What image dimensions should I use for WordPress themes?

Optimal image dimensions depend on your theme and layout requirements:

  • Featured images: Usually 1200x628px (standard social sharing size)
  • Blog thumbnails: 300-400px width
  • Header images: Full width (1920px) with appropriate height
  • Logo: 200-400px width, maintaining aspect ratio

To manage multiple image sizes effectively, use the Regenerate Thumbnails Advanced plugin. This tool helps create and manage custom image sizes and regenerate thumbnails when needed.

WordPress 6.0+ includes improved image scaling and cropping tools in the Media Library. Remember to:

  • Define custom image sizes in your theme
  • Use responsive images for different screen sizes
  • Consider retina displays (2x resolution)
