Hashtag limits on each network

What each network says on its own pages, with the date we read it.

Where we found no official limit, hashtags still count toward the caption's length. X's help page now asks every visitor to prove they're human before it opens, so its row is from our check on 25 October 2026.

Why some sites still say 30

On 18 December 2025, Instagram's Creators account announced that Instagram would allow up to 5 hashtags in a Reel or post, and its Help Center now says the same. Meta's developer page for apps still lists 30, and many guides and tools repeat that number. Unisenda's composer uses 5. For the whole story, see how many hashtags to use on Instagram.

Hashtags everyone can read

• Give each word a capital: #SmallBusinessTips, not #smallbusinesstips. Screen readers can read a run of words as one long word; with capitals, they say each word.
• Use letters, numbers and underscores. On Instagram and Facebook, punctuation and symbols such as $ and % end a hashtag.
• Put hashtags on the caption's last line, so the first words people read are yours, not a list of tags.
• In Unisenda, each account gets its own caption, so Instagram can have 5 hashtags while X gets 1 and LinkedIn none.
