Let’s dive into everything you need to know about US bra sizing.
Understanding the US Bra Sizing System
The bra size chart US uses a combination of numbers and letters to indicate your perfect fit. The number represents your band size (the measurement around your ribcage), while the letter indicates your cup size (the difference between your bust and band measurements).
Here’s how the system breaks down:
- Band sizes typically range from 28 to 54 inches
- Cup sizes progress from AA through O and beyond
- Each cup size represents approximately one inch of difference
The US sizing system differs from other international standards, making it essential to understand these measurements.

A friend to help (optional but recommended)
Step by Step Measuring Process
Measuring Your Band Size:
- Stand straight in front of a mirror wearing your best fitting bra.
- Wrap the measuring tape around your ribcage, directly under your bust.
- Keep the tape snug but not thigh, you should be able to breathe comfortably.
- Take a deep breath in and out, allowing the tape to find its natural position.
- Record this measurement to the nearest quarter inch.
Measuring Your Bust Size:
- Keep the tape around your back at the same band level.
- Bring it around to measure at the fullest part of your breasts.
- The tape should lie flat against your back and cups.
- Don’t pull too tight, the measurement should feel snug but comfortable.
- Record this number to the nearest quarter inch.
Quick Measurement Tips.
- Measure yourself at the same time each day for consistency.
- Consider having measurements taken monthly, as body changes can affect size.
- Always measure while wearing a properly fitted, non-padded bra.
Decoding Cup Sizes: From A to Beyond
Cup sizes in the bra size chart US represent the difference between your bust and band measurements. Here’s how it works:
Difference (inches) US Cup Size.
| Difference (inches) | US Cup Size |
| Less than 1 | AA |
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |

| 6 | DDD/F |
| 7 | DDDD/G |
| 8 | H |
| 9 | I |

Understanding Larger Cup Sizes
Many women don’t realize that cup sizes extend far beyond D. If you’ve been wearing a 36D but experience spillage or discomfort, you might actually need a 34DD or 32F. The US bra sizing system accommodates cup sizes up to O and beyond, ensuring every woman can find her perfect fit.
Sister Sizing Explained
Sister sizes maintain the same cup volume while adjusting the band size. For example:.
- 34B = 32C = 36A (same cup volume, different band sizes).
- 36D = 34DD = 38C.
This concept helps when your exact size isn’t available or when you need slight adjustments for comfort.
Band Size Chart and What It Means
Your band size provides 80% of your bra’s support, making it crucial to get this measurement right. The band should feel snug on the loosest hook when new, allowing you to tighten it as the bra stretches with wear.

Common Bra Size Chart US Mistakes to Avoid
Mistake # 1: Adding Inches to Your Band Measurement.
Old fitting methods suggested adding 4-5 inches to your underbust measurement. Modern bra size charts recommend using your actual measurement for better support and comfort.
Mistake # 2: Assuming You’re a “Standard” Size.
Many women default to sizes like 34B or 36C without proper measurement. These might not be your true size – take the time to measure correctly.
Mistake # 3: Ignoring Size Variations Between Brands.
A 34C in one brand might fit like a 32D in another. Always try on bras or check individual brand sizing guides.
Mistake # 4: Not Considering Shape Differences.
Two women with the same measurements might need different styles based on breast shape. Consider whether you have:.
- Full on top or bottom.
- Wide or narrow-set breasts.
Projected or shallow shape.
