Why this keeps changing

Platforms change placements, responsive layouts, upload rules, and recommendation pages. They may also test different interfaces for different accounts. Record the source and verification date for each preset, and check again before a launch, paid campaign, profile redesign, or template rollout.

These values are presets, not promises about every crop or device. Distinguish a platform's minimum upload requirements, recommended dimensions, supported aspect-ratio range, and visible safe area. If no official value exists for a placement, label the preset as a practical convention rather than presenting it as a platform specification. Preview the actual placement instead of assuming a supported ratio will always display uncropped.

Last verified: August 2026. Cite an official source beside every platform represented in the table; Facebook, YouTube, and X sources alone do not validate Instagram or LinkedIn presets. Recheck the relevant placement before an important upload.

The "safe area" trap on banners

Banner visibility changes with viewport, device, account controls, and interface overlays. Keep logos, text, faces, and calls to action inside the platform's currently documented safe area, but also preview desktop and mobile views. A safe-area diagram is a planning aid, not proof that every interface will leave that region unobstructed.

Square vs portrait vs landscape: pick based on where it lives

Different placements often need different compositions, not merely resized copies. A landscape thumbnail and a vertical story emphasize different areas of the frame. Create purpose-built crops from a master image, keep important content away from interface overlays, and review automated crops before publishing.

How to hit these sizes without guessing

A preset can enforce the recorded pixel dimensions and aspect ratio, but it cannot know whether the platform has changed or where each interface will place overlays. Treat presets as versioned starting points. Verify the source date, position the subject deliberately, and inspect the exported pixels.

Planning ahead for a batch of posts

If you're preparing several images at once (a week's worth of posts, a campaign launch, a rebrand across profiles), it's faster to crop everything to spec before you start scheduling than to fix rejected or awkwardly-cropped uploads one at a time afterward. Build a habit of checking the target size for each placement first, then crop directly to that size, rather than uploading a single one-size-fits-all image and hoping each platform handles it gracefully. It rarely does.

Checks before publishing

What happens with another size? The service may accept, crop, pad, rescale, recompress, generate several derivatives, or reject it. Behavior depends on the placement and can change.

Do dimensions affect quality? Yes, but so do source quality, compression, color space, file format, text size, and platform recompression. Uploading the recommended dimensions does not guarantee a pixel-identical display.

When should presets be checked? Before major campaigns and on a regular maintenance schedule. Store a verification date and official source with each preset so stale values are visible.

Crop for any social platform instantly

Orisod's social media cropper includes versioned presets for common placements. Confirm that the selected preset still matches current official guidance and preview the result on the platform.

Dimensions are one part of a reliable social asset. Composition, safe areas, legibility, source traceability, and a real placement preview matter just as much.
