Social Media Character Counter

Paste a title, caption or post and see instantly whether it fits YouTube, TikTok, Instagram, Facebook, Pinterest, LinkedIn, X and Google search results – including how much shows before the “more” cut-off. It also flags ALL CAPS, missing hooks and hashtag overload. Free, and it runs entirely in your browser.

Paste it exactly as you will publish it. The first line matters most - it is what people see before "more".

    Fits? And what shows before the cut-off

    Platform · fieldUsed / limitStatus

    Visible part on a phone (approx.)

    Nothing leaves your browser. Limits are the platforms' published maximums; "visible" lengths are typical and vary by device, font and layout. Checked 25 September 2026.

    Why the first line matters most

    Every platform truncates. YouTube titles are cut off on phones, Instagram shows only the first line or two of a caption, and Google trims long titles in search results. The counter shows the visible part for each, so you can put the words that earn the click where people will actually see them.

    Good to know

    • Limits and visible lengths are based on the platforms’ published maximums and typical display, and platforms change them. Treat the “visible” figure as a guide.
    • Emoji and some symbols count as more than one character on some platforms.

    How long can a YouTube title be?

    YouTube allows up to 100 characters, but on phones only roughly the first 50-60 are visible, so put the key words first.


    How long can an Instagram caption be?

    Up to 2,200 characters, but only the first line or two show before “more”. Treat the first line as the headline.


    Does my text get uploaded?

    No. The counter runs in your browser and nothing you type is sent anywhere.
