Find your perfect UGGAUS fit
Choosing the right size helps your UGG boots, slippers and shoes feel more comfortable from the first wear. Use the size charts below as a general guide and measure your foot length before ordering.
UGG footwear with sheepskin or wool lining may feel slightly snug at first. This is normal, as the lining will gently settle with wear.
1. How to measure your foot

- Place a sheet of paper on the floor against a wall.
- Stand on the paper with your heel touching the wall.
- Mark the longest point of your foot, usually the big toe or second toe.
- Measure from the wall to the mark in centimetres.
- Repeat with the other foot and use the longer measurement.
- Compare your foot length with the size chart below.
For the most comfortable fit, measure your feet in the afternoon or evening, when they are naturally at their largest. If you are between sizes, we recommend choosing the larger size, especially for boots or lined slippers.

For kids, always measure both feet before choosing a size. Children’s feet grow quickly, so allow a little extra room for comfort, but avoid choosing footwear that is too large, as it may affect support and stability.
5. Fit tips for UGG footwear
UGG boots and slippers are often designed with soft lining, so they may feel snug when new. This snugness should feel comfortable, not tight or painful.
For the best fit:
- Choose the size that matches your longer foot.
- Size up if you are between sizes.
- Size up if you have wider feet or prefer extra room.
- Wear your usual socks when measuring.
- Check the product page for any style-specific fit notes.
