About this landscape A2 10mm flat-base triangle grid
A2 provides four times the area of A4 for technical drawings, classroom displays, and projects that need a large metric grid. Each equilateral triangle has 10mm sides and a perpendicular height of approximately 8.7 mm.
The flat-base option shifts the first diagonal row by half a triangle side, changing the phase visible at the upper grid edge. The centered grid area is approximately 570 x 398.4 mm, with 57 x 46 side-width and row-height intervals forming about 5,244 complete or edge-clipped triangular cells.

Why use A2 10mm triangle paper?
A 10mm triangle grid provides larger cells for bold constructions, labels, classroom demonstrations, quilting layouts, and designs that need more drawing room.
Geometry and tessellations
Use the three 60-degree line directions for equilateral triangles, rhombi, hexagons, symmetry exercises, transformations, and repeating geometric patterns.
Patterns, crafts, and maps
The 10mm triangles support quilting plans, bead and mosaic patterns, triangular maps, pixel-style designs, and technical sketches built from equal-sided units.
Flat Base layout on A2
The flat-base option shifts the first diagonal row by half a triangle side, changing the phase visible at the upper grid edge. The geometry stays the same, so choose the phase that makes the top of your drawing or pattern easiest to begin.
A2 vs A3 10mm triangle paper
Both formats preserve the same 10mm side length and flat-base starting phase. Choose A2 for large plans, displays, and technical drawings; choose A3 when engineering sketches and larger diagrams better matches the printer or project.

Print A2 triangle grid paper at the correct scale
Use the PDF when the physical triangle dimensions matter. The side length and 60-degree geometry are preserved when the printer uses the correct paper and scale settings.
- 1
Load A2 paper
Load 420 x 594 mm paper and select A2 in the print dialog. A large-format printer may be required.
- 2
Use Actual Size
Select Actual Size or 100% scale. Turn off Fit, Shrink, and Scale to Page options.
- 3
Match landscape orientation
Keep the print dialog set to landscape so the grid is not rotated or reduced automatically.
- 4
Check one triangle side
Use a ruler to confirm that one horizontal triangle side measures 10mm.

FAQ
Answers specific to printing 10mm flat-base triangle grid paper on A2.
What does 10mm triangle size mean?
The listed size is the length of every side of each equilateral triangle. Its perpendicular height is approximately 8.7 mm.
How many triangles fit on A2 paper?
This landscape template forms about 5,244 complete or edge-clipped triangular cells inside a centered 570 x 398.4 mm grid area.
What is the difference between point up and flat base?
Both options have identical triangle dimensions and line directions. Flat base shifts the first diagonal row by half a side, changing which phase begins at the upper edge of the grid.
Which print setting keeps the triangles true to size?
Select A2 paper, use Actual Size or 100% scale, and disable Fit to Page. Then verify that one horizontal side measures 10mm.
Should I use portrait or landscape A2 triangle paper?
Portrait works well for worksheets, vertical patterns, and notebook-style diagrams. Landscape provides more horizontal room for wide constructions, maps, quilts, and classroom demonstrations.
