Hi Stacey!
We will add support for entering inches in a future update. For now, here are the dimensions you requested:
7.75″ x 10.25″ = 2325 x 3075
7.75″ x 5″ = 2325 x 1500
By the way, the way to calculate this is simply multiple the inches by 300. So 7.75 x 300 = 2325. This is the calculation for 300DPI which is the standard print quality for most printers.
