Find Your Estimated Intimissimi Bra Size
Enter your measurements to get a quick size estimate in Intimissimi-style sizing, plus sister sizes for fit adjustments.
Important: This is an estimate, not an official brand tool. Different bra styles (balconette, plunge, triangle, bralette) can fit differently even in the same size.
How this Intimissimi bra size calculator works
This calculator uses two measurements: underbust and full bust. It estimates your band size by rounding your underbust to the nearest EU band increment (5 cm), then estimates cup size from the difference between bust and underbust.
Since Intimissimi collections may show different labeling systems across regions, your result includes:
- EU/IT-style size (example: 75C)
- Numeric Intimissimi estimate (example: 3C)
- UK/US equivalent (example: 34C)
- Sister sizes for tighter or looser band preferences
How to measure correctly
1) Snug underbust
Wrap a soft measuring tape around your ribcage, directly under the bust. Keep it level and snug, but not painfully tight. Exhale normally before reading the number.
2) Full bust
Measure around the fullest part of your bust with the tape level all around your back. Keep your arms relaxed and avoid pulling the tape too tight.
3) Enter numbers exactly
If you are between values, enter decimals (like 73.5 cm). Small differences can change cup size recommendations.

How to check if your bra size is actually right
- Band: Sits level and firm around your body without riding up.
- Cups: No spilling, no gaping, and breast tissue sits inside the cup.
- Center gore: Lies close to the sternum (for wired bras).
- Straps: Stay in place without digging into shoulders.
- Comfort: You can breathe and move naturally.
Common fit fixes using sister sizing
If your cup feels right but the band feels off, try sister sizes:
- Band too tight: Go up one band size and down one cup (e.g., 75C → 80B).
- Band too loose: Go down one band size and up one cup (e.g., 75C → 70D).
FAQ
Is this calculator official from Intimissimi?
No. This is an independent sizing helper based on common lingerie fitting conventions.
Why do I get a different size in different bras?
Different cuts, fabrics, and construction methods can change fit. For example, push-up bras often feel tighter in the cup than soft-cup styles in the same labeled size.
Should I trust tape measurements or in-store fitting?
Use both. Start with measurements, then confirm by trying on several sizes around the estimate.
Final tip
Your best bra size is the one that gives you stable support and all-day comfort. Use this calculator as your starting point, then fine-tune with real fit checks and sister sizes.
