Hexagonal Graph Paper: The Complete Hex Grid Guide

Hexagonal graph paper, often called "hex paper," features a tessellating pattern of regular hexagons that creates unique spatial relationships impossible with square grids. This specialized grid system is essential for board game design, wargaming, organic pattern creation, and situations requiring equal-distance relationships in six directions. This comprehensive guide explores the mathematics, applications, and techniques for working with hexagonal grids.

What is Hexagonal Graph Paper?

The Geometry of Hexagons

A regular hexagon has:

Six equal sides: All sides are the same length
Six equal angles: Each interior angle is 120°
Three axes of symmetry: Lines through opposite vertices
Perfect tessellation: Hexagons fit together with no gaps

Hex Orientations

Flat-Top Hexagons

Hexagons with flat edges at top and bottom:

Columns are vertical and offset
Rows are horizontal and aligned
Common in board games and wargames
Natural for north-south oriented maps

Pointy-Top Hexagons

Hexagons with vertices (points) at top and bottom:

Rows are horizontal and offset
Columns are vertical and aligned
Common in computer games and simulations
Natural for east-west oriented maps

💡 Choosing Orientation

The choice between flat-top and pointy-top is often based on the primary direction of movement in your application. For games with north-south movement, flat-top is easier. For east-west emphasis, pointy-top works better. Either can work for any application - it's mostly preference.

Why Hexagons?

Advantages Over Square Grids

Equal distances: All six neighbors are equidistant from center
Natural movement: More realistic representation of terrain and movement
Organic appearance: Less rigid and mechanical than squares
Optimal packing: Most efficient way to divide 2D space (found in nature)
Smooth curves: Better approximation of circular areas
No diagonal ambiguity: Six clear directions instead of four orthogonal plus diagonals

Disadvantages

More complex coordinate systems
Doesn't align with rectangular paper and screens naturally
Printing and cutting can be more difficult
Less intuitive for precise measurement
Mathematical calculations more complex than Cartesian coordinates

Applications of Hexagonal Graph Paper

Board Games and Wargaming

Strategy Games

Wargames: Classic hex-and-counter wargames use hexagonal boards for tactical combat
Civilization-style games: Territory control and expansion with realistic adjacency
Resource management: Tile-based games like Settlers of Catan use hex tiles
Miniature wargaming: Movement and range measurement in tabletop battles

Game Design Advantages

Consistent movement costs in all directions (no cheaper diagonal movement)
Each hex has exactly six neighbors for simple adjacency rules
Line-of-sight calculations are more natural
Range and area-of-effect calculations are simpler
Terrain features look more organic

Coordinate Systems for Hex Grids

Offset Coordinates

Column Offset (Flat-Top)

Similar to standard (x, y) coordinates:

Columns are numbered left to right
Rows are numbered top to bottom
Alternating columns are offset by half a row
Simple to understand but math can be complex

Row Offset (Pointy-Top)

Rows are numbered top to bottom
Columns are numbered left to right
Alternating rows are offset by half a column
Similar complexity to column offset

Axial (Trapezoidal) Coordinates

Uses two axes at 120° to each other:

More elegant for hex-specific mathematics
Distance calculations become simpler
Rotation and reflection are easier
Widely used in game development

Cube Coordinates

Three coordinates (x, y, z) with constraint x + y + z = 0:

Most mathematically elegant system
Distance is simple: (|Δx| + |Δy| + |Δz|) / 2
Rotations are simple 120° permutations
Redundancy (third coordinate derived) trades space for simplicity
Preferred by many game developers

Working with Hex Paper

Counting Distance

Adjacent Hexes

Distance of 1: Hexes that share an edge are distance 1 apart.

Longer Distances

To find distance between two hexes:

Count the minimum number of hex-to-hex moves needed
You can move through any of the six adjacent hexes each step
Find the shortest path (there may be multiple equally short paths)

📏 Distance Example

From hex A to hex B that's 3 hexes east and 2 hexes northeast: The distance is simply the maximum of the two directional components. In this case, max(3, 2) = 3. (This assumes cube coordinates; offset coordinates require more complex formulas.)

