A battle mat is a gridded playing surface DMs use to map out encounter areas during combat. Miniatures or tokens sit on the grid, each square representing 5 feet of in-game space. It's one of the more practical accessories for combat-heavy campaigns and one of the more confusing to buy because the product descriptions often don't clearly communicate what matters.
For most groups a reusable dry-erase or wet-erase vinyl or rubber mat in approximately 23 by 27 inches with a 1-inch grid is the practical choice. It covers a typical encounter space and can be drawn on and wiped clean between sessions. Printed multi-map packs are cheaper per encounter but single-use. Premium rubber mats are heavier and lay flat better than vinyl. Size and grid scale (1-inch squares) are the two specifications that matter most.
Why Grid Scale Matters
Standard D&D combat uses a grid where each square represents 5 feet. Standard miniatures are made at 28mm scale, designed to fit one per 1-inch square. The 1-inch (25mm) grid is the near-universal standard across D&D battle mats, miniatures, and accessories.
When buying a battle mat, confirm it uses a 1-inch grid. Some mats designed for other games use different scales. Most D&D-marketed products will specify this, but it's worth verifying in the product description if you're buying a mat not specifically branded for D&D.
Reusable Dry-Erase and Wet-Erase Mats
These are the workhorse option for most ongoing campaigns. The DM draws the encounter map with a marker at the start of a combat, runs the encounter on the drawn map, then wipes it clean for the next session.
Dry-erase vinyl mats: The most common format. Whiteboard-style surface that dry-erase markers clean off completely. Available in single-sided and double-sided formats (one side square grid, one side hex grid for groups that use hexes). Tend to curl at the edges unless weighted or rolled flat.
Wet-erase vinyl mats: Similar format but requires a damp cloth or water to clean. Wet-erase markers don't smear as easily during play as dry-erase, making them more durable for long combat encounters. Slower to clean between sessions.
Rubber mats: Heavier than vinyl, lie flat on the table without curling, and are more durable. The EVERGAME and similar rubber mats in the C3 D&D shop are in this category. Preferred by groups who run regular sessions and want a mat that holds up over time. Higher price point than vinyl.
Printed Map Packs
An alternative to blank reusable mats. Pre-printed maps cover specific encounter types: dungeon corridors, tavern interiors, forest clearings, city streets. The DM selects the appropriate map for an encounter rather than drawing it.
Single-use paper maps: Inexpensive per set, but single-use. Suitable for groups that don't run the same encounter twice and want visual variety without drawing skills.
Reusable printed sets: Some map products are printed on heavier stock or laminated. The oTTRPGo nine-pack and similar products in the C3 D&D shop offer multiple printed maps in a single purchase.
The practical trade-off: printed maps give better visual quality than hand-drawn, but a blank reusable mat is more flexible because you can draw any layout you need. Most regular campaign DMs end up with both.
Premium Battle Maps
Several products in the premium range combine artistic map quality with durability. Da Vinci's Room produces rubber game mats with detailed printed artwork in two-sided configurations (one for a specific dungeon layout, one for a different setting). These look significantly better than drawn mats but sacrifice flexibility — you're using the map the manufacturer designed, not drawing your own.
WizKids Icons of the Realms Battle Mats are setting-specific premium mats with official D&D artwork. The Desert mat in the C3 D&D shop is an example. Useful for campaigns where specific terrain types feature prominently.
Sizing Considerations
Battle mats are typically measured in inches. Common sizes available in Australia:
- 23 x 27 inches: Covers a standard medium encounter comfortably. Fits most kitchen tables.
- 27 x 27 inches: Slightly larger, useful for large-scale encounters with many combatants.
- 3-foot rubber mats: Good for groups that regularly run large encounters.
- 4-foot rubber mats: Large encounter coverage, not suitable for all tables.
A 23 x 27-inch mat covers most encounters. Larger mats are useful but limit which tables you can play on. Consider your usual play space before buying a very large mat.
All battle mats mentioned here are available through the C3 D&D shop.

Frequently Asked Questions
What size battle mat do I need for D&D? A 23 by 27-inch mat covers most standard encounters. Larger sizes give more room for big encounters but may not fit smaller tables. Start with a medium size and scale up if needed.
What is the difference between dry-erase and wet-erase mats? Dry-erase cleans with a cloth, faster between sessions. Wet-erase requires a damp cloth but smears less during play. Both work for D&D. Wet-erase is slightly preferred for long combat encounters.
Do I need a battle mat to play D&D? No. Theatre of the mind (verbal description without visual aids) works fine and many groups prefer it. A battle mat is most useful for groups that find verbal-only combat confusing, particularly in encounters with many combatants.
Are printed map packs worth buying over a blank reusable mat? Printed maps look better than hand-drawn. A blank reusable mat is more flexible because you can draw any layout. Most regular DMs end up with both — a reusable mat for drawing custom layouts and printed maps for common encounter types.
Will standard D&D miniatures fit on these mats? Yes, provided the mat uses a 1-inch grid. Standard D&D miniatures are sized to fit one per 1-inch square. Verify the grid specification before purchasing any mat.
