Superconformal field theories (SCFTs) in two, four, and six dimensions have "Weyl anomalies"---i.e. anomalies under Weyl scalings---that are characterized by their so-called "central charges". I explain how these central charges can be produced holographically through computations in the dual AdS supergravity theories. In particular, I present simple formulas---discovered in collaboration with Larsen, Liu, and Szepietowski---relating the subleading central charges of 2d and 4d SCFTs to the superconformal index of their dual supergravity theories. The formulas confirm many well-understood dualities, and lead to novel predictions for several still not-well-understood holographic SCFTs. Finally, I describe the ongoing work on the analogous problem for 6d holographic SCFTs.
