Women's size guide

Australian shoe sizes are equal to American shoe sizes, so if you're purchasing footwear from a US-based retailer, you should find the fit is the same.

If you're buying from a UK-based store, go down 2 sizes. If you're a 7 in Australia, you're a 5 in the UK.

AU size	UK size	EU size	US size	Japan	Foot length (mm)
4	2	35	4	21	228
5	3	36	5	22	235
6	4	37	6	23	241
7	5	38	7	24	248
8	6	39	8	25	254
9	7	40	9	26	260
10	8	41	10	27	267
11	9	42	11	28	273

Men's size guide

Australian men's shoe sizes are equal to shoe sizes in the UK.

If you're shopping from an American store, you'll need to go up one size to get the right fit. So, if you're a 9 in Australia, you'll be a 10 in the US.

AU size	UK size	EU size	US size	Japan	Foot length (mm)

Baby shoe size guide (pre-walking)

Baby shoe sizes are the same in Australia as they are in the UK. They are one size smaller than American shoes.

If you're buying from a store that uses Japanese sizes, the shoe size is roughly the same (but slightly higher) than the length of the foot. For example, if your baby's foot is between 99 and 104, a size 10 should fit.

AU size	UK size	EU size	US size	Japan	Foot length (mm)
-	-	15	-	9	84-90

6	6	23	8	15	140-145

Toddler size guide

Like baby and men's shoes, toddler shoe sizes are the same if they are Australian or British.

American shoe sizes are one size higher than they are in Australian. So if you need an Australian size 8, you'll need a 9 from an American store.

Japanese sizes are roughly the same as the length of the foot in centimetres.

AU size	UK size	EU size	US size	Japan	Foot length (mm)
5	5	22	6	13.5	133-139

Young kids size guide

Similar to toddler, baby and men's shoes, shoes made for young kids are sized the same if they are Australian or British.

If you're purchasing footwear from an American store, you'll need to buy one size larger than you would from an Australian store.

Japanese sizes are roughly the same in size as the length of the foot in centimetres.

AU size	UK size	EU size	US size	Japan	Foot length (mm)
8	8	25	9	15.5	153-159

Older kids size guide

For older children, Australian sizes are equal to UK sizes, so if you're buying shoes from a UK-based store, you can purchase them in the same size and they should fit.

If you're looking at a US-based store, buy the shoes one size larger than you normally would in Australia.

AU size	UK size	EU size	US size	Japan	Foot length (mm)
1	1	33	2	9.5	207-213

Frequently asked questions about shoe sizes

Do shoe sizes go by inches?

No, shoe sizes don't directly represent the length of your foot in inches. Some places, including Japan, do have sizing that's similar to the size of the foot in centimetres. Although not a perfect match, you can find approximate foot lengths in millimetres compared to the corresponding Japanese shoe size in the chart above.

---

Do shoe sizes vary by brand?

Occasionally shoe sizes can seem to vary brand by brand by up to half a size, so when possible, it's always worth trying the shoes on first. Alternatively, look for online retailers with free returns policies. For the chart above, we've done our research and based the conversion on the majority of online retailers, but if you're thinking of buying from a specific retailer, check its own conversion chart if it has one.

---

How do men's shoe sizes compare to women's?

Australian men's sizes are approximately 2 sizes bigger than women's. For example, an Australian women's size 9 would be an Australian men's size 7. It's often hard to tell if a supplier is listing their shoe size in AU, UK or US sizes, so we find the best way is to check your European shoe size and use that as a guide.

---

Does shoe size determine height?

While shoe size is not a definite factor in height, there has been a general correlation drawn by data analysts such as StatCrunch. Often taller people tend to have larger feet, though this is not absolute.

---

How can I convert shoe sizes?

The easiest way to convert shoe sizes is to use a shoe size conversion chart, like the one above.

---

How can I measure my shoe size at home?

Our shoe sizes above also include a column with the length of your foot in millimetres so you can compare the length to a shoe size. For example, if you're looking for a women's shoe and your foot measures 248mm, then you can wear a 7 in Australia or the US, 5 in the UK, 38 in Europe or 24 in Japan.
