Choosing the right survey length
A short survey should generally contain between 1 and 5 questions. The exact number depends on the context and user expectation. For transactional or in-app feedback, one question often suffices; for satisfaction or experience feedback, 3 to 5 questions can provide useful nuance without fatiguing respondents.
Guidelines by use case:
- Micro-feedback (post-task or in-app): 1 question with an optional comment.
- Transactional follow-up (post-purchase or support): 1–3 questions covering satisfaction and any quick detail.
- Short research or NPS-style surveys: 3–5 questions, including one key metric and a follow-up open field.
Why brevity matters:
- Response rates drop sharply as question count increases.
- Short surveys are more likely to be completed on mobile and on the go.
- You get cleaner data: fewer dropouts and less satisficing.
Design tips for short surveys:
- Prioritize the most actionable questions and cut anything nice-to-have.
- Use branching to show follow-ups only to relevant respondents.
- Ensure each question maps to a decision or metric you will act on.
If deeper insight is required, combine short surveys with targeted interviews or occasional longer surveys to balance breadth and depth.
