What is the Ucla school size?

UCLA's size depends on what you mean by "size." There's no single number.

* Student Body: UCLA has over 45,000 students, making it one of the largest universities in the United States. The exact number fluctuates slightly year to year.

* Campus Size: The UCLA campus is approximately 419 acres.

Therefore, to answer your question accurately, you need to specify what aspect of "size" you're interested in (student population, campus area, number of faculty, etc.).
