Measure Your Bra Size Guide

Wearing the right bra size isn’t just about comfort—it’s a transformative boost in confidence. An incorrect size can lead to slipping straps, back bulges, gaping cups, or spillage. Don’t worry, finding your perfect fit is actually very simple.

Just follow our step-by-step visual guide below. All you need is a soft measuring tape and a few minutes.

Preparation:

• Tool: A soft measuring tape.

• Attire: It’s best to be undressed or wearing a non-padded, non-push-up bra.

• Posture: Stand up straight, breathe naturally, and relax.

Step 1: Measure Your Band Size

The band is the core of support. An accurate measurement is crucial.

1.How to Measure:

• • Wrap the measuring tape horizontally around your torso, under your bust, right at the root of your breasts.

  • Ensure the tape is level all the way around your body and parallel to the floor.

  • It should be snug against your skin but not tight. You should be able to slip one finger comfortably underneath the tape.

Step 2: Measure Your Bust Size

This measurement determines your cup size. Posture is key to getting an accurate reading!

1.How to Measure:

• • Lean forward at a 45-degree angle, allowing your breasts to fall naturally forward. This measures the fullest part of your bust. (We strongly recommend an illustration here showing this posture!)

  • Wrap the measuring tape horizontally around the fullest part of your breasts (typically across the nipples).

  • Again, ensure the tape is parallel to the floor and goes around your body smoothly. The tape should not compress your breasts, but it shouldn’t be loose either.

2.Read the Number:

• • Read the value on the tape and record it (again, in centimeters or inches).

Expert Advice: For those with very soft breast tissue or significant sagging, try measuring in three positions—standing straight, leaning forward 45°, and lying on your back—then take the average. This often yields a more accurate cup size.

Step 3: Calculate Your Perfect Size

Now you have the two key numbers. Time for some simple math.

1.Calculate the Cup Difference:

• • Bust Measurement – Band Measurement = Cup Difference

2.Determine Your Size:

• • Take the Band Measurement you got in Step 1 (e.g., 78 cm).

  • Take the Cup Difference you calculated in Step 3 (e.g., 13 cm).

  • Take these two numbers and consult our website’s [Perfect Bra Size Chart].

  • Find the corresponding band and cup in the chart. Their combination (e.g., 80B) is your ideal starting size!

The Fit Check: Confirming Theory with Practice

Because fits vary between brands and styles, your measured size is the best starting point, but trying it on is the ultimate test.

During the fit check, look for the following:

• The Band:

  • The band should lie parallel to the floor, front and back at the same height.

  • It should be snug enough to provide support but not dig in. You should be able to comfortably slide one or two fingers underneath it.

• The Cups:

  • Perfect Enclosure: Your breast tissue completely fills the cups without any “spillage” (cup too small) or “gaping” (cup too large).

  • The Gore: The center front (gore) between the cups should lie flat against your breastbone.

• The Straps:

  • Adjust them so you can only easily slide one finger underneath. They are for fine-tuning and slight lift, not primary support.

Common Questions & Myths

• Myth #1: “If the band feels tight, I should go up a band size.”

  • Truth: Often, a tight band is actually caused by cups that are too small! When cups can’t fully encompass your breast tissue, it pushes the whole bra away from your body, making the band feel tight. Try going up one cup size while keeping the same band size—you might find the band suddenly feels just right.

• Myth #2: “I always wear the same size.”

  • Truth: Your body changes, and sizing standards differ between brands. We recommend remastering your size every 6-12 months and always checking the specific size chart when buying from a new brand or trying a new style.
