Complete Bra Size Calculator Guide

Finding the perfect bra size is essential for comfort, support, and confidence. Our professional bra size calculator provides accurate measurements for US, UK, and EU sizing systems, helping you discover your ideal fit across all major brands.

Why Accurate Bra Sizing Matters

Studies show that up to 80% of women wear the wrong bra size. An ill-fitting bra can cause discomfort, back pain, poor posture, and reduced confidence. Our calculator uses professional fitting techniques to ensure you get the support and comfort you deserve.

International Size Conversion

Shopping for bras internationally can be confusing with different sizing systems. Our calculator automatically converts between US, UK, and European sizes, making it easy to shop from any brand worldwide. Whether you're buying from Victoria's Secret, Marks & Spencer, or European lingerie brands, we've got you covered.

Understanding Sister Sizes

Sister sizes have the same cup volume but different band measurements. For example, 34C, 32D, and 36B are sister sizes. This knowledge helps you find alternatives when your exact size isn't available and ensures a better fit across different brands.

Professional Measuring Techniques

Our calculator uses the same methods employed by professional bra fitters. We guide you through measuring your underbust and bust circumference correctly, ensuring accurate results every time. Remember to measure without padding for the most precise calculations.

Works with All Major Brands

Whether you're shopping for everyday bras, sports bras, or special occasion lingerie, our size calculator works with all major brands including Victoria's Secret, Calvin Klein, Tommy Hilfiger, Marks & Spencer, H&M, and luxury European brands. Use our calculator as your starting point for any bra purchase.

Expert Fitting Tips

  • The band should provide 80% of the support - make sure it's snug but comfortable
  • Check that the center gore lies flat against your sternum
  • Ensure no breast tissue spills over the cup edges
  • Adjust straps for comfort - they shouldn't dig in or slip off
  • Try on bras in the afternoon when your body is at its natural size
