Let’s find your Bra Size Starting Points!

This guide will show you a simple way to calculate your bra size starting points. I say “starting points” because your bust and underbust measurements will give you an approximate idea of your current bra size. Numbers are information, not a definition. And because every bra fits differently, women’s bodies fluctuate, and brands size their bras using various methods, there is no one standard or scientific way to calculate your exact bra size.

My hope is that by measuring yourself and calculating your bra size starting points, you’ll be one step closer to saying hurray! Use these starting points to make an informed purchase online, to choose bras to try on at your local shop, or even to stay in the know when working with a bra fitter.

After using the simple guide below, I’ve shared a few of my favorite resources for you to use these bra size starting points. From a guide on how to tell if your bra fits, to learning how bra sizing works across the globe. PS: Check out the More Than My Numbers project to see what bra sizes other women wear!
