Convert sizes across US, UK, EU and Asia, or get a recommended size directly from your own body measurements — for tops, bottoms, dresses and shoes.
Based on standard international chest/bust ranges. Brand cuts vary — check the brand's own chart if precision matters (e.g. suiting vs. athletic fit).
Men's sizing shown as waist inches (e.g. 32, 34); women's shown as numeric US size (e.g. 6, 8). Rise style and stretch fabric shift real-world fit.
When measurements span two sizes, this defaults to the larger for comfort — take in at the smaller points if needed.
Measure heel to longest toe, standing, in the evening when feet are slightly swollen — the truer real-world size.
Shoe size formulas vary meaningfully by brand and last shape — treat this as a starting point, especially for running or performance shoes.
Each tab uses its own reference chart built from standard international measurement ranges — chest and bust circumference for tops, waist for bottoms, a combination of bust/waist/hip for dresses, and foot length for shoes. Enter your measurements in centimeters or inches, and the closest matching size highlights instantly in the table.
No universal size chart perfectly predicts fit across every brand, because cut, fabric stretch, and target fit (slim, regular, relaxed, athletic) all shift the real-world measurements behind a labeled size. This calculator gives a reliable starting point based on your actual body measurements — treat it as a strong first estimate, and check a specific brand's own chart when a purchase really needs to fit precisely.
Bust, waist, and hip rarely fall into exactly the same size range for every body. When they span two sizes, this calculator recommends the larger of the three matches, since a dress can usually be taken in at the smaller measurement points by a tailor, but sizing down and hoping for stretch is a much less reliable fix.
Foot length is best measured standing (not sitting), from the heel to the tip of the longest toe, and ideally in the evening — feet swell slightly over the course of a day, so an evening measurement reflects real-world sizing more closely than a first-thing-in-the-morning one.
How accurate is a size calculator like this? It's a reliable starting point based on standard international size ranges, but brand cuts vary meaningfully — a size M in one brand's athletic fit can measure differently from a size M in a relaxed or suiting fit. Check the brand's own chart when precision matters.
Why does the dress size default to the largest matching measurement? When bust, waist, and hip measurements fall into different size ranges, sizing up to the largest match is generally more comfortable, since a dress can usually be taken in at the smaller points but not let out much at a smaller size.
How should I measure my foot for shoe sizing? Measure from the heel to the tip of the longest toe while standing, ideally in the evening when feet are slightly more swollen from the day — this gives a truer real-world size than measuring first thing in the morning.
Why do men's and women's bottoms use different size formats? Men's bottoms are conventionally sized by waist measurement in inches (like 32 or 34), while women's bottoms commonly use a numeric US size (like 6 or 8) that doesn't map directly to a single measurement — this calculator follows each convention separately.
