What is ISO 8559-1:2017 Size Designation of Clothes?
In an industry where standardization is pivotal for global trade, consumer trust & manufacturing consistency, ISO 8559-1:2017 – Size Designation of Clothes emerges as a vital benchmark. Designed by the International Organization for Standardization, this standard establishes the body measurement system used for clothing size designation. It serves as a foundation for consistent, clear, and globally recognized sizing systems.
What is ISO 8559-1:2017 Size Designation of Clothes?
ISO 8559-1 outlines principles and practices for the size designation of clothes, based on body measurements. It is part of a broader set of standards under ISO 8559, which collectively address clothing sizes and anthropometric data. This part specifically focuses on the body measurement system and not the garment dimensions themselves.
The goal of this standard is simple yet powerful—create a uniform approach to clothing size labelling that enhances transparency for consumers and improves efficiency for manufacturers and retailers alike. Whether you’re a global fashion brand or a local clothing line, aligning your sizing systems with ISO 8559-1 ensures that your product labeling resonates accurately with customer expectations and fits.
Why ISO 8559-1:2017 is Crucial for the Clothing Industry
The textile and fashion industries are heavily influenced by regional sizing preferences and body morphology. Mislabeling or inconsistent sizing leads to increased return rates, dissatisfied customers, and higher operational costs. ISO 8559-1 eliminates confusion by offering a standardized approach that bridges these variations and supports international commerce.
From a business standpoint, this standard:
- Supports consumer rights by offering truthful size information.
- Enhances interoperability in global supply chains.
- Reduces product returns due to improper fits.
- Improves e-commerce performance, where customers rely solely on sizing charts.
Requirements of ISO 8559-1:2017 Size Designation of Clothes
To achieve compliance with ISO 8559-1:2017, organizations must meet the following key requirements:
Defined Body Measurement System
The standard defines primary and secondary body dimensions used for various clothing types. For example, chest girth, waist girth, and stature are critical for determining upper body garment sizes.
Clear Labelling Protocol
Size designation must be clear, logical, and linked to specific body measurements, not arbitrary alphanumeric sizes. Labels should include metric dimensions (centimeters) for clarity.
Target Population Consideration
Brands must account for the anthropometric characteristics of their target population when implementing sizing charts. The standard encourages the use of body measurement surveys and statistical data.
Consistency Across Garment Categories
Consistency in size designation should be maintained across all clothing types—tops, bottoms, dresses, outerwear, etc. This ensures uniform consumer experiences across the product line.
Gender and Age Group Segmentation
Size charts must be differentiated by gender (male, female, unisex) and age group (infant, children, adults). ISO 8559-1 provides structured templates for such segmentation.
