How this checker works

Every limit on this page comes from a single canonical file (platform-limits.json) verified against the platform's own documentation. When a platform changes a limit — like TikTok's 2,200 → 4,000 caption bump in 2023 — it updates in one place and every tool on WordTally reflects the change.

This page is for writers and social media managers who post to multiple platforms and need to know which ones they'll fit in before they publish. For a single platform, jump to the dedicated tool with extra tips and examples.
