How It Works
How to Find Your Dress Size from Measurements
Dress size is primarily determined by three measurements — bust, waist, and hips. This calculator compares your measurements against a standard US women's dress size chart and converts to UK and EU sizes.
Step 1 — Measure yourself
Using a soft tape measure, take your bust (fullest part of chest), waist (narrowest point), and hips (fullest part). Measure in a well-fitted bra or none for the most accurate bust measurement. Stand naturally and keep the tape level.
Step 2 — Enter measurements
Select your unit (inches or cm), choose your dress type, and enter your measurements. Height and weight are optional — they add context but do not change the size estimate significantly.
Step 3 — Get your size estimate
The calculator matches your measurements to the closest standard dress size and shows your estimated US, UK, and EU size. Always compare with the specific brand's size chart before purchasing, especially for formalwear.

Special Dress Types
Wedding Dress, Prom Dress, Plus Size and Dress Shirt Sizing
Sizing varies significantly between dress types. Here is what you need to know for each category.
Wedding Dress Size Calculator
Wedding dress sizes typically run 1–2 sizes smaller than regular clothing. A woman who wears a US 8 in regular clothes may need a US 10 or 12 in bridal sizing. Most bridal consultants recommend sizing up and tailoring down for the best fit. Your bust, waist, and hips all need to fit — if they fall into different sizes on the bridal chart, size for the largest measurement and alter the rest.
Prom Dress Size Calculator
Prom dress sizing varies by designer and style. Fitted or corseted prom dresses require very precise bust, waist, and hip measurements. A-line and flowy styles are more forgiving. Most prom dress brands use US sizing with their own specific charts — always check the exact designer's size guide. Order early to allow time for alterations.
Plus Size Dress Calculator
Plus size dresses in the US typically start at size 14W or 16W, depending on the brand. Standard plus size conversions: US 14W = UK 18, US 16W = UK 20, US 18W = UK 22. Many plus size brands have their own charts that differ from standard conversions. Measure bust, waist, and hips carefully — plus size fit can vary widely between brands and styles.
Dress Shirt Size (Men's)
Men's dress shirt size is determined differently from women's dress size. Key measurements are: neck circumference (determines collar size), chest circumference, sleeve length (shoulder to wrist), and shoulder width. Common sizes run from 14.5 to 18.5 neck. For a fitted shirt, subtract 1–2 inches from chest measurement. Always check the specific brand's dress shirt size chart.
Height, Weight and Dress Size
Can You Calculate Dress Size by Height and Weight?
Height and weight alone are not reliable enough to determine dress size — but they can give useful context alongside your measurements.
Why measurements are more accurate
Two women with the same height and weight can have completely different body proportions — and therefore completely different dress sizes. One may have a larger bust and narrower hips, the other the opposite. Bust, waist, and hip measurements are far more reliable for dress size estimation than height and weight alone.
When height and weight help
Height is useful for determining petite, regular, or tall sizing. Most petite ranges are for heights under 5'4" (163cm). Tall ranges are for heights over 5'8" (173cm). Weight can help estimate general size range when measurements are unavailable, but should not replace actual body measurements for ordering dresses — especially formalwear.

What size wedding dress am I?

Use this calculator as a starting point, then check the specific bridal brand's size chart. Most bridal consultants recommend sizing up and tailoring down for the best fit.
What size prom dress am I?
Prom dress size depends on bust, waist, hips, and the specific designer's chart. Enter your measurements into this calculator for a starting estimate. Fitted prom dresses require more precise measurements than A-line or flowy styles. Order well in advance to allow time for alterations.
Can I calculate dress size by height and weight?
Height and weight alone are not reliable for dress size estimation. Two people with the same height and weight can have very different body proportions and dress sizes. Bust, waist, and hip measurements are more accurate. Height can help determine petite vs regular vs tall sizing, but should be used alongside measurements — not instead of them.
What is my dress size in US and UK?
UK dress sizes are typically 4 numbers higher than US sizes. US 8 = UK 12, US 10 = UK 14, US 12 = UK 16. EU sizes run approximately 32 numbers higher than US sizes — US 8 = EU 40. These are general conversions. Always check the specific brand's chart as sizing can vary.
How do I find my plus size dress size?
Plus size dresses in the US typically start at size 14W or 16W. Measure your bust, waist, and hips accurately and enter them into this calculator. The calculator covers sizes up to US 24 (UK 28, EU 56). For plus size formalwear, always check the specific brand's plus size chart as sizing varies widely between brands.
What is my dress shirt size?
Men's dress shirt size is determined by neck circumference and sleeve length — not women's dress sizing. Measure around your neck just below the larynx for collar size (typically 14.5 to 18.5 inches). Sleeve length is measured from the center back of the neck to the wrist. Chest and shoulder width determine the body fit. Check the specific brand's dress shirt size chart for exact sizing.
What is a petite dress size?
Petite sizing is for women under approximately 5'4" (163cm). Petite dresses have shorter overall length, shorter torso, shorter sleeves, and narrower shoulders compared to regular sizes. Petite sizing does not mean smaller — it refers to proportions for shorter frames. A petite US 12 has the same bust/waist/hips as a regular US 12 but with adjusted length proportions.
