About
Sizekick is an AI-driven sizing solution built specifically for fashion e-commerce businesses battling high return rates and low conversion caused by size uncertainty. Using proprietary mobile body scan technology, shoppers record a short smartphone video from which the AI extracts precise body measurements in real time. These measurements are cross-referenced with over 75 years of sizing and fit expertise from strategic partner Hohenstein to generate highly accurate, product-level size recommendations. Unlike static size charts or basic fit guides, Sizekick's engine continuously learns from user feedback and purchase data from day one of integration, making recommendations progressively more accurate over time. The platform offers full brand customization, ensuring the sizing journey feels native to the shop's design language. Integration is fast and lightweight, with a dedicated Shopify app and minimal technical overhead for other e-commerce platforms. As a German company, Sizekick is fully GDPR compliant — body measurement data is automatically anonymized and used exclusively for size recommendations. Key business impacts include return rate reductions of up to 50%, approximately 500g of CO₂ saved per prevented return, improved conversion rates, and fewer size-related customer service inquiries. Sizekick is ideal for online apparel retailers, premium fashion brands, and workwear suppliers looking to build customer trust and drive sustainable growth through smarter sizing technology.
