Dress Size Calculator
Measurements of 34.5-26.5-36.5 inches put you at a US size 6, which is a UK 10 and an EU 38. This dress size calculator matches your bust, waist, and hip measurements against the standard US misses chart and converts to UK and EU sizing. When your three measurements straddle two sizes, it weights the bust most heavily, the way fit advice usually goes, and dresses are easier to take in than let out.
Quick answer
Dress sizes map three measurements, bust, waist, and hips, to a single number.
Dress size
US 6 (UK 10, EU 38)
Closest chart fit
bust 34.5", waist 26.5", hips 36.5"
What this tells you
- •Dress sizes map three measurements, bust, waist, and hips, to a single number.
- •The calculator finds the chart size closest to all three, weighting bust highest.
- •UK sizes run 4 higher than US (US 6 = UK 10), and EU sizes add 32 (US 6 = EU 38).
- •Vanity sizing means brands drift a size or more from the standard chart, so treat the result as a starting point.
How to Use
- 1Measure your bust at the fullest point, wearing a non-padded bra.
- 2Measure your natural waist at the narrowest point, usually just above the navel.
- 3Measure your hips at the widest point, about 8 inches below the waist.
- 4Enter all three in inches or centimeters and read your US, UK, and EU sizes.
How It Works
Formula
size = closest chart row by weighted bust, waist, and hip matchThe US misses chart steps roughly an inch per size through size 10, then 1.5 inches per size beyond. The calculator scores each chart row by how far your measurements sit from it, counting bust double, and returns the closest size. A 35-27-37 figure scores closest to size 6 even though the waist leans toward 8, because bust fit is hardest to alter.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
Classic size 6 measurements
All three measurements sit exactly on the size 6 chart row.
Metric measurements
92-76-101 cm converts to about 36-30-40 inches, closest to the size 10 row.
Between sizes
The bust sits between 6 and 8 but the waist and hips both lean 8, so 8 wins.

How to use a size estimate when shopping
Measure with a flexible tape over the undergarments or thin layers you expect to wear. Keep the tape level around the body and snug enough to stay in place without pressing into the skin. A mirror or another person can help catch a tape that rises at the back. Record the numbers instead of relying on a size already in your closet.
The calculator compares your three measurements with one US misses chart. It doubles the bust difference in the score, then adds the waist and hip differences. The row with the lowest total becomes the result. This is a mathematical closest match, not a claim that every part of that size will fit. A person whose measurements differ from the chart's proportions may have two nearby scores with different tradeoffs.
Check the retailer's garment chart before ordering. Some charts describe body measurements, while others list finished garment measurements. Finished measurements include design ease, which varies between a fitted sheath dress and a loose knit style. Fabric stretch, lining, seam placement, neckline, sleeve shape, and intended silhouette can change which size feels comfortable.
When measurements fall across sizes, focus on the part of the garment that is hardest to alter and the fit you prefer. A structured dress may need enough room at the bust or hips. A stretchy or loose design may be more forgiving. Customer reviews can reveal whether a particular item runs small or large, but your measurements and the item's own chart remain the better comparison.
US, UK, and EU conversions are convenient labels rather than a universal standard. Retailers sometimes use different numbering systems for misses, juniors, petites, tall ranges, and plus sizes. Some European brands label by country rather than a single EU scale. Confirm the chart shown on the product page, especially for formalwear or an item that will be expensive to return or alter.
A clothing size is only an inventory label. It does not measure health, fitness, attractiveness, or personal worth. Bodies and garments both vary. If a suggested size does not fit, the useful conclusion is that the chart or cut does not match your measurements, not that anything is wrong with your body.
Common mistakes
- Measuring over bulky clothes. Measure over underwear or thin clothing with the tape snug but not compressing.
- Using your jeans waist for the natural waist. Jeans sit lower, often 2 to 4 inches bigger than the natural waistline the chart uses.
- Assuming your size is identical in every brand. Vanity sizing shifts charts by a size or more, so check each brand's own chart for big purchases.
- Sizing to the smallest measurement. Fit the largest one, usually bust or hips, since taking in is easier than letting out.
- Pulling the tape tight enough to compress the body or letting it droop at the back.
- Using an old measurement after a change in underwear, posture, or body measurements.
- Assuming the simple US-to-UK or EU conversion matches every retailer's labels.
