In 2013 we tested the 300&#215;600 large skyscraper AdSense ads (also called the half page ad) in our sidebar, soon after Google released the size. Big advertisers liked it, but we saw some odd variations: single text ads, fallback 160&#215;600 ads and lots of empty space. Here is what we learned then, and how to use 300&#215;600 ads in 2026, when most AdSense sites use responsive ad units.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-33244\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-skyscraper4.png\" alt=\"300x600 large skyscraper adsense ads\" width=\"487\" height=\"515\" srcset=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-skyscraper4.png 487w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-skyscraper4-283x300.png 283w\" sizes=\"(max-width: 487px) 100vw, 487px\" \/><\/p>\n<p><strong>Quick answer:<\/strong> The 300&#215;600 large skyscraper (half page) is still a standard AdSense display ad size and one of the higher-earning formats for desktop sidebars, because it fits large image and video ads. In 2026, use it in a sticky desktop sidebar or let a responsive display ad fill a 300-pixel-wide sidebar, and do not force it on mobile, where it can push content down.<\/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-6ae60de054f45\" 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-6ae60de054f45\" 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\/04\/300x600-large-skyscraper-adsense-ads\/#What_is_a_300%C3%97600_large_skyscraper_ad\" >What is a 300&#215;600 large skyscraper ad?<\/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\/04\/300x600-large-skyscraper-adsense-ads\/#Our_2013_experience_with_300%C3%97600_AdSense_ads\" >Our 2013 experience with 300&#215;600 AdSense ads<\/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\/04\/300x600-large-skyscraper-adsense-ads\/#How_to_use_300%C3%97600_ads_in_2026\" >How to use 300&#215;600 ads in 2026<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/04\/300x600-large-skyscraper-adsense-ads\/#300%C3%97600_vs_other_sidebar_sizes\" >300&#215;600 vs other sidebar sizes<\/a><\/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\/04\/300x600-large-skyscraper-adsense-ads\/#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-6\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/04\/300x600-large-skyscraper-adsense-ads\/#Do_300%C3%97600_ads_earn_more\" >Do 300&#215;600 ads earn more?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/04\/300x600-large-skyscraper-adsense-ads\/#Can_I_use_300%C3%97600_ads_on_mobile\" >Can I use 300&#215;600 ads on mobile?<\/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\/04\/300x600-large-skyscraper-adsense-ads\/#When_did_AdSense_launch_300%C3%97600_ads\" >When did AdSense launch 300&#215;600 ads?<\/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\/04\/300x600-large-skyscraper-adsense-ads\/#Why_does_my_300%C3%97600_ad_show_a_smaller_ad\" >Why does my 300&#215;600 ad show a smaller ad?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2013\/04\/300x600-large-skyscraper-adsense-ads\/#Is_the_300%C3%97600_the_same_as_a_half_page_ad\" >Is the 300&#215;600 the same as a half page ad?<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_300%C3%97600_large_skyscraper_ad\"><\/span>What is a 300&#215;600 large skyscraper ad?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The 300&#215;600 unit is 300 pixels wide and 600 pixels tall. It fits the same width as the popular 300&#215;250 medium rectangle but is more than twice as tall, so it can show a large image ad, rich media, or several text ads stacked together. Google added it to AdSense for all publishers in November 2012, along with other larger &#8220;brand-friendly&#8221; sizes. Google&#8217;s Display Business Trends report had found the 300&#215;600 was one of the fastest-growing premium ad sizes, favoured by brand advertisers because it makes a strong visual impact.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-30700\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-ad.png\" alt=\"300x600 half page AdSense ad in a sidebar\" width=\"500\" height=\"472\" srcset=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-ad.png 500w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-ad-300x283.png 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>We placed it in our sidebar on launch day. At first it showed only text ads, with image ads arriving as more advertisers created creatives in the new size. Our advice then still applies: the unit naturally replaces a 300&#215;250 medium rectangle in the sidebar, but it takes a lot of space, so an above-the-fold placement pushes everything else in the sidebar down.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Our_2013_experience_with_300%C3%97600_AdSense_ads\"><\/span>Our 2013 experience with 300&#215;600 AdSense ads<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Eight text ads with arrows:<\/strong> the common text version looked clean with good white space.<\/li>\n<li><strong>One large image ad:<\/strong> a rich image ad filled the whole space, so that single ad had to be good enough to get the click.<\/li>\n<li><strong>Four text ads:<\/strong> sometimes only four ads showed, leaving a big blank area.<\/li>\n<li><strong>160&#215;600 fallback:<\/strong> when an image ad won the auction, a narrower 160&#215;600 skyscraper sometimes appeared inside the space, which looked awkward in a sidebar designed for 300 pixels.<\/li>\n<li><strong>A single text ad:<\/strong> the worst case, one text ad stretched across a tall space.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter size-full\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/300x600-skyscraper1.png\" alt=\"300x600 skyscraper ads with text ads\" width=\"500\" height=\"519\" \/><\/p>\n<p>Our takeaway then: the 300&#215;600 unit can earn well, but you must design the sidebar so it still looks good when the ad changes shape or size.
