Quick Answer

To measure your bra size, you'll need a soft measuring tape. First, measure your band size by wrapping the tape snugly around your ribcage, just under your bust. Then, measure your bust at the fullest part. Subtract the band measurement from the bust measurement to find your cup size. Remember, sizes can vary between brands, so always check the specific brand's size chart.

Finding a bra that fits perfectly can transform your comfort and confidence. Whether you're shopping for a new everyday bra or a special piece, knowing your measurements is the first step. Many women wear the wrong size without realizing it, leading to discomfort and lack of support.

In this guide, we'll walk you through how to measure yourself at home with just a measuring tape. We'll also share common mistakes to avoid and tips for choosing the right bra style for your shape.

Why Accurate Measurements Matter

A well-fitted bra provides essential support, prevents back and shoulder pain, and enhances your silhouette. When you measure correctly, you can shop online with confidence, knowing that the bras you order will fit comfortably. Ill-fitting bras can cause chafing, spillage, or straps that dig into your shoulders.

Your bra size can change due to weight fluctuations, hormonal changes, or aging. Therefore, it's recommended to measure yourself every six months or before purchasing new bras. This ensures you're always wearing the most supportive size.

What You'll Need

To measure your bra size at home, you'll need a soft, flexible measuring tape. If you don't have one, you can use a piece of string and a ruler. Wear a non-padded bra or no bra at all for the most accurate measurements. Stand straight with your arms relaxed at your sides.

Step-by-Step Measuring Process

Follow these steps to determine your band and cup size. Remember to measure in inches or centimeters consistently, and use the brand's size chart for conversion.

Steps to Measure Your Bra Size

  1. Measure Your Band Size: Wrap the measuring tape snugly around your ribcage, directly under your bust. The tape should be level and parallel to the floor. Exhale and take the measurement in inches. Round to the nearest whole number. If the number is even, add 4 inches; if odd, add 5 inches. This is your band size. Common mistake: measuring too loosely. The tape should be snug but not tight, allowing one finger to slip underneath.
  2. Measure Your Bust Size: Wrap the tape around the fullest part of your bust, keeping it level across your back. The tape should be snug but not compressing. Record this measurement in inches. Checkpoint: Ensure the tape is not dipping at the back; it should sit parallel to the floor all the way around.
  3. Calculate Your Cup Size: Subtract your band size from your bust measurement. The difference in inches determines your cup size: 0-1 inch = AA, 1-2 = A, 2-3 = B, 3-4 = C, 4-5 = D, 5-6 = DD/E, and so on. Common mistake: assuming cup size is absolute. Cup size is relative to band size; a 34C has the same cup volume as a 36B.
