Export Isometric Grid Paper in Line or Dot Mode to PDF

When you need to sketch a product, building, or pixel-art sprite with consistent 60-degree angles, isometric grid paper gives you the three-direction guide you need without reaching for a set square. Lineum lets you switch between a full line grid and a dot grid (intersection points only), set the spacing in millimeters, and optionally highlight a major line at a regular interval for easy scale reading. Dot mode keeps the page quiet so your hand-drawn lines stand out once you ink over the lattice points. No account required — export and print a fresh sheet whenever you need one.

Use cases

  • Roughing out 3D illustrations and isometric technical drawings. Follow the three-direction lines to draw cube edges and building outlines that line up naturally — no ruler needed for consistent 60-degree angles across the whole sketch.
  • Product design and architectural exterior sketches. An isometric grid in landscape orientation gives wide space for objects that spread horizontally. Set a major line interval to read proportions quickly and keep parts at consistent scale relative to one another.
  • Designing pixel art and isometric sprites. In dot mode each point is an isometric lattice vertex. Build characters, maps, or tile sets by treating each dot as a pixel reference, then ink or digitize the final design.
  • Pattern design for puzzles, tiles, and crafts. The isometric lattice is a natural base for arranging hexagons, rhombuses, and triangular tiles in a repeat pattern. Use it for paper craft templates, embroidery designs, or the unfolded net of a geometric solid.

Tips

  • The default is 5 mm spacing in line mode. Try 3–4 mm for detailed illustrations and 7–10 mm for larger isometric drawings.
  • Switch to dot mode (isoMode = dot) to show only the lattice intersection points — great for tracing pixel art or designing patterns where you don't want lines in the way.
  • Set isoMajorEvery to highlight a major line every N lines. This breaks the grid into measurable blocks so you can read proportions at a glance.
  • Landscape orientation gives you a wider canvas for scenes and objects that spread horizontally, such as buildings or vehicles.
  • Print at 100% scale with minimum margins so the spacing comes out at the exact millimeters you set.

FAQ

What is isometric grid paper?
Isometric grid paper is printed with three sets of parallel lines at 60-degree angles, forming a triangular lattice. It lets you draw objects in isometric projection — a 3D representation where all three axes are at equal angles — without a set square or ruler. Line mode shows the full grid; dot mode shows only the intersection points.
What's the difference between line mode and dot mode?
Line mode draws three sets of parallel lines so the full isometric grid is visible. Dot mode places a point only at each intersection, keeping the page clean so your own drawing stands out.
What grid spacing is standard for isometric drawing?
5 mm is the most common standard. Use 3 mm for detailed artwork and 7–10 mm for larger architectural or engineering sketches.
Can I use this for isometric projection practice?
Yes. The three-direction guide lines make it easy to draw the edges of cubes, prisms, and other solids in correct isometric proportion.
Can I use it for pixel art or sprite design?
Yes. Switch to dot mode and each dot marks an isometric lattice point. Use it as a grid reference to design isometric characters, tiles, or maps dot by dot.
