Smart Sizing accurately captures user size information both through search and collections filtering and variant selection. By prompting users to filter by their known size, indicating low stock in their size on collections and search, and preselecting size variants, and only recommending available products in the users size, merchants can increase conversion significantly.

While this solution is a known conversion driver in the apparel and footwear space, the potential applications are widespread wherever definitive variant-level attributes are an absolute must for the consumer.
