The face-first square
Profile photos exist to make you recognizable at a glance — 400px holds clear facial detail while platforms render it down to chat-bubble size. Tight framing (head and shoulders) is what survives that whole range.
One headshot, everywhere
A well-framed 400×400 headshot serves social profiles, professional networks, team pages and app accounts identically — the personal-brand master square.
