Measuring a woman’s chest size typically involves two key measurements: the bust measurement and the band measurement. These measurements are used to determine both the cup size and the band size, which together make up the bra size. Here’s how to measure each:
1. Band Size (Underbust):
– Stand in front of a mirror, wearing a well-fitting bra or no bra at all.
– Use a soft, flexible measuring tape.
– Wrap the measuring tape around your ribcage, just under the bust. Make sure the tape is level all the way around and snug but not tight.
– Take the measurement in inches. If the measurement is an even number, add 4 inches to it. If it’s an odd number, add 5 inches. This will give you your band size.
Example: If your underbust measurement is 30 inches:
– 30 inches + 4 = 34 (your band size).
2. Bust Size:
– Now, measure around the fullest part of your bust. Keep the tape comfortably snug but not tight.
– Make sure the tape runs across your back and stays level all the way around.
– Note the measurement in inches.
Example: If your bust measurement is 38 inches, note that down.
3. Calculating Cup Size:
– To find your cup size, subtract your band size measurement (from step 1) from your bust measurement (from step 2).
– The difference between the two numbers corresponds to the cup size. Here’s the standard cup size chart:
– 1-inch difference = A cup
– 2-inch difference = B cup
– 3-inch difference = C cup
– 4-inch difference = D cup, and so on.
Example: If your bust measurement is 38 inches and your band size is 34 inches:
– 38 – 34 = 4 inches.
– This means your cup size is D.
4. Final Bra Size:
– Combine the band size and cup size to get your full bra size. Using the example above, if your band size is 34 inches and your cup size is D, your bra size would be 34D.
It’s important to note that bra sizing can vary slightly between brands, so it’s always a good idea to try on different sizes or consult the brand’s specific sizing chart when purchasing a bra.
