The Raspberry Pi Fedora Remix 14 is about 1.6GB, so it fits comfortably on a 2GB SD card with a few hundred MB available, though you may want a larger card to leave more room for extra programs or for data. There is a lot of software available for the Remix that isn't in the initial card image -- you can [[Raspberry_Pi_Fedora_Remix_Administration#Updating.2C_Adding.2C_and_Removing_Software|add and remove]] software to get exactly the combination you want. The compressed image is a little under 600 MB - about the size of a CD.
