How to Measure Bra Size at Home Like a Pro

Why Proper Measurement Matters

An estimated 80% of women wear the wrong bra size, leading to discomfort and poor support. Learning to measure yourself correctly can transform how your bras fit and feel. This guide will walk you through professional measurement techniques you can do at home.

What You'll Need

  • Soft measuring tape
  • Your best-fitting non-padded bra
  • Mirror (optional but helpful)
  • Paper and pen to record measurements

Step-by-Step Measurement Guide

Measuring Your Band Size

  1. Stand straight without puffing out your chest
  2. Measure snugly under your bust where the band sits
  3. Ensure the tape is parallel to the floor
  4. If the number is even, add 4 inches; if odd, add 5
  5. This is your band size (e.g., 32, 34, 36)

Measuring Your Bust Size

  1. Wear your best-fitting non-padded bra
  2. Measure around the fullest part of your bust
  3. Keep the tape slightly loose - don't compress breasts
  4. Ensure tape is parallel to the floor
  5. Record this number

Calculating Your Cup Size

  1. Subtract band size from bust measurement
  2. Each inch difference represents a cup size:
    • 0" = AA
    • 1" = A
    • 2" = B
    • 3" = C
    • 4" = D
    • 5" = DD/E
    • And so on...

Common Measurement Mistakes

  • Measuring over clothes - creates inaccurate numbers
  • Pulling tape too tight - leads to wrong band size
  • Measuring at an angle - causes cup size errors
  • Not updating measurements - body changes over time

Signs Your Measurements Might Be Wrong

  • Band rides up in back
  • Cups gap or overflow
  • Straps dig into shoulders
  • Underwire pokes underarms
  • Discomfort after few hours of wear

When to Get Professionally Fitted

  • If you're between sizes
  • After significant weight change
  • If you have asymmetry
  • When shopping a new brand
  • Post-pregnancy or breastfeeding
