Enter your body measurements
Formula and sizing approach used
This calculator converts your bust, waist, and hip measurements into centimeters. It then compares them against standardized size charts for the chosen region.
For each available size, it calculates a distance score using the formula:
score = (bust_input - bust_size)^2
+ (waist_input - waist_size)^2
+ (hips_input - hips_size)^2The size with the smallest score is selected as the recommended dress size. This least-squares approach balances differences across all three key measurements.
Real-world brands vary, so always check their specific charts and size notes.
How to use this dress size calculator
- Choose your measurement units (centimeters or inches) and preferred region such as US, UK, EU, France, Italy, Japan, or international letters.
- Select your preferred fit: regular, petite, or plus. This gives context for the size advice and style expectations.
- Measure bust, waist, and hips using a flexible tape, keeping it horizontal and comfortably snug without compressing the body.
- Enter the three measurements and click “Calculate dress size”.
- Review the recommended size, measurement conversion, and highlighted row in the example size chart for your selected region.
- Use the CSV or PDF download buttons to save the example table for future reference or to compare with brand-specific size guides.
For best results, measure over minimal clothing and ask someone to help with hard-to-reach areas like the back and hips.

Detailed dress size guidance
1. What this dress size calculator does
The calculator estimates your closest dress size by comparing bust, waist, and hip measurements with regional size charts. It focuses on overall fit balance rather than matching a single measurement perfectly.
2. Supported regions and size systems
You can convert measurements into sizes for United States, United Kingdom, Europe, Australia, France, Italy, Japan, and lettered international ranges from XXS to XXL using a single set of body measurements.
3. Measurement tips for accurate results
- Use a soft tape and stand naturally without holding your breath.
- Keep the tape parallel to the floor around bust and hips.
- Measure the narrowest part of the waist, above the navel.
- Take each measurement at least twice and average the values.
4. How bust, waist and hips interact
The calculator uses all three measurements together. A slightly larger bust with smaller hips may still point to the same size as more balanced proportions because the algorithm minimises combined squared differences.
5. Understanding regular, petite and plus fits
Fit type does not change the recommended number directly but shows whether you should look for shorter lengths, adjusted proportions, or extended size ranges. Always check brand notes for petite or plus sizing guidance.
6. Interpreting the example size chart
The example table lists sizes and their reference bust, waist, and hip measurements for the chosen region. The highlighted row indicates the size whose chart values sit closest to your converted body measurements.
7. Saving and comparing results with CSV or PDF
Use the CSV export to open your size chart in spreadsheets and compare different measurements over time. The PDF export saves a static snapshot that you can print or quickly reference while shopping or tailoring.
8. Using this tool for online shopping
Before ordering a dress, match the recommended size to the retailer chart, then consider ease, fabric stretch, and garment style. For occasion wear, many people prefer slightly more ease at hips and waist for comfortable movement.
For related planning, you can estimate project budgets with tools like the Hot Tub Installation Cost Calculator when coordinating outfits with home or event upgrades.
9. Converting between international dress sizes
Because brands apply size systems differently, use the charts here as a neutral reference. Compare your suggested size in one region with others, such as mapping a US 8 to approximate UK, EU, or international letter sizes.
10. Practical example scenarios and next steps
Example: a user with 92 cm bust, 74 cm waist, and 100 cm hips may receive a medium style recommendation in several regions. For visual planning, pairing outfits with tools such as the Lighting Angle Calculator helps design how dresses appear in photos or display spaces.
