How to Measure Your Bra Size at Home
Your bra size consists of two parts: the band size (a number) and the cup size (a letter). The band size is your underbust measurement rounded to the nearest even number. The cup size is determined by the difference between your bust and band measurements. Getting accurate measurements is the first step to finding a comfortable, well-fitting bra.
Bra Size = Band Size (number) + Cup Size (letter)
Step-by-Step Measurement Instructions
1. Measure Your Underbust (Ribcage)
Wrap a measuring tape snugly around your ribcage, directly under your bust. Keep the tape level and parallel to the ground. This measurement determines your band size.
2. Measure Your Bust (Fullest Point)
Wrap the tape around the fullest part of your bust, typically at nipple level. Keep the tape level and not too tight. Wear a non-padded bra for the most accurate measurement.
3. Enter Measurements & Calculate
Insira ambas as medidas na calculadora acima, selecione sua unidade e sistema de dimensionamento preferidos e clique em Calcular. Você obterá o tamanho do seu sutiã, tamanhos de irmãs e tamanhos em todos os mais de 17 sistemas internacionais.

What Are Sister Sizes?
Sister sizes are bra sizes that share the same cup volume but have different band and cup letter combinations. For example, 34C, 32D, and 36B are all sister sizes — they hold the same amount of breast tissue but distribute support differently.
Exemplo: tamanhos irmãos de 34C
Bra Fitting Tips
- Wear a non-padded, well-fitting bra when measuring for the most accurate results.
- Sizes can vary between brands. Always try on when possible, and consider sister sizes.
- A faixa deve ficar justa e nivelada ao redor do tronco. Você deve conseguir colocar dois dedos embaixo dele.
- O sangue central (painel frontal) deve ficar encostado em seu peito.
- Se você estiver entre tamanhos, aumente o tamanho da faixa e diminua o tamanho do copo (ou vice-versa) usando tamanhos irmãos.
