About RingSizer

Remove sizing doubts for your customers to impact your sales and returns

RingSizer helps your customers find their ideal ring size. Sizing uncertainty is one of the main reasons for cart abandonment and returns for jewelry merchants. Our app adds a “Find My Size” button to product detail pages, allowing your customers to easily measure their fingers or an existing ring directly from their phone. Co-developed with jewelers, we use machine learning for size prediction. Install effortlessly without a developer; it blends seamlessly with your store’s theme and brand.

  • Measure anywhere: Guided measurement of finger or rings using a phone
  • Reliable: Built and calibrated to work across different body types
  • Plug-and-play: Easily integrate RingSizer into your store design
  • International: Built-in conversion and size charts for common scales
  • Size matching: Measurements are automatically matched to closest in-stock sizes
