Answers for planning, sizing, and crocheting

A graphgan is a crocheted blanket that creates a picture using colored stitches arranged on a grid, similar to pixels in a digital image.

In Graphgan Studio, each cell represents one stitch in a specific color so the output speaks the language of crochet instead of generic pixel art.

Pick a path: upload a photo, or start from a blank chart and set rows and columns. Then choose your stitch method and size (or stitch counts for a blank chart).

Adjust the preview, save your project, export a printable file, or open the row-by-row Reader when you are ready to crochet.

Photos with clear subjects, stronger contrast, and simpler backgrounds usually convert more cleanly.

Busy photos can still work, but they often need a tighter crop, a larger blanket target, or more colors to hold onto the important detail.

No. You can use Graphgan Studio without signing in.

For most photo-based graphgans, Single Crochet Graphgan gives the strongest detail because the stitch footprint is closest to square.

C2C moves faster with a diagonal rhythm but trades away some photo detail. Custom Gauge Mode is best when you already have a swatch and know your stitches per inch and rows per inch.

Custom Gauge Mode lets you enter stitches per inch and rows per inch from your own swatch.

That gives Graphgan Studio a more personal starting point for the size estimate than an average default gauge.

Graphgan Studio will always label the blanket size as an estimate, not a guarantee.

Accuracy improves when you enter your real swatch gauge. Personal tension, yarn choice, hook size, blocking, borders, and gauge consistency can all change the final result.

Yes, especially for larger blankets. A 4 inch by 4 inch swatch with your chosen yarn and hook gives you the most trustworthy starting point.

Those numbers make the estimate more useful before you commit to a large pattern.

They are gentle warnings for patterns that may be too small for detail, too large to be practical, or mismatched with the target blanket size.

They are a trust feature, not a hard stop. The user keeps control, but the tool still speaks up when the settings look risky.

Open the Yarn & Size panel in the Pattern Generator. Pick your yarn weight category, then enter your skein's yardage (or grams) so the estimator knows how big one skein is.

Graphgan Studio breaks the chart down by color and shows roughly how many skeins of each color you'll need. The numbers are estimates — actual usage depends on your tension, hook size, and whether you weave in long tails or carry yarn across the back.

It is a calmer, dedicated crocheting mode that focuses on one row at a time.

It keeps your current row, direction, and completion progress in view without bringing the editor controls into your crocheting session.

No. Reader progress is saved to the project as you move from row to row.

When you come back, Graphgan Studio can return you to the first unfinished row.

Graphgan crochet usually alternates direction by row, so the reader shows whether you work left to right or right to left.

That direction indicator is one of the core reader elements because it reduces mistakes while you are actively crocheting.

When your project is in Corner-to-Corner mode, the Reader walks you through diagonals instead of rows. The status strip says 'Diag N' and the stitch counter reflects the current diagonal's length, which changes as you move through the chart.

You can switch between Row-by-Row and C2C from the menu (☰) under Reading mode. Switching resets your tracker to the start so you do not lose track of where you are.

Yes — the Reader has a mobile layout designed for crocheting with yarn in your other hand. Big Prev / Done / Next buttons live in thumb reach at the bottom, and you can collapse that whole bar with the Hide tab when you want more chart on screen.

Use one finger to pan around the chart when it is larger than your screen. Tap a cell to move the tracker there, or open the menu (☰) for jumps, reading mode, dark mode, and getting back to your projects list.

Yes. Open the menu (☰) and pick Dark under Appearance. Your preference is remembered the next time you open the Reader on the same device.

Projects are saved in this browser on the device where you created them.

If you clear browser storage or switch devices, those saved projects will not follow you yet.

You can export a printable PDF, a PNG version of the pattern, plain-text row instructions, or a CSV row breakdown.

The row-based exports follow the same launch Reader logic you see in the app, including row direction and grouped color runs.

The simplest way to share is to export the pattern file and send it however you like.

There is no built-in gallery or community feed in the app today.

Yes. Open Edit in the Pattern Generator toolbar, pick a color from the palette, and click any cell to repaint it.

The eyedropper copies the color from any existing cell, the fill bucket replaces a connected region of one color, and the eraser clears cells back to blank chart paper.

In the Edit panel, each palette color has its own row with a swatch, symbol, stitch count, and a hex value you can change directly.

Merge combines two close colors into one to simplify the palette. Trim crops away unused empty rows or columns around the edges of the chart.

Stamp lets you select a rectangular region of the chart and paste copies of it elsewhere — useful for repeating motifs, borders, or symmetrical designs.

After selecting, you can flip the stamp horizontally or vertically before placing it.

The toolbar has Undo and Redo buttons. On desktop, the usual keyboard shortcuts also work.

Each paint stroke, palette change, or stamp placement counts as one step in the history, so you can step back as far as you need.

Graphgan Studio accepts JPG, PNG, and WebP files up to 20 MB, with validation for unsupported files and broken images.

If an upload is rejected, double-check the file type, size, and that the image can open normally on your device.

Common fixes are increasing the color count, using a larger blanket target, cropping tighter around the subject, or picking a photo with better contrast.

Crochet grids have limited resolution, so some simplification is always part of the craft.

The first thing to check is gauge. Make sure you are entering stitches per inch and rows per inch in the unit you selected.

When default gauge is being used, Graphgan Studio will say so plainly because average numbers are useful starting points, not guarantees.
