Frequently asked questions

How often do social media image sizes change?

Platforms typically update their recommended dimensions once or twice a year. We monitor changes and update this guide accordingly. The current sizes reflect specifications as of early 2026.

What happens if I upload the wrong size?

Most platforms will automatically crop or letterbox your image to fit. This often means important parts of your image get cut off or the quality is reduced. Using the correct dimensions avoids these issues.

Should I use PNG or JPG?

Use JPG for photos and images with many colors. Use PNG for graphics with text, logos, or transparency. WebP offers better compression than both for web use.
