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 { Button } from 'antd';

ReactDOM.render(<div>
  <Button type="primary" size="large">Large</Button>
  <Button type="primary">Default</Button>
  <Button type="primary" size="small">Small</Button>
</div>, mountNode);
