All About the Bra Cup Sizes


It is always a question for us to know what my bra size is... What are the available ones, and what is perfect for me?
There are many bra sizes available, which start from A to L and also from 26 to 58. What you need to figure out is which one is suitable for me and how to find the right one.
An A Bra Size—It is the smallest cup size, ideal for women with a 1-inch difference between the band and bust measurements.
B Bra Size – Slightly fuller than A cups, B cup bras are designed for women with a 2-inch difference between band and bust.
C Bra Size – A common size offering balanced support and shape, suitable for a 3-inch difference.
D Bra Size – Fuller bust size with a 4-inch difference, offering more support and coverage.
DD Bra Size – Also known as E in some brands, DD is for a 5-inch difference and offers enhanced support.
E Bra Size – Equivalent to DD in most cases, ideal for those with a 5-6 inch difference between band and bust.
F Bra Size – Fuller bust with a 6-7 inch difference requires specialized support and wide straps.
G Bra Size – One of the larger sizes, designed for a 7-8 inch difference, offering maximum support and comfort.

Part of Bra | Fit Check |
Straps | The straps should rest comfortably on your shoulders without digging in or slipping off. If they dig in, they may be too tight, or the band may be too loose. |
Slider | The slider is used to adjust the strap length. Ensure that it is positioned so that the straps provide lift without causing discomfort. |
Upper Cup | The upper cup should sit smoothly against your breast without any gaping or digging in. Gaping means the cup might be too large; spillage indicates it’s too small. |
Apex | The apex, where the straps meet the cups, should lie flat against your skin without pulling or puckering. |
Center Gore | The center gore should lie flat against your sternum. If it lifts away, the cups might be too small or the band too loose. |
Side Seam | The side seams should sit comfortably along your torso without twisting or digging in. |
Cup Side | The cup side should fully encase your breast tissue without any spillage on the sides or under the arms. |
Underwire | The underwire should sit comfortably around the base of your breast without digging into your skin or sitting on top of breast tissue. |
Cup Seam | The cup seam should not create discomfort or visible lines under clothing and should help shape the breast naturally. |
Under Cup | The undercup should provide support, especially for fuller breasts, ensuring the breast tissue is fully encased without spillage. |
Underband | The underband should sit level around your torso, parallel to the ground, and be snug enough to provide support without digging in. |
Wing | The wing should lie flat against your sides without bulging or causing discomfort, providing smooth support along the torso. |
Back | The back of the bra should sit level with the front and not ride up. If it does, the band is too loose, and a smaller band size may be needed. |
Ring | The ring where the straps attach to the bra should be secure and not cause irritation or dig into the skin. |
Hook & Eye | The hook & eye closure should be fastened on the loosest hook when new, allowing for tightening as the bra stretches over time. |
Raised Edges | Raised edges, especially along the wings or band, should lie flat and not create bulges or discomfort. |
