E Cup Bras by Band Size (UK) – Find the Best Bras for Your Exact Band Size

This E cup bras by band size guide helps you find the individual guide for your exact band size, with links to detailed pages for each available UK E band size.

An E cup sits within the UK bra sizing system between DD and F. However a 28E, 34E and 40E represent different cup volumes because cup size changes with band measurement.

If you want to understand the size itself before choosing a band, see our E Cup Bras Guide or explore real-world measurements in our How Big Are E Cups explanation.

If you are unsure of your starting size, begin with the Bra Size Calculator. You can then confirm your fit using our Bra Fitting Advice and compare sizing across brands using the Bra Size Converter.

What Is an E Bra Size?

An E bra size is part of the UK bra sizing system and sits between DD and F in the cup progression.

In most UK size charts, an E cup corresponds to roughly a 6 inch difference between the band measurement and the fullest bust measurement. Each step in the UK cup sequence typically represents about a 1 inch increase in this difference.

Cup size is not a fixed volume on its own. A 30E, 34E and 40E all represent different cup volumes because cup volume increases as the band size increases.

For a clearer picture of measurements and volume, see our How Big Are E Cups guide.

You can also compare E with neighbouring cup sizes using our DD vs E vs F Cup Size Comparison or explore the wider UK sequence in our UK Bra Cup Size Chart.

If you are comparing different band sizes while keeping a similar cup volume, use our Bra Sister Sizes Guide or Bra Sister Size Calculator.

You can also explore detailed E-size guides for 32E, 34E and 36E.

Why Band-Specific E Guides Matter

Cup volume increases as band size increases. This means a 40E has more cup volume than a 30E, even though both use the same E cup letter.

Because band size and cup size work together, looking at the exact band-and-cup combination gives a clearer picture than considering the cup letter alone.

For example, a 32E bra, 34E bra and 36E bra all use an E cup letter, but each represents a different band measurement and overall cup volume.

Our E cup bras by band size directory brings together the available UK E sizes from 28E to 56E, making it easier to move directly to the guide for your exact band-and-cup size.
