Italian sizes in EU
Updated: 14 July 2026
IT 46 is European size 40. The rule behind it is simple: IT is EU plus 6. The chart lists every women's size from EU 32 to 54, with the bust measurement as a guide value.
IT and European sizes side by side
| IT | EU / DE | International | UK | Bust |
|---|---|---|---|---|
| 38 | 32 | XXS | 4 | 76 cm |
| 40 | 34 | XS | 6 | 80 cm |
| 42 | 36 | S | 8 | 84 cm |
| 44 | 38 | M | 10 | 88 cm |
| 46 | 40 | L | 12 | 92 cm |
| 48 | 42 | XL | 14 | 96 cm |
| 50 | 44 | XXL | 16 | 100 cm |
| 52 | 46 | XXL | 18 | 104 cm |
| 54 | 48 | 3XL | 20 | 110 cm |
| 56 | 50 | 3XL | 22 | 116 cm |
| 58 | 52 | 4XL | 24 | 122 cm |
| 60 | 54 | 4XL | 26 | 128 cm |
The calculation
The offset is the same across the whole chart: IT is EU plus 6. Both scales run in steps of two, so nothing drifts at the top or the bottom.
That holds for the numbering, not for the cut. How a garment sits is up to the brand. The numbers only tell you which row to look at.

Measure in your underwear with a soft tape. Three measurements are enough:
- Bust: around the fullest part, with the tape level across your back.
- Waist: around the narrowest part, usually a hand width above your navel.
- Hips: around the fullest part of your seat.
Keep the tape snug but not tight. The values in the chart are guide values, not a promise. If you fall between two sizes, go by your bust for tops and by your hips for trousers and skirts.
Common questions
What is Italian size 44 in EU sizes?
IT 44 is European size 38.
How do I convert Italian sizes?
Subtract 6 from the Italian number. IT 46 becomes EU 40.
Do Italian brands run small?
The conversion itself is a fixed offset of 6 numbers. How a garment sits depends on the cut of the brand, not on the scale. Measure yourself and compare with the size chart if you are unsure.
