Windows 7: How much space is needed to make an image on an external hard drive

How much space is needed to make an image on an external hard drive

This is probably a real basic question. I want to make an image of my hard drive using Macrium Free. The MBR is 100 MB and the primary drive is 471 GB. Do I need at least 471.1 GB of free space on the external drive for the image or does the imaging software compress the size so that a lesser amount of space is needed?

It will apx. 60% of the SPACE USED, not the total size of the partition.

i.e. If you USE 100 GB of the 471 GB, the image will be apx. 60 GB
