The pages are printing out too small/they don’t fill the paper I’m using.

My PDF products are designed to print on standard US Letter paper (8.5” x 11”) but they should also print well on A4 paper. The images and text should fill the page, 1/4” white margin around all edges.

Check the settings in the Adobe Acrobat Reader print dialog box. Make sure you’ve selected “Actual Size” as the size option.
