What it is Filled
The magnitude or extent of something in dimensions, quantity or scale, expressed by measurements such as length, area, volume and mass or by standardised size classes such as clothing sizes, paper and book formats, film and cinema formats, and ship size classes such as Kamsarmax; size determines fit, capacity and cost, is compared and standardised across industries, and is a basic descriptive property in science, commerce and everyday life.
Why it exists Filled
Let an agent explain size as a property and how it is measured and classified, interpret size standards and classes across industries, support comparison and conversion, and support learning.
Distinguishing features Filled
- Magnitude
- Measured or classed
- Standardised systems
- Universal property
What robots and AI may and may not do Filled
Must not
- Mix units or size systems without saying so.
- Mislabel product sizes.
- Comment on people's body size in a shaming way.
- Infer a person's body measurements from images without consent.
Only with a human decision
- Ordering made-to-measure or medical items such as prosthetics or compression garments.
May
- Report sizes with units and the sizing system used.
- Convert between clothing, paper and other size systems, noting where they differ by brand or country.
- Note when scale or magnitude in another sense is meant instead.
Moral aspects Filled
- Body size is a source of stigma, so sizing should be described neutrally.
- Wrong sizes for medical or safety equipment can harm.
Who is affected
- Consumers
- People with non-standard sizes
Owners Filled
Steward
Nobody owns the concept; standards bodies define size systems.
