For some reason the official PDFs offered by Wizards weren't letter sized, and the character sheet contained crop marks. I cropped the character sheet to 8.5x11 inches and resized the logsheet to 8.5x11 inches.
Further reductions when printing might be necessary depending on your printer's borders. This is usually automatic when printing from Adobe Reader on Windows and OS X or Preview on OS X.
Enjoy!
