class=\"bk-size-lead\"><strong>Find your Br\u00f6Koss ring size quickly and avoid confusing ring-size numbers with measurement units.<\/strong> You can estimate the size from the inside diameter of a ring you already own or from finger circumference, then compare Spain, France\/EU and US sizing systems.<\/p>\r\n\r\n<div class=\"bk-size-warning\">\r\n<p><strong>Important: ring size numbers are not inches.<\/strong><\/p>\r\n<p>US sizes such as <strong>7, 8 or 8.5 are ring-size numbers<\/strong> \u2014 they do not mean 7, 8 or 8.5 inches.<\/p>\r\n<p>When using the calculator below, enter the physical measurement in <strong>millimetres (mm)<\/strong>. If your ruler or tape measure is in inches, convert it first: <strong>1 inch = 25.4 mm<\/strong>.<\/p>\r\n<\/div>\r\n\r\n\r\n<h2>The most reliable way to find your ring size: use a ring sizer<\/h2>\r\n\r\n<p>If the ring is for you and you do not already know your size, our preferred method is to use a <strong>physical ring sizer<\/strong>. It lets you check not only the number itself, but also how the ring passes over the knuckle and how it actually feels once it is sitting on the finger.<\/p>\r\n\r\n<p>Try the most likely size, then compare the size immediately above and below it. The correct fit should pass over the knuckle with slight resistance and then sit securely without feeling painfully tight or spinning continuously.<\/p>\r\n\r\n<div class=\"bk-size-note\">\r\n<p><strong>Ring sizer and ring mandrel are not the same tool.<\/strong> A ring sizer is a set of sample rings worn directly on the finger.
