Building Your First Dungeon Tiles: Scale, Grid Size, and Layouts
A useful first set of dungeon tiles should produce several playable room shapes, fit your miniatures and store without fragile projections. Begin with an agreed grid and a paper layout before cutting or painting a large number of pieces. Tiles are a playing tool first and decorative scenery second: players need to see entrances, count movement and reach figures without dismantling a room. This makes a small, versatile starter set more useful than a single enormous custom dungeon.
Decide what a square represents
Consult the rules for the game you actually play. Dungeons & Dragons’ published grid variant, for example, describes each grid square as representing five feet of fictional space. That is an in-game measurement, not necessarily a physical one-inch requirement for every tabletop system. Choose the physical tile size by comparing the bases of your miniatures and the measurement convention of your game. Some games use hexes, rulers or theater-of-the-mind positioning instead.
If you choose a one-inch physical square for a homemade grid, test the bases and figures you intend to use. Oversized creatures can occupy multiple squares and doors may need room for projecting weapons and wings. Avoid assuming all figures marketed as the same scale have identical base footprints.
Sketch a flexible starter layout
Draw a few room modules: a small square chamber, a rectangular hall, a corridor, a junction and a doorway. Keep dimensions compatible so tiles can connect without creating awkward half-square gaps. Decide where walls are represented by lines and where physical walls stand upright. Physical walls add atmosphere but can obstruct sight lines and make it difficult to move miniatures.
Wizards of the Coast’s Campaign Case terrain uses reusable double-sided interlocking tiles and feature clings, while its Dungeon Master’s Screen: Dungeon Kit uses modular geomorph cards for planning. Both demonstrate the benefit of rearrangeable spaces instead of a single fixed map.
Build with alignment and durability in mind
- Make one accurate master grid or template.
- Cut a small test room and corridor using material-appropriate tools.
- Dry-fit adjoining edges and check door locations.
- Set a few actual miniatures on the tiles to test handling clearance.
- Mark entry, stairs and blocked passage symbols consistently.
- Choose a storage box and label modules before duplicating them.
- Add texture and color only after the geometry works.
This avoids investing hours in stonework only to discover the corridor width is unsuitable. If using foam, verify coating compatibility and follow cutting-tool safety guidance. If using card or MDF, consider edge protection and water-based paint exposure to avoid warping.
Make doorways readable
A doorway should be obvious even when a figure stands beside it. Use a gap, contrasting threshold or removable door component. Doors that swing or clip in can be fun, but their hardware should not crowd the squares or fall off during setup. For a first set, a flat doorway marker may be more durable than an intricate hinge.
Distinguish open passages, locked doors and walls with simple consistent symbols. The artwork can carry a strong fantasy theme while leaving movement information legible. If players constantly ask whether a seam is an opening, refine the visual language.
Test three sample encounters
For a hypothetical test, arrange a straight corridor leading into a small room, then rotate pieces into a branching junction, then build a loop with two entrances. Put figures in the rooms and trace a typical movement path according to your chosen game’s rules. Do players have to remove walls to reach minis? Does the table have enough space for the full arrangement? Can all pieces pack into the box?
The answer may lead to wider corridors, lower wall sections or fewer oversized decorative props. Record the changes before making additional modules.
Paint for clarity before ornament
A restrained gray or brown stone palette helps figures stand out. Darken grout lines, lighten exposed edges and add a few deliberate cracks. Avoid huge scatter pieces that obscure the grid. Use a finish compatible with the tile substrate and let it cure before stacking. Keep the base grid consistent for every future extension so the system remains expandable, rather than becoming a set of incompatible one-off scenes.
