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.
