Every social platform has its own image-size requirements, and they change often — Instagram alone moved to a taller 3:4 profile grid in January 2026 and now favors 4:5 portrait feed posts. This guide gives you the current, correct dimensions for 2026 across Instagram, Facebook, TikTok, LinkedIn, X (Twitter), Pinterest, YouTube, Threads, and Snapchat — so your visuals never get cropped or blurred. Last updated: May 2026.

The single most useful rule in 2026: design feed posts at 1080 × 1350 px (4:5 portrait) and all vertical video (Reels, Stories, TikTok, Shorts) at 1080 × 1920 px (9:16). 1080 px wide is the universal baseline.

Quick reference: social media image sizes (2026)

1. Instagram image sizes (2026)

Instagram is the most format-sensitive platform. In January 2026 it switched the profile grid from square to a taller 3:4 portrait layout, and Meta now recommends 4:5 portrait feed posts because they take up more screen space and earn more reach. Square posts still upload, but they appear cropped on the new grid.

Recommended Instagram dimensions

• Profile picture: 320 × 320px (displays as a circle — keep your subject centered)
• Feed — portrait (recommended): 1080 × 1350px (4:5)
• Feed — square: 1080 × 1080px (1:1)
• Feed — landscape: 1080 × 566px (1.91:1)
• Stories & Reels: 1080 × 1920px (9:16) — keep text and logos within the center 1080 × 1420px area so the username bar and reply field don’t cover them
• Carousel: up to 20 images, all at the same aspect ratio (1080 × 1350 recommended)
