The reverse conversion
Going the other way, an EU 32 comes back to a UK 4. Both describe a body with a 78 to 81 cm bust and a 60 to 63 cm waist. See EU 32 to UK for that direction in full.
Why the numbers differ
US and UK women's dress sizes run on the same even-numbered scale offset by four, so a US 0 is a UK 4. Continental Europe counts differently again, which puts the same body at EU 32, and Italy adds a further four on top of the European number, giving 36. None of these describe the garment differently, they are four conventions for one set of measurements: a 78 to 81 cm bust and a 60 to 63 cm waist.
That is also why the measurement columns matter more than the label. Vanity sizing has moved US and UK numbers down over the decades while European numbers stayed closer to the underlying body measurements, so two garments both labelled UK 4 can differ by several centimetres in the bust. Measure across the fullest part of the bust and the narrowest part of the waist, then pick the row that matches, rather than trusting the size you usually buy.
This chart follows the widely published international women's clothing conversion tables and the body-measurement approach behind the EN 13402 European sizing standard.

Common questions
What is UK size 4 in EU?
A UK 4 women's clothing size is an EU 32, which is a size XS with a bust of 78 to 81 cm and a waist of 60 to 63 cm.
Is UK 4 a small, medium or large?
A UK 4 is a size XS on the letter scale. Letter sizes cover a wider band than numeric ones, so a XS spans more than one numeric size in most ranges.
What measurements does a UK 4 fit?
A bust of 78 to 81 cm and a waist of 60 to 63 cm. Measuring is the reliable check, because vanity sizing means the same label can be cut two sizes apart between brands.
What if I am between two sizes?
Size up for woven fabrics such as dresses, shirts and tailored jackets, where there is no give. For stretch knits the smaller size often fits better, since the fabric takes up the difference.
