General cropping and preview warnings

Common pitfalls across most social platforms.

  • The feed thumbnail crop is rarely the upload crop. Most platforms re-crop to a different ratio for grid view, list view, or mobile lock-screen preview. Keep the focal element centered.
  • JPEG compression is aggressive. Heavy gradients and red text often show banding after upload. Export at 100% quality and let the platform re-compress.
  • Aspect ratio is enforced; pixel count is suggestion. Going above the recommended pixel size usually triggers down-scale; going below triggers up-scale. Match the ratio first.
  • Some platforms reject very small images. OG below 600 x 315, YouTube thumbnail below 640 x 360, IG profile picture below 320 x 320 — all silent rejections.
  • Always test on the actual platform before scaling. Use the platform's own preview / debug tool: Facebook Sharing Debugger, X Card Validator, LinkedIn Post Inspector.

Source and calculation method

Where social platform sizes come from and how SizeKit verifies them.

Source type
Mixed: official + practical
YouTube thumbnail and Open Graph are documented officially. Instagram, TikTok, X, and most others are practical working sizes based on the platforms' published guidance plus observed re-compression behavior.
Calculation method
Pick highest-fidelity ratio
For each surface, SizeKit picks the highest fidelity export that the platform does not down-scale. Where the official spec only states a ratio, SizeKit picks the 1080 px short side as the practical default.
Last reviewed
2026-05-29
SizeKit re-verifies social sizes every quarter. Major platforms typically change feed-default ratios about once a year. Some Chinese platform pages are flagged as needs-verification on their individual pages.
