What Size Should Instagram Photos Be: A Practical Guide to Image Dimensions

Use these dimension templates as your baseline. Square posts work in nearly all contexts, while portrait and landscape suit different placements. For best sharpness, match native aspect ratios and export at the target size without upscaling.

FormatPixel Dimensions (1:1)Aspect RatioTypical Use
Feed Square1080 × 10801:1Profile grid posts
Feed Portrait1080 × 13504:5Single image posts
Feed Landscape1200 × 6281.91:1Shared or external links preview

Feed Square, Portrait, and Landscape

For static feed images, 1080 × 1080 pixels (1:1) is the safest default. It displays sharply on retina screens and remains centered in the grid. If you prefer a taller composition, 1080 × 1350 (4:5) fits well within the feed without cropped edges. For landscape shared or external-link previews, 1200 × 628 maintains clarity in link cards and timelines. Export at 72 PPI; Instagram compresses on upload, so starting with exact target dimensions reduces quality loss.

Stories, Reels, and Full-Screen Ads

Instagram Stories, Explore ads, and Reels cover the full mobile screen. The ideal size is 1080 × 1920 pixels at 9:16. Keep critical text and subjects within the central 90% to avoid being obscured by UI elements. For Reels, export video at 1080 × 1920 with a high bitrate and H.264 encoding for stability on varying connections.

Short-form video performs strongly in today’s feed. Matching technical specs reduces processing issues and preserves clarity. Frame rate, bitrate, and container choices affect playback on low-bandwidth networks.

Video TypeResolutionFrame RateSuggested Bitrate (Mbps)
Reels1080 × 192030 fps8–12
IGTV (Long Form)1080 × 192030 fps10–14
Landscape Feed Video1280 × 72030 fps6–8

File Format, Compression, and Export Settings

Choose formats that balance quality and file size. JPEG is ideal for photos, PNG for graphics with transparency, and H.264 for video. Avoid repeated recompression by exporting once at full quality before uploading. Maintain a local master file at or above the target dimensions, and use a lightweight export preset for web. For carousels, design each slide with consistent margins so cropped thumbnails remain legible.

  • Photos: JPEG at 85–92% quality
  • Graphics/text: PNG-24 if clarity is critical
  • Videos: H.264, AAC audio, 8–12 Mbps for 1080p
  • File size limit: 30 MB for photos, reasonable bitrate caps for video

Device, Retina, and Accessibility Considerations

Most users view Instagram on Retina and high-DPI screens. Supplying images at or above the target dimensions ensures crisp rendering. Add concise alt text to improve accessibility and context in feeds. Maintain safe zones for key visuals, and test posts on mobile data and Wi-Fi to confirm quick loading. When in doubt, slightly larger files are downscaled gracefully, while upscaling smaller files often introduces softness.

Quick Checklist Before You Upload

  • Confirm aspect ratio matches the intended placement (1:1, 4:5, 9:16, 16:9)
  • Export at the target pixel dimensions with minimal compression
  • Use sRGB color profile for consistent on-device rendering
  • Verify legibility of text within central 90% for Stories and Reels
  • Run a mobile data check to ensure reasonable load times
