Impulse Support: How do I add custom fonts?

If you're not comfortable making code changes to your theme, we highly recommend using one of our partners who specialize in adding custom fonts to your shop. Our support is limited to this guide.

With some custom code you can add your own fonts to our themes. These fonts will not appear in the theme editor as a dropdown option, but instead override the values directly in the stylesheet.

1. Generate your font and style files

Upload your custom font files to Font Squirrel with this tool. TTF file types have the best success. Then click the Download your kit button to get a zip file with the required files.

Fonts must have a valid license to use on the web

2. Add the font files to your theme

First, open up your Shopify admin (navigate to /settings/files, click Upload files and upload the individual files.

3. Edit your theme's code

This information is for version 3.2.0 and newer.
Scroll down to see steps for older versions of Impulse.

Look for an open css-variables.liquid inside your snippets folder.

Add this code on the first line after the {% style %} tag:

@font-face {
  font-family: "MyFont";
  src: url('{{ "font_myfont.woff2" | file_url }}') format("woff2"),
       url('{{ "font_myfont.woff" | file_url }}') format("woff");

You can set the headings and body fonts by changing these two lines:

--typeHeaderPrimary: {{ }};
--typeBasePrimary:{{ }};

to match your newly created font:

--typeHeaderPrimary: 'MyFont';
--typeBasePrimary: 'MyFont';

You'll also want to adjust a few other lines in this file. The following lines previously used your theme settings to set the style and font weight. Similar to above, you'll want to change these values according to your newly added font.

--typeHeaderWeight: {{ settings.type_header_font_family.weight }};
--typeBaseWeight: {{ settings.type_base_font_family.weight }};

The above would change to something like:

--typeHeaderWeight: 700;
--typeBaseWeight: normal;
For versions before 3.2.0 (July 2020), .

Look for and open theme.scss.liquid inside your assets folder. At the top of the file, add this code:

@font-face {
  font-family: "MyFont";
  src: url('{{ "font_myfont.woff2" | asset_url }}') format("woff2"),
       url('{{ "font_myfont.woff" | asset_url }}') format("woff");

Change the values in bold to what matches the files you generated earlier.

Now that you have your font files loaded and its name, you're ready to integrate it with your theme's stylesheet.

Find theme.scss.liquid in the assets folder and then search for this line of code with command + f on Mac and control + f on Windows:

/*================ Global | Normalize ================*/

Add these two lines below it, replacing the font-name with your newly uploaded font.

$type_base_stack: 'MyFont', sans-serif;
$type_header_stack: 'MyFont', sans-serif;

Use sans-serif or serif as the fallback depending on your font style. You can set both lines to use the same font-name if you only add one.
