      You can set another value for browser -> default_zoom_level in the file Preferences. Close Opera and backup the file before changing it. The new value will become available as one of the zoom levels, for example, when zooming, you go 100% - 125% - 127% - 150% ...

        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.

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