Google Fonts is a great resource for adding beautiful fonts to your website. Adding fonts to a Gatsby project is as easy as installing the gatsby-plugin-google-fonts plugin:

npm install gatsby-plugin-google-fonts --save

Then, add your favorite fonts to your gatsby-config.js file:

module.exports = {
  siteMetadata: {
    title: `I like Google Fonts`,
  },
  plugins: [
    {
      resolve: `gatsby-plugin-google-fonts`,
      options: {
        fonts: [`Roboto:300,300i,400,400i,700`],
        display: "swap",
      },
    },
  ],
};

In the example above, I am using display: swap. The font-display property defines how font files are loaded and displayed by the browser. swap tells the browser to use the fallback font to display the text, until the custom font has fully downloaded (aka "flash of unstyled text").
