Finding the perfect bra size can significantly impact comfort, support, and overall well-being. In India, bra sizing primarily relies on two key measurements: the band size (underbust) and the cup size, which is derived from the difference between the bust measurement and the band measurement. This calculator simplifies that process, providing a recommended Indian bra size based on your measurements.
How to Measure for Your Bra Size:
Band Measurement (Underbust): While wearing a non-padded, non-minimiser bra, wrap a soft measuring tape snugly around your ribcage, directly under your bust. Ensure the tape is level all the way around and fairly tight – it should feel snug. Take the measurement in centimeters (cm). This is your band size.
Bust Measurement (Fullest Part): Loosely wrap the measuring tape around the fullest part of your bust (nipples). Keep the tape parallel to the ground. Ensure the tape is not too tight, and that you are standing naturally. Take the measurement in centimeters (cm).
Calculating Your Cup Size:
The cup size is determined by the difference between your bust measurement and your band measurement. The general formula for Indian bra sizing (which closely aligns with international standards) is:
Difference (Bust – Band)
0-1 cm: AA Cup
1-2 cm: A Cup
2-3 cm: B Cup
3-4 cm: C Cup
4-5 cm: D Cup
5-6 cm: DD Cup (sometimes E Cup)
6-7 cm: DDD Cup (sometimes F Cup)
7-8 cm: G Cup
…and so on, with approximately 1-inch (2.5 cm) difference per subsequent cup size.
Note: Bra manufacturers can have slight variations in their sizing. This calculator provides a strong starting point, but trying on the bra is always the best way to confirm the perfect fit.
Adjusting for Band Fit Preference:
Different people prefer different levels of tightness in their bra band.
Snug (Tighter) Fit: If you prefer a tighter band, you might find a smaller band size fits better.
Standard Fit: This is the most common preference and what the calculator primarily aims for.
Loose (Comfier) Fit: If you like a looser band, you might need a larger band size.
Our calculator incorporates this preference by slightly adjusting the band size calculation. A snug preference might shift you to a smaller band, and a loose preference to a larger band, while standard aims for the direct measurement.

This calculator is intended as a guide only. Bra sizing can be influenced by brand, style, and individual body shape. For the most accurate fit, we recommend consulting with a professional fitter or trying on bras from different brands.

// For this calculator, let's just state the standard calculation and advise trying smaller.
// A more complex logic could map band ranges to specific Indian sizes (e.g., 75, 80, 85)
// and then suggest a smaller standard size.

// We will indicate the preference in the result.
