What the verdicts mean+
Too short (under 60 chars): often feels low-effort — add substance.
Ideal (60-240 chars): sweet spot. Fits cleanly on every screen.
Approaching limit (240-280 chars): may truncate on small previews. Tighten if possible.
Long-form (280+ chars): Use as a thread (split below) or X Premium long-form post.
Common questions
What is the X (Twitter) character limit?+
280 characters for a standard tweet. X Premium subscribers can post up to 25,000 characters (long-form posts), but these are treated as a separate format by the algorithm. For maximum reach, stay under 280.
Why does my emoji count as one character but it looks bigger?+
X counts characters by graphemes (visible characters), which is Unicode-aware. A single emoji is one character even if it's composed of multiple Unicode code points internally. Compound emojis (like family emojis) also count as one. Our counter uses the same logic.
Why is 240 characters the visibility sweet spot?+
240 chars leaves room for QT (quote-tweet) additions when others share your post — they can add their own text without the original being truncated. Plus, on smaller mobile screens, posts past 240 chars sometimes get cut off in feed previews.
How does the thread-split feature work?+
When you paste content over 280 chars, we split it into tweet-sized chunks at the nearest sentence boundary. If no sentence break is close enough, we fall back to word boundaries. Each chunk targets 240 chars to leave room for thread numbering or signal markers.
