Adding custom fonts

For Rails 4.1 and higher.

Create a folder name fonts inside the app/assets directory and place custom fonts inside this new folder. The folder structure should now look like app/assets/fonts.

Add this line to config/application.rb:

config.assets.paths << Rails.root.join("app", "assets", "fonts")

Rename app/assets/stylesheets/application.css to app/assets/stylesheets/application.css.scss. Place your font css code into this file. An example below shows you what the structure would look like.

You can cut and paste this example code but remember to replace custom-font-name with your font name. And change the font-family name to the font name of your choosing:

@font-face {
    font-family: 'Custom Font Title';
    src: url(asset-path("custom-font-name.eot"));
    src: url(asset-path("custom-font-name.eot?#iefix"))  format("embedded-opentype"),
          url(asset-path("custom-font-name.woff2")) format("woff2"),
          url(asset-path("custom-font-name.woff")) format("woff"),
          url(asset-path("custom-font-name.ttf")) format("truetype"),      
          url(asset-path("custom-font-name.svg#custom-font-name")) format("svg");
    }

Now add fonts to config/initializers/assets.rb to precompile additional assets.

Dir.glob("#{Rails.root}/app/assets/fonts/**/").each do |path|
    Rails.application.config.assets.paths << path
end

Then restart the web server and test.

$ bundle exec rails s
