Do hashtags and mentions count in a caption?

They are part of the caption text, so the counter includes their letters, symbols and spaces. Line breaks also remain in the total.

Is this an Instagram bio character counter?

The selected preset is for a caption, not a bio. You can count the visible characters in any pasted text, but do not use the caption’s 2,200-character reference as a bio limit.

How are emoji counted here?

The Characters figure counts visible grapheme clusters, so a joined family emoji is one visible character. UTF-16 units and code points are shown separately. A platform can use a different counting convention, which is why the caption preset is a guide.

Can I count Instagram words or use the tool on a phone?

Yes. Paste the caption in a modern mobile browser to see words and character totals. It does not connect to Instagram or publish the caption.

Instagram Caption Character Counter

Draft an Instagram caption with the caption preset selected. It compares the visible-character total with a 2,200-character reference and keeps word count, UTF-16 units and UTF-8 bytes visible. Hashtags and @mentions are part of the text. Treat the remaining figure as a drafting guide and use Instagram’s editor for its final validation.

What a character is here. Characters are counted as visible Unicode grapheme clusters, with UTF-16 units, code points and UTF-8 bytes shown separately. X uses weighted length and SMS uses encoding-based segments. Other preset limits are visible-character drafting guides; the destination platform decides what fits.

Preset limits

X uses weighted length and SMS uses encoding-based segments. The other presets compare visible characters with a drafting limit; the destination may count differently. Track one to see the room left under that check.

X postLatin counts 1, CJK and emoji count 2, and any link would count 23.

Keyword density

The words used most, as a share of every word in the text. A short list of stop words such as the, and, of and to is left out, so the terms you are actually writing about come to the top.

Write a sentence or two and the words you lean on most appear here.

Character and letter frequency

The 100 most frequent entries, with counts and percentages. Letters are normalized and folded to lower case; All characters keeps case, emoji, digits, punctuation and whitespace. Character order preserves case in All characters mode.

No letters yet.

Nothing you paste leaves this tab. The counting runs in the page itself, so a draft, a client brief or an unpublished post is only ever on your machine. There is no size limit either: the practical ceiling is your own memory.
