      That sounds just what I need. Where will I find the 'Preferences' file to edit?

        It's on Opera's profile folder. Check Menu > About Opera for the path.

          Thank you both.

          My browser settings default zoom level is set to 175%. In preferences that is shown as "default_zoom_level": 3.069389038663465 How do I decipher it?

              Or, as I see in the source code, zoom_level = log(zoom_factor, 1.2), where the logarithm base 1.2 is a constant.

                  Could a mathematician here tell me the figure for 180% and 185% please?

                    Don't have a calculator handy, but it is log(x)/log(1.2), in your case x would be 1.8 or 1.85 ...

                      Hey that's great. Thank you. I just substituted for x and put it into Google and it gave me the figure! 🙂 I never knew Google could do that.

                      3.37417938892

                      Now to see if it will do the business in Prefs.
