How to use the Social Media Image Sizes
Each platform has its own image dimension requirements that change frequently. The reference covers profile photos, cover images, post images, story formats, and ad sizes for every major platform.
Pick the platform
Facebook, Instagram, X (Twitter), LinkedIn, Pinterest, YouTube, TikTok, Snapchat, Threads.
Pick the asset type
Profile picture, cover photo, post image, story, reel cover, ad, link preview.
Read the spec
Each spec includes pixel dimensions, aspect ratio, recommended format (PNG vs JPG), maximum file size, and safe zone (areas not cropped on different devices).
Design and export
Build the asset to spec. Export at 2× resolution for retina displays. Save the file under the platform's max size.
Why image dimensions matter on social
Wrong-sized images get auto-cropped, pixelated, or letterboxed — all of which hurt engagement. Right-sized images render cleanly across desktop, mobile, and apps. The dimension differences across platforms are surprisingly large; one image rarely works everywhere.
The universal sizes worth memorizing
- 1200 × 630 (1.91:1) — Open Graph, Twitter card, LinkedIn share, most preview cards.
- 1080 × 1080 (1:1) — Instagram feed post, Facebook square post.
- 1080 × 1350 (4:5) — Instagram portrait post, Pinterest pin.
- 1080 × 1920 (9:16) — Instagram/Facebook/TikTok story, reel, YouTube short.
- 1500 × 500 (3:1) — X (Twitter) header.
- 1200 × 627 (1.91:1) — LinkedIn post and share preview.
- 2560 × 1440 (16:9) — YouTube channel art / banner.
Why these specs change
Platforms tweak their feed layouts and crop ratios every 6–12 months. The most common changes: a platform adding a new placement (Instagram added Reels, then story-style ads, then Threads) or shifting the dominant aspect ratio (Instagram went from square to portrait around 2020). The reference is updated when these changes ship.
Safe zones
Different devices crop the same image differently — a Facebook cover photo shows differently on desktop vs mobile. The "safe zone" is the central area that's always visible. Place critical content (logos, faces, CTAs) inside the safe zone. Decorative elements can extend to the edges where they may get cropped on some devices.
Frequently asked questions
What's the most universal image size for social media?
1200 × 630 pixels at 1.91:1 ratio. This works as og:image (Facebook/LinkedIn/Slack/Discord), twitter:image (X), and most link-preview cards. If you can only create one image, this is the one. For native posts on individual platforms, use platform-specific sizes (1080 × 1080 for Instagram feed, 1080 × 1920 for stories).
Should I export images at 2× for retina displays?
Yes when possible. Most social platforms display at 1× but downscale 2× images cleanly, while upscaling 1× images on retina displays produces visible blur. The trade-off is file size — 2× images are 4× the file size. Stay under each platform's maximum (typically 5–10 MB).
What aspect ratio works for Instagram?
Three native ratios: 1:1 (square, classic feed), 4:5 (portrait, takes up more feed space), and 9:16 (full-screen for stories and reels). 4:5 portrait posts get higher engagement than square because they occupy more screen real estate. Reels and stories require 9:16 vertical.
Why does my image look blurry on Twitter / X?
Three common causes: (1) image is below 1200 × 630, X upscales and softens; (2) image was uploaded as a JPG with high compression — try PNG; (3) image was resized after upload — always upload at native resolution. Images at exactly 1200 × 630 in PNG format consistently look sharp.
How often do social media image sizes change?
Major platforms tweak specs every 6–12 months. Recent changes: Instagram shifted toward 4:5 portrait (2020), TikTok normalized 9:16 vertical-first content (2021), LinkedIn redesigned link previews (2023), Threads launched with Instagram-derived specs (2023). Keep references updated annually.
