## en-US

There are three sizes available to a numeric input box. By default, the size is `32px`. The two additional sizes are `large` and `small` which means `40px` and `24px`, respectively.

```jsx
import { InputNumber } from 'antd';

function onChange(value) {
  console.log('changed', value);
}

ReactDOM.render(
  <div className="site-input-number-wrapper">
    <InputNumber size="large" min={1} max={100000} defaultValue={3} onChange={onChange} />
    <InputNumber min={1} max={100000} defaultValue={3} onChange={onChange} />
    <InputNumber size="small" min={1} max={100000} defaultValue={3} onChange={onChange} />
  </div>,
  mountNode,
);
```

```css
.code-box-demo .ant-input-number {
  margin-right: 10px;
}
.ant-row-rtl .code-box-demo .ant-input-number {
  margin-right: 0;
  margin-left: 10px;
}
