Course Content Mix Calculator

Turn your total lesson count into a recommended split of video, reading, exercises, and quizzes, so you’re not guessing how much of the course should be watched versus practiced.

What’s the course mainly teaching

Each course type leans on a different mix of formats. Pick the closest match to how your course applies.

How this calculator works

Format count = Total lessons × Format percentage

Most course creators build the video first, then figure out reading and practice material as an afterthought, if they add it at all. That order produces courses that are heavy on watching and light on doing, which hurts completion rates more than almost anything else. This calculator flips the order by starting from a target mix, so reading and practice get planned in from the start instead of tacked on at the end.

Why skill-based courses need more exercises than video

Watching someone perform a skill doesn’t build that skill in the viewer, it builds recognition of what the skill looks like. Actually doing the exercise is what builds the skill itself. That’s why a practical, hands-on course should lean harder on worksheets and exercises than a conceptual course does, even though video usually still carries the largest single share.

Example

A 20-lesson skill-based course splits into 8 video lessons, 3 reading lessons, 7 exercises, and 2 quizzes.

These are lessons, not minutes. A single “lesson” in this split might run five minutes or forty, so use this to plan the shape of your course outline first, then estimate runtime separately with the Course Production Time Estimator once you know how many video lessons you’re producing.

What shifts the ideal mix for your course

  • How hands-on the outcome is: a course that ends in a finished deliverable needs more exercises than one that ends in understanding a concept
  • Your audience’s learning style: a more experienced audience often wants less explanatory video and more direct practice
  • Completion requirements: a certification or compliance course typically needs formal quizzes to document that learning actually happened
  • Course length: a shorter course can lean more heavily on video alone, while a longer course benefits from more variety to sustain engagement
  • Live versus self-paced format: a live cohort can shift more practice into group sessions, needing fewer standalone exercise lessons than a self-paced version of the same course

Course content mix calculator: frequently asked questions

What percentage of a course should be video?
Most courses land somewhere between 35% and 50% video, with the rest split across reading, exercises, and quizzes depending on how hands-on the subject is. A course teaching a physical or software skill usually needs less video and more guided practice than a purely conceptual course.
Do I need quizzes if my course isn’t a certification?
Not necessarily as formal graded quizzes, but some form of self-check, even a short reflection question at the end of a module, helps a student notice what they actually retained. Certification and compliance courses need them for documentation, but any course benefits from some form of checkpoint.
Should every module have the same content mix?
No, the ratios in this calculator work best as a course-wide average. Early modules often lean more video-heavy to build foundational understanding, while later modules can lean more toward exercises as students apply what they’ve learned.
What if my course doesn’t fit neatly into one of the three types?
Many courses blend two types, teaching a concept and then a related skill. Pick whichever type describes most of the course, or split the calculator’s suggested numbers roughly in half between two type presets if the course is genuinely balanced between them.
Does this account for community or discussion components?
No, this calculator covers structured lesson content only. A community discussion or live Q&A adds engagement on top of the core lesson mix rather than replacing any of these four formats.
Now estimate the production time

The Course Production Time Estimator turns your video lesson count into a realistic recording and editing schedule.
