How to Measure for a Corset
Essential Measurements
Accurate measurements are crucial for finding the perfect corset. Follow these steps for the most precise results:
- Overbust: Measure around the fullest part of your bust, keeping the tape parallel to the ground.
- Underbust: Measure directly under your bust line where the bra band sits.
- Natural Waist: Measure at the smallest part of your waist, typically above your belly button. Keep the measuring tape snug but not tight.
- Hips: Measure around the widest part of your hips, usually 7-9 inches below your waist.
Pro Tip: Always measure over thin clothing or undergarments you’ll wear with the corset. Have someone help you for more accurate measurements.

Understanding Waist Reduction
Waist reduction refers to how many inches smaller your corset should be compared to your natural waist. Beginners typically start with 2-4 inches of reduction, while experienced wearers may go up to 6-7 inches. The calculator automatically factors in the recommended reduction based on your experience level.
International Sizing Conversion
Our calculator provides size conversions for different regions including US, UK, European, and Asian sizing systems. This feature is particularly helpful when shopping from international corset makers or brands that use different sizing standards.
Fit Considerations
A properly fitted corset should feel snug but comfortable when laced. Quality corsets should be worn with a 1-2 inch gap at the back for proper spine alignment and comfort. The calculator accounts for this gap in its recommendations.
Important Sizing Notes
- Always prioritize your largest measurement when between sizes
- Consider the corset’s intended use – fashion vs. waist training vs. medical support
- Different brands may have slight variations in sizing
- Quality corsets offer adjustability through lacing and sometimes hook-and-eye closures
- When in doubt, consult the specific brand’s size chart alongside these general guidelines
Types of Corsets and Sizing Differences
Different corset styles have unique sizing considerations that affect the final fit and comfort:
Underbust Corsets
These corsets sit below the bust line and focus primarily on waist shaping. Sizing is based mainly on waist measurement with hip consideration for longer styles.
Overbust Corsets
Full-coverage corsets that include bust support require both bust and waist measurements for proper fit. The bust measurement ensures adequate coverage without spillage.
Waist Trainers
Designed for regular wear and gradual waist reduction. These often have less dramatic reduction but prioritize comfort for extended wear periods.
Fashion Corsets
Made for occasional wear and aesthetic appeal. These typically allow for more comfortable sizing with moderate waist reduction.
