Social Media Image Sizes (2026)

The recommended feed post size is 1080 × 1350 pixels (4:5 portrait) — it takes up the most screen space. Square posts are 1080 × 1080 (1:1) and landscape is 1080 × 566 (1.91:1). Stories and Reels are 1080 × 1920 (9:16).

1080 × 1920 pixels at a 9:16 aspect ratio. Keep text and stickers inside the central safe zone (roughly 1080 × 1420), because the top and bottom are covered by the camera, username, and reply UI.

TikTok is 9:16 vertical — upload at 1080 × 1920 pixels. Other ratios play but get letterboxed with bars, which hurts watch time. Export at a high bitrate since TikTok compresses aggressively.

1280 × 720 pixels (16:9), under 2 MB, as JPG, PNG, or GIF. Design text large enough to read when the thumbnail is shrunk to about 10% — that's how most viewers see it in search and suggested feeds.

Upload 2560 × 1440 pixels, but keep all text and logos inside the central 1546 × 423 pixel safe area — that's the only region visible on every device from phone to TV.

820 × 312 pixels on desktop, but mobile crops it to roughly 640 × 360 — keep important content centered so both crops work.

Platforms crop or letterbox mismatched media automatically: faces get cut, text gets cropped, and vertical feeds show black bars around landscape video. Correctly sized media fills the screen, looks intentional, and gets measurably better watch time and engagement.
