About us

My Dress Size Calculator was built out of a simple frustration: clothing sizes aren't standardized, and figuring out what size to buy online often means guessing, ordering multiple sizes, or digging through a dozen different brand size charts. We wanted a single, fast, free tool that turns a few body measurements into a clear answer, without ads getting in the way, without an account, and without your measurements ever leaving your device.

What we built

The calculator matches your bust, waist and hip measurements against commonly used women's size-chart standards and instantly returns your estimated size across US, UK, EU, AU and International sizing , along with a fit-preference adjustment and an estimated body shape. Everything runs directly in your browser using JavaScript; there's no server processing your measurements and nothing is stored.

Independent and unaffiliated

My Dress Size Calculator is an independent project and is not affiliated with, endorsed by, or connected to any specific clothing brand or retailer. Our size charts are based on widely published industry averages, intended as a helpful estimate rather than an official brand measurement.
