🌍 Convert Your Size
What is the International Sailing Size Converter?
Buy a pair of deck shoes in Antibes, a jacket in Cowes, and a polo online from the States, and you will meet three different sizing systems. This converter maps your size across US, UK, and EU standards for four common sailing-wardrobe garment types, so you can shop any port's boutique — or any website — without second-guessing the label.
Pick your garment, tell it the region and size you already know, and it returns the equivalent in all three systems from documented conversion charts. Sizing still varies by brand and cut, so check the maker's own chart before ordering.
❓ Frequently Asked Questions
How do US, UK, and EU sizes differ for sailing gear?
The three systems use different scales. For shoes, a US men's 10 is roughly a UK 9.5 and an EU 44 — the UK number runs about half a size below the US, while the EU number is on an entirely separate metric scale. Tops split too: US and UK often share alpha sizes (S, M, L) while the EU uses numeric sizes like 48 or 50. This converter shows the equivalent across all three from any one you know.
Why do deck shoes fit differently between brands?
Even at the same nominal size, lasts (the foot-shaped mould a shoe is built on) vary between makers, and boat shoes are often worn without socks, which changes the fit you want. Use the conversion as a starting point, then check the specific brand's chart and reviews — many sailing-shoe brands run slightly large or narrow.
Should I size up for sailing layers?
For mid-layers and shells you plan to wear over other clothing, sizing up a little gives room for a fleece or base layer underneath and freedom of movement on deck. For close-fitting tops like Breton shirts, stick to your true size. The converter gives you the equivalent size; whether to go up is a fit-and-layering decision.
Are these conversions exact?
They follow standard published charts, but sizing varies by brand, cut, and country of manufacture, so treat them as a reliable guide rather than a guarantee. Always check the manufacturer's own size chart before ordering, especially for shoes and tailored jackets.
