Tips for better X posts
280 char limit
X's limit is 280 characters. Use every character wisely, or embrace brevity.
Hook first
Lead with the most compelling sentence. Most users scroll past without reading more.
Use line breaks
White space makes threads and long tweets easier to read on mobile.
End with a question
Posts ending with a question get significantly more replies and engagement.
Why test your tweet before you post?
A tweet tester shows you exactly how your post will render in the X feed before you publish — where line breaks fall, how much text shows, and how images are cropped. Testing first catches formatting mistakes that are impossible to fix after posting without deleting the tweet.
Unlike drafting inside X, an X post checker lets you iterate freely: adjust your hook, watch the character count, toggle the verified badge, and swap images until the post looks right. Edits on X are locked behind Premium, and deleted tweets lose their replies and engagement — so checking before posting is the safer workflow.
This Twitter post tester runs entirely in your browser. Nothing is posted to X, nothing is saved, and no account is required.
