How it works

  1. 1

    Upload your size chart

    Import the CSV you already have. MatrixFit validates it and stores it as a reusable size matrix.

  2. 2

    Assign it to products

    Pick the products or collections each matrix covers. The widget appears on those product pages automatically.

  3. 3

    Watch the fit data work

    Shoppers enter two measurements and get a size with a confidence score. Analytics shows which sizes convert.

It lives on your product page

No theme code edits. The widget installs as a theme app extension, matches your store's look, and pre-selects the recommended size on add to cart.
