Fun Facts

  • The word 'avatar' in computing was first used by Chip Morningstar and Randall Farmer in Lucasfilm's Habitat (1986), a pioneering online multiplayer environment.
  • Gravatar (Globally Recognized Avatar), launched in 2004, generates default avatars from email hashes — it serves over 100 billion avatar requests per year as of 2023.
  • The standard avatar size in most design systems is 40px for inline mentions, 48px for list items, and 80-120px for profile headers — a convention established by early social networks.

FAQ

What fallback when an image fails?
Initials (first + last name letters) rendered in a colored circle. The background color is derived from a hash of the name so it's stable per person.
Does it support circular and square shapes?
Yes — toggle border-radius between 50% (circle), 20% (squircle), and 0% (square). Combine with a colored ring for status.
How are initials calculated?
First letter of first name + first letter of last name, uppercase. For single-word names, the first two letters are used.
Is the output responsive?
Size is set via a CSS variable so you can resize by updating `--avatar-size`. Font size scales proportionally.
