Facebook image sizes
Event covers cropped for both the desktop banner and the phone card, from one upload.
Only one Facebook asset is built here, deliberately. The generic Facebook size queries are dominated by long-established high-authority pages, and adding another thin size chart to that pile helps nobody.
Event covers are different: a real, specific job with two crops to satisfy, and a genuine gap in working tools. That is the page below. Other Facebook assets are recorded in the project backlog rather than shipped as placeholders.

Facebook questions
What size is a Facebook event cover photo?
1200 × 628 pixels, roughly 1.91:1, which is Meta’s recommended minimum quality target for images at this placement.
Why are there no Facebook page or post size tools here?
Honesty about where this site adds value. Those queries are saturated by established pages and the tool would be identical to the ones already built. They are listed in the backlog with that reasoning rather than published as filler.
Doing more than one platform?
The One Image to Social Pack applies a single focal point across every destination you pick and gives you one ZIP with a manifest listing each size, its source and the date it was checked.
