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.
