Measuring your breast size is all about knowing your under-bust measurement. And your over-bust measurement.
For this exercise, you will need the tape measure.
Step 1 – Wear a Non Padded Underwire Bra
Put on your best fitting non padded underwire bra. You want an underwire bra to support the breasts. And to keep them upright when measuring them. More over, you want an unpadded bra so that you get an accurate measurement. If you wear a padded bra, your measurements will be skewed upwards because of the padding.
Step 2 – Measure your Band Size
Next, you have to measure your band size. Take the tape measure and wrap it around your back right under your bust. Think tribcage level. Hold the tape meaure firmly using both sides ensuring its neither too tight nor loose. Also ensure the tape measure lies flat on the skin and goes across the back. Where the tape measure meets is your band size. From our results, the band size was 30 inches. If you have an odd number, round it up. For example, if you find that you are 40.5 inches, round it up to 41. On the same note, if you have a 38 or below inch, add two. For example, in our case, the size was 30 inches. We will add 2 inches so that it becomes 32.
Step 3 – Measure your Bust Size
Slide the tape to the fullest past of your bust. The tape should be snug but not tight. If you get an odd number, round it up. From our results, the bust size was 35.3 inches, which we rounded up to 36 inches.
Step 4 – Find your Cup Size
The cup size is the difference between the bust size and the band size. In our case, the bust size 36 inches minus the band size 32 inches leaves us wirh 4 inches. After getting your results, refer to the following chart for your bra size. In our case, the bust size was 36 inches and the band size was 32 inches. Therefore, the difference is 4 inches. When you look at the chart, 4 inches is a D cup. Therefore, the size of a bra is 36D. And that’s how you measure your bra size.
