I usually buy fat quarters. But if it's a fabric I cannot live without, I buy one yard/meter. If it's perfect for a border, 2 yards/meters, and if it's the right quality for backing, 5 to 8 yards/meters. I do confess to be a fabricaholic!!
This is my answer too - FQs feed my scrappy heart but then you need borders and backing to complete the quilt usually.
