Jacket Size Calculator Based on Height and Weight
Finding the perfect jacket size can be challenging when shopping online or without trying on. Our jacket size calculator uses your height and weight to recommend the most suitable jacket size across different international sizing systems. This tool helps you make informed decisions whether you’re shopping for blazers, coats, or casual jackets.

How to Measure Your Body for Accurate Jacket Sizing
Getting accurate measurements is crucial for finding the perfect jacket fit. Here’s how to measure yourself properly:
- Chest Measurement: Wrap the measuring tape around the fullest part of your chest, just under your armpits. Keep the tape parallel to the ground.
- Shoulder Width: Measure from the edge of one shoulder to the other across your back.
- Sleeve Length: Measure from your shoulder point down to your wrist bone.
- Body Length: Measure from the base of your neck down to where you want the jacket to end.
- Waist Circumference: Measure around your natural waistline, usually just above your hip bones.
For best results, have someone help you take measurements. Wear thin, well-fitting clothes during measurement. Don’t pull the tape too tight or leave it too loose.

Our jacket size calculator takes into account the relationship between height and weight to determine your body build. This approach is more accurate than using just one measurement. The tool considers whether you have a slim, regular, or broader build to recommend the most appropriate size.
Keep in mind that jacket fit preferences vary by style and purpose. Business jackets typically fit closer to the body, while casual jackets might be looser. Consider the jacket’s intended use when choosing your final size.
Different materials also affect fit. Leather jackets often require a snugger fit initially as they stretch with wear. Cotton and synthetic blends maintain their shape better but may not accommodate significant size changes.
When shopping online, always check the brand’s specific size chart. Our calculator provides a excellent starting point, but manufacturer specifications should be your final reference. Many online retailers offer detailed measurements for each size.
If you’re between sizes, consider the jacket’s purpose and your personal style preference. Size up for layering over thick clothing or for a relaxed fit. Size down if you prefer a more tailored appearance or won’t be wearing heavy layers underneath.
