The action dimension of a discrete group Γ is the smallest dimension of a contractible manifold that admits a proper action of Γ . Associated to any flag complex L there is a right‐angled Artin group, AL . We compute the action dimension of AL for many L . Our calculations come close to confirming the conjecture that if an ℓ2 ‐Betti number of AL in degree l is nonzero, then the action dimension of AL is ⩾2l .
