Draw a Fantasy Map: Coastlines, Terrain Symbols, and Legend

Object Drawing Lessons

A fantasy map becomes useful when a reader can tell water from land, hills from mountains, and forest from swamp without guessing. This lesson teaches a simple drawing convention: coastlines as closed contours, terrain as repeated symbols placed inside regions, and a legend that pairs each symbol with a short label. You will plan a map frame, draw a coastline contour guide, choose terrain symbols, and build a legend box. The convention is explicit so that valid alternatives, such as stippled desert versus cross-hatched desert, can still be checked against your own legend. All measurements are hypothetical examples; measure your actual paper and tools before drawing.

Plan the frame and coastline contour guide

Start with a rectangular map frame. A hypothetical example is a 15 cm by 20 cm frame on A4 paper, leaving a 2 cm margin. Measure your own paper and draw the frame lightly in pencil. The frame is the boundary of the map, not a coastline.

Inside the frame, sketch a coastline contour guide: one closed line that separates water from land. Keep the line continuous and avoid crossing it. A simple check is to trace the line with your finger; if you lift your finger, the coastline is broken. Leave space outside the coastline for water and inside for land.

Decide where the sea meets the frame. You may let water touch the frame edge, but the coastline itself should remain a closed contour within the frame or clearly continue beyond it. For a self-contained map, keep the coastline closed inside the frame so the legend can describe all regions.

1. Measure your paper and draw a light rectangular frame.
2. Sketch one closed coastline contour inside the frame.
3. Check that the coastline does not cross itself or stop abruptly.
4. Mark a small north arrow outside the frame if you want orientation.

Choose and repeat terrain symbols

Terrain symbols are small, repeatable marks placed inside land regions. Define each symbol in words before drawing it. For example: mountain = a triangle with a short base line; hill = a small arc; forest = three short vertical strokes with a horizontal base; swamp = two short horizontal dashes with a dot between them; desert = small dots spaced apart. These are conventions, not universal standards.

Place symbols in clusters rather than single marks. A mountain range is a row of triangles; a forest is a group of tree symbols. Keep symbol size consistent within a region. A check is to compare three symbols from the same region; they should look like the same mark repeated.

Do not mix water symbols on land or land symbols in water. If a symbol appears in both, your legend must explain the difference. For clarity, keep one symbol per terrain type and use spacing to show density.

1. Write a one-line definition for each terrain symbol.
2. Draw a small test row of each symbol outside the frame.
3. Place clusters of symbols inside the land region.
4. Check that each symbol matches its written definition.

Build the legend box

The legend box is a rectangle, hypothetically 4 cm by 6 cm, placed in a corner outside the map frame. Divide it into rows. Each row contains one symbol and a short label, such as Mountain, Forest, Swamp, Desert, or Water. The label must match the symbol you actually drew.

Order the legend rows by importance or by terrain type. Keep labels to one or two words. A check is to cover the map, read only the legend, and ask whether you could redraw each symbol from its label. If not, revise the label or symbol.

The legend is part of the map, not decoration. Every terrain symbol used on the map should appear in the legend, and every legend entry should appear on the map at least once. This one-to-one check prevents unused or missing symbols.

1. Draw a legend box outside the map frame.
2. List each terrain symbol and its short label in a row.
3. Check that every map symbol appears in the legend.
4. Check that every legend entry appears on the map.

Review the map as a reader

Read your map from the legend outward. Pick a legend entry, find its symbol on the map, and confirm the symbol is inside a land region and not in water. Repeat for each entry. This is a simple consistency check.

Check coastline continuity again after adding symbols. Terrain symbols should not touch or cross the coastline unless your convention says they do. A safe convention is to keep symbols at least one symbol-width away from the coastline.

Finally, check scale and units. If you write a scale bar, label it with a hypothetical unit such as one centimetre equals ten kilometres, and measure the bar with a ruler. Do not claim a standard you have not measured.

1. Pick each legend entry and locate its symbol on the map.
2. Confirm symbols are inside land regions and away from the coastline.
3. Measure any scale bar with a ruler and label the unit.
4. Erase construction lines and keep the final map clean.

Worked example

A map frame is 15 cm by 20 cm. The legend box is 4 cm by 6 cm and sits outside the frame. The map uses four terrain symbols: mountain, forest, swamp, and desert. The coastline is one closed contour. Check the legend-to-map consistency and the frame area.

Four practice exercises

Common mistakes

• Drawing the coastline as a broken or open line. Trace the coastline with your finger; if it stops, redraw it as one closed contour inside the frame.
• Using a terrain symbol on the map that is missing from the legend. List every symbol used, then add a legend row for each missing symbol or remove the symbol from the map.
• Placing forest symbols in the water region. Check each symbol against the coastline; move land symbols inside the land region and water symbols outside it.
• Making symbols inconsistent in size within one region. Draw a test row of the symbol and compare three examples; redraw outliers to match the test row.

Self-check rubric

• Coastline is a continuous closed contour inside the frame or clearly continued beyond it.
• At least three terrain symbols are defined in words and repeated in clusters.
• Every terrain symbol on the map appears in the legend, and every legend entry appears on the map.
• Legend labels are short and match the drawn symbols.
• Symbols are placed inside the correct region (land or water) according to the stated convention.
• Any scale bar is measured with a ruler and labelled with a hypothetical unit.
• Valid alternatives are accepted if the legend defines the symbol actually used.
