Google map scale

It always frustrate me to find maps don't come with scale. It is particular important if you try to judge whether a route is within walking distance. Google map is an incredible tool. But it needs to show the scale too!

So I have decided to make my measurements and come up with some reasonable estimate. I will use the zoom control as the scale. Up to 9 zoom levels were measured with level 1 being the most detail. The distance between the center of + mark and the - mark, is shown below. Beware that the projected images near the poles (e.g. Helsinki,Finland) seems significantly distorted.
