Interactive maps for tabletop campaigns
Two different things get called campaign maps. A battle map is a tactical grid for one encounter and belongs in your virtual tabletop. A campaign map covers a region, carries markers that link to real lore entries, and belongs in your wiki. Most groups need both, and they come from different tools.
What a linked campaign map actually does
It converts geography into player decisions. A party looking at a map with three roads makes a choice. A party told there are three roads waits to be pointed at one. This is the single biggest difference a shared map makes to a session, and it has nothing to do with the map looking good.
It prevents travel-time drift. Journeys get timed by pacing: three days because the scene needed three days. A map with a scale and a fixed travel rate makes every journey a derived number instead of an invented one, which heads off a lot of player complaints.
It is a better index than a folder. At the table you rarely remember an NPC’s name. You remember where the party met them. A map whose markers link to entries makes that a usable route to the information.
Battle maps: the VTT’s job
Foundry VTT. $50 one-time for the host, players free. Dynamic lighting and fog of war are the reason most groups move here, and the module ecosystem covers nearly everything. Self-hosting costs nothing; managed hosts run roughly $3.50 to $5 a month. (Verified 22 September 2026.)
Roll20. Free tier is usable; dynamic lighting arrives on Plus at $5.99/month, API scripting on Pro at $9.99/month. Nothing to install, which is the appeal. (Verified 22 September 2026.)
Owlbear Rodeo. Worth knowing about if you want a shared map surface with almost no setup and none of the automation.
Campaign maps: the wiki’s job
vvd. Markers and zones that link to real entries, with the map sitting beside the lore rather than in a separate tool. Free tier covers one world; paid plans from $5.75/month. (Verified 22 September 2026.)
World Anvil. Interactive map layers with the most mature player-visibility controls in the category, built over years.
Kanka. Map entities with markers and layers, on a free tier.
Drawing the map
None of the wikis are drawing tools, and you should not expect them to be.
Inkarnate. Browser-based, with a large asset library, and it produces maps that look properly made. Free tier available; $5/month or $25/year. (Verified 22 September 2026.)
Wonderdraft. Desktop, one-time purchase, strong on regional and world maps. Works offline and you own it outright.
The standard setup, and the one worth copying: draw in Inkarnate or Wonderdraft, export the image, upload it as the base layer in your wiki, then place linked markers on top. You get the drawing quality of one tool and the linking of the other.
What to put on it
Less than you want to.
Only places that have been used or are about to be. A map dense with names nobody has visited is decoration, and it makes the used places harder to find.
Regions, not just pins. A zone covering “territory the Compact still holds” carries more weight than twenty city markers, because its edges are where the conflict is.
The scale, visibly, with a travel rate. One line. The most useful thing on the entire map.
Reveal progressively. Per-marker visibility lets you hand players a map that grows as they explore. A fully revealed world map on session one removes most of the reason to explore it.
When you do not need one
If the campaign happens in one city and travel is never a constraint, a map is a pleasant way to avoid prepping the session. The honest test is whether you can name a decision the map would change. If not, you want a picture, and Inkarnate will sell you a lovely one for five dollars.
Frequently asked
What is the difference between a campaign map and a battle map?
Scale and purpose. A battle map is a tactical grid for one encounter, and lives in your VTT. A campaign map covers the region or world, carries linked markers to places and NPCs, and lives in your wiki. Most groups need both, from different tools.
What is the best app for interactive campaign maps?
For markers that link to real lore entries, vvd, World Anvil and Kanka all do it well. For drawing the map itself, Inkarnate at $5/month or $25/year and Wonderdraft as a one-time purchase produce better-looking results than any wiki's built-in drawing tools.
Do my players need to see the map?
A shared map is one of the highest-value things you can give a party, because it converts your geography into their decisions. Use per-marker visibility so you can reveal places as they are discovered rather than showing everything at once.
Can I use an Inkarnate map in Foundry or Roll20?
Yes. Export as an image and import it as a scene. For a campaign map rather than a battle map you will usually get more out of putting it in your wiki, where markers can link to entries.
