Calculate the variant volume, total traffic, duration, and guardrails before launching a paid social creative test.
Plan a readable creative test in three steps
- 01
Enter the test assumptions
Add baseline conversion rate, detectable lift, confidence, power, daily traffic, and the number of variants.
- 02
Calculate required volume
Get sample size per variant, total traffic, expected duration, and the comparisons created by your variant count.
- 03
Launch with guardrails
Use the guardrails to keep creative variables clean, avoid early calls, and plan the next video ad batch.

AB Test Sample Size Calculator questions
What is an AB test sample size calculator?
An AB test sample size calculator estimates how much traffic each variant needs to detect a planned lift with a selected confidence level and statistical power.
How much traffic do I need for a creative test?
Traffic depends on your baseline conversion rate, minimum detectable lift, confidence level, power, and number of variants. Smaller lifts and more variants require more traffic.
Should I test many ad creatives at once?
Testing too many variants can spread traffic too thin. Use enough variants to answer the creative question, then turn the winner into the next batch of structured video ad variations.
How does Sovran help after the test?
Sovran helps teams convert winning hooks, bodies, proof moments, and CTAs into fresh modular video ads so learnings become the next production sprint.
Turn winning tests into fresh video ads
Use Sovran to turn validated hooks, proof points, and CTAs into modular video ad variations for the next test cycle.
