Trying to cut a specific size out of an image

Question

Hello, I don't use photoshop very often so usually I end up asking somewhere like here when I need to do something specific.
I need to cut a section out of an image in a predetermined aspect ratio e.g. I want to be able to zoom into the image at any level then use some kind of tool to hover a box which is the right ratio over the area I want and basically copy it into a new document. The idea being I can then resize the new image based on size e.g. width 250px while keeping the aspect ratio, I want to do this with many pictures in order to get a consistent look on the page. I can't see any obvious way of doing this, any ideas/
thanks

Select the Rectangular Marquee tool; in the Options bar at the top, under Style select Fixed Ratio, and put in the ratio values.
You can now make a selection in the image and, holding Ctrl and Alt keys, drag the selection into the new document.
