Screen Resolution on 7548 - Inspiron 15 7000

I've noticed that anytime I take a screenshot with the Windows Snipping Tool (or any other tool, for that matter) and paste into Word doc, Excel sheet, or Outlook Email, the screenshot pastes as a size that is huge. I have to resize everytime. It's extremely frustrating to have to do this every time. Is there a fix for this? How can I prevent this happening?
