Generate true 60° isometric grids
Isometric graph paper replaces two-point perspective with a true 60° triangular grid, so vertical and diagonal lines keep their real proportions no matter where they fall on the page. Architects use it to block out massing studies without foreshortening, product designers use it to mock up packaging in 3D by hand, and game artists rely on it to keep tile art aligned across a level. This generator draws three equally spaced line families — a vertical set plus two diagonals at ±30° from horizontal — directly in your browser, then renders a print-ready file at the exact spacing you choose. Switch between millimeters and inches, dial spacing from fine (3mm) to loose (50mm), and export a sheet that measures true to scale when printed at Actual Size.
Set isometric spacing and style
- Grid Spacing: Set the distance between lines from 3mm (fine detail) to 50mm (loose layout). The default of 10mm works well for general 3D sketching.
- Line Style: Pick Solid for clean technical drawings, or switch to Dashed or Dotted for lighter construction lines you can ink over later.
- Line Color and Weight: Choose a line color from the palette, with adjustable opacity, and a weight from Extra Thin (0.1mm) to Thick (0.8mm) to match your pen or printer.
- Paper and Margins: Select A4, A3, A5, or Letter in portrait or landscape, then set top, right, bottom, and left margins — or let the grid center automatically.
- Background: Swap the white background for a soft preset color if you prefer working on tinted paper.
- Preview: Zoom into the live preview to check spacing and contrast before committing to a print run.
- Export: Download as PDF for printing, SVG if you plan to trace or edit lines in Illustrator or Inkscape, or PNG for digital sketchbooks.
What makes this grid isometric
- True 60° Isometric Grid: All three line families are spaced identically, so every triangle in the lattice is equilateral — no skew, no approximation.
- Millimeter and Inch Precision: Switch units at any time; spacing, margins, and paper dimensions all recalculate automatically.
- Live Preview with Zoom: Check density and line contrast on screen before you export, so you don't waste paper on a test print.
- Vector and Raster Export: Save as PDF or SVG for sharp lines at any print size, or PNG when you need a raster image for an app.
3D sketching and design
- 3D Sketching: Rough out cubes, boxes, and product concepts with correct proportions along every axis.
- Architecture and Interiors: Block out room layouts, furniture placement, and massing studies before moving to CAD.
- Game and Pixel Art: Keep isometric tiles, maps, and level layouts aligned to a consistent 60° grid.
- Technical Illustration: Draw mechanical parts, exploded views, and assembly diagrams that read clearly in three dimensions.
Line weight for construction sketches
- Save Ink on Long Print Runs: A light gray line color (around #E5E7EB) at 0.1mm weight keeps the grid visible without soaking the page.
- Tighter Spacing for Fine Detail: Drop spacing to 3–5mm when sketching small objects or pixel-art-style scenes.
- Match Your Pen Width: If you're inking by hand, set line weight close to your pen's actual width so the guide grid doesn't compete with your linework.
- Edit Later in Vector Software: Export as SVG when you want to erase or reshape individual grid lines in Illustrator or Inkscape.
Line grid vs isometric dots
- Runs Entirely in Your Browser: The isometric grid renders locally as you adjust settings — nothing to install.
- Accurate at Any Scale: Spacing is calculated in real millimeters or inches, so the grid measures correctly once printed.
- Three Export Formats: Choose PDF for printing, SVG for editing, or PNG for pasting into digital notebooks and apps.
- Built for Precision Work: Fine-grained spacing, line weight, and color controls suit quick sketches and formal technical drawings alike.
