"Each Ethereum block has a maximum size, which limits the amount of data that can be included. The current maximum block size is set at 12.5M gas and was last increased in July 2020. Since the maximum block size is denominated in gas and different transactions have different gas usages based on complexity, there isn’t a consistent maximum number of transactions that can be included in a block. But on average, about 160-200 transactions are included per block."
