About this tool
Pick a platform and a placement to see the commonly used pixel dimensions and aspect ratio for that slot. This is a reference table, not a live spec feed: platforms change their specs, so verify the size in the platform's own guide before publishing.
Frequently asked questions
Are these sizes guaranteed current?
No. Platforms update specs without notice, so treat this as a reference and verify before publishing.
What if my image is larger?
Larger images at the same aspect ratio usually scale down fine; the ratio matters more than exact pixels.
