About this landscape A3 10mm flat-top hex grid
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 10mm edge, a 20 mm point-to-point diameter, and a 17.3 mm flat-to-flat diameter.
Flat-top hexes have horizontal upper and lower edges and form staggered columns across the page. The centered grid area is approximately 380 x 259.8 mm and contains about 25 x 15 staggered hex positions.

Why use A3 10mm flat-top hex paper?
A 10mm hex grid provides larger cells for labels, tokens, classroom demonstrations, encounter maps, and layouts that need more writing room.
Maps and tabletop games
Each cell has six evenly arranged neighbors, making the 10mm grid useful for movement, distance, terrain, encounters, and board-game layouts.
Chemistry and technical diagrams
Use the repeated six-sided cells for molecular sketches, network diagrams, tiling studies, spatial planning, and designs built from connected units.
Flat Top layouts on A3
Flat-top grids are a familiar choice for wide maps, board-game layouts, and routes that visually emphasize east-west movement. A3 is suited to engineering sketches and larger diagrams.
A3 vs Tabloid (11 x 17) 10mm hex paper
Both formats preserve the same 10mm edge length and flat-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.

FAQ
Answers specific to printing 10mm flat-top hex grid paper on A3.
What does 10mm hex size mean?
The listed size is the length of one straight hexagon edge. Each cell measures 20 mm from opposite points and approximately 17.3 mm between opposite flat sides.
How many hexes fit on A3 paper?
This landscape template contains approximately 25 x 15 staggered hex positions inside a 380 x 259.8 mm centered grid area. Edge cells can be clipped by the rectangular border.
Should I use flat-top or pointy-top hexes?
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.
Which print setting keeps the hexes true to size?
Select A3 paper, use Actual Size or 100% scale, and disable Fit to Page. Then verify that one edge measures 10mm.
Should I use portrait or landscape A3 hex paper?
Portrait is useful for tall maps and vertically organized diagrams. Landscape provides more horizontal room for wide maps, encounters, routes, and board layouts.
