Fantasy Map Symbols and Legends: What Every Icon Means and When to Use It

Pick up any published fantasy map and you can read it without instructions. Little triangles are mountains. Clusters of lollipops are forest. A dot with a ring around it is a city, and a bigger dot is a bigger city. Nobody taught you this. You absorbed it from a hundred maps in the front of a hundred paperbacks.

That shared vocabulary is the whole point of map symbols. It is also why a map that invents its own icons, or uses the standard ones inconsistently, feels subtly wrong even to a reader who could never say why. This guide walks through the symbols you will actually use, where the conventions came from, and the short list of rules that keep a legend useful instead of decorative.

Legend, key or cartouche?

People use these words interchangeably. They are not the same thing. A legend (or key, the terms mean the same thing) is a box that pairs each symbol on the map with its meaning. Triangle: mountain. Dashed line: road. It exists purely for the reader’s benefit and should be as short as you can make it.

A cartouche is the decorative panel that holds the map’s title, and sometimes the scale, the mapmaker’s name, or a dedication. On old charts it is often a riot of scrollwork and drapery. On a fantasy map it is usually the ornate banner carrying the name of the world. It tells the reader what they are looking at, not how to read it. Plenty of maps have a cartouche and no legend at all, because the symbols are self-explanatory. That is a perfectly good decision, and we will come back to it.

Mountains and hills

Mountains are the symbol with the most variation, because cartographers have spent five centuries arguing about how to draw a lump of rock on a flat page.

The molehill range. The oldest and still the most common fantasy convention: a row of little profile peaks, drawn as if you were standing to the south looking north at them, shaded on one side. Tolkien’s maps of Middle-earth use this style, and so does almost every paperback map since. Its great strength is that the reader instantly understands “mountains here” and the drawing never obscures the land behind it. Its weakness is that it says nothing about real height or shape.

Hachures. Short strokes drawn down the slope, dense where the ground is steep and sparse where it is gentle. Common on eighteenth and nineteenth century military maps, and a good fit for the ink style if you want something that feels surveyed rather than sketched. Hillshade. Rendering the terrain as if lit from one corner, usually the upper left, so slopes facing the light are pale and slopes facing away are dark. Modern atlases use this because it shows the actual form of the land. The generator does this automatically underneath its profile mountains, which is why the ranges look like they have weight rather than being stamped onto the page.

Whichever you choose, draw your hills as smaller, lower-contrast versions of the same thing. If your mountains are profile peaks and your hills are contour blobs, the map looks like two people drew it.

Forests, swamps and deserts

The tree cluster. Forest is drawn as a scatter of small tree glyphs, round-headed for deciduous woods and pointed for pine. The convention worth knowing is that the trees are drawn far smaller than scale. A forest that is fifty miles across gets a few dozen trees, not fifty miles of them. The scatter tells the reader “forest here” and the density hints at how thick it is. On the verdant style the generator fills these in as solid green woodland with individual trees on top, which reads more like a storybook illustration.

Marsh tufts. Swamps and fens are drawn as short horizontal dashes with a few grass tufts sticking up, often with a faint water line beneath. It is one of the most recognisable symbols on any map, and one of the most under-used on fantasy ones. A marsh at a river mouth, between two kingdoms, is worth three paragraphs of political backstory.

Stippling. Deserts and dunes are shown as fields of tiny dots, sometimes with curved dune crests. Sand-coloured tint does most of the work; the stipple adds texture.

Water

Rivers are lines that get thicker toward the sea, lakes are enclosed shapes in the water colour, and the ocean is whatever your paper is not. That much is obvious. The details are where maps go wrong, and rivers in particular deserve their own post: see 7 river mistakes that break your fantasy map.

Sea monsters, and the dragons that were not there. You have heard that old maps marked unknown waters with the words “here be dragons.” It is a lovely story and it is almost entirely false. The Latin phrase HC SVNT DRACONES appears on the Hunt-Lenox Globe of around 1510, now in the New York Public Library, and on the closely related ostrich egg globe, and on essentially nothing else. Medieval mapmakers did draw sea monsters, lavishly, but as illustrations rather than warnings, and the phrase they actually used for unknown territory was HIC SVNT LEONES, “here are lions.” So put a serpent in your ocean if you like the look of it. Just know that you are following a Renaissance engraver’s taste for decoration, not a lost tradition of cartographic warning signs.

Roads, borders and settlements

Roads. Solid lines for major roads, dashed for tracks and trails, with the dash getting shorter and fainter as the route gets rougher. Roads should connect settlements to each other and go somewhere; a road that ends in a forest is a plot point, not a symbol. In the verdant style the generator draws dashed nearest-neighbour roads between towns automatically.

Borders. Political boundaries are almost always drawn as dashed or dot-dash lines, sometimes reinforced with a faint colour tint on one side. The dashes signal “this line is an agreement, not a feature.” A solid border line reads as a wall or a cliff. Colour tinting whole territories is the atlas approach and works well when you have more than three or four realms. The generator names kingdoms and places the names over their territory, but it does not draw border lines between them. That is a deliberate omission: borders are the thing your story is most likely to change, and they are a two-minute job with a dashed pen once you have exported the SVG.

