Twitter posts — called tweets — are limited to 280 characters, including spaces, punctuation, and symbols. Every URL you include, regardless of its original length, is automatically shortened by Twitter's t.co service and counts as exactly 23 characters. Emoji each consume 2 characters. Use this Twitter Character Counter to draft and measure your tweets in real time: paste your text, check the 280-character progress bar above, and refine until it fits. No sign-up required, and the tool runs entirely in your browser. The Tweet preset is pre-activated below.
