Thread questions answered

What is the character limit per tweet / X post?
Standard X (Twitter) accounts are limited to 280 characters per post. X Premium subscribers can post up to 25,000 characters in a single post.
How does the thread splitter decide where to break posts?
It first tries to break on paragraph boundaries (blank lines). Within long paragraphs, it breaks at sentence endings. If a single sentence exceeds 280 characters, it splits at the nearest word boundary.
Should I add post numbers to my thread?
It depends on the thread length. For threads of 5+ posts, numbering (1/7, 2/7…) helps readers understand the structure and length. For shorter threads of 2–3 posts, numbering is optional.
Can I post threads directly from Postlia?
Yes — Postlia's posting product (coming soon) lets you write a thread once and publish it directly to X, LinkedIn, and other platforms on a schedule.
Does this tool work for Bluesky threads?
Bluesky's limit is 300 characters, slightly higher than X's 280. This tool uses 280 characters as the safe default. All posts produced will comfortably fit in a Bluesky thread as well.
