Bra calculator

A bra calculator can be used to help determine bra size. The big caveat is that most bra calculators are absolute garbage; they're so bad as to be completely useless.

How to tell if a calculator is inaccurate

Signs of a bad bra calculator include:

• If it tells you to measure your "overbust", or under your armpits
• If, in UK and US calculators, the band size is several numbers larger that the number you put as your ribcage or underbust measurement (ex: Your ribcage measures 38 but the calculator tells you to wear a 42)
• If, in EU/JP calculators, it says the number you measured your ribcage as is the same as your band size (ex: your ribcage measures 65cm, and the calculator says to wear a 65). The EU/JP sizing system has "plus four" built into it

Bra fit calculators

There are a few fit calculators that yield accurate results.

• SizemApp Bra Size Calculator using 6 sets of different measurements, most accurate
• "Bra Calculator", the most commonly used calculator from A Sophisticated Pair (use "very snug" setting)
• "Bra Size Calculator", a calculator from Butterfly Collection Lingerie
• "ABTF Bra Size Calculator", created by an A Bra That Fits user
