Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
A one-unit-per-point scale meeting an arbitrary one
Men's EU shoe sizes, like women's, are built from the French Paris-point system — each point equal to two-thirds of a centimetre of last length — while the US men's scale climbs in an arbitrary set of half-size increments that were never tied to that unit. On the standard chart a US 9 lands on a EU 42, and the gap between adjacent US half sizes doesn't always translate to a full EU point, so the printed table is the closest common midpoint across brands rather than an exact match for any specific shoe.
Dress shoes and athletic shoes from the same brand can convert slightly differently in practice, because dress lasts are frequently built on older, narrower European block shapes while athletic lasts are updated more often to match broader, more contemporary foot-shape research. A EU size that fits well in a brand's sneaker line isn't a guarantee the same EU number fits the same in that brand's oxford line.
Width sizing barely exists on the EU side
US men's dress shoes commonly offer a width letter (D standard, E and EE wide) alongside the length number, a system most EU shoemakers don't use at all — continental brands typically build one width per size and expect the last shape itself to accommodate the range, rather than offering a separate wide option. A man who normally buys an EE-width US dress shoe has no direct EU equivalent to ask for; sizing up half a EU size, or choosing a brand known for a roomier forefoot, are the two workarounds worth knowing before ordering internationally.
What to check before an unseen purchase
Convert to actual foot length in centimetres rather than trusting the size-number shortcut, and note whether the shoe is a dress style (more likely built on an older, narrower block) or an athletic style (more likely built on a modern, wider last) before assuming the standard conversion table applies equally to both.
Seasonal collections add another wrinkle
Continental shoemakers frequently rework a last between seasonal collections more than US brands typically do for a given model line, so a EU size that fit a past season's version of a shoe isn't a guaranteed match for the current season's version, even from the same brand and even at the identical printed EU number — a detail that matters more when reordering a European brand you haven't bought from in a year or two than it does for a US brand with a more static size run.
Frequently asked questions
Does a US 9 always convert to a EU 42?
It's the commonly published midpoint, but dress shoes and athletic shoes from the same brand don't always convert identically, since dress lasts are often built on older, narrower European block shapes than athletic lasts.
Is there a EU equivalent to a US wide (EE) width?
Not usually as a labeled option — most EU shoemakers build one width per size rather than offering a separate wide line the way US dress-shoe brands do. Sizing up half a EU size is the common workaround.
Why does my EU size feel different in a sneaker versus a dress shoe from the same brand?
Athletic lasts are updated more frequently to reflect current foot-shape research, while dress lasts often carry over older, narrower European block proportions — the size number can be identical while the actual fit differs between the two lines.
Should I round up when my US size converts to a EU half-point?
Generally yes for dress shoes on narrower lasts, since there's no wide-width option to fall back on if the length is tight; for athletic shoes on modern lasts, round to the nearer whole EU size the brand actually stocks.
Do European sock or insole thickness conventions affect the size I should order?
Slightly — continental dress shoes are often worn with thinner dress socks than typical in the US, so a EU size converted for a thicker American dress-sock habit can feel marginally tighter than expected; factor that in if you plan to wear the shoe with heavier socks.
