What image dimensions should I use for WordPress?

Optimal image dimensions depend on your theme and layout, but here are general guidelines:

  • Featured images: 1200x628px (social sharing optimal)
  • Blog post images: 800-1200px width
  • Thumbnails: 150x150px
  • Header images: 2000px width maximum

Use the Regenerate Thumbnails plugin to resize existing images to new dimensions. Also, consider your theme’s specific requirements and responsive breakpoints when choosing dimensions.
