Platform support

Post types and limits, network by network

Every network sets its own rules — X caps posts at 280 characters while Facebook allows over 63,000, Instagram carousels hold ten images and TikTok holds thirty-five. The table maps what each major platform supports and what Kadenzo schedules on your behalf, so you know a post will fit before you write it.

Limits and supported formats are set by each platform and can change; we keep this table current. A dot means Kadenzo can schedule it; a label notes the limit or format.
