Pixel size of Nes levels/characters?

I've looked on the Internet for Samus pixel size and the sizes of each "block" that builds the levels. I've found each room to be 256x240 pixels, 32x30 pixels, and broken down each block 4x4 or 8x8. Not sure which is correct or if it is something else. Samus was 16x48 or maybe I'm off. Anyone know the exact?

Thanks.

Oops, Samus from Metroid.

NES graphics were done with tiles like you say, but most games made use of larger sprites by combining multiple tiles together. You could look for an nes emulator with a debug view to look at it I guess.

If you want to really get into the meat of NES restrictions then these threads contain a lot of good info:
