How it works
Add response and logic load
Open responses, grids, branches, validation, and instructions require more time than a short single-choice item.
Review the estimate
Use the estimated range as a planning input, then time a pilot with representative respondents on their likely device.
Frequently asked questions
What does Survey Length Predictor calculate?
It estimates completion time from the number and type of questions, branching or validation steps, and reading load entered.

How should participant data be handled?
Use aggregated counts where possible, collect only necessary information, obtain informed consent, and follow applicable privacy and research policies.
When should I recalculate Survey Length Predictor?
Recalculate when the audience, sample, source evidence, method, constraints, or decision changes materially.
