## zh-CN

三种大小的输入框，若不设置，则为 `middle`。

## en-US

The input box comes in three sizes. `middle` will be used if `size` is omitted.

```tsx
import React, { useState } from 'react';
import { DatePicker, Radio, Space } from 'antd';
import type { RadioChangeEvent } from 'antd';
import type { SizeType } from 'antd/es/config-provider/SizeContext';

const { RangePicker } = DatePicker;

const App: React.FC = () => {
  const [size, setSize] = useState<SizeType>('middle');

  const handleSizeChange = (e: RadioChangeEvent) => {
    setSize(e.target.value);
  };

  return (
    <Space direction="vertical" size={12}>
      <Radio.Group value={size} onChange={handleSizeChange}>
        <Radio.Button value="large">Large</Radio.Button>
        <Radio.Button value="middle">middle</Radio.Button>
        <Radio.Button value="small">Small</Radio.Button>
      </Radio.Group>
      <DatePicker size={size} />
      <DatePicker size={size} picker="month" />
      <RangePicker size={size} />
      <DatePicker size={size} picker="week" />
    </Space>
  );
};

export default App;
```
