    The smallest allowable Ethernet frame is 64 bytes.

    The question is what kind of Ethernet header is being used, one with or without 802.1Q tagging.  If we assume no tagging the preamble + frame header is 26 bytes, not counting inter frame gap (12 bytes).

    64 bytes - 26 bytes = 38 bytes of user data, roughly 60% of the frame contains user data.

    The meta data (headers and trailers) on an Ethernet frame is about 26 bytes long, and the maximum length of the whole frame is variable but it can be upto 1500 bytes long. So the maximum efficiency is about 98.3% efficient.
