How to Customize WordPress Admin Icons
Last updated: July 2026
Quick Answer
Learning how to change wordpress admin icons comes down to swapping the Dashicon slug tied to a menu item, either through a small PHP snippet or a plugin’s settings screen. Neither method touches core WordPress files, so both are safe to try and easy to undo.
At Canada Create, we get this request often from clients who manage multi-editor WordPress dashboards and want visual cues to speed up navigation. A courier company we worked with, for instance, wanted an obvious truck icon next to their custom Orders menu instead of the generic default. Small changes like this reduce clicks and confusion for less tech-savvy team members. Our team frequently handles this alongside broader web design work in Yorkville, Toronto for local business clients moving onto WordPress for the first time.
Prerequisites
- Admin access to your WordPress dashboard
- Either FTP/file access and comfort editing functions.php, or the ability to install a plugin
- A staging site or backup, since any functions.php edit carries a small risk of a fatal error if mistyped
If you’re still deciding whether WordPress is the right fit for your business site at all, our comparison of WordPress vs Webflow for B2B covers that broader decision before you get into dashboard-level customization like this.
Step 1: Find the Menu Item’s Page URL Slug
Before you can target a menu icon, you need to know which internal page slug WordPress uses for that menu item. Hover over the menu item in your dashboard and look at the URL shown in your browser’s status bar.
For the default Posts menu, this is typically edit.php. For Pages, it’s edit.php?post_type=page. Custom post types will show their own registered slug.
How to check a custom post type slug
If you’re customizing an icon for a custom post type menu, such as Products or Orders, go to Settings > Permalinks or check your theme’s functions.php where the post type was registered, since the slug is usually visible in the register_post_type() call.
Step 2: Pick an Icon Slug
WordPress ships with the Dashicons icon library built in. Browse the full set on the official Dashicons reference page and click any icon to reveal its slug name, something like dashicons-cart or dashicons-chart-bar.
Using a custom image instead
If none of the built-in icons fit, you can use a custom SVG or PNG. Upload it to your Media Library, copy the file URL, and reference that URL instead of a Dashicons slug in the code below. Keep custom icons small, ideally 20×20 pixels, so they don’t distort in the menu.
Step 3: Add the Code Snippet
Open your theme’s functions.php file (or better, a site-specific plugin or the Code Snippets plugin, so your change survives a theme update) and add the following. This uses the standard admin_menu action hook documented in the WordPress Developer Resources:
function cc_change_admin_icon() {
global $menu;
foreach ($menu as $key => $menu_item) {
if (isset($menu_item[2]) && $menu_item[2] == 'edit.php') {
$menu[$key][6] = 'dashicons-cart';
}
}
}
add_action('admin_menu', 'cc_change_admin_icon');Replace edit.php with the slug you found in Step 1, and dashicons-cart with the slug you chose in Step 2. Save the file and reload your dashboard to confirm the new icon appears.
Editing multiple icons at once
You can extend the same function with additional if conditions inside the loop, one per menu item you want to change. This keeps all your wordpress dashboard icon customization logic in a single function rather than scattering multiple hooks across your codebase.
Step 4 (Alternative): Use a Menu Editor Plugin
If editing PHP directly isn’t something you want to maintain, a menu editor plugin gives you the same result through a visual interface. Search the official WordPress.org plugin directory for an admin menu editor plugin, install and activate it, then navigate to its settings screen (commonly under Settings).
Click into the menu item you want to change, look for an “Icon URL” or similar field, and choose from the built-in icon picker or upload your own image. Save changes and the icon updates immediately, no code required.
Why choose the plugin method
Teams managing several client sites often prefer the plugin route because it’s easier to hand off to a non-technical site owner. It also usually includes a way to reorder or hide entire custom admin menu icons wordpress-wide, not just change their appearance, which functions.php snippets don’t do on their own.
Troubleshooting
- Icon doesn’t change: Double-check the exact slug from Step 1. A typo in the page slug means your condition never matches.
- White screen after saving functions.php: You likely have a syntax error, commonly a missing semicolon or bracket. Restore from backup or fix via FTP, since the dashboard itself may be inaccessible.
- Icon looks blurry or oversized: Custom image icons should be small and ideally SVG format for crisp scaling across screen resolutions.
- Change disappears after a theme update: This happens when the snippet lives inside the active theme’s functions.php. Move it to a child theme or a dedicated snippets plugin so theme updates don’t wipe it out.
Frequently Asked Questions
Will changing admin icons affect my site’s front-end appearance?
No. These changes only affect the wp-admin dashboard menu that logged-in users and editors see. Your public-facing site design is untouched.
Do I need coding experience to change wp-admin icons?
Not necessarily. The plugin method requires no code at all. The functions.php method needs basic comfort copying and editing a short PHP snippet, but no deep programming knowledge.
Can I revert to the default icon if I don’t like the change?
Yes. Simply remove the snippet from functions.php, or in a plugin, click a reset-to-default option if the plugin offers one.
Are there security risks to editing functions.php?
The main risk is a typo causing a fatal error, not a security vulnerability. Still, always keep a backup before editing core theme files, and consider reviewing our guide on securing your WordPress website if you’re making broader dashboard changes at the same time.
Does this work the same way on multisite installs?
Yes, the same functions.php approach works on WordPress multisite, though you’ll typically want to add the snippet to a network-activated plugin so it applies consistently across every site in the network.
