The short answer: Standard tiles run about 1.0 to 1.1 inches long by 0.8 to 0.9 inches wide, and 0.5 to 0.6 inches thick – roughly the 25 to 28mm range. Big American-brand sets run closer to 34mm. Bigger tiles grip better but eat table space fast.
Tile size is the first thing you notice when you open a new set. Bigger is not automatically better – it depends on your hands and your table.
What sizes will you actually find?
- 25 to 28mm – the common standard. Fits most hands and most tables.
- 30mm – a step bigger, popular in clubs and tournaments.
- 34mm and up – the American oversized style. Great grip, big footprint.
- Travel sets – around 20mm. Fine solo, cramped for four.
How do you pick the right size?
- Measure your table first – each player needs room for two hands plus their wall.
- Match the tile to your hands: big hands love 30mm and up; small hands tire on giants.
- Match it to the game: family rounds are fine at 25 to 28mm; clubs lean bigger.
- Test before you buy if you can – borrow a friend’s set once.

Are bigger tiles easier to read?
Yes. More surface means bigger symbols, which is why senior-friendly and tournament sets usually run 30mm or larger.
Do all tiles in a set match?
They should – good sets hold a tolerance of about a millimeter. If walls stack crooked, the set is poorly made.
Can travel sets work for four players?
Technically, but you will bump elbows and knock walls. Travel sets shine solo; four players deserve at least 25mm tiles.
