Finding The Perfect Fit with UGG Since 1974

If you already know your ordinary shoe size: Use your ordinary size and refer to our size chart here, to work out your Ugg size. We find that US sizing (as opposed to European sizing) is the most consistent sizing to work from.

If you are unsure of your ordinary shoe size: You can download our At-Home Size Guide to find your perfect fit.

If you are a true half size: We recommend using our At-Home Size Guide above to choose your size. Please keep in mind that Ugg boots will stretch approximately half a size, so you should ensure your boots are firm to start with, as they will stretch over time. If you are sometimes a half size, and sometimes a full size, then you are likely to be safe choosing your default full size (e.g. if you are sometimes a 7 and sometimes a 7.5, then choose a 7, but if you are sometimes a 7.5 and sometimes an 8, then choose an 8). However, measuring your feet and using our guide is always the most accurate method to find your perfect fit.

If you are choosing Slippers or Slides: 

For all slipper styles including the Taryn: 

Due to the style of our open-back Slippers , we recommend choosing your ordinary AU/US/EU size, and this will automatically convert to a size down in our Ugg sizing. Please note the ugg size will be shown on the tags upon arrival.

For Slides: 

The above applies, however, if you prefer an extra snug fit, you could choose to size down in your ordinary AU/US/EU size, which will then convert to two sizes smaller in our ugg sizing.

For Ankle Slippers:

Our Ankle slippers offer a wide ankle fit so please note, these are not to be worn as a snug slipper, but something to easily slide into, offering a roomier fit. Some customers may choose to size down for a more snug fit, or prefer our Halfies for a true snug fit.
