A law school's size is determined by its student population. Small law schools are usually, about or below, 400 students. A smaller school will usually have smaller class sizes although that depends on the number of professors. You will usually get to know your class better in smaller schools. Also when you need to see the Dean or other Administrators it will be much easier than in larger schools. Also, smaller law schools tend to have less formal processes for administrative matters such as obtaining internships, visiting other law schools, summer abroad programs, etc. making it easier to obtain beneficial results. In addition you will often get to know your professors better as they have more time for one on one communication and assistance. Many of the best and most well known law schools tend to be large schools. If you learn better in a smaller classroom where you can get professors to help you and do not have to rely on Teacher's Assistants than you may want to seriously consider a smaller school. However, if you learn better on your own than a larger school may be where you do best and may have a better reputation.
