Do RAW images take up more room on a memory card than Normal images?

I don't know if it matters, but I'm using a Nikon D3100.

Added (1). On my camera the quality options are Basic, Norm, Fine, RAW, and RAW + F

Then of course theirs large, medium and small, mines always been at large.

So if I use RAW, does that take up more room on my memory card than Norm?

RAW is typically a file type. The amount of space on a memory card that a picture uses depends not only on the file type being created, but also the quality of the picture - which is set on the camera itself.

An uncompressed RAW image is going to take up more than any other file type other than maybe a TIF file. Raw is basically a dump of the information that has been pulled from the camera sensor with no processing. The other type of image your camera can save is a JPG file, this is a lossy, compressed file and will always be smaller.

*Some RAW files can be compressed - but in a lossless manner. These files are smaller than an uncompressed RAW file, but still larger (usually) than a JPG file.

Everything else being equal (image size), a RAW file will take more space than a JPG.
