Why It Works

The Smart Size Chart™ leverages our AI digital twin platform in combination with your brand's garment data to provide detailed size recommendations to your shoppers.

Contextualized results show shoppers how a garment will fit their specific body measurements, so they can choose based on personal fit preferences.
Sizing isn't singular and preferences are unique. Empower your shoppers to find their best fit, based on their personal style, activities, and preferences.
Easy setup, just copy and paste a snippet of code and immediately provide your shoppers with a best-in-class sizing solution.

Multiple Products. Multiple Solutions.

Utilize the Multi-SSC Experience, which uses our AI-powered digital twin platform alongside your product data to deliver individualized size recommendations for multiple products displayed on a single PDP.

Help shoppers find their best fit for every piece, whether a jacket and pants, a base layer and shell, or a bra and leggings. The Multi-SSC feature provides personalized, contextualized fit guidance, so customers can confidently purchase complete outfits, coordinated sets, or layered systems.
Fit isn't one-size-fits-all, and neither is a single size chart. With Multi-SSC, shoppers can choose their best size for each item based on their body, preferences, and use cases.
Seamless to set up — a simple code snippet enables a best-in-class multi-product fit experience on your PDP.

Smart Size Chart for Kids. Smarter Shopping for Parents.

Simplify sizing for parents and caregivers with accurate, AI-powered recommendations based on just four easy inputs—no measuring tapes, scans, or photos required.

Built on over 1 million child-specific digital twins and your brand’s unique sizing data, SSC Kids continuously adapts to deliver the right fit across ages 2–19.
Help shoppers choose confidently for fast-growing kids—whether it’s everyday basics, school uniforms, or seasonal outerwear. SSC Kids provides precise, age-appropriate guidance right on your product page, so parents spend less time guessing and more time clicking add to cart.
Fit is never “one-size-fits-all,” especially for kids. With SSC Kids, every recommendation accounts for body changes, brand fit nuances, and intended use—resulting in happier customers and fewer returns.
Integration is effortless — a lightweight code snippet enables a best-in-class kids sizing experience that’s ready to scale.

With the Virtual Sizer, the entire process can be completed in a matter of minutes, allowing the sales rep to spend the additional time working new accounts or providing higher levels of support to our existing customers.
