What Size Dice Set Should You Buy for RPGs

Not all RPG dice sets are the same size. Learn which polyhedral set fits your game—from standard 7-dice to expanded 11-dice sets like the ECLIPSE Royal Purple.
Quick answer
For most RPGs, a standard 7-dice polyhedral set works fine, but modern games like D&D 5e often need extra D6s and D20s, making an 11-dice set a smarter buy.
Why set size matters for different RPG systems
A classic 7-dice set includes one each of D4, D6, D8, D10, D12, D20, and a percentile D10. That covers basic needs for many tabletop RPGs, but modern systems—especially D&D 5e—frequently call for multiple D6s for damage rolls or extra D20s for advantage. An 11-dice set adds those extras without forcing you to buy a second set.
The trade-off is portability. A 7-dice set is lighter and fits in smaller pouches. If you play rules-light games or only run one-shot sessions, the smaller set may be enough. For regular campaigns or games with frequent multi-dice rolls, the expanded set saves time and keeps your dice tray organized.
Acrylic vs other materials: what it means for size and feel
Acrylic dice are the most common material for affordable, colorful RPG sets. They are lightweight, easy to read, and available in many styles. The ECLIPSE Royal Purple set uses acrylic, which keeps the price low while still offering a premium look with swirl effects.
The main trade-off is durability. Acrylic dice can chip or scratch if dropped on hard surfaces. If you play on a dice tray or soft mat, acrylic is fine. For heavy travel or outdoor gaming, consider resin or metal dice—but expect higher cost and weight.
How to choose your RPG dice set size
- Count the dice you roll most often: If your game uses many D6s (e.g., Shadowrun, GURPS) or frequent D20 rolls with advantage, choose an 11-dice set. For games that use each die once per turn, a 7-dice set is sufficient.
- Consider your storage and travel setup: A 7-dice set fits in a small pouch or dice bag. An 11-dice set with a storage box is bulkier but keeps dice organized and protected. If you carry multiple sets, the box can hold up to 40 dice. Check your dice bag or tray size before buying an expanded set.
- Match the set to your game system: D&D 5e benefits from extra D6s and D20s. Pathfinder 2e uses many D10s for damage. Call of Cthulhu mostly needs D100 (percentile). Pick a set that covers your system's most common rolls.
