Wagner VI is a pseudocylindrical whole Earth map projection.
Like the Robinson projection, it is a compromise projection, not having any special attributes other than a pleasing, low distortion appearance.
Wagner VI is equivalent to the Kavrayskiy VII horizontally elongated by a factor of
This elongation results in proper preservation of shapes near the equator but slightly more distortion overall.
The aspect ratio of this projection is 2:1, as formed by the ratio of the equator to the central meridian.
This matches the ratio of Earth’s equator to any meridian.
