We redesigned the “Find Your Size” feature to simplify the process. Read the full write-up.
Redesigned “Find Your Size” Feature


IF we shorten instructions and reduce the “Find Your Size” feature to a single measurement input THEN the conversion rate will increase BECAUSE the process becomes faster and clearer, reducing drop-off from sizing uncertainty.
What We Changed
- Removed excess instructional text.
- Allowed input in inches or centimeters.
- Automatically calculated and displayed size.
- Integrated feature above size selector on PDP.
- Pre-selected size based on input.
The Results
We dig through every data source to map what's actually broken. By the end, there's no confusion.

Key Learnings
- AOV isn't a reliable metric for this store. There's natural fluctuation as visitors come with a pre-determined number of products they want to buy (i.e. how many kids they're purchasing for).
- Product sizing is one of the biggest complaints, and giving confidence around this objection helped remove uncertainty for many customers.
- Engagement time on the sizing component decreased because it's easier to use.
- Clearer instructions also lowered bounce rates.
- Recommendation: roll this change out to production.
