## What it is
A small React library that makes components aware of their own rendered width and height, enabling component-level responsive design. It exposes a SizeMe render-prop component and a withSize higher-order component that report element size changes.

## Use cases
- make a react component responsive to its own container size
- render different child components based on element width
- get element width and height in react
- component-level element queries in react
- swap layouts depending on available space in react
- measure a react component's size on resize

## When to choose
- you need components that adapt to wherever they are rendered, not just the viewport
- you want a tiny, performant size-awareness utility with render prop or HOC APIs
- you need broad browser support and SSR compatibility

## When to avoid
- you only need viewport-based responsive design - CSS media queries suffice
- you're starting a new project and prefer actively maintained alternatives like ResizeObserver hooks
- you need container query support natively available in modern CSS
