A multi-step form splits a long form into steps. Conversion can be up to 86% higher than single-step.
Why it works
Psychology: a small task feels easier. Dopamine after each step. Sunk cost keeps users going.
When to use
7+ fields. Conditional logic. Complex processes.
Step division
Logical grouping. 3-7 fields per step. 3-5 steps ideal.
Progress indicator
Progress bar, step indicator, step list. Step list is the best of the three.
Navigation
\"Next\" primary, \"Back\" secondary.
Per-step validation
Validate only the current step.
Save progress
localStorage or server. Resume where they left off.
Final review
All entered data before submit. \"Edit\" links.
Conditional fields
Choices affect later steps.
Mobile
Large buttons, vertical, swipe gestures.
Animation
Slide 200-300ms.
Mistakes
Too many steps, no progress, no back button, no save.
Tools
WPForms, Typeform.
