The number of overs in the Asia Cup cricket tournament depends on the format being played:

• Historically, the Asia Cup was primarily a 50-over One Day International (ODI) tournament.
• Since 2016, the Asia Cup has also been played in the Twenty20 (T20) format, especially in years when a T20 World Cup is scheduled.
• For example, the 2022 Asia Cup was played in the T20 format, with matches consisting of 20 overs per side.
• The 2023 Asia Cup was played in the 50-over format.
• The upcoming 2025 Men's Asia Cup is scheduled to be played in the T20 format as a precursor to the 2026 T20 World Cup.
• The 2027 Asia Cup will return to the 50-over ODI format.

In summary:

• Asia Cup matches are either 20 overs per side (T20 format) or 50 overs per side (ODI format), depending on the edition and the format of the upcoming global tournament
