How many questions a survey should have, by type
A guide to how many questions to ask by survey type: 1 to 3 for transactional surveys such as CSAT and CES, 3 to 6 for relationship and pulse surveys like NPS, 6 to 12 for feature feedback and concept tests, and no more than 15 to 20 for deep research. It helps researchers, product and CX teams set a question budget before drafting. Koji can replace the longest surveys with adaptive AI interviews.
