EU Bra Size Calculator with European Measurement Chart

The European bra sizing system is based entirely on centimeter measurements, making it the most straightforward and internationally applicable system. European sizing is used not only throughout Europe but also in many countries worldwide, including parts of Asia, Africa, and beyond.

The band size in the European system represents your actual underbust measurement rounded to the nearest standard interval. Standard EU band sizes are: 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120 cm. Each band size represents approximately 5 cm increments.

The cup size is determined exclusively by the difference between your overbust and underbust measurements, with each 2 cm representing one cup letter. This metric-based approach provides precision and eliminates the confusion found in other sizing systems.

For example, if your underbust measures 73 cm, you would round to 75 cm band size. If your overbust measures 89 cm, the difference is 16 cm. According to the EU cup progression, 16 cm corresponds to a B cup. Therefore, your European size would be 75B.

• Band Fit Precision: The EU system's metric approach means you can achieve precise band fit. Your band size should be within the tolerance range of your measured underbust. The band should sit horizontally without riding up or digging into your ribs.
• Cup Calibration: Because cup sizes are based on 2 cm increments, the European system offers consistent scaling across all sizes. Cups should contain all breast tissue without spillage or gaps, with the center gore lying flat against your sternum.
• Accurate Measurements: The EU system's precision depends on accurate measurements. Measure both underbust and overbust to the nearest 0.5 cm for the most reliable sizing. Even small measurement variations affect your calculated size.
• Rounding Decisions: If your underbust falls between standard band sizes, choose the size closest to your measurement. If exactly between two sizes (e.g., 72.5 cm between 70 and 75), try both to determine which provides better support and comfort.
• Strap Stability: European bras typically have forward-set or center-set straps. Straps should remain secure on your shoulders without slipping, creating a smooth line under your clothes. Strap position affects the overall fit and support.
• Underwire Position: If wearing an underwired bra, wires should rest against your ribcage at your natural breast crease without digging into breast tissue or underarms. Wire width varies among European manufacturers, affecting overall comfort.
• Hook Position and Longevity: European bras should fit comfortably on the loosest hook. This allows you to tighten progressively as the elastic stretches with wear, extending the bra's lifespan and maintaining consistent support throughout its use.

If your band consistently rides up your back, the band size may be too loose. Try sizing down one band size (e.g., from 80 to 75) and increase the cup by one letter to maintain equivalent cup volume using sister sizing. The band should remain horizontally parallel to the ground.

Breast tissue bulging over the top, sides, or under the arms indicates inadequate cup coverage. Increase your cup size by one or two letters. Alternatively, you may need a bra style with deeper cups or different cup shaping, as individual breast shapes vary significantly.

Empty space inside the cups suggests your cup size is too large. Try decreasing by one cup letter. However, different European brands and styles fit differently. Some bras simply don't suit your particular breast shape, so experimentation helps identify the best fit.

Straps sliding off shoulders indicate either a band that's too loose or shoulders that are narrower than the bra's strap placement design. Try sizing down in the band, or look for brands offering straps that are closer to the neck or that can be customized.

When the center gore doesn't lie flat against your sternum, this typically means your cup size is too large or your band is too loose. Try decreasing the cup size by one letter or sizing down the band. A flat center gore indicates proper fit.

While the EU system is standard throughout most of Europe, some countries use slight variations. France, Belgium, and Spain historically used slightly different notations for the same measurements. Modern standardization has largely unified the system, but you may encounter vintage sizing from these regions.

French sizing historically used 75, 80, 85, 90, 95, 100, 105 for band sizes (the same as EU system). Germany, Italy, and Scandinavia have adopted EU standardization. When shopping across European retailers, verify the sizing system listed on the product.
