Social Media Image Sizes for 2026 (Every Major Platform)

Instagram: square, portrait and stories

Instagram serves feed images at a maximum width of 1080 pixels, so that's the width to supply. Square posts are 1080x1080; 4:5 portrait posts at 1080x1350 take up more vertical space and tend to stop the scroll better. Stories and Reels are full-screen vertical at 1080x1920 (9:16) — keep key content in the middle 80% so the interface doesn't cover it.

• Square post: 1080×1080 (1:1).
• Portrait post: 1080×1350 (4:5).
• Story / Reel / cover: 1080×1920 (9:16).

Facebook: the 1.91:1 link banner

For shared images and link previews, Facebook wants 1200x630 — a wide 1.91:1 banner, which is also the Open Graph size it reads from web pages. Supply that and a shared link shows a large, clean image; supply the wrong shape and it's cropped to a strip or shrunk to a thumbnail beside the text.

• Shared image / link preview: 1200×630 (1.91:1).

X (Twitter): 16:9 in the timeline

X previews a single inline image at a 16:9 ratio, so 1600x900 fills the timeline without being cropped. The full image still appears when tapped, but a tall infographic can look broken in the feed — for those, crop the most important part to 16:9, or accept that users must expand it.

• Single post image: 1600×900 (16:9).

LinkedIn: professional polish at 1200x627

LinkedIn recommends 1200x627 for shared images and link previews — a 1.91:1 banner all but identical to the Open Graph standard, so one export tends to cover LinkedIn, Facebook and most other networks. In a professional feed, a cropped logo or beheaded headshot reads as sloppy, so decide the crop deliberately.

• Shared image / link preview: 1200×627 (1.91:1).

The golden rule: crop, then resize

Most source images don't match these shapes, so the order matters. Crop to the target aspect ratio first — keeping faces, logos and text safely inside the frame — and only then resize to the exact pixel dimensions. Doing it the other way round lets the platform centre-crop for you, which is how important parts get lost.

Matching sizes across a multi-image post or a campaign also pays off: consistent dimensions stop networks from cropping unpredictably and keep carousels and sequences lined up.

A private, browser-based workflow

Each of these sizes has a dedicated preset on PixelResize, and all of them run entirely in your browser — nothing is uploaded, so unpublished campaign visuals stay on your device.
