About this landscape Poster 6mm flat-base triangle grid
Poster paper creates a large continuous grid for work that needs to be viewed, marked, or discussed from a distance. Each equilateral triangle has 6mm sides and a perpendicular height of approximately 5.2 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 588 x 436.5 mm, with 98 x 84 side-width and row-height intervals forming about 16,464 complete or edge-clipped triangular cells.

Why use Poster 6mm triangle paper?
A 6mm triangle grid balances drawing detail and writing room for general geometry, pattern design, maps, diagrams, and classroom activities.
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 6mm 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 Poster
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.
Poster vs Tabloid (11 x 17) 6mm triangle paper
Both formats preserve the same 6mm side length and flat-base starting phase. Choose Poster for wall charts, maps, displays, and large plans; choose Tabloid (11 x 17) when large handouts, plans, and presentation sheets better matches the printer or project.

Print Poster 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 Poster paper
Select an 18 x 24 inch custom or poster page size. Use a large-format printer or a print service that supports this sheet.
- 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 6mm.

FAQ
Answers specific to printing 6mm flat-base triangle grid paper on Poster.
What does 6mm triangle size mean?
The listed size is the length of every side of each equilateral triangle. Its perpendicular height is approximately 5.2 mm.
How many triangles fit on Poster paper?
This landscape template forms about 16,464 complete or edge-clipped triangular cells inside a centered 588 x 436.5 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 Poster paper, use Actual Size or 100% scale, and disable Fit to Page. Then verify that one horizontal side measures 6mm.
Should I use portrait or landscape Poster 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.
