en-US

Ant Design supports a default button size as well as a large and small size.

If a large or small button is desired, set the size property to either large or small respectively. Omit the size property for a button with the default size.

import React, { useState } from 'react';
import { Button, Radio } from 'antd';
import { DownloadOutlined } from '@ant-design/icons';

export default () => {
  const [size, setSize] = useState('large');
  const handleSizeChange = e => {
    setSize(e.target.value);
  };

  return (
    <>
      <Radio.Group value={size} onChange={handleSizeChange}>
        <Radio.Button value="large">Large</Radio.Button>
        <Radio.Button value="default">Default</Radio.Button>
        <Radio.Button value="small">Small</Radio.Button>
      </Radio.Group>
      <br />
      <br />
      <Button type="primary" size={size}>
        Primary
      </Button>
      <Button size={size}>Default</Button>
      <Button type="dashed" size={size}>
        Dashed
      </Button>
