Map with Legend Maker

Free map annotator with markers, region fills, and a custom auto-generating legend. Pick any of eight base maps — World, United States, every continent — drop markers in five shapes, fill regions with categorical colors, and the legend builds itself as you go. No sign-up, no watermark, no Photoshop.

Add a legend to any map — automatically

Most online map tools force a choice: either you accept a rigid auto-generated legend bound to a chart type, or you build the legend by hand in a separate window and align it manually in Photoshop. Map with Legend Maker takes a different path. The legend is a real cartographic legend — a corner box with a title, an icon-and-label row for every category — but it builds itself from the markers and region fills you place on the map.

Define a marker category called "Capital" with a star shape and a yellow color, drop one star anywhere on the map, and the legend instantly shows a yellow star labelled "Capital". Drop the second capital — legend doesn\u2019t change (the row already exists). Add a region category called "NATO members" in blue, fill four countries — the legend grows a blue rectangle labelled "NATO members". Delete a category — the row vanishes. The legend is always a faithful summary of what is actually on the map.

How to make a map with a legend

Six steps from blank base map to a finished map ready for slide, print, or web embed.

1. Pick a base map. Choose World, United States, or any of the six continents. The base map sets the geographic frame and the regions you can fill. Switch base maps freely from the toolbar — every basemap shares the same legend builder.
2. Define your legend categories. Open the sidebar and add marker categories (with shape and color) and region categories (with color). Each category is a row in the legend; the legend updates the moment you create one.
3. Drop markers on the map. Pick a marker category and switch to Add-marker mode. Tap any point on the map to drop a marker at that spot. Add a caption to label the marker on the map; the marker still appears in the legend with its category icon.
4. Fill regions with category colors. Pick a region category and switch to Fill-region mode. Tap any country, US state, or continent feature to fill it with the category color. Tap again to clear. Use this for political alliances, sales territories, hiking zones, election results, or any region-grouped data.
5. Title the map and position the legend. Add a map title and subtitle in the sidebar (rendered above the map on every export). Choose where the legend sits — top-right, top-left, bottom-right, bottom-left, or hidden. The legend itself stays anchored to its corner as you zoom and pan.
6. Export or share. Download as PNG (high-resolution image), SVG (vector graphic editable in Illustrator or Inkscape), or PDF (print-ready, US Letter or A4). Or copy a shareable URL that encodes the entire map state.

Three building blocks: regions, markers, and the legend

Every map made with this tool is built from three primitives. Knowing how they compose is the difference between a flat-looking map and a publication-grade one.

Region fills

Each country, US state, or continent feature on the base map is a fill target. Click a region (with the Fill-region tool active and a region category chosen) and the region takes the category color. Use this for political alliances, election results, sales territories, national parks, climate zones — any data where the geographic unit itself is the data point. Region fills are the lowest-effort, highest-impact annotation: one click per region, instant visual coverage.

Markers (with shape, color, and caption)

Markers are point annotations. Each marker has a category (which determines shape and color) and an optional caption (a short text label rendered next to the pin). Use markers for cities, peaks, battles, observation points, branch offices, anything that has a precise geographic location rather than covering an area. Five shapes follow cartographic convention — see the next section. Markers can be added in seconds: pick category, tap the map, repeat.

The legend (auto-generated)

The legend is the corner box that explains the symbols. Every used category — every category with at least one marker placed or one region filled — becomes a legend row with the icon on the left and the label on the right. Empty categories don\u2019t show; deleted ones vanish instantly. The legend is anchored to a corner of the map and stays put as you zoom and pan, so it never floats away from where the eye expects it.

Map legend examples by use case

Seven recurring patterns we see in the analytics. Each one combines region fills + markers + captions in a different ratio. The tool handles all of them with the same UI.

What makes a great map legend

The legend is the most-skipped element of a map but it determines whether the rest of the map is readable. A few principles, distilled from cartographic style guides used at the US Geological Survey, the British Ordnance Survey, and the New York Times graphics desk:

Order matters

List legend rows in the order the eye will encounter them on the map, or in semantic order (capitals before secondary cities, NATO before non-aligned, primary roads before secondary). Don\u2019t leave the order to category-creation timing — reorder if needed. Map with Legend renders categories in the order they were defined; rename and re-add to control the sequence.

Symbol consistency

Every symbol in the legend must appear at least once on the map (Map with Legend enforces this — empty categories are auto-hidden from the legend). And every symbol on the map must appear in the legend. Orphan symbols are the most common cartographic mistake.

Concise labels

Legend labels should be 1–4 words. "NATO members" beats "Member states of the North Atlantic Treaty Organisation"; you can put the full term in the map title or caption if needed.

Color contrast

Legend rows should be readable at the size they\u2019re displayed. The default tool uses a 13px label with sufficient contrast against a near-white legend background. If you choose an unusually pale category color, the icon stroke (a thin dark border) keeps it visible.

Marker shape conventions in cartography

Cartography has soft conventions for what each marker shape means. Following them makes your map intuitive without needing a wordy legend; breaking them is fine but the legend should clarify.

• Circle — the default "generic point of interest". Use for cities, towns, observation points, customer locations. Size variations (with the same shape) often encode population or magnitude.
• Star — capitals, headquarters, trail ends, "the most important point". Always limited to a few markers; using more than 6–8 stars on one map dilutes the meaning.
• Triangle — peaks, mountains, military features (the convention dates back to 19th-century military topographic maps where triangles meant fortifications).
• Diamond — airports, transport hubs, rest stops, anchorage. The four-point symmetry suggests "junction" or "hub".
• Square — grid references, facilities, schools, fixed installations. Squares read as "buildings" in most cartographic traditions.

Map with Legend Maker lets you mix shapes within one map. A typical hiking map might use triangles for peaks, stars for trail ends, circles for waypoints, diamonds for shelters, and squares for ranger stations — five categories, five shapes, a single dense legend that is instantly readable.

Legend positioning rules

Where to put the legend depends on what is on the map and where the focus area sits. Map with Legend offers four corners — top-right (default), top-left, bottom-right, bottom-left — plus a "hidden" option for cases where the legend is rendered separately (handout sheet, slide caption).

General rules: place the legend in the corner with the least map content. For a US map focused on the Midwest, the bottom-right (over the empty ocean east of Florida) often works. For a Europe map centered on Germany, the bottom-left (over the empty Atlantic) is traditional. For a world map, the top-right is the dataviz convention; the bottom-left is the political-cartography convention. Map with Legend gives you all four — pick by visual balance, not by rule.

Map with Legend Maker vs other tools

Honest comparison against the alternatives. Each tool wins different scenarios — the table is a feature checklist, not a value judgement. We won\u2019t do everything Photoshop or QGIS does, but we are the fastest path from blank map to finished annotated map.

MapChart is the closest sibling tool — same flat cartographic style, similar use cases — but the legend management is manual, and the mobile experience is desktop-resized. Datawrapper wins for chart-style data viz with embed-ready output but the legend follows the chart, not the user. Photoshop and Inkscape give full control at the cost of bringing your own basemap and assembling the legend by hand. Google My Maps wins for tooltip-rich Google-Maps-style overlays but has no real legend. QGIS is the professional tier — capable of anything but with a learning curve measured in weeks.

Available base maps

Eight base maps cover global, country, and continent scales. All boundaries come from public-domain Natural Earth (1:50m scale) and US Census Bureau TIGER/Line files. Switch freely; your categories carry over but markers and region fills reset (because the coordinate system is base-map-specific).
