Sizing varies by brand — use this as a starting point and try on a few sizes for best fit.
Accurate Bra Size Calculator and Free Digital Tools on ToolPilotHub
Finding the measurements should not be a guess. It should not involve confusion or the need to pay for a fitting. ToolPilotHub gives you web-based tools that make daily calculations and tasks simple. We connect measurement systems with everyday use. Our tools are fast, smart and work directly in your browser.
At the heart of our tools is the Bra Size Calculator. It is built to help people avoid sizing errors that happen when different brands use standards. This tool helps you find a fit that's both accurate and comfortable. Alongside the Bra Size Calculator, ToolPilotHub offers other tools. They are made for use and professional tasks.
Sizing conventions vary somewhat between brands and countries, so this gives a standard US-convention starting point — trying on a few sizes is still the most reliable way to find your best fit, since brand cut and material affect actual fit meaningfully.

Discover Our Bra Size Calculator
Wearing the wrong size can cause back pain, bad posture and daily discomfort. That is why we made the Bra Size Calculator. It uses math to give you a size, all from your home.
How the Fit Alignment System Works
Different brands measure differently. That makes shopping frustrating. Our calculator solves this. It uses two measurements: your underbust and your overbust. Then it uses math to find your correct band size and cup shape.
Tips for Getting the Most Accurate Measurement
To get the best results, measure carefully. Follow these steps before using the tool.
• Use a Flexible Tape Measure: Keep it flat. Level around your body. Do not pull it tight. Let it sag.
• Measure Without Padding: Wear no padding. Use a -wired bra or go bare. This gives a body shape.
• Exhale: Take your underbust measurement after a natural breath out. This ensures comfort all day.