Settlements. The standard ladder runs village, town, city, capital, and each tier is drawn as a step up from the last: a plain dot, a dot with a ring, a larger ringed dot, and then something special for the capital, typically a small castle, tower or crown. The rule that matters is restraint at the top. One capital per kingdom. A handful of cities. As many villages as you like. The city placement post covers where they should go; this is only about how they should look.

Ruins and dungeons get a broken tower, a cracked column or a cave mouth. These are the symbols that make a map feel like it has a past. Use them sparingly and never over-explain the label. “The Sunken Halls” is enough.

The furniture: compass, scale and frame

Three elements sit outside the geography and tell the reader how to use it.

The compass rose. It began life as a wind rose. Greek and Roman sailors named the winds rather than the directions, and the eight major winds, eight half-winds and sixteen quarter-winds give the classical rose its 32 points. The device moved onto sailing charts with the Mediterranean portolan charts of the 1300s, and the Catalan Atlas of 1375 is usually credited with the first true compass rose on a map. The fleur-de-lis marking north is a Portuguese and Italian habit from the 1500s, and the small cross that sometimes marks east points toward Jerusalem. On a fantasy map, one elaborate rose beats a dozen small flourishes.

The scale bar is a ruled bar marked in miles, leagues or whatever unit your world uses. It is the least glamorous item on the map and the one that most often gets forgotten, and its absence is the fastest way to turn a map from a place into a picture. Getting the scale right in the first place is its own subject; the fantasy map scale post works through it. The generator draws one in the corner by default and lets you toggle it off from the Advanced panel if your map is deliberately unscaled.

The neatline is the border around the whole map. On old charts it often carries latitude ticks; on fantasy maps it is decoration, but it does real work: it turns a drawing into an object, the way a frame turns a canvas into a painting.

Symbol	Convention	Watch for
Mountain	Profile peaks, shaded one side	Hills drawn in a different style
Forest	Scattered tree glyphs, undersized	Trees marching in neat rows
Marsh	Horizontal dashes with tufts	Confusing it with grassland
Desert	Stippling on a sand tint	Reusing stipple for beaches
River	Line thickening toward the sea	Forks pointing downstream
Road	Solid major, dashed minor	Roads that lead nowhere
Border	Dashed or dot-dash line	Solid lines that read as walls
Village	Small dot	Too many labels
City	Ringed dot	Too many of them
Capital	Castle, tower or crown	More than one per realm
Ruin	Broken tower or column	Over-explaining the label
Compass rose	North up, fleur-de-lis optional	Competing with the title
Scale bar	Ruled bar with a unit	Leaving it off entirely

What the generator draws for you

If you are working from a generated map rather than a blank page, most of the furniture is already in place.

Drawn automatically: the title cartouche, the compass rose, the scale bar, the frame, hillshaded terrain with profile mountains (snow-capped at altitude), forest clusters, rivers, city dots with placed labels, and sea and kingdom names. In the verdant style you also get house clusters for each town, a tower for the capital, dashed roads, and a few ships and a sea serpent offshore. The frame, title, compass, scale bar and labels can each be toggled off from the Advanced panel.

Added by hand: the Add menu above the map places four kinds of element wherever you click, a mountain, a tree, a castle or a town. Each one can be resized or deleted after placement, and all of them use the same glyphs as the generated features, so your additions match the map instead of floating on top of it. The same menu adds a free text label, which is how you mark a ruin, a battlefield or a border town the engine did not think of. Anything the generator does not offer, such as marsh tufts or a dashed border, you add after export: the SVG download opens in Inkscape or Illustrator with every feature on its own path.

The main generator is the quickest way to see all of this on a real map. Roll a few seeds and watch how the same symbol set reads differently across the five art styles; the art styles post explains what each one is imitating.

Four rules for a legend that helps

Fewer symbol types is better. A map with six symbols is easier to read than a map with twenty, and almost every map can get by on six. Before you add a special icon for “haunted forest,” ask whether an ordinary forest with a well-chosen name would do the same work.

Consistency beats detail. A crudely drawn mountain used identically forty times is more convincing than forty beautifully drawn mountains that are each a little different. The reader’s eye is pattern-matching; give it a pattern.

Everything on the map appears in the key, and nothing else. If you use a symbol, it goes in the legend. If it is in the legend, it is somewhere on the map. A legend that lists symbols the map does not contain is a common and slightly embarrassing tell of a template that was never edited.

A legend only earns its place when the reader cannot guess. If your symbols are the standard ones described above, most readers will never look at the key, and a paperback map is better off spending the space on a larger cartouche. Add a legend when you have invented something (a symbol for ley lines, for portals, for the places the dragon has burned) or when the map is a working document for a game table and precision matters more than beauty.

The test is simple. Cover the legend with your thumb and hand the map to someone who has never seen it. If they can tell you where the mountains, the forests, the cities and the capital are, your symbols are doing their job. If they have to lift your thumb, that is what the legend is for.
