How long should your course be?
Pick a length that matches the outcome: fewer lessons for one job-to-be-done, more depth for ongoing practice.

Practical length benchmarks
A focused skill course (learn one thing, apply it immediately) typically runs 60–120 minutes of video across six to twelve lessons. A comprehensive course covering a full topic from beginner to advanced can run three to six hours, but should be structured so students can stop at the end of each module with something usable.
