Why Not All HH Cup Bras Are the Same
Although HH cup is a recognised UK bra size, not all HH cups have the same volume. Different brands use slightly different UK cup letter sequences, even though the underlying sizing rule remains consistent.
Cup sizes are based on the difference between the band measurement and the fullest bust measurement. Each 1 inch increase equals one cup size in UK sizing.
The measurements increase in exactly the same way across UK sizing systems — only the letters used to label each step may differ. This means cup letters should not always be compared directly between brands without checking the sizing system being used.
The HH cup is part of the UK’s extended bra size sequence, which includes several double-letter cup sizes such as FF, GG and HH. These represent additional steps in the progression rather than half sizes. For a full explanation of how these sizes fit into the UK system, see our Double Cup Bra Size Guide .
If you are wondering what this size looks like in practical terms, see our guide explaining how big HH cup sizes are and how cup volume changes across different band sizes.

How Big Is an HH Cup?
A UK HH cup bra sits within the fuller-bust range of the UK cup size sequence. However, how large an HH cup appears depends on factors such as band size, body proportions and bra design.
For example, a 30HH and a 40HH do not have the same cup volume. Cup volume increases as band size increases, which is why the cup letter alone does not tell the full story.

HH Cup Size Progression
An HH cup sits between H and J in the extended UK cup size sequence used by many fuller-bust brands. The diagrams below show how cup volume increases gradually while the band size remains the same.
HH sits between H and J in the UK bra size sequence.
These simplified educational diagrams show how cup volume increases across nearby UK cup sizes when the band size stays the same.
Cup volume increases gradually across the UK sizing system. A 34J has more cup volume than a 34HH, while a 34H has slightly less.
How cup sizes actually work: Bra cup sizes are based on a simple fitting rule — each step in the cup sequence represents a 1 inch difference between the bust and underbust measurement. This rule applies across all UK brands, regardless of whether they use a traditional or extended cup letter sequence.
In brands that use an extended UK cup sequence, HH is a separate cup size positioned between H and J. Each step represents the same one-inch increase in measurement difference, making HH one cup size larger than H and one cup size smaller than J.
The difference between brands is the lettering used, not the size step itself. For example, some traditional UK cup sequences move directly from H to J, while extended UK sizing includes HH as an additional cup size between them.
UK vs US Bra Sizes
Bra sizing systems vary slightly between regions. Most specialist fuller-bust brands such as Panache, Freya, Fantasie and Elomi follow the UK cup size sequence, which includes double letters such as FF, GG and HH.
Some US brands use a slightly different lettering system, which can create confusion when comparing sizes internationally. To understand how the sizing systems relate, see our UK vs US bra size comparison guide .
Is a UK HH Cup the Same as a US HH Bra Size?
It depends on the brand. Many UK-based fuller-bust brands such as Panache, Freya and Elomi use the same extended UK cup sequence internationally, meaning an HH cup is labelled the same in both the UK and US.
However, some US lingerie brands follow a different cup progression. For this reason, always check the brand’s stated sizing system rather than relying on the cup letter alone.
A cup size is not one fixed volume. Cup volume increases as the band size increases, so a 30HH, 34HH and 40HH are all very different in fit and capacity, even though the cup letter is the same.
Always consider both band size and cup size together when comparing bras.

HH Cup Volume Changes With Band Size
Many people assume that all HH cups are the same size. In reality, cup volume increases as band size increases. A 38HH holds more volume than a 34HH, while a 30HH holds less.
The cup letter stays the same, but overall cup volume increases as the band size increases.
These simplified educational diagrams show how cup volume changes as the band size increases, even when the cup letter remains HH.
A bra size consists of both the band size and cup size. A 38HH holds more cup volume than a 34HH, while a 30HH holds less, despite all three using the same cup letter.

How to Find Your Correct HH Cup Size
Accurate measurements are essential at HH cup level. Measure your underband and bust carefully, then enter your details into our Bra Size Calculator.

Common Fit Issues for HH Cup Bras
- Band riding up at the back (often means the band is too big)
- Cups gaping (often shape-related, not always “too big”)
- Spillage at the top edge (often means the cup is too small)
- Wires sitting on breast tissue at the sides
- Straps digging in or slipping off
If your HH cup fit feels inconsistent, try another style within the same brand or compare brands using our Bra Size Converter.
Can I Sister Size Instead of Wearing an HH Cup?
Sister sizing can help if your exact size is unavailable in a specific style, but it should be used carefully. If you go up a band size, you usually need to go down a cup size to keep a similar cup volume (and vice versa). However, sister sizes can change where wires sit and how the bra supports you, especially across different shapes.
HH Cup Sister Size Example
When sister sizing, the band size changes while the cup volume stays similar. A common HH cup example is:
These sizes have a similar cup volume, but different band lengths.
Sister Size Comparison
These diagrams provide a simplified visual example of sister sizing. While the band size changes, the overall cup volume remains broadly similar.
Sister sizes can help when your usual size is unavailable. As the band size increases, the cup letter decreases to maintain a similar cup volume.
For a full explanation of how sister sizing works, see our Bra Sister Sizes Guide .
