自宅で正確なブラサイズを計算する方法
This tool assists in identifying the appropriate bra size, which is crucial for comfort and support. Accurate measurements are fundamental to the calculation, ensuring the resulting size provides optimal fit. The process involves precise measurement of the rib cage directly under the bust and the fullest part of the bust.
A bra size calculator determines an individual's bra measurements based on two primary inputs: the underbust (band) measurement and the overbust (bust) measurement. It applies a standardized formula to calculate the band size and then derives the cup size by finding the difference between the bust and band measurements, converting this difference into a corresponding cup letter.

This tool assists in identifying the appropriate bra size, which is crucial for comfort and support. Accurate measurements are fundamental to the calculation, ensuring the resulting size provides optimal fit. The process involves precise measurement of the rib cage directly under the bust and the fullest part of the bust.
Variables: Underbust Measurement: The circumference of the rib cage directly under the bust. Bust Measurement: The circumference around the fullest part of the bust.
Worked Example: Measure underbust at 30.5 inches, then round up to 32 inches for band size. Then measure bust at 36 inches. Then subtract band from bust: 36 - 32 = 4 inches. Then convert 4 inches to a D cup, resulting in a 32D bra size.
The methodology for bra sizing is based on established industry standards for converting body measurements into apparel sizes. While no single regulatory body dictates bra sizing, the principles align with anthropometric data collection practices for garment construction. This calculator applies common sizing conventions used by manufacturers.

How Bra Size Calculation Works - Medical Methodology
Our Bra Size Calculation System uses international fitting standards to provide accurate sizing assessments and health-focused recommendations. Here's the complete technical methodology:
Core Fitting Formula: Band Size = Underbust measurement (rounded to nearest even number). Cup Size = Bust measurement - Band measurement difference converted to international cup standards.
International Conversions: Automatic conversion between US, UK, EU, and FR sizing systems using standardized conversion tables recognized by international lingerie associations.
Sister Sizing: Calculated using volume equivalence principles - when band size increases by 2, cup size decreases by one letter to maintain similar cup volume.
Specialized Bra Types: Sports bras typically fit tighter in band, nursing bras accommodate breast changes, maternity bras provide extra support during pregnancy.
AI Accuracy Enhancement: Our algorithms incorporate fitting research data across different body types and health conditions to provide context-aware bra recommendations.
Bra Fitting Management Strategies
- Measure regularly - bra size can change with weight fluctuations, hormonal changes, and aging
- Consider sister sizes - different brands may fit better in alternative sizes with similar cup volume
- Focus on comfort and support - proper fitting prevents back pain and improves posture
- Try before buying - sizes can vary between brands and styles even with accurate measurements
- Consult professional fitters - for persistent fitting issues or specialized needs, seek expert advice
