等角方眼紙 vs 方眼紙：どちらを使う？

Graph paper is the default for math and plots. But if you draw boxes, rooms, product sketches, or any “3D-ish” diagram, isometric paper can be dramatically easier.

What graph paper is best at

Graph paper uses square grids, which makes it ideal for:

• coordinate graphs
• algebra and geometry work
• tables and clean alignment
• floor plans that don’t require perspective

If you need a classic US grid:

• 1/4 inch graph paper template

What isometric paper is best at

Isometric paper uses a triangular lattice that simulates 3D angles. It’s commonly used for:

• 3D boxes and product sketches
• piping diagrams
• game maps and level design
• engineering diagrams where depth matters

Which one should you choose?

• Choose graph paper if your work is mostly 2D, math-heavy, or needs square alignment.
• Choose isometric if you sketch objects in perspective or want 3D volume quickly.

Printing tip

For either grid, print at Actual Size / 100%. A small scaling change can distort angles and make drawings look “off”.
