how many overs in a session

In mainstream cricket, a standard Test match session usually has about 30 overs bowled.

Basic answer

• A day of Test cricket is typically 90 overs , split into 3 sessions of roughly 30 overs each (morning, afternoon, evening).

• This assumes normal conditions, with teams expected to maintain about 15 overs per hour over a two‑hour session.

Important details

• Sessions are time‑based (about two hours) rather than strictly overs‑based, so the exact number of overs in a session can vary if the over rate is slow, there are injuries, reviews, or bad light.

• Umpires can extend the last session slightly to try to complete the scheduled 90 overs in a day, which can push a session a bit beyond 30 overs in practice.

Other formats

• In ODIs, people sometimes talk casually about “sessions”, but the formal structure is just 50 overs per innings , often discussed in phases like first 10, middle 30, last 10 rather than fixed sessions.

• In T20s, the idea of sessions is mostly informal since the innings is only 20 overs , usually broken into powerplay, middle, and death overs, not time‑based sessions.

TL;DR: If someone asks “how many overs in a session?” in cricket, they almost always mean Test cricket, where the rule‑of‑thumb answer is about 30 overs per session under normal conditions.
