Size guide next to the size selector: +7.77% conversion rate
Placing the size guide link right beside the size selector on Attrangi's mobile product pages raised conversion rate by 7.77% and revenue by 17.80%.
ConvertPolo ran this test for Attrangi, and it was published as a VWO case study. It was a single-change A/B test.
- Conversion rate: +7.77%. More product page visitors completed a purchase.
- Revenue: +17.80%. Revenue grew more than conversion, which could mean bigger or more orders per buyer, though the source doesn't explain why.
The change
Size guide moved from lower on the page to sit beside the size selector

Control
On the mobile product page, the size guide sat away from the size dropdown. Shoppers had to look for it when choosing a size.
Variant
The size guide link was moved to sit directly next to the size selector, where shoppers pick their size.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Shoppers need sizing help at the moment they pick a size. Putting the guide there removes a search step.
- First-time buyers are often unsure how a brand's sizes run. A guide in plain view gives them the confidence to commit.
- Fewer size doubts can mean fewer shoppers leaving to check elsewhere and never coming back.
Caveats: Sample size, test length and confidence level were not shared. The result is vendor-published.

How to run this test on your store
- Hypothesis
- If we place the size guide link directly beside the size selector, then more shoppers will buy, because sizing help is there when they make the choice.
- Primary metric
- Product page conversion rate
- Guardrails
- Revenue per visitor
- Size-related return rate
- Size guide clicks
- Who should test it
- Apparel, footwear, rings and any store with sized products, especially with many first-time buyers. It matters less for one-size products or brands whose customers already know their size.
Questions
Where should the size guide go on a product page?
Right next to the size selector, where shoppers decide.
In this test, that placement lifted conversion by 7.77%.
Should the size guide open in a popup or a new page?
A popup or drawer keeps shoppers on the product page, which is usually safer. A new page risks losing them.
Can a better size guide reduce returns?
It can, if shoppers pick the right size first time.
Track size-related returns as well as conversion when you test it.
