Here you can see interactive overviews for each scale (1.16.5 survival with features). You can zoom in and out and find the coordinates by hovering with the mouse over a region.
When completely zoomed in (the standard zoom level), 1 pixel on your monitor represents 1 block ingame. All maps where generated with uNmINeD.
You are looking for overviews of the legacy maps? Check out this post.
