16E Bra Size Conversion: AU, US, UK and EU Explained Simply
16E is a very normal Australian bra size, but the second you shop across different countries or brands it can get needlessly annoying. What looks like a simple size in Australia becomes 36DDD on one site, 36E on another, and 80F on a European chart. Same general fit target, different labelling systems, and too many chances to order the wrong thing.
The good news is that 16E is one of the cleaner conversions once you know the pattern. The messy part is not the maths. It is the fact that brands still label fuller cups differently and fit shapes vary more than most charts admit.

Why 16E can still fit differently between brands
Because size is only half the story. Cup depth, wire width, strap placement, band firmness, and whether the bra is plunge, full cup, balconette, or wirefree all change how that size behaves. Two bras can both say 16E and still feel like they were designed by people who have never met each other.
That is why one bad 16E does not automatically mean your size is wrong. It might just mean the shape is wrong, or the brand has a looser band than average.

Sister sizes for 16E
- 14F for a firmer band
- 18DD for a looser band
These are useful when stock is limited or a specific band runs tight or loose, but they are still backup options. They are not proof that sizing charts have feelings.

What is 16E in US sizing?

What if 16E feels loose in the band?
Try 14F as a sister size if the cups feel right but the band is too relaxed.
