Here are detailed insights and numbers related to how quiz length affects user engagement rates, based on studies and general patterns:

Short quizzes (5–10 questions):
- 80–90% completion rates.
- Engagement remains high due to low cognitive load and time commitment.
- Ideal for casual quizzes, such as Buzzfeed-style personality quizzes or quick trivia.
Medium quizzes (11–20 questions):
- 60–80% completion rates.
- Slight drop-off compared to short quizzes, but still manageable for users who are moderately interested.
- Often used for e-learning assessments or in-depth personality tests.
Long quizzes (20+ questions):
- 30–50% completion rates.
- Engagement decreases significantly as users perceive them as time-intensive.
- Users who stay tend to be highly motivated, such as professionals or students in certification courses.

Mobile users typically have 15–20% lower tolerance for long quizzes compared to desktop users due to shorter attention spans and screen size limitations.
Example:
- A 15-question quiz might see 70% completion on desktop but only 55% on mobile.
- Drop-off rates are higher for quizzes exceeding 10 questions on mobile.

The first 2–3 questions are critical to hook users. If users feel disengaged or overwhelmed, 10–20% drop off immediately.
Completion rates tend to decline 5–15% for every 5 additional questions beyond the optimal length (10–15 questions).

5 minutes or less: Quizzes that take under 5 minutes to complete generally retain 80–90% of users.
5–10 minutes: Retention falls to 60–80%.
Over 10 minutes: Retention drops below 50%.

Multiple-choice, visual, or interactive questions:
- Retain users better, even in longer quizzes.
- Studies show that adding visuals boosts engagement by 15–20%, particularly on social media platforms.
Text-heavy or complex questions:
- Result in a drop-off rate of 10–15% higher than visually engaging questions.

Buzzfeed and similar platforms report:
- Quizzes with 6–12 questions receive the highest shares and engagement.
- Longer quizzes (>15 questions) are shared 30% less on average due to reduced completion rates.

Progress indicators:
- Quizzes with clear progress bars reduce drop-off rates by 15–20%.
Intermittent rewards or feedback:
- Adding instant feedback after every 5 questions improves engagement by 10–25%.
Adaptive design:
- Mobile-friendly quizzes see 20% higher completion rates than non-optimized ones.

Stick to 10–15 questions for maximum retention (completion rates of 70–80%).
For lead generation or casual fun, limit to 7–10 questions (completion rates of 80–90%).
In educational settings, keep quizzes under 20 questions unless motivation is high.
