Short answer
When designing physical products, use percentile data (e.g., 5th and 95th) to define critical dimensions, ensuring a broad range of users can interact with the product comfortably and effectively.

Utilizing percentile-based anthropometric data, specifically the 5th percentile female and 95th percentile male, can ensure that product dimensions accommodate approximately 90% of a target population. This human factors research insight is drawn from a 2014 study published in Knee Surgery Sports Traumatology Arthroscopy. Using Literature review and data analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing physical products, use percentile data (e.g., 5th and 95th) to define critical dimensions, ensuring a broad range of users can interact with the product comfortably and effectively.

Key Findings
- 01Anthropometry is essential for optimizing product development across various design fields.
- 02Different populations exhibit distinct anthropometric characteristics.
- 03Designing for the 5th percentile female and 95th percentile male accommodates approximately 90% of a population.
Application
Design takeaway
When designing physical products, use percentile data (e.g., 5th and 95th) to define critical dimensions, ensuring a broad range of users can interact with the product comfortably and effectively.
How to apply
When designing any physical product, research the relevant anthropometric data for your target demographic and use percentile ranges to inform key dimensions like height, width, and grip diameter.
Project actions
- 01Identify the primary user demographic for your design project.
- 02Research available anthropometric data for that demographic.
- 03Select appropriate percentiles (e.g., 5th and 95th) to define critical dimensions.

Strengths & Limitations
Strengths
- +Provides a quantitative basis for design decisions.
- +Promotes inclusive design practices.
Limitations
Access to specific, up-to-date anthropometric data for niche populations can be challenging.
Reliability & validity
The reliability of anthropometric data depends on the study's methodology and sample size. The validity of applying percentile data to design relies on accurate data collection and appropriate selection of percentiles for the target user group.
Think critically
While designing for the 5th and 95th percentiles accommodates a large majority, what are the ethical considerations for the remaining 10% of the population, and how might a designer address their needs?
Design Principles
"Design for the extremes of human variation within a population to maximize inclusivity."
This approach to design is crucial for creating products that are broadly usable and comfortable, reducing the likelihood of exclusion for a significant portion of the user base. It moves beyond average measurements to consider the extremes of human variation, leading to more universally applicable designs.
What This Means for Your Design
To make sure most people can use something you design, look at the measurements of the smallest and biggest people in the group you're designing for. Using these extreme measurements helps make sure about 90% of people will find it fits them.
How to use in your project
- 1.Reference anthropometric data and percentile calculations when justifying design choices for physical product dimensions.
- 2.Explain how your chosen dimensions accommodate a specific percentage of the target population.

Paragraph starter
The design of physical product dimensions was guided by anthropometric data, specifically employing the 5th percentile female and 95th percentile male measurements. This approach ensures that approximately 90% of the target population can comfortably and effectively interact with the product, moving beyond average measurements to accommodate a wider range of user sizes.
