contents We study definable ranks of ordered fields, ordered abelian groups, and linear orders. For an arbitrary linear order $Γ$, we construct an ordered abelian group $G$ with archimedian spine $Γ$ and an ordered field $K$ with natural value group $G$ such that the definable ranks of $K$, $G$ and $Γ$ are all isomorphic. This answers a question of Krapp, Kuhlmann, and the second author.
