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

Voer beide metingen in de rekenmachine hierboven in, selecteer de gewenste eenheid en het maatsysteem en klik vervolgens op Berekenen. Je krijgt je bh-maat, zustermaten en maten in alle 17+ internationale systemen.

FR (France) Sizing

Maakt gebruik van op centimeters gebaseerde bandgroottes (voeg 15 toe aan de VS/VK-band). Bekers hetzelfde als EU. Voorbeeld: US 34C = FR 49C.

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.

Voorbeeld: Zusmaat 34C

32D 33C½ 34C 35B½ 36B

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.
  • De band moet strak en vlak rond uw romp zitten. Er zouden twee vingers onder moeten kunnen.
  • Het middelste deel (voorpaneel) moet plat tegen je borst liggen.
  • Als je tussen twee maten in zit, ga dan een omtrekmaat groter en een cupmaat kleiner (of andersom) met zustermaten.
