UGG Size Guide
UGG is renowned for premium sheepskin footwear and apparel designed for comfort and durability. The brand specialises in boots, slippers, shoes, and accessories crafted with signature UGG sheepskin lining. UGG sizing follows standard UK, US, and EU conventions, though customers should note that sheepskin naturally compresses with wear—boots may feel snug initially but will loosen as the plush lining settles. Most customers find their regular footwear size offers the best fit, though some prefer sizing up by half a size if between measurements.
How to Measure
- For footwear: Remove your shoes and socks. Stand on a flat surface with your weight evenly distributed.
- Measure from the back of your heel to the tip of your longest toe using a ruler or measuring tape.
- Record the measurement in centimetres. If it falls between two sizes, round up to the next size.
- For clothing: Wear a thin, well-fitted shirt. Measure around your chest at the fullest point, keeping the tape parallel to the ground and not too tight.
- For waist and hip measurements, position the tape at your natural waist and fullest hip point respectively.
- Compare your measurements against the relevant size chart table below.

Product-Specific Guidance
Boots (Classic UGG Styles): UGG boots feature a notably plush sheepskin lining that compresses significantly over the first few weeks of wear. Expect the opening and overall fit to loosen as the sheepskin settles. Purchasing your regular footwear size is recommended. If you find the boot opening too narrow to slip your foot in comfortably, a shoe horn will help ease entry.
Mini and Ultra Mini Boots: These styles have a narrower boot opening than classic models. Customers report difficulty during initial wear. We strongly recommend using a shoe horn to assist with putting on the boot. The pull tag at the back aids removal but should be handled carefully to avoid damaging the stitching. With time and wear, the opening will loosen slightly for a more comfortable fit.
Slippers: UGG slippers provide a cosy, snug fit due to the plush sheepskin lining. Measure your foot length carefully and select your standard UK or US shoe size. The sheepskin will compress with regular wear, creating a more relaxed fit.
Shoes and Casual Footwear: Apply the same measurement method as for boots. UGG's casual shoes and loafers follow standard sizing conventions. Allow for slight compression of any sheepskin lining present.
Clothing and Accessories: UGG's apparel and beanies follow conventional sizing. For clothing, measure your chest, waist, and hips carefully. If measurements fall between two sizes, select the larger size for comfort. Beanies and hats are sized by head circumference; measure around the widest part of your head, just above the eyebrows and ears.
Sizing Tips
- Account for sheepskin compression: The fluffy sheepskin lining compresses with wear. Initial snugness will ease significantly after a few weeks of use. Do not size up excessively to compensate for this natural settling.
- Use a shoe horn for tight openings: If you struggle to slip your foot into Mini, Ultra Mini, or other narrow-opening boots, a shoe horn is an invaluable tool. Insertion will become easier as the sheepskin relaxes.
- Measure barefoot on a flat surface: Always measure your feet without shoes or socks, with your weight distributed evenly. Measurements taken whilst sitting or wearing thick socks may result in an incorrect size.
- Size up if between measurements: If your foot length falls between two sizes, choose the larger size for maximum comfort. This is especially important given the sheepskin compression factor.
- Protect the pull tag: When removing boots with a pull tag, handle it gently and pull straight upwards to avoid stressing the stitching. Aggressive pulling can damage the tag.
- Allow a break-in period: New UGG boots and shoes may feel tight initially due to the thick sheepskin lining. Wear them for short periods over several days to allow the lining to soften and mould to your foot shape.
- Check for draft and warmth: UGG sheepskin naturally insulates, so choose your size based on fit rather than warmth expectations. An oversized boot will create cold spots; a properly fitted boot will maximise thermal comfort.
