Learn to measure your bra size at home with our step-by-step guide. Get tips for accurate measurements and find your perfect fit.
Quick Answer
To measure your bra size at home, you'll need a soft measuring tape. Measure your underbust and bust, then calculate your band and cup size using a simple formula. For the most accurate results, measure while wearing a non-padded bra and have someone help if possible.
Finding a perfectly fitting bra can transform how your clothes look and how you feel. Yet many of us wear the wrong size without realizing it. The good news is that you can measure your bra size at home with just a tape measure and a few minutes.
In this guide, we'll walk you through the steps to measure yourself accurately, explain how to interpret the numbers, and share tips for choosing bras that fit well. Whether you're shopping for a new everyday bra or a special occasion piece, knowing your measurements is the first step.
Why Measuring at Home Matters
A well-fitted bra provides support, comfort, and a smooth silhouette. But bra sizes can vary between brands and styles, so relying on a single number isn't enough. Measuring at home gives you a baseline to start from, but you should always try on bras and adjust based on how they feel.
Many women wear bras that are too loose in the band or too small in the cup, leading to discomfort and poor support. By learning to measure correctly, you can narrow down your size and make shopping easier, whether online or in-store.
What You'll Need
Gather a soft measuring tape (the kind used for sewing), a mirror, and ideally a non-padded bra to wear during measurement. If you don't have a tape measure, you can use a piece of string and a ruler, but a flexible tape is easiest.
For the most accurate results, measure yourself when your breasts are at their usual size—avoid measuring during your period if you experience swelling. Also, try to have a friend help you if possible, as it can be tricky to hold the tape perfectly horizontal on your own.
Step-by-Step Guide to Measuring Your Bra Size
- Measure your band size: Wrap the measuring tape snugly around your ribcage, directly under your bust. Keep the tape 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 gives you your band size. Common mistake: measuring too loosely. The tape should be firm but not tight.
- Measure your bust size: Wrap the tape around the fullest part of your bust, keeping it level across your back. Ensure the tape is not too tight or too loose. Take the measurement in inches and round to the nearest whole number. Checkpoint: The tape should sit comfortably without digging in or sliding down.
- Calculate your cup size: Subtract your band size from your bust measurement. The difference in inches corresponds to your cup size: 1 inch = A, 2 inches = B, 3 inches = C, 4 inches = D, 5 inches = DD, and so on. Common mistake: using the wrong band size can throw off cup calculation. Double-check your band measurement.
- Try on and adjust: Use your calculated size as a starting point. When trying on bras, check that the band sits horizontally and doesn't ride up, the center gore lies flat against your sternum, and the cups fully contain your breasts without spillage or gaps. Adjust straps so they are snug but not digging in. Checkpoint: The band should provide about 80% of the support. If the band rides up, go down a band size.
