Dominoes is a fun game that people play all over the world. The pieces of the game called “tiles,” come in different sizes. The size of a domino tile is usually based on how many dots it has on each end. The most common sizes are double-six to double-nine. The size of the tiles can change how long the game is and how hard it is.  In this article, we will explain the standard sizes of domino tiles and what makes them different.

The standard size of a domino tile is 1-7/8 x 15/16 x ¼ inches or 4.8 x 2.4 x 0.6 cm. But don’t let that limit you! Dominoes come in many different sizes, from mini to jumbo and even special tournament tiles.
