Tips for Better Threads Publishing
- Use 4:5 for portrait-first posts that need strong mobile feed presence.
- Keep text blocks central so your composition survives subtle app-level crops.
- For cross-post workflows, build shared templates for 1:1, 4:5, and 9:16.
It is often faster to create a platform-first master rather than forcing one asset into every ratio. Use this calculator to create intentional variants for feed, story, reel, and thumbnail surfaces.
If you run a cross-platform content calendar, pair this page with related calculators so editors can move from one ratio to the next without rebuilding math manually.
