Zimmermann uses its own numeric sizing, which can be confusing the first time you shop the brand. The system is consistent and easy to translate once you know it. A Zimmermann 0 is a UK 8 and a US 4, and every step up the ladder adds one UK dress size. Below is the full conversion from the brand’s own size chart, the body measurements behind it, and how the pieces actually fit.
How Zimmermann sizing works
Zimmermann sizes run on a numeric scale from 0 to 4, with a petite 0P below the 0. The numbers map to Australian and UK sizes 8 to 16, so a Zimmermann 1 is a UK 10 and a Zimmermann 2 is a UK 12. Our product pages show the same ladder, labelled in UK sizes. Use the table below as your starting point.
| Zimmermann | AU | UK | US | EU | IT | FR |
|---|---|---|---|---|---|---|
| 0P | 6P | 6P | 2P | 32P | 38P | 34P |
| 0 | 8 | 8 | 4 | 34 | 40 | 36 |
| 1 | 10 | 10 | 6 | 36 | 42 | 38 |
| 2 | 12 | 12 | 8 | 38 | 44 | 40 |
| 3 | 14 | 14 | 10 | 40 | 46 | 42 |
| 4 | 16 | 16 | 12 | 42 | 48 | 44 |

Zimmermann body measurements
These are the body measurements, in centimetres, that each Zimmermann size is cut for. Measure yourself rather than a garment you already own, and go by your fullest measurement.
| Zimmermann | Bust (cm) | Waist (cm) | Hips (cm) |
|---|---|---|---|
| 0P | 79 | 62 | 86 |
| 0 | 84 | 65 | 91 |
| 1 | 89 | 70 | 96 |
| 2 | 94 | 75 | 101 |
| 3 | 99 | 80 | 106 |
| 4 | 104 | 85 | 111 |
Zimmermann denim sizes
Jeans are the exception to the numeric ladder. Zimmermann sells its jeans in waist sizes, so a 26 is cut for a 65 cm waist.
| Denim size | Waist (cm) | Hip (cm) |
|---|---|---|
| 24 | 60 | 86 |
| 25 | 62.5 | 88.5 |
| 26 | 65 | 91 |
| 27 | 67.5 | 93.5 |
| 28 | 70 | 96 |
| 29 | 72.5 | 98.5 |
| 30 | 75 | 101 |
| 31 | 77.5 | 103.5 |
| 32 | 80 | 106 |
Does Zimmermann run true to size?
As a rule, yes. Zimmermann cuts to its own chart, so the size that matches your measurements is the right place to start. A few things are worth knowing. Lined and corseted styles sit close at the bust and waist, so if you are between sizes on a fitted bodice, take the larger one. Relaxed and tiered styles carry plenty of ease, so there is no need to size up for comfort. Swimwear is cut to be snug, as it should be.
How to get the fit right
- Check the size guide on each product page, since the fit notes vary by style.
- For a tailored line, take your true size. For a softer, relaxed line on an unstructured piece, size up one.
- Petite frames should look at 0P and 0. Taller frames will find the maxi lengths carry well.
- If a piece is fitted at the bust and you are unsure, our stylists are happy to advise before you buy.
