How many questions are in a UX survey?

The maximum that you can go for in a screening questionnaire is 10–12 questions. Anything more than that, and participants will feel some untrust towards you as they are not being paid for the time they are putting in.

How many questions should a survey have?

Is there an ideal number of questions to ask in a survey? The short answer is yes! The length for a typical online survey is 15 to 20 questions. While that might sound like a small number of questions, an online survey with 15 to 20 questions will take respondents 3 to 5 minutes to complete.
