No question has plagued women’s fashion quite like “how to find your cup size at home.” Especially in recent years, when popping into the local lingerie store is more difficult, women have been turning more to at-home solutions and answers for new bras.

Whether you’re shopping for a treat for yourself or to surprise a special someone, getting the right size bra is key. Here’s a step-by-step guide to finding your perfect bra.

A Brief Explanation of Cups and Bands

You might be familiar with this, but just in case, here’s a brief rundown of cups and bands. It will help you learn how to find your bra size at home:

  • Bands: The piece of material that holds the cups together and wraps around your back. This is the number portion of a bra size.
  • Cups: This refers to the fabric that holds your breasts and gives you support. This is the letter of a bra size.

Your cup measurement is the difference between the largest part of your bust and your band size (more on how to find your cup size at home later).

Cup and band sizes will vary from manufacturer to manufacturer but here’s how to measure to get a baseline. You’ll need a soft measuring tape (the kind for clothing) and a pen and paper to record your measurements.

How to Find Your Bra Size at Home

Measure for Your Band Size

Start completely topless to ensure your breasts are in their most natural shape and position. Using the tape measure, wrap it around your rib cage, just beneath your bust. The tape should be parallel to the floor and you should be able to fit a finger underneath it.

Round this measurement to the nearest whole number and that’s your band size. If you’re heavier chested, round down for a slightly more snug fit for more support. If you’re smaller chested, round up for a bit more comfort on your rib cage.

Part of how to find your bra size at home is to consult the manufacturer’s sizing. Some brands will have you add four if your band size is even or add five if your band size is odd. For example, if your measurement was 34, your band size would be 38. Or, if your measurement was 29, your band size would be 36.

No one is really sure where this industry-standard came from, and some brands don’t use it. Check your manufacturer’s sizing to see if you need this addition.

How to Find Your Cup Size at Home

The next step in how to find your bra size at home is measuring for your cups. With the tape measure again parallel to the ground, measure around your chest at nipple height (or the fullest part of your breasts).

Now, take your bust measurement and subtract your band measurement. This number is your cup size. If your bust and band are the same, you’re an AA cup. If there’s a 1-inch difference, you’re an A cup, a 2-inch difference is a B cup, and so on.

One of the most important parts of learning how to find your bra size at home is to not get attached to any set of numbers. Bodies change over time and so do manufacturer’s guidelines. Check your measurements often for best-continued results.
