what is ratio of useful data to the entire packet for the smallest ethernet frame?
- 3 months ago
The minimum Ethernet frame size is 64 bytes and the maximum size of the frame is 1518 bytes. This includes all bytes from the Destination MAC Address field through the Frame Check Sequence (FCS) field excluding Preamble field. The Preamble field is not included when describing the size of a frame.
Every less than 64 bytes in length has considered a “runt frame/ runt packet” or “collision fragment” and the receiving stations automatically discard these frames and frames with more than 1500 bytes of data considered “jumbo” or “baby giant frames”. If the frame is less than or greater than above mention size, the receiving device drops and discard the frames.

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.
