TikTok profile specs
TikTok's bio is the shortest of the major platforms at 80 characters, and usernames are capped at 24. The profile picture is shown very small, so a monogram or simple mark works far better than a photo with detail.

Where it usually goes wrong
- A bio written for Instagram — it's cut at 80 characters here
- A profile picture with fine detail; it's displayed at roughly 100 px
- A username with a period at the end; TikTok doesn't allow it
Skip the guesswork
SetMySocial writes your TikTok bio to exactly 80 characters, checks whether the username is free, and exports the picture at the right size.
