Is there a limit to the number of tags Tumblr can remember?

Question

I maintain a comic book Tumblr, where I post the covers to every comic book that I read and other assorted comic book ramblings. I tag every post with the series name, writer, artist, publication company and publication year. Recently, newer tags (like iZombie and 2012) don't get remembered when I go to add them in the tag field when posting new issues. They still work like tags when published, but I have to type them out every time instead of having Tumblr autofill like it does with every other tag I've used up to a few weeks ago.

Is there a limit to the number of tags Tumblr can remember and autofill? And if so, is there a way around it?

Answer 1

Here's the official response from Tumblr support:

Beth, Nov-16 13:33 (EST): Hello,

If you are using a substantial number of tags on your posts, you may find that Tumblr doesn't show all of them in saved tags lists. The list may be shortened in order to ensure the pages where you create and edit posts load quickly.

You can still use as many tags as you wish. But, you will need to fully type out any tags that aren't displayed in the saved tags list. Our apologies for any inconvenience this might cause.

Please let us know if you have any other questions.

Thanks, Beth Tumblr Support support@tumblr.com

So it is expected behaviour, but no mention of what the hard limit is though.

Update from Renee in Tumblr support:

The hard limit for tag autocompletion is "closer to around 100 actually."

Answer 2

Yes, there is a tag limit in tumblr. The limit is of 199 tagged posts. You can use a tag for only 199 times! After the 200th use, the oldest post will not appear when is searched. There is also a tag limit of 30 tags per post!
