Full title and description

STB BS ISO 19407-2023 — Footwear — Sizing — Conversion of sizing systems. International standard providing standardized conversion tables and guidance for translating between the main shoe-size systems (Mondopoint, European, United Kingdom, United States, China, Japan and the Republic of Korea), intended to support manufacturers, retailers and regulators in consistent size marking and consumer information.

Abstract

This standard specifies three shoe-size conversion tables based on measured foot length: (1) adults' technical shoe size conversion, (2) adults' recommended shoe size marking (simplified), and (3) children's size conversion. The tables are intended as guidance only because historic development and local interpretation of size systems vary; they use foot length as the primary datum for conversion and recommended marking.

Scope

ISO 19407:2023 provides conversion tables and guidance for converting between major footwear sizing systems. It covers adults' technical conversions, simplified recommended marking for adults, and children's conversions. The tables are derived from foot-length measurement as the primary basis for size determination and are intended as practical guidance to assist consumers and supply-chain stakeholders where direct one-to-one equivalence between historic systems does not exist.

Key topics and requirements

• Three conversion tables: adults' technical conversion; adults' recommended (simplified) marking; children's conversion.
• Coverage of sizing systems: Mondopoint, European, United Kingdom, United States, China, Japan, Republic of Korea.
• Use of measured foot length (millimetres) as the fundamental datum for conversion and marking guidance.
• Guidance notes explaining limits of exact equivalence between historic systems and emphasizing the tables as consumer/industry guidance rather than strict technical interchange rules.
• Recommendations for marking practices to improve clarity for consumers when multiple sizing systems are in use.

Typical use and users

Manufacturers and designers of footwear (for labeling and internal specification), retail merchandisers and e-commerce platforms (for size charts and customer guidance), conformity assessment and testing laboratories, national standards bodies and regulators (for harmonization), and consumer-interest organisations concerned with sizing information and comparability.
