Find the right band size
To find your band size, put on a non-padded bra that fits you well. Find a measuring tape, and stand in front of a mirror. Wrap the tape around your body just underneath your bust. The measuring tape should be horizontal to the floor, and quite snug. The measurement in inches is your band size. If it’s an odd number, round down to the nearest even number.
To find your bust size, measure around the fullest part of your breasts. Take this measurement and subtract the band measurement, e.g. if you measure 31 underneath your breasts, and 34 around, the result is 34-31 = 3. Use the result to find your cup size here:
Cup size = Bust size – Band size:
0 = AA <1 = A 1 = B 2 = C 3 = D 4 = DD 5 = DDD/E 6 = F 7 = G 8 = H
Please note that this guide only gives you an estimate to your bra size, as sizes may vary between different bra manufacturers.
Bra Size Calculator
This easy-to-use bra size calculator helps you to quickly determine your correct bra size in various international sizing systems, including U.K., U.S., and other European sizes. All you need to do is take measurements of your bust and underbust sizes in inches or in centimetres. Input those numerical values in the calculator and then simply click “Calculate” to generate results.

2. FIND YOUR OVERBUST SIZE
➄ Measure over the bust points in a straight line to get the overbust width, this determines your cup size. ➅ Hold the measure tape loosely around the largest part of your breasts. ➆ Again, keep the tape parallel to the floor. Use a mirror or ask someone to help you.

Bra Cup Size Conversions
Cup sizes are determined by calculating the difference between over bust (where the bust is the fullest) and under bust measurements. For example: Over bust 85 cm and under bust 70 cm gives the difference of 15 cm, which gives an European B-cup. If the under bust measurement it rounded down, then always base the difference calculation on this rounded number. For example: For measurements over bust 85 cm and under bust 74 cm the difference would seem to be 11 cm. However, we must round down 74 to 70, so the difference is calculated as 85-70=15 cm.
US and UK cup sizes are divided in steps of 1 inch, JP and KO in steps of 2.5 cm (almost but not exactly 1 inch), while the rest in steps of 2 cm. (1 inch = 2.54 cm.)
Be careful of alternative sizing. AU, NZ and IT cup sizes were originally divided in steps of 2.5 cm (almost but not exactly 1 inch). Nowadays, most producers from these countries have adopted the EU / International bra cup sizing convention which is de facto becoming the new standard. However, there are still producers using the 2.5 cm cup size steps.
Precise Conversion (Recommended)
The cup size steps (1 inch and 2 cm respectively) are significantly different and so are the offsets and overlaps, much more so than in band sizes. The Internet is filled with conversion tables that ignores this and are therefore completely wrong, especially in sizes above D-cup. The following is a precise and accurate conversion table for bra cups. It’s highly recommended to use this table over approximative tables.
Cup sizes do not convert cleanly and precisely. For every four cup sizes based on inches there are five sizes based on centimeters. This means that some sizes convert into a several. The tables below convert sizes with the starting point of the cup steps being 2 cm (EU/Int/AU/NZ/FR/ES/BE/IT), 2.5 cm (JP/KO) and 1 inch (US/UK) respectively. Using three tables makes the conversion process easier. Please note that the precise method above is recommended.

Convert bra cups from US/UK to EU/Int/AU/NZ/FR/ES/BE/IT and JP/KO:
If I wear a ##XX size on brand Y what size I am on brand Z?
You have to try it. If you wear a 38F on one brand, this should be the first size you try on another brand if they have the same size available and see from there.
If the brands use different sizing systems, or even worse, different grading systems. Then it will be inaccurate to make just a straight conversion to find your fitting bra. We recommend doing a comparison by bra measurements to get an idea. For example if you wear a 38H in Freya, chances are that a 85H will fit not fit you in Comexim because these two brands not only use different band and cup sizing, but also use different cup grading, so any conversion will be off.
But, what if I count the cups, could I make the conversion?
