Editorial Policy and Source Standards
ImageSizeKit publishes image size guides and local browser tools for creators. This policy explains how we choose sources, handle corrections, and separate official requirements from practical workflow advice.
Editorial principles
Official source first
When a platform provides a public help page or upload requirement, that source gets priority.
Task before keyword
Pages are written around a creator task such as checking a thumbnail, planning a banner, or avoiding crops.
Local privacy by default
Upload checkers should read dimensions and file metadata in the browser whenever possible.
Clear update dates
Pages that depend on platform requirements should show a last-checked date near the relevant guidance.
How pages are reviewed
| Step | Standard |
|---|---|
| Collect sources | Start with official platform help pages, visible product behavior, and clearly dated public documentation. |
| Compare creator workflows | Use community questions and SERP patterns as user-language evidence, not as official specifications. |
| Update the page | Revise direct answer blocks, specs tables, FAQ, schema, and related links when the change affects users. |
| Record the boundary | If something is uncertain, say so and point users back to the official platform before publishing assets. |
Corrections
If you find an outdated size, broken tool behavior, unclear wording, or a source that changed, contact us at hello@imagesizekit.com. Include the ImageSizeKit URL, the source URL, and the date you checked the source.
Current focus
The current editorial focus is YouTube creator image assets: thumbnail size, banner size, banner safe area, thumbnail text readability, blurry upload troubleshooting, and 16:9 export math. Start from the YouTube image sizes hub.
