Questions
Which length does UGG's size chart list?
UGG's charts give these lengths — Women's footwear, Men's footwear, All-gender footwear: JP: size in cm, given by the brand as foot length; Big Kids (4-10 years), Toddlers (1-5 years): JP: size in cm, given by the brand as foot length · Mondopoint: size in cm, given by the brand as foot length. A measured foot length and a size in cm are about 8 mm apart for the same size, so compare your own foot length only with a column on the same scale.
Does the official chart tell me how a UGG shoe will fit?
Only in part. The chart gives the length each size is meant for; how a particular model fits also depends on its last, width and materials, which the chart does not show. UGG itself advises: Measure both feet from heel to longest toe and use the larger measurement with the conversion chart. All sizes on the site are shown in US measurements; the chart converts them to international sizes.
When should I not compare UGG sizes with another brand?
When the two charts list different lengths. A measured foot length and a size in cm are about 8 mm apart, and the length of a foot is not the inside length of a shoe, so such a match can be half a size or more off. The converter matches only lengths on the same scale and lists the other brands separately.
When was UGG's chart last checked?
On 2026-10-24, against UGG's official size guide linked under each chart. The date changes only when the chart is checked again against the official page or its numbers change, not when this page's layout or wording changes.
