Loafers Size Conversion Chart

How loafers size conversion works

Converting a loafers size between US, UK and EU systems sounds simple, but the three systems were built on different scales, so the numbers do not line up neatly. The US system moves in half sizes, the UK system does too but starts two numbers lower for women's shoes, and the EU system uses a different numbering scale altogether. That is why a single conversion number can be wrong for a particular brand even when it looks right in a general table.

The safest way to convert is to anchor on foot length in inches. Measure your foot, find the row that contains that length, and read across for the US, UK and EU sizes in that row. Foot length does not change between countries, so it stays honest even when brands disagree about the numbers. The US, UK and EU shoe size conversion guide explains how the three systems grew apart.

Conversion chart table in inches

The table below gives the full broad general conversion for women's loafers from US 5 to US 12, with foot length in inches and the matching UK and EU sizes. Use it as a starting guide, and remember that brands grade differently, so the brand chart for the loafers you are buying comes first.

Notice how the UK column runs two sizes below the US column all the way down the table, while the EU column moves in half steps. That steady pattern is what makes the table useful, but it is also what makes it general, because real brands do not all follow the same pattern at every size.

US to UK loafers conversion

In this broad general table, a US women's loafers size converts to a UK size two numbers lower, so US 7 becomes UK 5, US 8 becomes UK 6, and US 9 becomes UK 7. Half sizes follow the same rule, so US 7.5 becomes UK 5.5 and US 8.5 becomes UK 6.5. This two size gap holds across the table, which makes US to UK conversion the most predictable of the three.

Even so, some UK brands grade their half sizes differently, and a brand that sells in both markets may round a conversion up or down at the edges of its range. If you are buying from a UK brand, check whether it lists a US equivalent on its own chart, and if the two disagree, trust the foot length column and the brand chart over the general rule.

US to EU loafers conversion

EU conversion is less tidy than UK conversion, because EU sizes move in half steps that do not match US half steps exactly. In this table, US 7 is EU 38, US 7.5 is EU 38.5, US 8 is EU 39, and US 8.5 is EU 40, so the gap between US and EU numbers changes as you move up the table. That drift is normal, and it is why a straight formula often gives a wrong answer.

When a brand lists only EU sizes, use the foot length column first and the EU column second. A foot length of 9.7 to 9.8 inches points to EU 39 in this table, but a brand that converts generously may call the same foot a 39.5. If the brand also lists an insole length, compare that too, especially for a loafer with a tight vamp or a narrow toe.

UK to EU loafers conversion

UK to EU conversion follows the same table, with UK 5 matching EU 38, UK 6 matching EU 39, and UK 7 matching EU 40.5. Half sizes sit between the whole numbers, so UK 5.5 is EU 38.5 and UK 6.5 is EU 40. The pattern is steady, but the half step jumps are uneven, because EU sizes do not divide evenly across the UK scale.

Why conversions differ between brands

Brands convert differently because they grade from different lasts, which are the foot shaped forms a shoe is built around. A brand that builds on a longer last will call a foot a smaller size than a brand that builds on a shorter last, even when both measure the same foot. Vamp height, heel cup shape and toe taper all change how a converted size feels, so two pairs with the same converted number can fit very differently.

Loafers show this problem clearly, because a tight vamp can make a correctly converted size feel too small, while a loose heel cup can make it feel too large. That is why the conversion chart is only a starting point. Always compare your foot length with the brand chart, read the stated insole length when it is given, and try the loafers size calculator for a starting size with instep and width notes included.
