@elliemp Are you playing at a resolution of 2560x1600? If not, that's the first thing to try: changing the in-game resolution to match your screen.
If that doesn't help, try changing the user and system DPI settings to 96 (100%) rather than the 144 it's using now. You should be able to use the higher DPI setting, but it's an easy test to see whether this is in fact the issue. This guide is helpful, but you only need option one:

If that works but you'd like to keep the higher DPI scaling, let me know.
