How to Measure Your Bra Size Accurately

Getting the right bra size is essential for comfort and support. Follow these steps for accurate measurements:

  1. Wear a non-padded bra or no bra for most accurate results
  2. Use a soft measuring tape
  3. Measure your underbust snugly where the bra band would sit
  4. Measure your overbust at the fullest part of your bust
  5. Stand straight with arms at your sides when measuring

Why UK Bra Sizing?

UK bra sizing is considered one of the most precise systems, with consistent cup sizing across brands. Unlike other systems, UK sizing uses double letters (DD, FF, GG) for larger cup sizes, allowing for more accurate fittings.

Bra Size Calculator UK – Find Your Perfect Fit

Finding the right bra size is essential for comfort, support, and confidence. With our Bra Size Calculator UK, you can easily determine your accurate bra size from the comfort of your home. Whether you’re shopping online or simply checking your current size, this tool is designed to help UK women get the perfect fit every time.

How the Bra Size Calculator Works

Our calculator uses the UK sizing system, which includes your band size (measured around your ribcage) and bust size (measured around the fullest part of your chest). Just follow these two easy steps:

  1. Measure Underbust (Band Size) – Wrap a tape measure snugly around your ribcage, just under your bust.

  2. Measure Overbust (Bust Size) – Measure around the fullest part of your chest, keeping the tape measure straight and relaxed.

Enter these two measurements into the calculator, and it will instantly tell you your UK bra size (e.g., 34C, 36DD, etc.).
