Quick answer
Aspect ratio is the relationship between width and height. It matters because a platform can resize pixels, but it cannot magically fix a composition that was designed for the wrong shape. If you design a wide banner and force it into a vertical Story, the important content will either shrink or get cropped.
Square crops are flexible and easy to reuse. Portrait 4:5 crops take up more mobile screen space while still feeling like a feed post. Landscape 16:9 is the standard for video thumbnails and many link previews. Vertical 9:16 is the full-screen mobile format used by Stories and short-video covers.
A strong workflow is to create one high-resolution master image, then produce separate crops for each channel. That keeps every version intentional and avoids awkward automatic cropping.
Recommended workflow
- Start with the largest clean source image you have.
- Choose the exact destination size before adding final text.
- Crop visually so the subject, logo, and key message stay inside the safe area.
- Export in JPG for photos, PNG for crisp graphics, or WebP for web use.
Checklist
- Pick the ratio before adding text.
- Keep faces and product details inside safe areas.
- Export separate crops for different platforms.
- Use 9:16 for full-screen mobile placements.
