A battle map is a scaled, top-down map used during tabletop RPG encounters to show where characters, monsters, and terrain sit relative to each other. You use one when positioning matters — combat, chases, traps, room-by-room exploration — and skip it for purely narrative scenes. You can make one by drawing terrain in a vector editor, placing assets, then exporting for screen, print, or a virtual tabletop. DungeonFog is one tool built for exactly this workflow.

Battle map vs. world map: what's the difference

These two map types answer different questions, and mixing them up is the most common early mistake.

A battle map zooms in far enough that a single chair or pillar changes your tactics. A world map zooms out far enough that a single chair is invisible. You generally need both over a campaign, but they serve different moments at the table.

When to actually put a battle map down

Reach for a battle map when the answer to "where exactly is everyone?" changes the outcome:

• Combat — line of sight, flanking, area-of-effect spells, and movement speed all depend on position.
• Dungeon crawling — doors, corridors, and room shapes matter for exploration and ambushes.
• Chases and escapes — distance and obstacles drive the tension.
• Stealth and traps — who is standing where determines what gets triggered.

Skip the map for shopping, negotiation, travel montages, and any scene where nobody cares about exact distance. Forcing a grid onto a conversation slows the game down.

How to make a custom battle map

DungeonFog describes a three-step process: create a map, place assets, then export and play. Here's what each step involves and what to expect.

1. Draw the terrain

Start with the layout — dungeon walls, building floor plans, or overland terrain. DungeonFog uses a vector-based editor, which means shapes stay sharp when you scale or print them, rather than turning blurry like a stretched bitmap. Draw the rooms and corridors first; decoration comes later.

2. Place assets

Populate the map with props, furniture, and terrain features. DungeonFog's library lists over 3,000 assets spanning different time periods and settings, and new asset packs are released monthly as part of its premium content subscription. Search the library for the pieces that match your story rather than settling for whatever's closest.

3. Export and play

You can play with others inside DungeonFog itself, or export and print the map. Exporting is where your earlier choices pay off — a vector map holds up at print resolution, and a well-scaled grid keeps tokens aligned.

Key considerations before you commit

• Grid scale. Decide your squares-per-inch (or per-5-feet) before you draw, not after. Changing it later means redoing the layout.
• Resolution. If you plan to print, you need higher resolution than for on-screen play. Vector output helps here.
• Asset library size. A bigger library means less time hunting for the right prop — but also more browsing. Check whether the library covers your campaign's setting (fantasy, modern, horror, etc.).
• Where you'll play. On screen, printed, or inside a virtual tabletop each has different export needs.

Ways to play with your map

• On screen — display the map on a TV or monitor laid flat or mounted, and move physical minis on top.
• Printed — export at print resolution and tile the pages for a physical battle mat.
• In a virtual tabletop — play with others inside DungeonFog, or export the file for use in your VTT of choice.

The practical takeaway

If you only need a quick sketch, paper and a marker still work. If you want reusable, high-detail maps that survive printing and scaling, a vector editor with a large asset library saves real time across a campaign. DungeonFog fits that second case — free to sign up, with premium memberships and a marketplace for additional content. Check the pricing page for current tiers before committing, since asset packs and premium features sit behind that subscription.
