Printable Isometric Graph Paper
Choose 5mm for detailed work or 10mm for larger drawings, then select portrait or landscape.
Print at Actual Size or 100% so the prepared measurements stay accurate.
What is isometric graph paper?
Isometric graph paper combines vertical guides with diagonal lines at 30 degrees, giving you three equal drawing directions for width, height, and depth. It makes three-dimensional forms easier to sketch with straight, parallel edges and consistent proportions.
Use it for cubes, product concepts, furniture, mechanical parts, room layouts, voxel art, and isometric game maps. Choose 5mm spacing when the drawing needs detail, or 10mm spacing for larger shapes, labels, and quick classroom sketches.
Which paper size should I choose?
Check the size printed on your paper pack or shown in the printer tray. A4 is standard in most countries, while US Letter is standard in the United States and Canada. Choose a larger size only when your printer or print service supports it.

Which isometric grid spacing should you choose?
The choices below explain what changes and when each option is useful. Make the actual selection in the download panel at the top of the page.
5mm
A 5mm isometric grid supports detailed 3D drawing, compact technical sketches, product concepts, geometric constructions, and designs that need precise alignment.
10mm
A 10mm isometric grid creates larger triangular cells for classroom demonstrations, quick 3D concepts, simple block forms, labels, and presentation-friendly drawings.
What is isometric graph paper used for?
Technical and product sketches
Keep parallel edges aligned while drawing components, furniture, packaging, mechanisms, and product concepts.
3D block forms
Build cubes, voxel scenes, room layouts, geometric solids, and exploded diagrams on three equal drawing axes.
Maps and game design
Plan isometric rooms, terrain, routes, and game maps while keeping repeated forms consistent.
Frequently asked questions
Answers about choosing, downloading, customizing, and printing this paper.
What angles are used on isometric graph paper?
The grid uses one vertical direction and two diagonal directions at 30 degrees to the horizontal. Together they form equilateral triangles.
Should I choose 5mm or 10mm isometric paper?
Choose 5mm for smaller objects and technical detail. Choose 10mm for quick concepts, classroom work, larger labels, and presentation drawings.
Which file format should I download?
Choose PDF when you want to print at an accurate physical size. Use PNG for notes, worksheets, and image-based documents. Choose SVG when you need an editable vector file for a drawing or design application.
Should I choose portrait or landscape?
Portrait gives you more vertical working room for worksheets, notes, and tall diagrams. Landscape gives you more horizontal room for charts, maps, tables, timelines, and wide drawings. The prepared measurements stay the same in either orientation when you print at 100%.
Why did the paper print at the wrong size?
The print dialog probably scaled the page. Print the PDF at Actual Size or 100%, and turn off Fit to Page, Shrink, and other automatic scaling options. The paper size selected in the print dialog must also match the file you downloaded.
Can I customize this paper?
Yes. Open the isometric grid generator when the ready-made sizes or styles on this page do not match your project.
