About
Foot Size Check measures feet with nothing but a sheet of A4 paper and a photo.
Kids' feet grow fast. Place a foot on A4 paper, take a photo from directly above, and get foot length, width, and a suggested shoe size (JP sizing) right away.
Features:
- A4-paper-based foot measurement (length and width)
- Suggested shoe size estimates
- Growth history saved over time
- Track left and right feet separately
- Fine-tune measurement points by hand
- No account, no upload, no ads - photos and records stay on your device
Note: results are estimates only. Shoe fit varies by brand, model, and foot shape. We recommend measuring in person before buying shoes.
