The AI sizing tool for Shopify stores
UniMeasureAI is a camera-based sizing tool for Shopify. Shoppers measure themselves using their own phone, tablet or laptop, and receive a size recommendation matched to your size charts — directly on the product page, before they buy. No app download and no measuring tape required.
"Size and fit issues are a leading cause of fashion e-commerce returns. UniMeasureAI helps every shopper find the right size before they buy, replacing uncertainty with confidence, supporting conversion, and reducing avoidable returns across every brand you sell."
Why sizing hurts Shopify conversion
-
Sizing varies between brands and products
A medium is not a universal measurement. Customers often have to reinterpret sizing every time they shop with a new brand.
-
Uncertainty can stop a purchase
When shoppers are unsure which size to choose, they may delay the purchase, abandon the basket or order several sizes.
-
Returns reduce margin
A size-related return creates more than a refund. It can also involve shipping, warehouse handling, customer service, inspection, repackaging and delayed resale.
-
Returns create avoidable environmental activity
Every unnecessary return means additional transport, handling and packaging.
