Maximum standard Ethernet frame
A standard untagged Ethernet frame is at most 1,518 bytes from destination address through frame check sequence. Preamble, start delimiter and interpacket gap are excluded; VLAN tags and jumbo frames use other sizes.

Why we use 1.518 kB
For comparison, this page uses frame size including fcs. The record labels this value standard, so the stated convention rather than an inferred average controls the comparison.
