Complete Bra Size Guide
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
Ingrese ambas medidas en la calculadora de arriba, seleccione su unidad y sistema de tamaño preferidos, luego haga clic en Calcular. Obtendrás tu talla de sujetador, tallas hermanas y tallas en los más de 17 sistemas internacionales.

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.
Ejemplo: tamaños hermanos 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.
- La banda debe quedar ajustada y nivelada alrededor de tu torso. Debería poder colocar dos dedos debajo.
- La parte central (panel frontal) debe quedar plana contra tu pecho.
- Si estás entre tallas, sube una talla de banda y baja una talla de copa (o viceversa) usando tallas hermanas.
