Hi @EB79. Thanks for being part of GoDaddy Community! If you're using the new Website Builder, then there isn't a way to change the font size for any of your text. However, it sounds like maybe you're just using a content section to describe products instead of a product description that would be part of an Online Store product. You might want to try using different sections in order to find one that works best for what you're trying to do. Hope that helps. If not, feel free to provide more information. Others in the community may be able to provide you with additional suggestions.
