Can we produce a true size map that can also be used as a navigation map? (lemmy.world)

Total commoner here that does not understand projection and such on maps, but I know that the popular map and commercial globe somehow does not show the true size of a country/area.

My first question is, how could a globe (which supposed to be a representation of earth from space) does not represent true size of an area?

Second one, can we produce a map that shows the true size of an area but can also be used for navigation?

I might have used wrong term here, what i mean is that if you go to thetruesize.com which claims to be showing the real size of the area/country, you can see that australia for example will be almost as big as russia, but its not the case in a globe. I wonder if i misunderstand these wrongly

TheTrueSize.com still uses Mercator projection. You need to drag Australia and Russia to the equator to see their true size. The map around equator has the minimum amount of distortion. Also on a globe if you put a tape measure against those two countries you’d see that Australia is about as tall as Russia
