Type or paste once and watch every platform limit at the same time — bios, captions, posts and titles, with emoji counted the way platforms count them.

Instagram gives you 150 characters for a bio and 2,200 for a caption — but only the first ~125 caption characters show before the “more” fold, so front-load the hook. X posts stop at 280. TikTok bios are a tight 80 characters while captions stretch to 4,000. YouTube truncates titles around 70 characters in search results even though the hard limit is 100. LinkedIn headlines allow 220, and Threads posts cap at 500.
An emoji like 👩👩👧👦 is a single character to a person but up to eleven code units to a naive counter — which is how a bio that “fits” gets cut off mid-emoji when you paste it. This counter uses grapheme segmentation, the same user-perceived-character logic platforms use, so what fits here fits there.
A limit is an editing tool. The 150-character bio format that consistently works: who you help + how + proof or personality, one line each. For captions, say the important thing in the first sentence and let the rest be depth for people who tapped “more” — the fold decides your reach, not the total length.
Yes — every platform counts spaces and line breaks as characters. This counter does too.
Yes. Hashtags are ordinary text inside Instagram's 2,200-character and TikTok's 4,000-character caption limits. Instagram additionally caps you at 30 hashtags per post regardless of characters.
X wraps every URL in its t.co shortener, which always costs a flat 23 characters no matter how long the original link is. Budget 23 for any link you include.
Yes, the limits are global — but scripts differ in density. 80 characters of Japanese says far more than 80 characters of English, which is why the same TikTok bio can be roomy in one language and impossible in another.
