Use your own font
Upload a font file and give it a role in Typography.
Shopify's font library covers most needs. When your brand has its own font, you can add it to Rouge without editing code.
Upload the files
Go to Content › Files and upload the font in WOFF2 format, one file per weight.
Pick it in Typography
Open Theme settings › Typography, choose Custom font for the heading or body role, and paste the file links.
Check the weights
Rouge uses a regular, a medium and a strong weight for each role. If a weight is missing, Rouge falls back to the nearest one you uploaded instead of faking it.
