What this tool is for
Playable D&D scenes: grids, cover, sight lines, and clear encounter spaces
RPG Map Editor is a browser-based D&D map maker for dungeon masters who want fast prep, saved projects, and clean exports. The Free plan includes 3 saved maps; Studio targets unlimited saved maps and public share links when billing is live.
Terrain brushes
Paint floors, water, grass, cave edges, and paths quickly when you need a map in minutes, not hours.
Stamps & assets
Place doors, props, obstacles, and encounter markers so players immediately understand the space.
What you can make
Built for actual game-night prep
Battle maps
Ambushes, boss arenas, taverns, bridges, and tactical set pieces. Start here if your D&D sessions use minis or a VTT grid.
Dungeon maps
Rooms, corridors, doors, hazards, secret passages, and encounter zones — designed for exploration and combat pacing.
Fantasy maps
Overland locations, villages, ruins, caves, camps, and travel encounters. Good for campaign prep and “where are we?” scenes.
D&D encounter workflow
Five-foot squares, readable cover, honest scale
Most fifth-edition style combat assumes a 5-foot grid: each square is five feet on a side. Pick a square footprint that matches the fight—tight tavern brawl versus boss arena—then keep export pixels aligned to your VTT’s pixels-per-square so movement and range templates stay trustworthy.
Common map sizes
20×20 to 40×30 squares cover many tables; larger fights trade file size for freedom of movement. See the D&D battle map size guide for feet and pixel math.
Fast session prep
Paint playable floors first, stamp props that change tactics second, reconcile the grid, export PNG—repeat weekly until the muscle memory sticks.
Indoor vs outdoor
Indoors: doors, furniture lanes, tight corners. Outdoors: trees, rocks, elevation cues, longer lanes. Both still start with terrain blocking.

Exports & play
VTT exports, table handouts, and practical output
The fastest workflow is: build the scene, lock in grid readability, iterate with stamps/props as needed, then export an image you can drop into your VTT or print for the table.
Export images
Export PNG for VTTs and handouts. Keep a consistent grid and map scale so measurements are predictable.
Layers & clarity
Use layers, shapes, and labels to keep maps readable. The goal is “players understand the space,” not decorative overload.
Player vs DM assets
Use separate drafts or overlays so you control what flattening/export shares with the table—or bring maps into your VTT and handle reveals inside the platform.

Comparison intent
How this compares to Inkarnate and other tools
If you’re evaluating tools, focus on your session workflow: saved editable projects, encounter readability, grid prep, and exports that fit your VTT. If you need a broader art-focused workflow, verify feature fit before switching.

FAQ
D&D map maker FAQ
Is this free?
Yes. The Free plan includes core editor tools and up to 3 saved maps. Upgrade only if you need unlimited saved maps or public share links.
Do I need to install anything?
No. RPG Map Editor runs in the browser. Create maps on desktop and export images for your game.
Can I use these maps in a VTT?
You can export images and use them as VTT maps or table handouts. Always verify your grid settings and scale inside your VTT.
What PNG size should I use for Roll20?
Roll20 cares about pixels per square after import. Common setups use 70 px per square for standard clarity or 140 px for sharper tokens; match your map export dimensions so the image grid lines up with Roll20’s grid overlay.
How fast can I prep a one-shot encounter map?
With terrain-first blocking, a focused stamp pass, and early grid checks, many skirmish rooms land in 10–30 minutes once the rhythm is familiar—then export PNG for play.
What does a 5-foot grid mean for map size?
Each square usually represents five feet. A 20×20-square map is roughly 100×100 feet of tactical space; multiply squares by five to think in feet, then multiply squares by your VTT pixels-per-square for export width and height.
How do indoor and outdoor encounters change prep?
Indoors needs door widths, furniture lanes, and tight corners for line of sight. Outdoors needs cover lines, elevation cues, and longer movement paths—block terrain first in both cases before dense props.
