In December 2013 Google opened <strong>custom AdSense ad sizes<\/strong> to every publisher, a feature that was once a perk for premium publishers. You can still create a fixed-size display ad of almost any width and height in 2026, as long as you follow Google&#8217;s size rules. Here&#8217;s how, plus when a responsive ad is the better choice.<\/p>\n<p><strong>Quick answer:<\/strong> In AdSense, go to Ads &gt; By ad unit &gt; Display ads, choose Fixed instead of Responsive and enter your width and height. Width must be at least 120 px and height at least 50 px, neither can exceed 1200 px, and only one dimension can be over 450 px. Google recommends responsive ads for responsive sites.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_89 counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-6af64cb0c62d9\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #1a202c;color:#1a202c\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #1a202c;color:#1a202c\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6af64cb0c62d9\" checked aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#Custom_AdSense_ad_size_rules\" >Custom AdSense ad size rules<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#How_to_create_a_custom_size_AdSense_ad\" >How to create a custom size AdSense ad<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#Custom_size_vs_responsive_ads\" >Custom size vs responsive ads<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#Will_custom_sizes_earn_less\" >Will custom sizes earn less?<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#Tips_for_custom_ad_sizes\" >Tips for custom ad sizes<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#FAQ\" >FAQ<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#What_is_the_maximum_AdSense_ad_size\" >What is the maximum AdSense ad size?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#Can_I_change_the_size_of_an_existing_AdSense_ad_unit\" >Can I change the size of an existing AdSense ad unit?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/12\/how-to-create-adsense-ads-of-any-size\/#Are_responsive_AdSense_ads_better_than_fixed_sizes\" >Are responsive AdSense ads better than fixed sizes?<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Custom_AdSense_ad_size_rules\"><\/span>Custom AdSense ad size rules<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to <a href=\"https:\/\/support.google.com\/adsense\/answer\/9185043?hl=en\" target=\"_blank\" rel=\"noopener\">AdSense Help<\/a>, fixed-size display ads must follow these limits, or they won&#8217;t show:<\/p>\n<ul>\n<li>Minimum width: 120 pixels.<\/li>\n<li>Minimum height: 50 pixels.<\/li>\n<li>Maximum width or height: 1200 pixels.<\/li>\n<li>Only one dimension can be larger than 450 pixels.<\/li>\n<\/ul>\n<p>In 2013 the rule was stricter: only one dimension could exceed 300 pixels.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_create_a_custom_size_AdSense_ad\"><\/span>How to create a custom size AdSense ad<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol>\n<li>Sign in to AdSense and open <strong>Ads &gt;
