Foot Size Check

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 Foot Size Check Pro (optional one-time purchase): - Same-age reference band on the growth chart (by sex; published survey data from Japan, Spain, or China) - Register more than one child (siblings; one is free) - Measuring, records, the chart, and shoe notes stay free. Not a subscription Note: results are estimates only. Shoe fit varies by brand, model, and foot shape. We recommend measuring in person before buying shoes.
