A3 5mm Hex Grid Paper PDF
A3 portrait | 5mm hexes | Flat top
A3 landscape hex grid paper
This A3 landscape template uses pointy-top hexagons with a vertex at the top and bottom and 5mm edge lengths on a 297 x 420 mm page. Use it for vertical maps, alternate game layouts, and connected diagrams, or customize the colors and margins.
Template details
A3 provides twice the area of A4 while staying within the standard ISO A-series used for drawings, plans, and larger worksheets. Every hexagon has a 5mm edge, a 10 mm point-to-point diameter, and a 8.7 mm flat-to-flat diameter.
Pointy-top hexes have a vertex at the top and bottom and form staggered rows across the page. The centered grid area is approximately 394.0 x 272.5 mm and contains about 45 x 36 staggered hex positions.
A 5mm hex grid fits more cells on each sheet for compact maps, dense diagrams, fine game planning, and technical layouts.
Each cell has six evenly arranged neighbors, making the 5mm grid useful for movement, distance, terrain, encounters, and board-game layouts.
Use the repeated six-sided cells for molecular sketches, network diagrams, tiling studies, spatial planning, and designs built from connected units.
Pointy-top grids suit vertically organized maps, alternate game-board layouts, and routes that visually emphasize north-south movement. A3 is suited to engineering sketches and larger diagrams.
Both formats preserve the same 5mm edge length and pointy-top layout. Choose A3 for engineering sketches and larger diagrams; choose Tabloid (11 x 17) when large handouts, plans, and presentation sheets better matches the printer or project.
Open Tabloid (11 x 17) 5mm pointy-top hex paper →| Comparison | A3 | Tabloid (11 x 17) |
|---|---|---|
| Page size | 297 x 420 mm (11.69 x 16.54 in) | 11 x 17 in (279.4 x 431.8 mm) |

Use the PDF when the physical hex dimensions matter. The edge length and repeated geometry are preserved when the printer uses the correct paper and scale settings.
Load 297 x 420 mm paper and select A3 as the paper size in the print dialog.
Select Actual Size or 100% scale. Turn off Fit, Shrink, and Scale to Page options.
Keep the print dialog set to landscape so the grid is not rotated or reduced automatically.
Use a ruler to confirm that one straight side of a hexagon measures 5mm.

Answers specific to printing 5mm pointy-top hex grid paper on A3.
The listed size is the length of one straight hexagon edge. Each cell measures 10 mm from opposite points and approximately 8.7 mm between opposite flat sides.
This landscape template contains approximately 45 x 36 staggered hex positions inside a 394.0 x 272.5 mm centered grid area. Edge cells can be clipped by the rectangular border.
Choose the orientation that matches your map, game system, or diagram. Both provide six equal neighbors and identical cell dimensions; pointy top is simply a 30-degree rotation of flat top.
Select A3 paper, use Actual Size or 100% scale, and disable Fit to Page. Then verify that one edge measures 5mm.
Portrait is useful for tall maps and vertically organized diagrams. Landscape provides more horizontal room for wide maps, encounters, routes, and board layouts.
