Camera-based head measurement and size recommendations for helmets, hats and fitted caps.
Sizing uncertainty stops headwear shoppers from buying or leads to bracket orders and returns. TWIWT gives them clarity directly on your product pages. Shoppers measure their head using a phone or laptop camera without a measuring tape or reference card. The widget matches their measurement to your configured size chart and recommends a size. Designed for hats, helmets and caps, it runs in-browser with zero downloads.
- Shoppers measure with a camera, no measuring tape or reference card needed
- Matches customer measurements to the size chart configured for each product
- Embedded widget runs instantly on product pages with no app download
- Helps shoppers choose a size when sizing uncertainty would delay the order.
- Displays measurements in centimetres or inches according to store preferences.
