What Changed in 2026

Instagram officially shifted from its iconic square grid to a 3:4 (taller) grid format in late 2025. This change is permanent in 2026. The new 1080 × 1440px format maximizes vertical space and aligns with how users consume content on mobile. Square posts (1080×1080) are still supported but appear letterboxed in the grid. For best results, design for 3:4 ratio moving forward.

Avoid Compression

Instagram compresses images aggressively. To minimize quality loss:

  • Upload at exact recommended dimensions (don't rely on Instagram to resize)
  • Use JPEG quality 90–100% before uploading
  • Upload at 2× resolution when possible (e.g., 2160×2880 for 3:4 posts)
  • Avoid highly detailed textures and gradients

Supported Formats

Instagram accepts the following file formats:

  • Images: JPEG, PNG (PNG converted to JPEG on upload)
  • Video: MP4, MOV
  • Codec: H.264 (video), AAC (audio)
  • Frame Rate: 30 FPS max (60 FPS for Reels)

Best Practices

Maximize engagement with proper sizing:

  • Use 3:4 (1080×1440) for new posts to align with 2026 grid
  • Stories: keep critical content in the center 1080×1420 zone
  • Profile photo: upload at 800×800 minimum for Retina clarity
  • Test on mobile before posting — Instagram is mobile-first
