2026 Social Media Image Size Guide: The Ultimate Cheat Sheet
In 2026, social media platforms have reached a "Retina-standard" baseline. Low-resolution images are no longer just an aesthetic issue—they are a ranking factor. Platforms like Instagram and LinkedIn now use visual clarity as a signal for content quality. If your images are blurry, your reach suffers.
The "Device-First" Optimization Strategy
With 94% of social media consumption happening on mobile devices with high pixel density (3x to 4x), uploading "exact" sizes often leads to blurriness. In 2026, we recommend the 2x Rule: Always upload assets at twice the required display size to ensure they remain sharp on OLED and ProMotion displays.
1. Instagram Dimensions (2026)
Instagram remains a portrait-first platform. To maximize engagement, your content should occupy the maximum vertical space available in the feed.
- Profile Photo: 320 x 320 px (appears as a circle)
- Square Post: 1080 x 1080 px (1:1 aspect ratio)
- Portrait Post: 1080 x 1350 px (4:5 aspect ratio - Recommended)
- Stories & Reels: 1080 x 1920 px (9:16 aspect ratio)
- Reels Cover: 1080 x 1920 px (ensure text is in the central 1:1 area)
2. LinkedIn Professional Sizes
LinkedIn banners are notoriously difficult to optimize due to their extreme aspect ratio. Using a PNG-24 format here is essential to avoid the heavy artifacts LinkedIn applies to JPGs.
- Profile Image: 400 x 400 px
- Personal Cover Photo: 1584 x 396 px
- Company Logo: 300 x 300 px
- Company Page Cover: 1128 x 191 px
- Post Image: 1200 x 627 px
3. Facebook Branding Assets
Facebook's compression engine is aggressive. For cover photos containing text or logos, we highly recommend using the PNG format through our converter to bypass initial blurriness.
- Profile Picture: 176 x 176 px (Desktop) | 196 x 196 px (Mobile)
- Cover Photo: 820 x 312 px
- Event Cover Photo: 1200 x 628 px
- Shared Link Thumbnail: 1200 x 630 px

Batch Resize NowTechnical Tip: The "Safe Zone" for Stories
When designing for Stories or Reels (1080 x 1920), keep all essential text and logos within the central 1080 x 1420 px area. This prevents your content from being covered by the profile avatar at the top or the CTA buttons at the bottom.
