Tumblr username checker for blogs and side blogs

Tumblr is still home to fandoms, artists and writers, and the good blog names are long gone. This Tumblr username checker shows whether tumblr.com/yourname is already a blog before you sign up, rename or start a side blog.

Tumblr names are up to 32 characters using letters, numbers and hyphens. Underscores and periods aren't allowed, so a handle from Instagram may need a small change here.

Check the same name on Instagram, X, TikTok and Pinterest in one search, so your followers can find you wherever they come from.

Tips for a Tumblr name

  • Hyphens are fine; underscores and periods aren't.
  • Puns and references are part of the charm.
  • Match your main blog to your other socials.
  • Use side blogs for fandoms or themes.
  • Check before renaming: your old name is released.

Picking a Tumblr blog name

Tumblr names are part of the culture: puns, fandom references and wordplay are normal, and good ones go fast. Hyphens are allowed but underscores and periods aren't, so a name you use elsewhere may need a hyphen here. Say it out loud before you commit: people will tag you by it.

Side blogs and matching handles

Tumblr lets one account run several blogs, which is handy for art, fandoms or a separate photo blog. Give your main blog the name you use on Instagram, X and TikTok, and use the side blogs for themes, so followers can always find the real you.

Own the name everywhere, not just on Tumblr

A handle only works inside one app. The domain is the part you keep — it carries your site, your email and your link in bio even if you move platforms. Names that are free on Tumblr today are usually free as a .com too, and that stops being true fast.
