T20, ODI and Test cricket explained
T20 and ODI cricket are limited-overs formats. A standard T20 innings allows up to 20 overs, and a standard ODI innings up to 50. Teams normally bat once each, with the second team chasing a target. A Test match gives each team up to two innings and is usually scheduled over five days. Time, declarations and draws are therefore part of the score’s meaning.
Shortened matches can have fewer overs than the standard format, and the target may be revised. Look at the match format, the innings number and the official status before comparing totals. On a scorecard, the overs notation stays a count of completed overs and legal balls, so 12. 4 is not a decimal figure in any of these formats.
