IDK where to put this so here we go

yes, cause according to my memory i've read a few that were genuine and meaningful even though short, and i don't think poems imply number of lines present for it to be called one
here's the poem
Title: Corruption
Overtaken again
But what's the gain?
Doesn't it make you faint?
Your soulless image taint
The trouble is that a 'line' is a bad unit of measurement.
Ex.
A man with a hat, a pan, and a house;
A cow with a rat, a tan, and a mouse.
Is two lines, but
A man with
A hat,
a pan,
and a house;
a cow with
a rat,
a tan,
and a mouse.
is 8 lines, but has the same amount of content.

So, what do you think would be a good unit of measurement, and does my poem, 'Corruption', fit the required measurement?
Would you guys consider poems that only have 2-4 lines a poem at all? Why or why not?
