What is 30H Bra Size? Fit Guide for Petite Frames

Understanding 30H Breast Size: Support, Fit, and Confidence for Full Busts

For women with a 30H bra size, finding lingerie that fits beautifully and supports comfortably can be a challenge. This size represents a narrow band with a high-volume cup, and it’s more common than you might think—especially among women with naturally full busts and petite frames.

In this guide, we’ll break down what it means to have a 30H bust, how to find bras that fit this size correctly, and what makes 30H bras so essential for comfort, posture, and style.

While some search online using terms like "30H tits" to describe fuller busts, what truly matters is having the right information—and the right fit—for your body.

What Does 30H Actually Mean?

Bra sizing consists of two key measurements: the band and the cup.

30 Band: Indicates the measurement around the ribcage, typically 28–29 inches. This size suits women with petite or slim torsos.
H Cup: Refers to the difference between the bust and underbust measurements—about 11 inches. H cups are part of the extended size range and provide ample volume for fuller busts.

In simple terms, a 30H breast size means a smaller frame with a significantly fuller chest—a combination that requires intelligent support and shaping.

Common Fit Challenges for 30H Breasts

❌ Bands That Are Too Loose

Most stores carry 34+ band sizes, leaving 30H women with options that ride up or don’t offer enough anchoring.

❌ Straps Doing All the Work

Without a snug band, straps take the weight—leading to shoulder pain and poor posture.

❌ Cup Spillage or Gaping

A mismatch in cup volume can cause overflow, flattening, or gaping.

What to Look for in a 30H Bra

✅ Firm, Snug Band

A well-fitted 30 band sits level around the body and does most of the lifting.

✅ Supportive Cup Design

Full cups, balconettes, and three-part seamed cups provide lift, shape, and containment.

✅ Strong Underwire or Structured Wireless

Underwire helps shape and support the bust, while some high-performance wireless bras also work well when designed for full busts.

✅ Wide Straps and Wings

These help distribute weight evenly and reduce strain on the back and shoulders.
