Drop a photo or line drawing, lay a precise grid over it, set the finished real-world size to read off the exact cell dimensions, then export a PNG, a print-ready tiled PDF, or print straight across multiple A4 sheets.

Pages overlap by the glue margin and carry corner registration marks.
Anyone enlarging or transferring an image by hand — accurately, at a known scale.
Enlarge a reference onto canvas or a wall with the grid method. Set the finished size, read the exact cell dimensions, and tile across sheets for large murals.
Turn a picture into a numbered chart grid for cross-stitch, beading, or pixel patterns, with A1-style coordinates to keep your place.
Practise observational drawing with a clean grid overlay, mirror the image to check proportions, and print a faint underlay to trace.
No. The image is processed entirely in your browser using the Canvas API. It is never sent to any server, and closing the tab discards it.
It is pure arithmetic: cell width = finished width ÷ columns, cell height = finished height ÷ rows. The value shown matches a hand calculation exactly — for example, 300mm across 10 columns gives 30.0mm cells.
TraceGrid automatically splits the design across multiple pages, showing the total page count and the column × row layout. Each page includes a glue/overlap margin (5mm by default) and corner registration marks so you can align and tape the sheets.
A high-resolution PNG of the whole design, a print-ready tiled PDF with one paper sheet per page, or you can print directly from the browser. All three share the same exact grid math, so there is no drift between them.
No — TraceGrid only overlays the grid and handles sizing and tiling. To turn a photo into clean line art first, use TraceLine, then bring the result here.
Drop your image, choose the number of columns and rows (or a preset), and enter the finished width and height in mm or cm. TraceGrid shows the exact size of one cell so the proportions on your canvas, wall, or fabric stay true. Turn on "keep cells square" to auto-adjust the rows to your image's proportions.
Switch on numeric (1, 2, 3…) or A1-style numbering, placed inside the cells or as edge labels, to keep your place while transferring. Add a center cross or diagonals as alignment guides, mirror the image for mirror-copying, and lower the underlay opacity to print a faint base you can trace over.
When the finished size is bigger than your paper, TraceGrid tiles it automatically. Each sheet carries a glue/overlap margin and corner marks, and the panel tells you how many pages and the column × row layout. Download a tiled PDF for clean printing, export a high-resolution PNG, or print straight from the browser — every route uses the same precise measurements.
