The fullName read-only property of the FontData interface returns the full name of the font face. This is usually a human-readable name used to identify the font, e.g., "Optima Bold".

Examples include:

• Apple SD Gothic Neo UltraLight
• Arial Black
• Avenir Next Heavy
• Katari Medium Italic
• YuMincho +36p Kana Extrabold

A string.

The following snippet will query for all available fonts, and log metadata. This could be used, for example, to populate a font-picker control.

async function logFontData() {
  try {
    const availableFonts = await window.queryLocalFonts();
    for (const fontData of availableFonts) {
      console.log(fontData.postscriptName);
      console.log(fontData.fullName);
      console.log(fontData.family);
      console.log(fontData.style);
    }
  } catch (err) {
    console.error(err.name, err.message);
  }
}
