Guides / Graph paper

Online graph paper drawing

A subtle grid makes rough diagrams and layout sketches easier to keep aligned. PlainCanvas gives the workspace a light graph-paper feel while still exporting a clean PNG drawing.

Use the grid as a guide

The grid helps with spacing, but it should not control every mark. Use it to keep boxes, arrows, and rough layout blocks readable. For exact measurements, use a dedicated CAD or diagramming tool.

Best uses for a grid canvas

• Simple flowcharts and process maps.
• Website section planning and wireframes.
• Classroom diagrams and study notes.
• Room or event layout sketches.

Exporting grid-based sketches

Use thicker lines if the image will be resized. Choose a white background for a note-like result or transparent when the drawing will sit over another design.
