How many letter tiles are in a standard English-language Scrabble set?

How to get close to this number

Round numbers win in game design. A tile set has to be large enough for a full game with several players and small enough to handle, and a hundred is the obvious choice inside that range. When a game component count could be anything, expect the round number.

The distribution in the explanation is the genuinely clever part: letter frequencies mirror how often each letter appears in English text, which is why there are a dozen E tiles and a single Q. The designer counted letters in newspaper pages to set the distribution, which is an empirical approach to game balance that predates the field of game design.

That also makes the set language-specific in a way people forget. A Spanish, French or German set has different letter counts and different point values, because the underlying frequency distribution differs. The tile total stays around a hundred, but what is on the tiles changes with the language — the design is a frequency table wearing a board game.
