The size of a standard Ethernet frame is 1500 bytes.

The key idea is that the amount of user data inside a standard Ethernet frame is limited to 1500 bytes. This 1500-byte value is the maximum payload (the MTU) defined by the Ethernet standard. The frame itself includes a header and a trailer: a 14-byte header (destination and source MAC addresses plus EtherType or length) and a 4-byte FCS, so the total frame on the wire is typically 1518 bytes (and 1522 bytes if a VLAN tag is present). The payload size of 1500 bytes remains the same, while the extra bytes lift the total frame length. The other numbers don’t match this established payload limit, so they aren’t the standard payload size.
