What is the max length a Sprint can be?

The maximum length a Sprint can be is not exceeding one calendar month. This guideline is outlined in the Scrum framework, which emphasizes that Sprints should have a consistent length to promote a regular cadence and enable predictable delivery of increments. Sprints are designed to allow teams to inspect and adapt their work regularly, and having a standardized duration helps in maintaining this rhythm.

A timeframe of one month or less ensures that teams can iterate quickly, gain feedback, and make necessary adjustments in their subsequent work. This timeframe also minimizes risk and helps in better planning, as stakeholders can better anticipate when new features or product increments will be delivered.

While a Sprint can be shorter than one month depending on the team's needs, it must never extend beyond one calendar month. This constraint helps prevent long periods of uncertainty and misalignment with Agile principles, which prioritize regular delivery of value and adaptability.
