For subsets in the standard symplectic space $(\mathbb {R}^{2n},\omega _0)$ whose closures are intersecting with coisotropic subspace $\mathbb {R}^{n,k}$
we construct relative versions of the Ekeland–Hofer capacities of the subsets with respect to $\mathbb {R}^{n,k}$
, establish representation formulas for such capacities of bounded convex domains intersecting with $\mathbb {R}^{n,k}$
. We also prove a product formula and a fact that the value of this capacity on a hypersurface $\mathcal {S}$
of restricted contact type containing the origin is equal to the action of a generalized leafwise chord on $\mathcal {S}$
