Use a soft measuring tape and measure directly against your body — do not measure over thick clothing. For bust, wrap the tape around the fullest part of your chest. For waist, find the narrowest point of your torso (typically just above the belly button). For hips, measure around the widest part of your hips and buttocks. Ask a friend to help for more accurate results. See also our Fabric Calculator.
Take your bust, waist, and hip measurements in centimeters or inches. Match those measurements to a standard dress size chart to find the best fit. When measurements fall between two sizes, always size up to ensure comfort. This calculator does that matching automatically across US, UK, EU, and International sizing.
A EU size 38 typically corresponds to a US size 8 and a UK size 12. It generally fits a bust of around 86–89 cm (34–35 in), a waist of around 69–72 cm (27–28 in), and hips of approximately 92–95 cm (36–37.5 in).
A UK size 12 is generally considered a Medium (M) in international sizing. It corresponds to a US size 8 and an EU size 38. Keep in mind that size labeling varies slightly between brands, so always check the brand's own size guide when possible. You might also find our calculate Total Fabric Width Needed, Total Fabric Height Needed & Total Fabric Width (cm) — Cross-Stitch useful.
A US size 14 corresponds to a UK size 18 and an EU size 44. It typically fits a bust of about 102–105 cm (40–41.5 in), a waist of around 84–88 cm (33–34.5 in), and hips of approximately 107–111 cm (42–43.5 in). It falls in the plus-size range for many international brands.
Standard size charts work well for most dress styles, but fit can still vary depending on the garment's cut, fabric, and the designer's own grading. Bodycon styles require a closer fit while shift or A-line dresses may have more flexibility. Always compare your measurements against the specific brand's chart before purchasing.
When your measurements fall between two sizes, it's generally recommended to choose the larger size and tailor for a better fit if needed. Alterations to take in a garment are much easier than letting one out. If one measurement is larger than the others, use that as your primary guide.
Yes, sizing is not fully standardized globally. A US size 6 and a UK size 10 are typically equivalent, but a brand in Italy or France may cut slightly smaller than an American brand in the same numeric size. This calculator provides standard guideline sizes — always check the specific brand's size chart when shopping internationally. Check out our Shoe Size Conversion Calculator as well.
