How do I convert a clothing size between US, UK, EU and S/M/L?

AnyTool Clothing Size Converter instantly shows the matching size in every other system, anchored on body measurements in centimetres. A measure-yourself helper turns your bust/chest, waist and hips into a recommended size in each system. Everything runs in your browser, so nothing is uploaded.

What is

Clothing Size Conversion

Clothing size conversion maps a garment size from one regional system to another — for example a women’s US 8 to a UK 12 or EU 40. Because the US, UK and EU number lines start at different points, because the International alpha scale (XS–XXL) spans several numbers, and because the scales differ for women, men and children, conversion is done from published charts rather than a single formula. Body measurements in centimetres — bust or chest, waist and hips — are the most reliable anchor, since clothing sizing is not standardised and drifts by brand and over time (“vanity sizing”).

Frequently Asked Questions

For women, a US 8 is usually a UK 12 and an EU 40, which is an International M and fits a body with about a 92 cm bust, 75 cm waist and 100 cm hips. Men and kids use different scales, which is why AnyTool asks for your category first and uses a separate chart for each rather than one universal table.

Take three body measurements with a soft tape, keeping it level: bust or chest at the fullest point, waist at the narrowest part of your torso, and hips at the widest. Enter them into AnyTool’s measure-yourself helper in centimetres or inches and it recommends a size in US, UK, EU and S/M/L, rounding up when you fall between sizes. These are body measurements, not garment measurements, so the right size leaves room to move.

Use a soft tape over light clothing: measure bust/chest at the fullest part, waist at the narrowest, hips at the widest.

Clothing sizing is not standardised like metric units, and varies even more than shoe sizing — the same labelled size fits differently across brands and cuts, and vanity sizing has shifted the numbers over time. AnyTool’s conversions are built from published charts and are best-estimate guides. The surest approach is to measure your bust/chest, waist and hips in centimetres, match the measurement columns, then confirm against the specific brand’s size guide; when between two sizes, size up.

No. Sizing isn’t standardised, so the same label fits differently by brand — always check the brand’s own chart.

AnyTool Clothing Size Converter computes everything locally in JavaScript using stored conversion rows for women, men and kids. No size or body measurement is sent to a server, there is no tracking, and the page keeps working offline after the first load.

Detailed Explanation

Methodology

How the Clothing Size Converter Works

AnyTool Clothing Size Converter is chart-based rather than formula-based, because the US, UK and EU number lines start at different offsets, the International alpha scale (XS–XXL) spans several numbers, and the scales themselves differ for women, men and children. The tool stores real conversion rows for each category — and for men, separate charts for tops (sized by chest) and trousers (sized by waist) — where every row carries its body-measurement range in centimetres. When you enter a size in any system it locates the matching row and shows the equivalent in every other system, plus the bust/chest, waist and hips that size corresponds to. Body measurement is the anchor because clothing sizing is not standardised: brands vary, and “vanity sizing” has shifted the numbers over time, whereas a centimetre is fixed.

Four systems: US, UK, EU and International alpha (XS–XXL)
Separate real charts for women, men and kids — they differ
For men, tops are sized by chest and trousers by waist
Every row carries bust/chest, waist (and hips) in centimetres
All conversion runs in the browser — no server round-trip

How It Works

Measure-Yourself Helper and Ease

Beyond converting a known size, the tool turns body measurements into a recommended size in every system. Enter bust/chest, waist and (for women) hips in centimetres or inches; it recommends by the primary measurement for that category — bust for women, chest for men’s tops, waist for men’s trousers — and rounds up when you fall between sizes so the garment is not too tight. Because these are body measurements rather than garment measurements, the right size leaves room to move (ease): for relaxed or non-stretch styles you size up, for fitted or stretch styles you may size down. The page shows the full per-category reference chart with the matched row highlighted and is explicit that results are best estimates.

Privacy & Security

Privacy and Offline Use

Because all conversion runs in the browser from built-in chart data, no size or body measurement is sent to a server, there is no account or tracking, and the page works offline after first load. The logic lives in a pure, unit-tested engine so behaviour is consistent and auditable.

Clothing size conversion: in-browser (AnyTool) vs typical online charts

Categories	Women, men and kids (separate charts)	Often one mixed chart
Garments	Men split into tops vs trousers	Rarely separated
Systems	US, UK, EU and International S/M/L	Frequently US/UK/EU only
Measurement anchor	Yes — bust/chest, waist, hips in cm	Sometimes
Measure-yourself helper	Yes, recommends a size per system	Seldom
Honesty about fit	Explicit best-estimate notice	Often implies exactness
Works offline	Yes (PWA)	No
Cost / signup	Free, no signup	Often ad-heavy or gated

AnyTool converts every system locally through a body-measurement anchor and uploads nothing.

A privacy-first, 100% client-side clothing size converter that translates a size across US, UK, EU and the International alpha scale (XS–XXL) using real, separate conversion charts for women, men and kids — and, for men, separate charts for tops (sized by chest) and trousers (sized by waist). Because clothing sizing is not standardised and drifts by brand and over time (“vanity sizing”), conversion is chart-based and anchored on body measurements in centimetres, with every row carrying its bust/chest, waist and hips range. It includes a measure-yourself helper that turns tape-measure readings into a recommended size in every system — recommending by the right anchor per category and rounding up between sizes — shows the full per-category reference chart with the matched row highlighted, and is explicit that results are best estimates because the same label fits differently across brands and cuts, so users should check the brand’s own size guide — computing everything in the browser and uploading nothing.
