This prevents the page from rearranging its elements as images load, leading to a faster-perceived load time.<\/li>\n\n\n\n<li><strong>Enhances user experience:<\/strong> Explicit dimensions prevent layout shifts, a critical factor in providing a stable and enjoyable browsing experience for the users.<\/li>\n\n\n\n<li><strong>Boosts SEO:<\/strong> Search engines, like Google, use page speed and user experience as ranking factors. A stable layout and faster load times can contribute to better search engine rankings.<\/li>\n<\/ol>\n\n\n\n<p>In the screenshot below, this recommendation frequently appears during performance evaluations conducted with <a href=\"https:\/\/pagespeed.web.dev\/\" data-type=\"link\" data-id=\"https:\/\/pagespeed.web.dev\/\" target=\"_blank\" rel=\"noreferrer noopener\">PageSpeed Insights<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1222\" height=\"431\" src=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/explicit-width-height-warning-pagespeed-insights.png\" alt=\"\" class=\"wp-image-2161\" srcset=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/explicit-width-height-warning-pagespeed-insights.png 1222w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/explicit-width-height-warning-pagespeed-insights-300x106.png 300w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/explicit-width-height-warning-pagespeed-insights-1024x361.png 1024w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/explicit-width-height-warning-pagespeed-insights-360x127.png 360w\" sizes=\"(max-width: 1222px) 100vw, 1222px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"fix-the-width-and-height-of-an-image-in-html\"><\/span>Fix the width and height of an image in HTML<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A straightforward method involves using the <code>width<\/code> and <code>height<\/code> attributes within the <code>img<\/code> tag to establish the dimensions of an image in HTML in pixels.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<div class=\"hcb_wrap\"><pre class=\"prism line-numbers lang-plain\"><code>&lt;img src=&quot;your-image.jpg&quot; width=&quot;300&quot; height=&quot;200&quot; alt=&quot;image description&quot;&gt;<\/code><\/pre><\/div>\n\n\n\n<p>You can change the width and height values according to the preferred dimensions. However, it&#8217;s important to note that hardcoding these attributes without proper CSS can lead to issues with image responsiveness, because images need to adapt to various screen sizes and resolutions. Manually setting these attributes without responsive design considerations can cause images to appear distorted or improperly sized on mobile devices or different screen sizes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"set-the-height-and-width-using-block-settings\"><\/span>Set the height and width using block settings<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>You can also adjust the width and height of an image by accessing the &#8216;Block Settings&#8217; panel on the right-hand side and navigating to the &#8216;Settings&#8217; section. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1746\" height=\"156\" src=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/wordpress-block-settings.png\" alt=\"\" class=\"wp-image-2167\" srcset=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/wordpress-block-settings.png 1746w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/wordpress-block-settings-300x27.png 300w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/wordpress-block-settings-1024x91.png 1024w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/wordpress-block-settings-360x32.png 360w\" sizes=\"(max-width: 1746px) 100vw, 1746px\" \/><\/figure>\n\n\n\n<p>Once you click an image, you can see and adjust the dimensions by directly inputting specific pixel dimensions in the &#8216;Width&#8217; and &#8216;Height&#8217; boxes. Additionally, percentage adjustments are available below.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"379\" height=\"901\" src=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/auto-width-height-wordpress-block-editor.png\" alt=\"\" class=\"wp-image-2168\" srcset=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/auto-width-height-wordpress-block-editor.png 379w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/auto-width-height-wordpress-block-editor-126x300.png 126w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/auto-width-height-wordpress-block-editor-215x512.png 215w\" sizes=\"(max-width: 379px) 100vw, 379px\" \/><\/figure>\n\n\n\n<p>However, when set to &#8220;Auto,&#8221; the percentage adjustments allow the image to dynamically resize based on the available space and layout constraints of the webpage. This means that the image will scale proportionally to fit the container or screen width, ensuring optimal display across various devices such as desktops, tablets, and mobile phones.<\/p>\n\n\n\n<p>Manually inputting specific pixel dimensions might not account for the varying screen sizes and resolutions of different devices, potentially leading to images that are too large or too small on certain screens. Leaving the percentage adjustments on &#8220;Auto&#8221; enables WordPress to handle the resizing automatically.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"easy-way-to-add-missing-width-and-height-attributes\"><\/span>Easy way to add missing width and height attributes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you encounter width and height issues across your WordPress website with many images, the easiest way to fix it is by implementing a website accelerator plugin like <a href=\"https:\/\/fastpixel.io\/fr\/\" data-type=\"link\" data-id=\"https:\/\/fastpixel.io\/\" target=\"_blank\" rel=\"noreferrer noopener\">FastPixel<\/a>, which offers the feature to address this concern and boost the core web vitals.<\/p>\n\n\n\n<p>Once installed, you can simply navigate to the <strong>WordPress admin area <\/strong>&gt; <strong>FastPixel <\/strong>&gt; <strong>Settings <\/strong>&gt; <strong>Images<\/strong>, and tick the &#8220;I<strong>mage Sizes<\/strong>&#8221; checkbox to add the missing width and height to image elements.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1616\" height=\"499\" src=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/add-missing-width-height-fastpixel.png\" alt=\"\" class=\"wp-image-2163\" srcset=\"https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/add-missing-width-height-fastpixel.png 1616w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/add-missing-width-height-fastpixel-300x93.png 300w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/add-missing-width-height-fastpixel-1024x316.png 1024w, https:\/\/fastpixel.io\/wp-content\/uploads\/2024\/02\/add-missing-width-height-fastpixel-360x111.png 360w\" sizes=\"(max-width: 1616px) 100vw, 1616px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Setting explicit width and height attributes for image elements in WordPress is a simple yet effective way to improve your website&#8217;s loading time, user experience, and SEO. <\/p>\n\n\n\n<p>Whether you prefer manual adjustments, the convenience of a plugin such as FastPixel, ensuring your images are properly configured is essential for a professional and efficient website.<\/p>\n\n\n\n<div class=\"wp-block-group has-border-color has-palette-color-4-border-color has-palette-color-6-background-color has-background is-vertical is-content-justification-left is-layout-flex wp-container-core-group-is-layout-e21fc307 wp-block-group-is-layout-flex\" style=\"border-width:1px;border-radius:20px;margin-top:var(--wp--preset--spacing--60);margin-bottom:var(--wp--preset--spacing--60);padding-top:var(--wp--preset--spacing--60);padding-right:var(--wp--preset--spacing--60);padding-bottom:var(--wp--preset--spacing--60);padding-left:var(--wp--preset--spacing--60)\">\n<h3 class=\"wp-block-heading\" style=\"margin-top:0;margin-right:0;margin-bottom:0;margin-left:0;padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\">Give FastPixel a try for free<\/h3>\n\n\n\n<p>Take a brief pause to check the performance of your WordPress site for free and measure the before and after results to see the value FastPixel adds to your site.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/test.fastpixel.io\/\">Commencer<\/a><\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>One common issue that can slow down your WordPress site and cause layout shifts is when image elements don&#8217;t have explicit width and height attributes set.
