Bold Metrics is a San Francisco-based technology company that helps apparel brands improve online fit and sizing through AI-powered body data. Its SaaS platform uses digital twin technology to create a shopper profile based on more than 50 body measurements, without requiring scans, photos, or measuring tapes. The platform recommends sizes by style and supports personalized fit experiences designed to build customer confidence, increase conversion and average order value, and reduce fit-related returns.

Bold Metrics offers several solutions for apparel businesses. Smart Size Chart helps shoppers choose a size and preferred fit, while Virtual Sizer provides size recommendations through an API. Apparel Insights turns consumer body data into insights that can inform decisions from design to distribution, including size charts and grading. Virtual Tailor supplies customer body measurements for custom clothiers and tailors. The company also provides body data tools for design, eCommerce, returns, and agentic commerce, along with integration and onboarding support.
