Questions creators ask
Practical notes for a faster, more confident pre-publish check.
How current are these sizes?
Each row includes a status and last-reviewed date. Platform requirements can change, so confirm them before a paid campaign.
Can I copy a dimension?
Yes. The copy control places the width × height value on your clipboard.
Do sizes include interface safety?
Pixel dimensions describe the canvas. Use the linked checker to consider likely interface obstruction.
