Classroom size absolutely matters, at the extreme you encounter Bloom's 2 sigma[0] around ratios of 3:1. Small classes get you two things:
1. Easier classroom management
2. More individualized education
(1) is good and has some effect, but (2) is the meat and potatoes. I will grant the effects are not linear and so haggling about 16-24 kids may not be worth it but the difference between 20 kids and 10 is enormous.
