Photoshop zoom settings

Question

Before I formatted my Mac, I'm sure I had Ps set up so that, when I zoomed, it didn't change the size of the window that my document was in.

Now when I zoom in, or zoom out, the window will resize automatically along with it

I'm sure there was a setting to change this in preferences, but have no idea where it is?

Answer 1

This is indeed a setting in the preferences:

1. Go to Photoshop > Preferences (Cmd+K; Edit > Preferences and Ctrl+K for Windows);
2. In the General tab, untick 'Zoom Resizes Windows';
3. Click OK.
