Women's to Men's Shoe Size: The Simple Conversion (and the Part Everyone Gets Wrong)

The most common question we field in December has nothing to do with leather or lasts. It arrives, in some form, dozens of times a week: "He's a men's 8 — but all I know is my own size. What do I order?" A partner, a father, a brother; a gift she wants to get right without spoiling the surprise by asking.

It's a fair question with a genuinely simple answer — and then a second, quieter part that trips up more people than the maths ever does. Get both right and you'll never guess at a size again, whether you're buying a men's pair for yourself or shopping across the aisle for someone else.

How do you convert a women's shoe size to men's?

To convert a US women's shoe size to men's, subtract 1.5. That's the whole rule. A women's 9 becomes a men's 7.5; a women's 10 becomes a men's 8.5. The two systems are numbered differently, but they're both built on the same underlying foot length — the 1.5 simply translates one scale into the other.

This is the standard used by the major footwear makers — the athletic brands most people cross-shop, and most casual and dress ranges alongside them. It's reliable enough to order from with confidence. The one caveat worth holding in mind: a handful of brands work to a two-size gap rather than 1.5, and some European-lasted ranges differ again, so on an unfamiliar label it pays to glance at the length chart too. More on that below.

How do you convert a men's shoe size to women's?

Going the other way, you simply reverse it: add 1.5 to the men's size. A men's 8 is a women's 9.5. A men's 10 is a women's 11.5. This is the direction men with narrow feet often travel — a women's shoe is cut on a slimmer last, so a narrow-footed man can sometimes find a cleaner fit in the women's version of the same style, sized up by 1.5.

Because the offset is constant, you don't need a chart to do the conversion in your head. But you do need a chart for everything the number doesn't tell you — which is where most sizing mistakes actually happen.

What is a women's size 8 in men's? (and 7, 9, 10)

These are the exact figures people look up most, so here they are, straight from the 1.5 rule:

• A women's 7 is a men's 5.5
• A women's 8 is a men's 6.5
• A women's 9 is a men's 7.5
• A women's 10 is a men's 8.5
• A women's 11 is a men's 9.5

And in reverse, for the gift-buyers:

• A men's 7 is a women's 8.5
• A men's 8 is a women's 9.5
• A men's 9 is a women's 10.5
• A men's 10 is a women's 11.5

If you'd rather not do arithmetic at all, our interactive size converter does it instantly in both directions, with the EU equivalent alongside.

Why are men's and women's shoe sizes 1.5 apart?

The gap is a quirk of history rather than anatomy. Modern shoe sizing descends from an old English system where each full size stepped up by one-third of an inch, with the scale starting from an arbitrary zero point. When a separate women's scale was formalised, it was pinned to a different starting point — offset from the men's by roughly a size and a half. The two grids have run in parallel ever since.

What matters for you is that both scales measure the same thing: heel-to-toe length. A women's 8 and a men's 6.5 are two labels for a foot of the same length. That's why the conversion is so dependable for length — and also why length is only half the story.

Do men's and women's shoes fit the same once converted?

This is the part everyone gets wrong. The length will match perfectly — but the shoe will not necessarily fit the same, because men's and women's shoes are built on differently shaped lasts.

The standard men's last is wider and higher in volume — in width terms, a men's shoe is typically a "D" where a women's is a narrower "B." Men's shoes carry more room through the heel and the ball of the foot. So when a woman orders the converted men's size, the length is right, but the shoe may feel roomier — especially through the heel — than she's used to. And when a man crosses to women's, the reverse applies: the same length in a women's cut will feel snugger and narrower.

None of this makes the conversion unreliable; it just means the number gets you the right length, and a moment's thought about width gets you the right fit. For a fuller walkthrough of how our own lasts break in and mould to the foot, our size guide covers it in detail.

How do US, EU and foot length line up?

Length is the one measurement that never lies, so the most reliable way to size across any two systems is to match the centimetre figure. Here's the full picture — US women's, US men's, the EU equivalent, and approximate foot length — laid out row by row. Read across any row and you're looking at one foot in four different notations.

Treat the EU and centimetre columns as your cross-check. If a brand's own chart disagrees with the simple 1.5 conversion, trust the length. That's the number that reflects your actual foot rather than a label's interpretation of it.

Buying men's shoes as a gift — how to get his size right without asking

Gift-buying is the scenario that sends most people to a conversion chart, and it comes with its own small challenges: you want the right size without tipping off the surprise. A few reliable moves:

Check a shoe he already owns

The size is almost always printed inside — on the tongue, the lining, or the insole. A men's number printed there is exactly what you order. If it shows an EU figure instead, match it to the EU column above.

Convert from a shoe you've borrowed or seen

If all you have is a women's-sized pair he's tried (or your own size as a rough anchor), apply the rule and lean on width. Remember that a men's cut runs wider, so if he's between sizes, the standard advice is to hold the size rather than round up.

When in doubt, choose the style that's easy to exchange

A handmade pair made to order can still be exchanged for a different size within our returns window — so a near-miss is recoverable. Buying from somewhere with a clear size guide and an honest returns policy takes the pressure off the guess entirely.

What if the size lands between two men's sizes?

Because women's sizes convert to men's half-sizes, and many dress and leather ranges are made only in whole sizes, you'll sometimes land between two available options. Here's how to decide:

• Leather shoes with a full lining tend to be snug at first and stretch to the foot — so sizing to the nearer whole size, or slightly down, usually settles into a clean fit.
• Softer, more pliable uppers (like lambskin suede) give more readily, so staying true rather than rounding up avoids a shoe that loosens over time.
• If you're genuinely on the line, match the centimetre length to the brand's chart and let that break the tie.

Our own range is made in whole US men's sizes, and our size guide spells out the between-sizes call for each material — leather, lambskin suede and cowhide suede all behave a little differently.

How do you measure feet for a foolproof conversion?

If you want to remove all guesswork, skip the size labels entirely and measure. It takes two minutes:

• Place a sheet of paper against a wall on a hard floor.
• Stand on it with the heel to the wall, wearing the socks you'd normally wear with the shoes.
• Mark the tip of the longest toe, and measure from the wall edge to the mark in centimetres.
• Match that figure to the foot-length column above — then read across to whichever system you're buying in.

Measure both feet and use the larger; most people have a slightly longer one. Length measured this way beats any conversion rule, because it describes your foot rather than a label. The 1.5 rule gets you close; a tape measure gets you exact.
