As a general rule of thumb, a 12000 BTU air conditioner will cool a room from 450-550 square feet. Generally, we recommend that you buy a portable air conditioner that is a bit bigger than the recommended size. This is a good idea because a portable ac unit does not cool quite as well as a window air conditioner or a split ac.
Your best bet, therefore, is to use a 12000 BTU portable ac unit in a room that is 400-450 square feet. For window units, you don’t need to make such concessions.
