How to Use the Cup Size Calculator

Using the Cup Size Calculator is easy and involves a few simple steps to accurately determine your correct bra size. This guide will walk you through the process of inputting your measurements, selecting the appropriate sizing system, and understanding the results.

Step 1: Enter Your Measurements

  • Underbust Measurement: Measure around your ribcage directly under your bust. Enter this measurement in inches into the “Underbust Measurement” field. Note that valid measurements range from 20 to 60 inches, and you should enter increments of 0.5 inches.
  • Bust Measurement: Measure around the fullest part of your bust, ensuring the tape is level. Enter this measurement into the “Bust Measurement” field. Valid measurements for this field range from 20 to 70 inches, also in increments of 0.5 inches.

Step 2: Select Your Country’s Sizing System

Choose the sizing system that applies to your country from the “Country Sizing System” dropdown menu. You can select from the following options:

  • US/UK
  • EU
  • France
  • Australia/NZ

This selection is essential as bra sizes can vary based on regional standards.

Step 3: Calculate Your Results

Once you have entered your measurements and selected your sizing system, the calculator will automatically compute your results. Here’s what you will receive:

  • Band Size: This is calculated by rounding your underbust measurement to the nearest even number.
  • Difference (inches): This value is the difference between your bust and underbust measurements.
  • Cup Size: Based on the difference calculated, your cup size is determined. It ranges from ‘AA’ to ‘L+’, depending on the measurement difference.
  • Full Bra Size: The calculator combines your band size and cup size to provide a complete bra size, indicated as “Size: (Band Size)(Cup Size)”.

Understanding Your Calculations

The calculated bra size will help guide your selection when shopping for bras, ensuring better fit and comfort. If your size varies drastically from what you typically wear, consider retaking your measurements or consulting with a fitting expert.

By using this Cup Size Calculator, you can take a significant step towards finding bras that fit well and provide the proper support.
