In modern web development in 2026, choosing the right favicon sizes is crucial to ensure your website displays well across various devices and browsers. With the increasing variety of devices and improving screen resolutions, the size requirements for favicons continue to evolve. This article will detail the best favicon size combinations for 2026, including recommended sizes for desktop browsers, mobile devices, PWA applications, and how to choose the right favicon sizes for your website.
Why are Favicon Sizes Important?
The importance of favicon sizes mainly lies in the following aspects:
- Cross-device compatibility: Different devices and browsers have different requirements for favicon sizes. Using the correct sizes ensures that favicons display correctly on all devices.
- Visual effects: Appropriate sizes ensure that favicons maintain clear visual effects across different screen resolutions, avoiding blurriness or distortion.
- Performance optimization: Using appropriately sized favicons can reduce unnecessary network requests and resource consumption, improving website loading speed.
- Brand image: A clear favicon can enhance your website's brand image and improve user recognition.
The Best Favicon Size Combinations for 2026
In 2026, to ensure that favicons display correctly across various scenarios, we recommend using the following size combinations:
1. Desktop Browser Sizes
Desktop browsers are the most common use case for favicons, mainly including the following sizes:
- 16×16 pixels: This is the traditional favicon size, used for browser tabs and address bars. While modern browsers support higher-resolution favicons, 16×16 pixels remains the basic size to ensure compatibility.
- 32×32 pixels: Used for high-resolution desktop screens and desktop shortcuts. With the popularity of 4K and 8K displays, 32×32 pixel favicons can provide clearer display effects on these devices.
- 48×48 pixels: Used for website shortcuts in Windows taskbar and Start menu.
2. Mobile Device Sizes
Mobile devices are an important use case for favicons, mainly including the following sizes:
- 180×180 pixels: Used for home screen shortcuts on iOS devices (Apple Touch Icon). This size is suitable for iPhone, iPad, and iPod Touch devices.
- 192×192 pixels: Used for home screen shortcuts on Android devices and Chrome app launcher.
- 512×512 pixels: Used for PWA (Progressive Web App) installation icons and high-resolution Android devices.
3. PWA Application Sizes
With the popularity of PWA applications, the use of favicons in PWA applications has become increasingly important, mainly including the following sizes:
- 192×192 pixels: Used for PWA application startup icons.
- 512×512 pixels: Used for high-resolution startup icons and installation prompts for PWA applications.
4. Traditional ICO Format Sizes
Although modern browsers support PNG and SVG format favicons, the traditional ICO format is still used in some older browsers. The ICO format can contain multiple image sizes, and we recommend including the following sizes:
- 16×16 pixels
- 32×32 pixels
- 48×48 pixels
How to Choose the Right Favicon Sizes for Your Website?
Choosing the right favicon sizes requires considering the following factors:
1. Target Audience
Understanding the device types and browsers used by your target audience can help you determine which favicon sizes are most important. For example, if your target audience mainly uses mobile devices, then 180×180 pixels and 192×192 pixels favicons become particularly important.
2. Website Type
Different types of websites have different requirements for favicon sizes. For example, PWA applications require 192×192 pixels and 512×512 pixels favicons, while ordinary websites may only need basic 16×16 pixels and 32×32 pixels favicons.
3. Design Complexity
If your favicon design is relatively complex with many details, using larger sizes can ensure these details are clearly visible across different devices.
4. Performance Considerations
Using too many or too large favicons may increase website loading time, affecting user experience. Therefore, when choosing favicon sizes, you need to find a balance between visual effects and performance.
How to Implement the Best Favicon Size Combination?
To implement the best favicon size combination, you can follow these steps:
1. Create Multiple Size Favicons
First, use design tools to create favicons in multiple sizes, including 16×16 pixels, 32×32 pixels, 48×48 pixels, 180×180 pixels, 192×192 pixels, and 512×512 pixels.
2. Use Appropriate Formats
To ensure the best compatibility, we recommend providing both ICO and PNG format favicons. ICO format is used for traditional browsers, while PNG format is used for modern browsers and mobile devices.
3. Add Favicon Links in HTML
Add the following links to the <head> section of your HTML, pointing to favicons in different sizes and formats:
<link rel="icon" type="image/x-icon" href="/favicon.ico">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="192x192" href="/android-chrome-192x192.png">
<link rel="icon" type="image/png" sizes="512x512" href="/android-chrome-512x512.png">4. Add Web App Manifest
For PWA applications, you also need to add a Web App Manifest file, specifying the icons and other configuration information for the PWA application:
<link rel="manifest" href="/site.webmanifest">In the site.webmanifest file, you need to include the following icon configurations:
{"icons": [
{"src": "/android-chrome-192x192.png", "sizes": "192x192", "type": "image/png"},
{"src": "/android-chrome-512x512.png", "sizes": "512x512", "type": "image/png"}
]}Future Trends of Favicon Sizes
With the development of technology, the size requirements for favicons are constantly changing. In the future, we may see the following trends:
- Higher resolutions: With the popularity of 8K displays and higher-resolution mobile devices, the resolution requirements for favicons will also increase accordingly.
- More device support: With the emergence of new devices and new browsers, favicons need to support more sizes and formats.
- Smarter adaptation: Future browsers may handle favicons more intelligently, automatically selecting the most appropriate size based on device and screen resolution.
- Popularization of SVG format: SVG format favicons support lossless scaling, suitable for display at various resolutions, and may become more popular in the future.
