Every social media image size you actually need in 2026

The four aspect ratios that cover 95% of social

Before the size tables, the ratios you'll actually use:

• 9:16 - vertical, mobile-first. TikTok, Reels, Shorts, Stories.
• 1:1 - square. Instagram feed's oldest ratio, still widely posted.
• 4:5 - portrait. Instagram feed's most-used ratio now (more screen real estate than 1:1).
• 16:9 - landscape. YouTube videos, X cards, LinkedIn shares, blog headers.

Two lesser but common:

• 1.91:1 - X card, LinkedIn share, Facebook link preview (~1200×628).
• 21:9 - ultrawide cinematic. Used for scroll-stopping YouTube thumbnails and hero images.

Aspect Ratio Calculator covers all of these plus a bunch more with one-click presets.

Instagram (2026)

• Feed square - 1080 × 1080 (1:1)
• Feed portrait - 1080 × 1350 (4:5) - the current default; gets the most feed height.
• Feed landscape - 1080 × 566 (1.91:1) - rarely used; loses feed real estate.
• Story / Reel - 1080 × 1920 (9:16)
• Profile picture - 320 × 320 minimum (displayed circular).

TikTok

• Video - 1080 × 1920 (9:16). TikTok compresses aggressively - start with the highest quality your camera produces.
• Profile picture - 200 × 200 minimum.

YouTube

• Video - 1920 × 1080 (16:9) for standard, 1080 × 1920 (9:16) for Shorts.
• Thumbnail - 1280 × 720 (16:9). Under 2MB. JPG or PNG.
• Channel banner - 2560 × 1440. Safe area for logo: 1546 × 423 center.
• Profile picture - 800 × 800.

Grabbing an existing thumbnail: YouTube Thumbnail Downloader pulls every resolution YouTube stores (default, medium, high, standard, maxres).

X (Twitter)

• Post image, single - 1600 × 900 (16:9) - displays at 1200×675 in feed.
• Post image, 2-image layout - 700 × 800 each (side-by-side).
• Post image, 3+ layout - 1200 × 686 each.
• Video - up to 1920 × 1200. 16:9 or 1:1 are the safe defaults.
• Header - 1500 × 500.
• Profile picture - 400 × 400.

LinkedIn

• Personal post image - 1200 × 627 (1.91:1) for shared links; 1200 × 1200 for square feed images.
• Company page cover - 1128 × 191.
• Personal profile background - 1584 × 396.
• Article header - 1200 × 627.
• Profile picture - 400 × 400.

Facebook

• Post image - 1200 × 630 (1.91:1) - same as an OG image.
• Cover photo - 820 × 312 desktop, 640 × 360 mobile. Design the safe area accordingly.
• Story - 1080 × 1920.
• Profile picture - 320 × 320.

Pinterest

• Pin image - 1000 × 1500 (2:3). Vertical pins massively outperform square or landscape.
• Board cover - 217 × 147.
• Profile picture - 165 × 165.

Discord

• Server icon - 512 × 512.
• Server banner - 960 × 540 minimum.
• Emoji - 128 × 128 (uploaded); displayed at 32×32 or 22×22.
• Profile banner (Nitro) - 600 × 240.

The OG image (used by Facebook, LinkedIn, iMessage, Slack, Discord)

• 1200 × 630 - the safest single OG image size. Every social platform that renders link previews uses this ratio.

The workflow

Two tools handle everything above:

• Image Resizer - with one-click presets for the sizes above (Instagram square, IG story, YouTube thumbnail, X card, LinkedIn banner, Facebook cover).
• Aspect Ratio Calculator - when you know one dimension and need the other; also verifies the reduced ratio (spot the "why does this crop weird" bug).

After resizing, compress to keep uploads fast: Image Compressor at WebP quality 78 typically produces files 60% smaller than the JPG the resizer emitted, with no visible quality difference.

Video export sizes for the same platforms

Since aspect ratio calculators only handle dimensions and not codec: for video, MP4 (H.264 + AAC) is universal; WebM is fine everywhere except a few older cameras. Frame rate: 30fps unless you deliberately need 60 (gameplay, sports). Bitrate: YouTube and TikTok re-encode aggressively, so start high (10-20 Mbps for 1080p) and let their servers downsize.

Every size, one bookmark

The two most-reached-for tools for this workflow live at:

• Image Resizer
• Aspect Ratio Calculator

Bookmark both. When Instagram or TikTok changes a spec (they do, quietly, every few months), the presets in these tools stay current - and worst case, you enter the new number manually in one field and get the matching dimension in the other.
