Editorial Policy – Our Commitment to Accuracy & Transparency
At IMRango, trust is our foundation. Every calculator, guide, and piece of content on this site is built on a commitment to accuracy, transparency, and independence.
We believe that when it comes to finding the right bra size, you deserve clear, honest information – not marketing fluff or hidden agendas. This editorial policy explains how we create, review, and update our content.
📏 Our Sizing Methodology
Every calculator on IMRango uses a clearly disclosed method:
| Method | Description | Used In |
|---|---|---|
| Standard Band & Bust | The industry-standard formula: underbust rounded to nearest even +4/+5 for band, bust difference for cup. | Bra Size, Cup Size, Band Size, Bust Size Calculators |
| ABTF (6-Measurement) | The community-developed “A Bra That Fits” method using loose, snug, and tight underbust plus standing, leaning, and lying bust. | ABTF Calculator |
| Sister Size Logic | Standard sister size mapping (band ±2, cup ∓1) for equivalent cup volume. | Sister Size Calculator |
| Brand Conversions | Brand-specific mappings based on official size charts from Victoria’s Secret, Wacoal, ThirdLove, M&S, and Skims. | Brand Size Converter |
| Volume Estimation | Research-based volume tables mapping band and cup to approximate breast volume in cc/ml. | Breast Volume Calculator |
All formulas are open and documented – we don’t hide how we calculate your size.
