Did you know that an estimated 80% of women are wearing the wrong bra size? Dealing with straps that dig in, cups that gape, or a band that rides up your back? The root cause is almost always an incorrect measurement. In this guide, we’ll show you exactly how to measure bra size at home for a perfect, seamless fit.
The Preparation: What You’ll Need
- A Soft Measuring Tape: The fabric kind used for sewing.
- A Full-Length Mirror: To ensure the tape is level around your back.
- Your "Best Fitting" Bra: Wear a non-padded, wire-free bra to get your natural baseline.
Step 1: Measuring Your Band Size
Stand straight and exhale. Wrap the tape measure around your ribcage, directly under your bust. Ensure the tape is snug—firm but buttery soft against your skin.
Calculating the Number: If the number is even, that’s your size. If it’s odd, round up to the nearest even number (e.g., 33" becomes a 34 band).
Step 2: Measuring Your Cup Size
Wrap the tape loosely around the fullest part of your bust (usually at the nipple line). Subtract your calculated Band Size from this measurement:
- 1-inch difference: A Cup
- 2-inch difference: B Cup
- 3-inch difference: C Cup
- 4-inch difference: D Cup
- 5-inch difference: DD / E Cup

Your Fit Questions, Answered
Can I use a string if I don't have a measuring tape?
Yes. Wrap a non-stretchy string around yourself, mark the lengths, and then measure the string against a ruler. However, for a perfect fit, a soft tape is highly recommended.
What if I'm between sizes?
In our Full-Coverage Jelly Bra, we recommend sizing up if you are between cup sizes to ensure zero spilling and maximum all-day comfort.
