Character Limits

This tag covers the character limits, truncation behavior, and formatting conventions PostRSS's supported platforms each enforce, and how to template around them from a single RSS source. It walks through X's strict 280-character limit, Facebook and LinkedIn's effective truncation points despite much higher technical limits, and Pinterest's search-oriented description field, which behaves more like SEO copy than social copy. Articles here focus on building platform-specific templates rather than reusing one generic block of text everywhere. This tag pairs with platform-formatting and templates for the practical setup side of the same problem. It's a useful reference before writing or revising any PostRSS post template.
