Policing is typically done on the L2 packet size - that is, the size on the wire, excluding the Preamble, Start Frame Delimiter (SFD), and Interpacket Gap (IPG). To ensure that the policer polices the right amount of L2 packet size, a default packet size adjustment is configured, which is deducted from the size seen on wire.
