Image & video sizes

The correct pixel dimensions for every major platform, with a resizer on each page.

The sizes most people need first

  • 1080 × 1080 — Instagram square post (1:1), the safe default for the feed.
  • 1080 × 1920 — vertical for Stories, Reels, and TikTok (9:16).
  • 1280 × 720 — YouTube thumbnail (16:9); keep it under 2 MB.
  • 1200 × 630 — link-preview / Open Graph image for Facebook and LinkedIn (1.91:1).

Set these four and you're covered for most posting; use the full list below for everything else.
