GANNI uses European sizing as its base. The current official size guide maps clothing from EU 32 to EU 52 and says the chart is built around a standard height of 170 cm plus or minus 4 cm, so treat it as a starting point and confirm the exact item on the product page.

Official starting point
GANNI's public guide is mainly a conversion chart, not a full bust, waist, and hip reference sheet. The brand says exact style measurements and measurement guidance live on each product page, and its FAQ says clothing pages include a Size Guide link plus a Fit Finder for more tailored recommendations.

How to read GANNI jeans sizes
The main size guide gives the overall brand conversion, but current denim listings also show jeans in waist-and-length formats such as 24W/33L through 32W/33L. GANNI's denim guide says straighter and cropped fits sit closer to the base size, while baggy and wide fits are intentionally roomier, so cut matters as much as the number.
GANNI shoe size chart
GANNI shoes use EU sizing in the official shoe chart.

| 36 | 6 | 3 | 230 |
| 37 | 7 | 4 | 240 |
| 38 | 8 | 5 | 250 |

What product pages add
The master chart will not tell you whether a specific piece is close through the chest, loose at the waist, or adjustable. For example, a current dress page describes a regular chest fit with a looser, belt-adjustable waist. That is why two GANNI items in the same labeled size can still wear differently.
How to choose between two sizes
If you are between sizes, start with the EU conversion chart, then check the exact product page and the Fit Finder guidance. GANNI's own materials make clear that cut, fabric, product line, and even the regional size label you are viewing can change how the item reads on the page and on your body.
Measure the item you already like
Because the public master guide is a conversion chart rather than a full garment-measurement table, compare the new item's product-page details with a similar piece you already own. Lay that garment flat and note the dimensions that matter for the silhouette, such as chest width, waist position, rise, inseam, or total length. Then use the exact style notes and measurement guidance on the current GANNI product page. This is more useful than assuming one EU label will fit identically across a fitted dress, an adjustable-waist style, and oversized denim.
Check the region and item before checkout
Confirm that the store region, product color, and selected size shown in the cart match the page you used for sizing. Regional pages may display different label systems even when the underlying EU size is the same, while availability and fit notes belong to the exact item. Reopen the page's Size Guide and Fit Finder immediately before ordering, especially if you switched country sites, colors, or cuts while comparing options. Save the product-page details with the order so you can distinguish a conversion mistake from a style-specific fit issue later.
Bottom line
Use GANNI's EU chart first, then trust the specific product page for the final call. The official guide gets you close, but the item-level fit note is what keeps you from buying the right number in the wrong silhouette.
