While you can choose as many or as few adjectives as you see fit, in some cases, the number of adjectives you choose will affect your outcome. If you choose fewer than six or more than 80 adjectives, the results will not be accurate. Ideally, you should choose between 12 and 50 adjectives on each list. By choosing within this range, you will give enough adjectives to create a picture of who you are and allow for comparison between lists.
