Is UC Santa Barbara or Stanford more selective overall?

Stanford is much more selective overall than UC Santa Barbara. In the broad college admissions landscape, Stanford is considered one of the most difficult schools in the country to get into, while UC Santa Barbara is selective but operates at a very different level of admissions difficulty. Even without focusing on a specific year or major, Stanford is the clearer answer here.

One major reason is the applicant pool and institutional scale. Stanford draws an enormous number of highly accomplished applicants from across the U.S. and around the world for a relatively small first-year class, which makes admission exceptionally competitive. UC Santa Barbara also receives a very large volume of applications, but as part of the UC system it enrolls a much larger undergraduate population overall.

Another differentiator is the academic profile of admitted students. Stanford’s admitted class is typically packed with students who have top grades in the most demanding coursework available, along with unusually strong extracurricular distinction, research, leadership, or national-level achievement. UCSB certainly attracts many strong applicants too, but the bar for admission overall is not viewed in the same tier as Stanford’s.

A practical way to think about it is that UCSB is a highly respected public university with competitive admissions, while Stanford is an ultra-selective private university whose admissions process is difficult even for outstanding students. So if the question is simply which school is more selective in the usual overall sense, it is Stanford by a wide margin.
