I need some clarity

Bruce nailed it. More pixels is not the answer. That's a just a way companies, trick you into buying new cameras. It has 50 megapixels, so what. They are small. Bigger is better when it comes to mega pixels. Google, it if more is better, find out for yourself.
They are other questions, are you using a tripod? How good is your lens and lastly how far away are you?

I beg to differd:
larger pixels are better with lower light
smaller pixels show more detail (sharper) when you have good light
But, up to a certain size enlargement or a certain degree of cropping it makes little difference to the viewer. Pixel Peepers excluded, if you had a million pixels per mm properly exposed with good light they would keep enlarging the image until it wasn't sharp anymore then complain about your focus. Never mind that at the enlargement setting they used a projected image or print would be so big you would have to stand on the next block to view the whole thing.

I was told very politely in a PM right after I first started with UHH that it was not polite to post photos or links to photos in someone else's thread and if I wanted to do that to open a new thread. If that is not so then at least two of us are mistaken. I apologize for breaking another rule that I did not know existed. Is there a list of these rules I can read so I don't transgress in the future?

What ISO are you using? The higher (faster) the more grain you will have, especially when you enlarge it. You might want to try a program like InPixio Photo Maximizer 4. It is not expensive and actually does work very well. Use a despeckle filter or some other type of noise reduction algorithm. Do not over sharpen.

If you zoom in past the number of pixels to print a sharp picture, then yes, it will be fuzzy.
BUT, any picture looks sharper at low resolution than at high resolution. I periodically photograph art for a local non-profit. I focus. It looks great, then I look at the image through live view (Nikon's name for the screen) and use the zoom button to the max (NOT zooming the lens, just zooming the image) and it's always out of focus. So then I carefully focus as best I can. The resulting image can be cropped and blown up very successfully. Of course there's a limit, but it's much sharper than it would have been otherwise.

To the OP. When you blowup an image you loose resolution and when you shrink you gain resolution. If you are outputting as a tiff or jpeg you will get jaggies when blowing up. Open in photoshop and save as an eps and output. EPS keeps its resolution.
I am a print designer and been doing this for far to long.

There was an image posted online. I think it was an ad by
Bentley. It was a distant shot of the Golden Gate Bridge.
As you zoomed in to the Bentley driving on the bridge, it
was still sharp. I found it. Zoom all the way in, and you
will see the "B" on the seatback - razor sharp.

Won't click the link cuz car adverts bring excessive
junk mail and a tsunami of targeted pop ups. BDDD.
However, it's verrrry likely you're NOT zooming in to
find incredible detail within one SINGLE hi-rez frame.
Sophisticated ads use a VR method, combining many
frames of wide, mid, and closer shots, but acoarst it
only displays one at a time. It's like zooming in from
a Google Earth high altitude view and then you wind
up strolling in a virtual street level neighborhood.
If you wanna see extreeeeemely impressive versions
of this that are CRAZY FUN to zoom around in, do a
google for "360 Cities".

Sorry but grain is not noise. The higher the ISO the more Noise you will get in your shot. Grain is only in film and old silver images. Sorry but as photographers we need to keep from confusing all the newbies that show up. Good way to get rid of some noise though. There is also a noise filter that has adjustments to eliminate or even add noise in Adobe. Using noise (by adding noise) in a photo we can also simulate rain.

Clever PP- the bridge is a photo, the Bentley is a vector graphic embedded into the jpg. It will always be sharp no matter how much the zoom is.
Aha! Your comment is the first time I read something about vector graphics that explains what the fuss is all about. Now I need to look into it, having some motivation. Thanks!
Geez, you can even see the stitching of the logo.
