The same foot is called a 9 in the US women's scale, a 7 in the UK, and roughly a 40 in Europe \u2014 and US men's and women's scales differ from each other by a full size. When shopping internationally, ordering online, or buying shoes from a foreign brand, you constantly need to translate between these systems. This converter does all the translations at once from a single input.<\/p>\n<p>Behind the scenes, every size system is tied to a physical foot length. The UK and US scales are based on barleycorns (one third of an inch per size step), while the EU scale is based on Paris points (two thirds of a centimetre per size step), each with a fixed allowance between the foot and the shoe last. Because both scales ultimately measure the same foot, any size can be converted to any other by first recovering the foot length and then re-expressing it in the target system.<\/p>\n<p>The results are rounded to the nearest half size, which is the standard step used in retail for US and UK sizes. Your foot length in cm and inches is shown as well, since many brands now print the recommended foot length on the shoe box or size chart \u2014 often the most reliable way to pick a size.<\/p>\n<h2>Reference Table: Common Women's Sizes<\/h2>\n<table>\n<thead>\n<tr>\n<th>US Women's<\/th>\n<th>US Men's<\/th>\n<th>UK<\/th>\n<th>EU<\/th>\n<th>Foot length (cm)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>6<\/td>\n<td>5<\/td>\n<td>4<\/td>\n<td>36.5<\/td>\n<td>22.9<\/td>\n<\/tr>\n<tr>\n<td>7<\/td>\n<td>6<\/td>\n<td>5<\/td>\n<td>38<\/td>\n<td>23.7<\/td>\n<\/tr>\n<tr>\n<td>8<\/td>\n<td>7<\/td>\n<td>6<\/td>\n<td>39<\/td>\n<td>24.5<\/td>\n<\/tr>\n<tr>\n<td>9<\/td>\n<td>8<\/td>\n<td>7<\/td>\n<td>40.5<\/td>\n<td>25.4<\/td>\n<\/tr>\n<tr>\n<td>10<\/td>\n<td>9<\/td>\n<td>8<\/td>\n<td>41.5<\/td>\n<td>26.2<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Tips, Assumptions and Limitations<\/h2>\n<ul>\n<li><strong>Measure your feet at the end of the day.<\/strong> Feet swell during the day, so an evening measurement gives the size that will fit all day. Stand with your heel against a wall, mark the tip of your longest toe, and measure the distance.<\/li>\n<li><strong>Measure both feet.<\/strong> Most people have one slightly longer foot; use the longer measurement.<\/li>\n<li><strong>Brand sizing varies.<\/strong> This converter uses the standard barleycorn and Paris point scales, which match most mainstream brands. Individual manufacturers may run half a size or more larger or smaller, so always check the brand's own size chart when available.<\/li>\n<li><strong>Children's sizes differ.<\/strong> The calculator implements the adult scales. UK children's sizes share the same barleycorn arithmetic, but US children's sizes have their own numbering, so treat children's conversions with caution.<\/li>\n<li><strong>Width is not accounted for.<\/strong> Size systems only describe length. If you have wide or narrow feet, look for shoes in multiple width fittings.<\/li>\n<\/ul>\n<p>For other everyday conversions \u2014 for example the <a href=\"https:\/\/wpcalc.com\/en\/converters\/meters-to-feet\/\">meters to feet converter<\/a> for length or the <a href=\"https:\/\/wpcalc.com\/en\/converters\/fahrenheit\/\">Fahrenheit to Celsius converter<\/a> for temperature \u2014 WPCalc offers a full set of free unit converters.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convert between US men's, US women's, UK and EU shoe sizes, or enter your measured foot length in cm or inches to see your size in every system at once.<\/p>\n","protected":false},"author":3168,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[3],"tags":[31],"class_list":["post-65419","post","type-post","status-publish","format-standard","hentry","category-converters","tag-other-units"],"acf":[],"_links":{"self":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/65419","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/users\/3168"}],"replies":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/comments?post=65419"}],"version-history":[{"count":2,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/65419\/revisions"}],"predecessor-version":[{"id":65722,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/65419\/revisions\/65722"}],"wp:attachment":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/media?parent=65419"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/categories?post=65419"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/tags?post=65419"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
