Twitter / X Aspect Ratio Calculator
Use this calculator to match current Twitter/X image and video shapes. It helps prevent unwanted cropping in timelines and profile areas.
Twitter and X queries still coexist in search behavior, so this page supports both naming patterns. In practical workflow terms, tweet images, videos, and headers each use different dimensions and should be prepared independently.

Tips for Better Twitter / X Publishing
- Design single-image tweets at 16:9 for predictable desktop and mobile rendering.
- When posting multi-image threads, test crops because layout behavior varies by image count.
- Leave generous side margins in headers to reduce clipping across screen widths.
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.
