How to Choose a 2D or 3D Virtual Tabletop for Custom Maps and Play
If you are choosing a virtual tabletop (VTT) to build maps and run a roleplaying game, start with the kind of map you want to make and how much setup you want during play. A 2D VTT typically places tokens and drawings over a flat map image or canvas; a 3D VTT lets you construct or arrange a space with depth and a movable camera. Pick 2D when your maps are mostly images, sketches, or tactical layouts and you want a direct route from preparation to play. Pick 3D when height, room shape, and a view around the scene are central to the encounter—and you are willing to spend time building and navigating that space.
What does “2D versus 3D” mean for map building?
The distinction is chiefly about the map-making and viewing workflow, not the genre of game or the rules being played. In a 2D workflow, you usually import a background image, align a grid, and add tokens, drawings, notes, or fog. Owlbear Rodeo, for example, describes a scene as an infinite canvas that can hold maps, tokens, and drawings; its maps can be reused across scenes. Foundry VTT likewise supports scene backgrounds, adjustable grids, and image tiles placed over a scene. (Owlbear Rodeo: Scenes; Foundry VTT: Scenes; Foundry VTT: Tiles)
In a 3D workflow, the map is built or assembled as a space that players view through a camera. TaleSpire describes itself as a graphical tabletop where a game master builds a campaign in-game, and its documentation covers finding and placing community-made builds. This approach makes elevation and spatial presentation part of the map itself. It also makes camera framing and the time needed to assemble a scene part of your preparation. These are practical differences to assess in a trial, not guarantees about every tool labeled “2D” or “3D.” (TaleSpire; TaleSpire: Using the Slab Browser)
Which map tasks suit a 2D VTT?
Choose a 2D-first workflow if you already make or collect flat battle maps, want to sketch rooms as the party explores, or need a clear top-down view for positioning. It can also suit groups that change locations often: Owlbear Rodeo’s documentation describes creating separate scenes and reusing a map image across them. Foundry’s scenes support square, hexagonal, and gridless options, and its tiles let a game master layer images over the background. That can support modular layouts without constructing a full 3D environment. (Owlbear Rodeo: Scenes; Foundry VTT: Scenes; Foundry VTT: Tiles)
A flat image can show convincing perspective art, but the image itself does not establish playable height or line-of-sight rules. If the encounter depends on a balcony, a hidden passage, or who can see over a wall, decide how you will represent and adjudicate it. You might use separate map layers or simple notes; the exact tools vary by VTT. Test a representative scene before committing to a workflow that depends on complex vertical movement.
When is a 3D VTT worth the extra setup?
Try a 3D VTT when players need to inspect a location from different angles, when stacked floors or vertical terrain shape decisions, or when building the environment is itself part of the appeal of preparing a session. A 3D view can make physical relationships between rooms and objects easier to convey, but it does not remove the need to make those relationships playable. Check whether the game master can select a useful view, move tokens easily, and keep important features visible during a typical turn.
Treat the build as a prop for play, not a measure of how much preparation a session needs. Start with the areas players can reach, add distinctive landmarks, and leave decorative detail until you know it helps the group read the space. If the VTT offers reusable community builds, test one before deciding whether you need to construct every location yourself; TaleSpire’s official guide explains how its in-game Slab Browser brings community builds into the game.

How do grid alignment, walls, and lighting affect the choice?
For either workflow, verify that the map supports the movement and visibility rules you use. In a 2D image-based setup, align the grid before adding map details. Foundry’s documentation warns that changing grid size later can move the alignment of walls, lights, notes, and tiles. Its content guide also explains that background dimensions and grid spacing need to match if you plan to place accurate walls. This makes a map with a known grid scale easier to configure than an image whose scale you must estimate. (Foundry VTT: Scenes; Foundry VTT: Content Creation Style Guide)
If you want tokens’ sight and light to respond to walls, include the setup work in your comparison. Foundry uses wall segments to restrict vision or movement, with different wall types for boundaries such as doors and windows; its lighting tools interact with walls and fog of war. Those tools can support a detailed encounter, but every relevant boundary and light source needs to be placed and checked. For a simpler scene, manual fog or a map that already depicts darkness may be quicker. (Foundry VTT: Walls; Foundry VTT: Lighting)
A short trial can expose the real tradeoff
Before choosing, build one scene that resembles an ordinary session rather than a showcase map. Use a room with a doorway, a corner, a token with a light source, and one feature at a different elevation if that matters to your game. Then test the same encounter in each candidate VTT, or test one candidate against your current workflow.
Check these tasks in order: import or create the map; set and verify its grid; place and move tokens; reveal or hide an area; show a feature that matters to the encounter; and switch scenes. In a 3D VTT, also test camera movement and whether players can understand the scene from the view they actually use. In a 2D VTT, test grid alignment and whether important details remain legible beneath tokens and overlays. Note where you pause to find a tool or correct a mistake: those friction points are more useful evidence than a feature list.
Use these decision rules
Choose 2D if you want to adapt image maps quickly, draw locations on a shared canvas, or keep a strong top-down view. Choose 3D if you expect players to use height and different viewing angles often enough to justify building and managing a spatial scene. If you are unsure, begin with the simpler 2D test: it can show whether flat maps already support your encounters. Move to 3D when a specific recurring task—such as communicating stacked rooms—remains awkward, rather than assuming a more elaborate map will improve every session.
Whichever you pick, keep a fallback for the session: a simple overview image, a brief verbal description, or a quick sketch can carry play through a camera or map problem. The useful choice is the VTT whose map workflow makes your usual locations clear and manageable for both the game master and the players.