Drawing on Hex Paper

Filling Regions

Outline the boundary of your region
Fill hexes that are completely inside
Make decisions about edge hexes (include or exclude)
Use shading or colors to differentiate regions

Creating Circular Areas

Choose center hex
Count outward in all six directions for the radius
Fill all hexes within that distance
Result: Rough circle (more hexagonal the smaller the radius)

Line Drawing

Drawing lines on hex grids:

Straight lines follow a series of hexes in one of six directions
Diagonal lines step alternately between two of the six directions
Curves approximate smooth arcs better than square grids

Symbols and Annotations

Hex Center Marks

Small dots or symbols in hex centers for numbering
Icons representing terrain types or game elements
Resource markers or victory point indicators

Edge Markers

Walls or boundaries between hexes
Rivers or roads along hex edges
Connections or relationships between adjacent hexes

Junction points for networks

Game Design on Hex Grids

Board Game Creation

Map Design Process

Determine board size: Count hexes across and down
Plan key locations: Mark important strategic positions
Distribute terrain types: Create varied, balanced landscape
Add features: Resources, obstacles, special locations
Test movement: Verify accessibility and balance
Refine: Adjust based on playtesting

Terrain Types

Common game terrain on hex maps:

Plains/grassland: Normal movement, often default terrain
Forest: Defensive bonus, slower movement
Hills: Height advantage, visibility
Mountains: Impassable or very difficult terrain
Water: Impassable except by special units or crossing points
Desert: Harsh terrain with special rules
Urban: Cities, towns, roads

Movement Systems

Simple Movement

Each unit moves N hexes per turn
All adjacent hexes cost 1 movement point
Simple, fast, easy to understand

Terrain-Modified Movement

Different terrain costs different movement points
Example: Plains = 1, Forest = 2, Hills = 3
Adds strategic depth and terrain importance

Zone of Control

Units control/threaten adjacent hexes
Moving through enemy ZOC has consequences
Adds tactical positioning importance

Combat and Range

Adjacent Combat

Simplest: Units fight in hexes next to each other
Must be in one of the six adjacent hexes to attack

Ranged Combat

Count hex distance for range
Example: Range 3 weapon can hit any hex within 3 moves
Line of sight may be affected by terrain in intermediate hexes

Area Effects

Specify radius in hexes (e.g., "all hexes within 2 of target")
Creates roughly circular effect areas
Easy to visualize and calculate

Common Challenges and Solutions

❌ Challenge 1: Fitting Hexes to Rectangular Paper

Problem: Hexagonal grids don't align perfectly with rectangular paper edges.

Solution: Accept partial hexagons at edges, or plan dimensions to minimize waste. Use online hex grid generators that can optimize for standard paper sizes.

❌ Challenge 2: Complex Distance Calculations

Problem: Calculating distances isn't as simple as Pythagorean theorem.

Solution: Learn and use cube coordinate system. Distance formula becomes much simpler: max(|Δx|, |Δy|, |Δz|) or (|Δx| + |Δy| + |Δz|) / 2.

❌ Challenge 3: Orientation Confusion

Problem: Mixing flat-top and pointy-top in same project causes issues.

Solution: Choose one orientation at project start and stick with it. Note it clearly in documentation if working with others.

❌ Challenge 4: Unbalanced Game Maps

Problem: Starting positions have different advantages due to map layout.

Solution: Use rotational symmetry when designing competitive maps. Place mirrored resources and terrain for each player/faction.

Conclusion

Hexagonal graph paper offers unique advantages for game design, pattern creation, and spatial problem-solving. While more complex than square grids, hexagons provide more natural movement, equidistant neighbors, and organic appearances that make them ideal for many applications. From classic wargames to modern video games, from chemical benzene rings to decorative Islamic art, hexagonal grids are a versatile and powerful tool.

Start with simple projects to understand hex grid basics, experiment with different orientations and coordinate systems, and gradually tackle more complex designs. The initial learning curve is worth the effort - hexagonal grids unlock creative possibilities unavailable with square grids.
