How it works
A4 at 300 DPI is 2480×3508 px — required for sharp print, not for screen-only use.
Web banners near 1920×600 px fit common desktop headers; verify your theme’s exact slot.
Frequently asked questions
Why is the A4 file so large?+
300 DPI print needs many pixels. For screen PDFs or previews, use a smaller width (e.g. 1240 px) instead.
