Upload a reference
Choose a PNG, JPEG, WebP, BMP, or GIF image up to 20MB. The file is decoded locally on your device.
Drawing reference tool
Add a precise grid to any drawing reference
GridCrafter turns a photo or sketch into a customizable drawing grid without uploading the image to a server. Use square, triangular, or isometric grids, add coordinate labels or composition guides, and export the result for screen or print reference.
How to make a drawing grid
Customize the guide
Set the rows and columns, then adjust line color, thickness, opacity, grid type, labels, and composition overlays.
Export and draw
Download the finished reference as PNG, JPG, or PDF and copy the image one grid cell at a time.
Tools for proportion, transfer, and composition
Use one grid editor for simple reference transfer or more detailed composition studies.
Custom rows and columns
Choose from 1 to 50 rows and columns to match the complexity of your subject and drawing surface.
Multiple grid types
Switch between square, triangular, and isometric grids without re-uploading your reference.
Coordinate labels
Add A1-style labels to make it easier to find the same cell on your reference and drawing.
Composition overlays
Check rule of thirds, golden ratio, diagonals, and the center cross alongside the drawing grid.
Readable line controls
Adjust color, width, and opacity so grid lines remain visible without hiding important details.
PNG, JPG, and PDF
Export a high-resolution image for digital reference or a PDF that fits the guide onto a page.
How many grid squares should you use?
Start with fewer cells for a simple subject and add more cells when you need to measure small changes in shape. A 4×4 or 6×6 grid keeps the reference easy to read; portraits and detailed scenes often benefit from 8×8 or more. Use the same row-to-column relationship on the reference and drawing surface to preserve proportion.
Practical tip: enable coordinate labels before exporting, then label your paper or canvas the same way. Work cell by cell and compare the placement of edges, angles, and negative space rather than copying the entire image at once.
Private browser-based image processing
Your reference is processed with browser canvas tools and is not sent to GridCrafter. Closing or refreshing the page clears the working image. No account is required, and GridCrafter does not add a watermark to exported files.
Drawing grid maker FAQ
What is the grid method for drawing?
The grid method divides a reference and drawing surface into matching cells. You copy the shapes and angles inside one cell at a time, which makes proportion easier to measure.
Can I add a grid over a photo?
Yes. Upload a supported image, choose the number of rows and columns, adjust the line style, and export the photo with the grid included.
Does GridCrafter upload or store my image?
No. Image processing happens locally in your browser. The tool does not send the reference image to a GridCrafter server.
Which export format should I choose?
Use PNG for crisp digital reference, JPG for a smaller image file, or PDF when you want the guide fitted to a printable page.
