An innings in Test cricket has no fixed limit on overs ; it continues until 10 wickets fall, a team declares, or the match time runs out.

Core rule

  • In Test and other first-class cricket, an innings is unlimited overs for the batting side.
  • There is no maximum overs per innings in the Laws; the only constraints are wickets and available match time.

Daily overs requirement

  • The playing conditions require the fielding side to bowl a minimum of 90 overs per day in most modern Test matches.
  • This 90-overs figure often causes confusion, but it is a per-day quota , not an innings limit.

How an innings actually ends

An innings in Test cricket will end when:

  • All 10 wickets are down (team is all out).
  • The batting captain declares the innings closed at any time.
  • The match time expires (e.g., end of day five) while the innings is still in progress.

Typical total overs in a Test

  • Over five days, if every day reaches the minimum, a Test might have about 450 overs in total, shared across up to four innings.
  • Weather, slow over rates, or early finishes can reduce this, and extensions or make-up time can sometimes increase the bowled overs beyond 450.

TL;DR: If you are asking “how many overs in an innings of Test cricket?” the technical answer is: unlimited overs per innings; only the match duration and wickets/declaring limit it.
