The Hesapstan bra size calculator estimates band and cup size from underbust and bust measurements using a common EU/TR convention.
How is it calculated?
Underbust is rounded to the nearest 5 cm band size. The difference between bust and underbust determines the approximate cup letter.
Bra sizes differ by brand, model, fabric and cut. The result does not replace trying the item or checking the brand size chart.
Measurement example and result
If underbust is 78 cm and bust is 94 cm, the band is rounded to the nearest 5 cm step and the difference gives an approximate cup. The result follows a common EU/TR retail convention; brand charts prevail.
Cut, fabric, model, sizing system and comfort preference can change fit; this is not a medical or brand-specific determination.
The result is an arithmetic interpretation of entered values; it does not replace official action or professional review.
Outside the scope
- No live application, approval or official-record check is performed.
- The tool cannot validate the real-world correctness of wrong input values.
- Current special conditions should be confirmed with the relevant institution, bank, brand or official source.
