I don't know a lot about it, but I think Puerto Rico is the size of any of the Cuban provinces at most. And surprise, it was Puerto Rico that copied the Cuban flag, I had to go to Wiki to find out about this one: Juan de Mata Terreforte, an exiled veteran of "El Grito de Lares" and Vice-President of Puerto Rican Revolutionary Committee, in New York City, adopted the flag of Lares as the flag of Puerto Rico until 1892, when the current design, modeled after the Cuban flag, was unveiled and adopted by the committee.
