Custom D20 and Oversized Dice: Hero Pieces and Collector Items

While most custom orders are standard 7-piece sets, the oversized d20 has become a product in its own right — a statement piece brands use as a collector item, a Kickstarter reward tier, a shop centrepiece, or a giveaway. Its size makes the material and engraving the star, which is why it works so well in metal and gemstone.

What size is an oversized d20?

Standalone oversized d20s usually run from about 25mm up to 55mm or larger, well beyond the 16–20mm of a die in a normal set. The larger the die, the more dramatic the material looks and the more presence it has on a shelf or table, which is the whole point of a hero piece.

Best materials for a giant d20

• Metal — weight and crisp engraving make a large metal d20 feel like a trophy; plating and enamel add finish options.
• Gemstone — a big d20 carved from amethyst, obsidian, or clear quartz is a striking natural collector piece.
• Resin — allows galaxy swirls and inclusions at a lower cost, good for colourful oversized giveaways.

What are oversized d20s used for?

• Collector and limited-edition pieces sold at a premium.
• Kickstarter and crowdfunding reward tiers that stand out.
• Retail and event centrepieces or window displays.
• Corporate gifts and giveaways with an engraved logo.
• Accessibility, where larger numbers are easier to read.

Cost and ordering

Because an oversized d20 uses far more material than a standard die, it costs more per piece, especially in metal and gemstone where the raw material drives the price. It can be engraved with your logo, numbers, or a custom design just like any of our dice. Tell us the size, material, and finish you want and we will send a quote within 24 hours.
