⚙️ 3. What’s New in Bra Size Calculators (2025 Edition)
Bra size calculators in 2025 are powered by AI, 3D measurement tools, and personalized fit algorithms. These are no longer just based on bust and band measurements; they now analyze shape, weight distribution, and movement.
🔥 Key advancements in 2025:
- AI fit suggestions based on body shape & breast type
- 3D fit simulation using smartphone camera

📏 4. How to Measure Your Bra Size at Home
To use a bra size calculator, you’ll need two accurate measurements:
✅ Band Size (Underbust):
- Use a measuring tape directly under your breasts, around your ribcage
- Keep it snug but not tight
- Round to the nearest whole number (in inches)
✅ Bust Size (Overbust):
- Measure around the fullest part of your breasts
- Keep the tape relaxed and parallel to the ground

Bust size – Band size = Cup size
| Difference (in inches) | Cup Size |
|---|---|
| 1″ | A |
| 2″ | B |
| 3″ | C |
| 4″ | D |
| 5″ | DD or E |
| 6″ | DDD or F |
| … | … |
