I am using the marvelouse react-icons package (, specifically the font awesome package.

If this was not react, then I would just add an attribute to the tag, such as:

<i class="fa fa-camera-retro fa-5x"></i> 

However, if I add the fa-5x to the FaFolderOpen tag, it does not do anything. As you can see, I am using react-bootstrap, and placing the icon a button (should it be a block)?

I have to believe this has been asked before, but I did not find it via search.

Here is what it looks like, and I want it larger:

const React = require('react')
import { Form, FormControl, FormGroup, ControlLabel, Col, Button, Tooltip, OverlayTrigger } from 'react-bootstrap'
import FaFolderOpen from 'react-icons/lib/fa/folder-open'
import FaFileCodeO from 'react-icons/lib/fa/file-code-o'
import FaFolderOpen from 'react-icons/lib/fa/folder-open'
import FaFileCodeO from 'react-icons/lib/fa/file-code-o'

<Button type="button" bsStyle="success" block onClick={(e) => folderChooser(e)}>
     <FaFolderOpen />

if you want a 5x icon size you need to pass it to the react class as size

// Font awesome pixel sizes relative to the multiplier. 
// 1x - 14px
// 2x - 28px
// 3x - 42px
// 4x - 56px
// 5x - 70px

<FaFolderOpen size={70} />

if you notice it jumps by 14 each time

from the github readme it shows everything is overridden inline. its rendering a svg so you cant use 5x you have to use a pixel size


Coming back to this a few years later, with newer versions of FontAwesome/ReactIcons the recommended way to handle different sizings is with their icon provider that utilizes the React Context API. This requires React v16.3+

import { IconContext } from "react-icons";

<IconContext.Provider value={{ className: "shared-class", size: 70 }}>
    <FaFolder />
    <FaBeer />

In reactjs you can use size = 'with your preferred size which be from sm to lg or 1x to 10x'

this is example for font awesome 5 in react

<FontAwesomeIcon icon={faBars} size = '10x'/>

If you need to style several icons simultaneously, you can wrap them to IconContext.Provider.

<IconContext.Provider value={{color: 'navy', size: 42}}>
   <FaFacebook />
   <FaGithub />
   <FaLinkedin />

An approach that is not very explicitly comes from docs (close to @Raimo Haikari):


import {IconContext} from "react-icons";
import { FaBeer } from 'react-icons/fa';
import './App.css'

class App extends component {

return (
    <IconContext.Provider value={{ className="myReact-icons"}}>
      <FaBeer />


.myreact-icons {
  color: red;
  height: 2em;

You can use this:

<FaFolderOpen size="4x" />
