## Definition

the system of standard measurements used to show how big or small clothes and other products are.

For teachers: the classification of items according to a standardized set of dimensions or measurements.

## Examples

- The store changed its sizing for the new summer collection.
- Customers often complain that the sizing of this brand runs smaller than the industry average.
- Global retailers face significant logistical challenges when reconciling inconsistent sizing standards across different international markets, often leading to high rates of product returns.

## Pitfalls

- Not "The sizings are wrong" but "The sizing is wrong" — In the context of a measurement system, the word is uncountable and should not be pluralized.

## Usage notes

- Often used in the context of manufacturing, retail, and garment production.
