What is a category in chess?
- Competition
- Format
- Scores
Category is a tournament term: the category of a tournament is a measure of its strength based on the average FIDE rating of the participants. The category is calculated by rounding up the number: (average rating − 2250) ÷ 25. So each category covers a 25-point rating range, starting with Category 1 which spans ratings between 2251 and 2275. This affects how games are organized, scored, paired, or decided.
