For one thing, there are often entries missing. Want to know how to get 22 EPI in a 10 dent reed, or 17 EPI in an 9 dent reed? Good luck finding a chart that includes those options! <\/p>\n\n\n\n<p>For another, charts don\u2019t explain the math behind the calculations, which means <em>you stay dependent on the chart<\/em> to provide magical answers. The math isn&#8217;t tricky, so there&#8217;s no reason you can&#8217;t be independent and work out exactly how to get the sett you want <em>in the reeds you already own<\/em>.<\/p>\n\n\n\n<p>Our denting calculator &#8211; which members can find in the Weavers Toolbox, will tell you how to get any sett from any reed.<\/p>\n\n\n\n<p>If all you need at This Moment Right Now is that answer, then by all means head to the calculator and get what you need so that you can carry on with your project!

Leave the remainder, if any, as a fraction.<\/li>\n\n\n\n<li>Reduce the remainder as far as possible.<\/li>\n\n\n\n<li>The whole part of the answer is the number of threads to put in every dent.<\/li>\n\n\n\n<li>The fraction tells you how many dents (the numerator) out of how many dents (the denominator) get an extra thread.<\/li>\n<\/ol>\n\n\n\n<p>The math is exactly the same for metric, just use ends per cm (or 10cm) and dents per cm (or 10cm).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Example 1: 20 EPI in a 12 dent reed<\/h2>\n\n\n\n<p>Say you have a 12 dent reed and you need to sley it at 20 ends to the inch. That means you need to divide 20 (the EPI) by 12 (the DPI):<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized ha-caption\"><img decoding=\"async\" src=\"https:\/\/my.handweavingacademy.com\/wp-content\/uploads\/2023\/03\/denting-long-division-1024x642.png\" alt=\"\" class=\"wp-image-86896\" style=\"aspect-ratio:1.5950155763239875;width:600px;height:auto\"\/><figcaption class=\"wp-element-caption\">Remember your long division days?
