Paul, I don't know which editing program you are using, but here is an example. I created a new document in PCC entering the pixel dimensions you listed with a resolution of 300. The screen shot below confirms the dimensions. Towards the right side of the pop up box, you can see the word
Pixels with a drop down arrow next to it.

I clicked the drop down arrow and chose Inches (which automatically converts the measurement from pixels to inches).

So the starting size of your photo is slightly larger than 16"x9". You want to make sure the resolution is 300 if the image is going to be printed. Then hopefully whatever program you have has the ability to crop to a specific size (or ratio). If I wanted to crop this to 5"x7", I have the option to select those exact measurements OR I can select a 5x7 ratio. If I choose the latter, my overall file size is larger. Here is the same file now cropped to a 5x7 ratio. It is now a little larger than 9"x13" and could be printed as a 5x7 photo if desired.

What program(s) do you have, and what size are you looking to print?
