Kiwisizing.com — E-commerce

Kiwisizing.com integrates with Shopify and other e-commerce platforms to recommend the correct clothing or shoe size based on customer measurements. It uses AI and machine learning to analyze fit data and reduce return rates caused by sizing mismatches, a common problem for online retailers.

What it does

Shoppers enter their height, weight, and body shape, or select a brand they already know fits. Kiwisizing's algorithm maps that data to the store's size chart and suggests the best size. The tool offers a customizable widget, supports multiple input methods (body, brand, or product-specific), and provides return-rate analytics via an easy-to-use dashboard.

Who it is for

Kiwisizing.com is best for online clothing and shoe retailers with high return rates, e-commerce brands selling items with inconsistent sizing across manufacturers, and stores looking to improve customer confidence and conversion rates. It is less suited for digital product sellers or businesses without size variability.

Real use cases

A Shopify store selling footwear can use Kiwisizing.com to let customers compare their known size in a familiar brand (e.g., Nike) to the store's sizing, reducing fit-related returns. An apparel brand with inconsistent sizing across factories can deploy the AI recommender to suggest the correct size based on body measurements, improving the shopping experience and lowering return rates.
