Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a plurality of carriers in a cross-carrier scheduling scenario, whether a quantity of downlink control information (DCI) sizes for a set of DCIs that the UE monitors satisfies a threshold, wherein the threshold is a per scheduling cell per scheduled cell threshold or a per scheduled cell threshold. The UE may selectively perform a DCI size alignment procedure to adjust a DCI size configuration based at least in part on whether the quantity of DCI sizes satisfies the threshold. The UE may monitor for the set of DCIs based at least in part on the DCI size configuration. Numerous other aspects are provided.
