What cup size is a 4-inch difference? A 4-inch difference between the band size and bust measurement typically corresponds to a D cup size in the U.S. bra sizing system. This means if your band size is 34 inches and your bust measures 38 inches, you would likely wear a 34D.
Understanding Bra Sizing
Bra sizing can be confusing, but understanding the basics can help you find the right fit. A bra size consists of a number and a letter, such as 34D. The number represents the band size, while the letter represents the cup size. The cup size is determined by the difference between the band size and the bust measurement.
How to Measure Bra Size
-
Measure Your Band Size: Wrap a measuring tape snugly around your ribcage, just under your bust. Make sure it’s level and record the measurement in inches. If the number is even, that’s your band size. If it’s odd, round up to the nearest even number.
-
Measure Your Bust Size: Measure around the fullest part of your bust, keeping the tape level. Record this number.
-
Calculate the Difference: Subtract the band size from the bust measurement. The difference in inches determines the cup size.

Why Accurate Bra Sizing Matters
Wearing the correct bra size is crucial for comfort and support. An ill-fitting bra can cause discomfort, back pain, and even affect posture. Here’s why getting the right size matters:
- Comfort: A well-fitted bra reduces discomfort and skin irritation.
- Support: Proper support can prevent sagging and reduce back strain.
- Appearance: The right size enhances your natural shape and improves how clothes fit.
Common Bra Sizing Mistakes
- Band Too Loose: If the band rides up your back, it’s too loose. The band should fit snugly on the loosest hook.
- Cups Too Small: If you experience spillage over the top or sides, the cups might be too small.
- Straps Too Tight: Straps should not dig into your shoulders; the band should provide most of the support.
Adjusting Bra Size for Different Brands
Bra sizing can vary between brands and countries. Here are some tips for adjusting your size:
- Try Different Brands: Sizes can vary, so try on bras from different manufacturers.
- Check International Sizes: If buying internationally, check conversion charts, as sizes differ between regions.
- Consider Sister Sizes: If you can’t find your exact size, try sister sizes. For example, if you’re a 34D, you might also fit a 36C or 32DD.
Tips for Finding the Perfect Bra
- Get Professionally Fitted: Many lingerie stores offer free fittings.
- Try Before You Buy: Always try bras on before purchasing to ensure a good fit.
- Check for Comfort: Move around to ensure the bra stays in place and feels comfortable.
