Comparing dice sizes

In the enchanting world of tabletop gaming, where every roll of the dice shapes epic narratives, the size of those dice becomes a crucial element of the gaming experience.

In this article, we embark on a journey of exploration to unravel the standard and typical sizes of polyhedral dice. From the iconic d20 to the ubiquitous d6 and various other dice types, we delve into the dimensions that define these gaming essentials.

Do D&D dice have to be a specific size?

No, D&D dice don't have to be a specific size. There is no regulated size that your dice must be for them to be permissible in play. You just need to make sure you have all the right types of dice to play D&D, including a d4, d6, d8, d10, d%, d12, and d20. They must be fair, meaning not weighted or biased.

What size are D&D dice?

Polyhedral dice, the essential tools for Dungeons & Dragons and other tabletop adventures, come in various shapes and sizes. However, when it comes to D&D, these dice are typically found in sets of seven. These sets include the iconic d20, along with a d4, d6, d8, d10, d%, and d12.

We measured a range of our most popular dice sets, from popular acrylic and resin sets to metal and liquid core sets. The size ranges for each die are as follows:

D4: 16mm-27mm

D6: 16mm-18mm

D8: 24mm-30mm

D10: 21mm-27mm

D12: 18mm-21mm

D20: 23mm-29mm

Dice sizes can vary significantly based on the brand and the materials used. The above ranges are based on a range of our most popular dice sets. This includes different dice materials such as resin, acrylic, and metal.

Liquid core dice sets are typically always much larger than standard, providing a visually captivating and satisfying rolling experience. Similarly, sharp-edged resin dice and metal dnd dice in tend to be on the larger side, catering to those who appreciate a more substantial feel during gameplay.

To ensure accuracy, we used digital callipers, measuring the d6 and d12 flat and all other dice from their lowest to highest points. The callipers we used have an accuracy of +/-0.2mm, but it’s important to remember that all dice are different, and measurements can vary slightly.

What size are standard d6 dice?

The standard size of a d6 is 16mm, approximately 0.6 inches. However, dice manufacturers offer variations, such as 14mm and 18mm d6 for those who prefer slightly smaller or larger options. Games like Warhammer 40k utilise 12mm d6 as this makes it easier to hold and roll multiple dice simultaneously.

What size are Monopoly dice?

Monopoly dice are six-sided, also known as d6. They are standard 16mm in size, featuring numbers 1 through 6. These dice are the familiar cubes used for moves and decisions in the classic game.

Why do people use different sized dice?

People use different sized dice for various reasons. Larger dice are often favoured because it is easier to see the outcome on a larger die. On the flip side, some opt for smaller dice for the novelty or the fun of rolling numerous tiny dice. Dice size choices in tabletop gaming often reflect personal preferences and the unique dynamics each player enjoys during their gaming experience.

How do you measure the size of dice?

To measure the size of dice accurately, a digital calliper in millimetre mode is ideal. Place the die securely within the calliper’s clasp, ensuring it's positioned squarely, and take the measurement for precise readings.

What size dice should I get?

Consider what feels comfortable in your hands and enhances your overall enjoyment of the game. Some players enjoy the heft and feel of larger dice, finding them more satisfying to roll, while others prefer the convenience and portability of smaller dice. It's a matter of preference and how you envision your tabletop experience.
