It is true that ethernet frames are variable size, but it also states that the maximum payload size is 1500 bytes as the grandparent post says. You need to have some upper limit in order to make hardware that can reliably store and forward packets (as a switch would need to do when forwarding a packet to a slower network).
Ethernet frames larger than 1500 bytes are non-standard and commonly known as "jumbo frames". And as you can guess, they'll only work if all the hardware involved in the link supports the larger frames.
