Sorry! All I know, since I only shoot RAW, is the raw file weight, which you already have.
If you want to make the tests yourself, here is what you can do: Setup your camera so it will be fixed and taking a same subject in the same light. Set the camera so it will record in raw, shoot. On the same card, Set the camera so it will record in jpg L, M, S, and one other shot for all the other available options, even tiff's. Be sure to note what is what, and one at your com- puter, transfer your files and images.
Voilà! In one single window you will have all the files and images with their respective weight and size…

The size of the files depends on: - the number of pixels - amount of data compression used - the amount of detail in your image (more detail = bigger size)
Take a few shots with your normal settings and you should get a reasonable idea of the file sizes.
If you are wondering about the "number of images left on the card" Nikon displays, the number is always noticeably lower than reality, on purpose.

Sorry it took so long to get back to you....it's been a crazy week for me.
It's nothing more than a curiosity for me regarding "average" file sizes for S, M or L JPG files for the D600. I have a D300, and was interested in file sizes going from a DX sensor to an FX sensor with twice the pixels.
