Yes, a 30B breast size is generally considered small, especially in comparison to larger cup sizes.
Here's a breakdown:
- Band Size: The "30" in 30B refers to the band size, which is below average.
- Cup Size: The "B" refers to the cup size, which is closer to average. A B cup indicates a 2-inch difference between your underbust and overbust measurements.
- Comparison: According to the provided reference, a 30B is considered a small bra size when compared to C and D cup sizes. This is because the cup size reflects the volume of the breast tissue.
Therefore, while not the smallest possible bra size, a 30B is on the smaller end of the spectrum.
