• Heinz means constant
• absolute normalized norm
• convex function

In this paper, we calculate the precise values of the Heinz means constant under the absolute normalized norms in R2. The conclusions do not only contain some previous results, but also give the exact values of the Heinz means constant for some new concrete Banach spaces.
