Direction needed

A friend of mine has a computer loaded with M$ Windows. She would like to try Linux but does not know how much room to make on the disk by partitioning (and whether SuSE will do the job for her or whether she should use Partition Magic). Where is there a guide that I can give her that will answer her questions? -- Best regards, Dennis J.
