Graduate / Application information for a foreign person (the whole essay is to fit in 1 page?) [2]

hello my name is carlos, i know my question could seem dumb for some people but i am writing my essays for application and i have a question about essay length.

the instructions say 1 page double space. Does this mean that the whole essay is to fit in 1 page double spaced or do i write 1 page normal space and then send it double space? my question is because 1 page double space seems so little to fit all the information.

Also another essay says 1/2 page double space that is like 1/4 of a page of regular writing. For someone outside of the United States this doesn't make sense to me please help what is the proper way to interpret this instructions.

thank you
