exports in the editor; the initial downloads still reflect the original chart.
Are the PDF and SVG real vector files?
Yes. Lines, curves and text are written as vectors. PDF includes an overview, detail tiles when the chart would otherwise be too small, and the symbol key/count report. SVG includes the chart and key in one scalable document. Neither export is a screenshot or a renamed text file.

Reference for common stitch-symbol conventions and the importance of reading the pattern key. This tool draws its own geometry; it does not copy or embed the Council’s chart artwork.

US terminology and US/UK naming differences. The tool uses an explicit supported code subset plus clearly labeled editor annotations.

Background on rows, rounds, increases, decreases and pattern-dependent turning-chain interpretation. Arithmetic alone does not establish a complete crochet pattern.
