How to Resize Images for Instagram, WhatsApp & Social Media

Wrong image size means cropped heads and blurry posts. Use the right dimensions for every platform — and resize in bulk.

Every social platform has different aspect ratios. Posting a landscape photo to Instagram Stories adds black bars; uploading a tiny logo as a WhatsApp status looks pixelated. Resizing to platform presets avoids awkward crops.

Common social media image sizes (2026)

  • Instagram post (square): 1080 × 1080 px
  • Instagram Story / Reels cover: 1080 × 1920 px
  • WhatsApp profile photo: 500 × 500 px (displays as circle)
  • Facebook cover: 820 × 312 px
  • Twitter/X header: 1500 × 500 px
  • LinkedIn post: 1200 × 627 px
