This calculator helps nursing mothers find their correct bra size for comfort and support during breastfeeding.
It uses standard measurements to recommend a size that accommodates changes in breast volume.
Use it to avoid discomfort and ensure proper fit for daily activities.
Nursing Bra Size Calculator
Enter measurements and click Calculate to see your recommended bra size.
How to Use This Tool
Measure your underbust snugly just below your breasts and your bust at the fullest part. Select your current breastfeeding stage and preferred bra style from the dropdowns. Click Calculate to see your recommended size, and use Reset to clear all fields.
Formula and Logic
The calculator rounds your underbust to the nearest even number for the band size. The cup letter is determined by the difference between bust and underbust measurements (e.g., 1 inch = B, 2 inches = C). Adjustments are made based on breastfeeding stage and style preferences.
Practical Notes
- Measure in the morning when breasts are less swollen for accuracy.
- Consider buying a bra with adjustable hooks for flexibility as your size changes.
- Wireless styles are often more comfortable during early breastfeeding.
- Check for stretch in the fabric to accommodate milk supply fluctuations.
- Budget for 2-3 bras to rotate and wash regularly.
Why This Tool Is Useful
Proper bra fit reduces discomfort, prevents back pain, and supports milk production. This tool simplifies the process for busy mothers, helping them make informed decisions quickly without needing professional fittings.
