## Definition

the idea that two things should match each other in size or amount. You use it when a punishment, rule, or cost should be fair for the situation.

For teachers: a relationship in which two amounts change together in a balanced way; by extension, the principle that an action or punishment should match the size or seriousness of the situation it responds to.

## Examples

- The punishment lacks proportionality to the small mistake.
- The court checks the proportionality of the fine to make sure it fits the offence.
- Debates about proportionality in sentencing ask whether long prison terms for minor theft truly match the harm done to society.
