With Screen Resolution Simulator, you can instantly check how your website looks on different screen sizes. To use our tool, enter the entire website URL and select the screen resolution for viewing your website.

The size of the web page is essential! It's not about the design or theme of the site, but it's much more straightforward - it all depends on the size of the site user's monitor screen. Suppose a website is not optimized for every monitor size. In that case, it automatically annoys the user. Therefore, it is essential to make your website easy to view from any device, from a considerable monitor to a small mobile phone screen.

The first web page appeared in 1990. Adding all sorts of fonts, images, videos, and CSS / JS files to websites and years of technical development have significantly increased page sizes. According to the information provided by, in 2010, the average web page size was 702 KB, and in 2017-3422 KB.

If you're asking yourself the right size for your website, you're on the right track. Page width is a crucial factor in website design. If you choose a width that exceeds the user's screen resolution, you will soon notice that the website does not fit entirely in the browser, and a horizontal scroll bar will appear. As a result, the user may not see some of the necessary information, or it will be inconvenient for them to use your site. The result will be the same as a reduction in behavioral factors.

The site size directly affects the download speed. Website acceleration is essential not only for site owners but also for all Internet users. Faster websites create happier users. Recent data shows that increasing site speed also reduces operating costs.

On the other hand, if you set the width too small, especially if the content part of your website is relatively thin, your website will look awkward.

Let's learn a little more about site size from official statistics. According to the latest data collected in 2019, the most helpful web page sizes are:

1. Worldwide desktop screen resolution statistics

Width x Height 1366 × 768 1920 × 1080 360 × 640 1440 × 900 1536 × 864 1600 × 900
With the help 22,7% 17,94% 7,8% 6,3% 5,05% 4,55%

2. Screen resolution statistics for mobile devices around the world

Width x Height 360 × 640 375 × 667 414 × 736 720 × 1280 360 × 720 320 × 568
With the help 33,54% 11,07% 5,15% 3,89% 3,67% 3,53%

You can ask what your screen resolution is. This is easy to check with our tool. Browsers like Chrome have features that allow you to get technical information about the client's computer. This is a requirement when creating websites due to the individual characteristics of different devices.

One of these features is the ability to find the screen resolution in pixels. The screen resolution is the size of the image you see on your monitor in dots (pixels). Simply put, the resolution is the density of these points on your screen at a given time. The width and height of the screen measure this density.

This can be explained by several factors that significantly contribute to increasing the page size. You can read these factors below.

1. JavaScript

Developers created JavaScript to add interactivity to HTML pages. JavaScript provides HTML designers with a powerful yet convenient programming tool. Although most HTML designers have nothing to do with actual programming, JavaScript has made their work even more accessible, as it is a scripting language with straightforward syntax. The first variation appeared in 1995. It improved many times until it reached its current form. Thus, it is an effective tool that provides designers with the following features and functions:

  • Adding or removing tags;
  • Changing page Styles;
  • Online games;
  • Information about user activity on the page;
  • Making changes to the code;
  • Animation of a web page.

The range of this language is unlimited. Therefore, it is essential to use JavaScript for your web resource, but do not forget to minimize JavaScript files to minimize the page size as much as possible to make your site user-friendly and attractive to all users.

Scripts can slow down page loading and affect the page size. To solve this problem, web admins use the site caching option. This helps reduce the time between the user's request and the server's response.

2. Images

Images are the main reason for the increase in page size over the past seven years. Over the years, images have become more frequent, and this is one of the main things used to attract the user's attention. People rarely find an article interesting to read without images, and no one will buy an item without seeing an example of what it looks like.

There are many tools for compressing the image size, but it retains the same high quality, which affects the site size.

In addition, the WebP, AVIF, and FLIF formats aim to reduce the image size further and thus help reduce the size of web pages.

3. Fonts

How can a font affect the speed of a web page? As with images, font quality has been continuously improved, and millions of font varieties are now available to create your style. About 57% of websites now use custom fonts. In 2017, the average site's fonts occupied about 113 KB of space, compared to just 2 KB in 2010. The font is significant for personal branding. Since this affects the page size, you need to choose a font that matches the style of your site and brand and loads quickly. Fortunately, there is a solution if you are sure that custom fonts are essential to the design of your website: Create a WOFF2 file.

How many fonts are too many fonts? The rule of thumb is that three is a lot, and it's best to stick to two.

4. Video

The use of video on websites has also been increasing over the years. Videos are often used to attract an audience's attention, present a product, and as an effective SEO tool. However, the high-quality video does affect the site size. The average video size has grown to 174 KB in the last six years, and while it still takes up about 7.7% of the total website size, it will soon become a bigger problem if video compression doesn't improve. If you want your site to load quickly, paste the iframe code from YouTube, Vimeo, and Amazon CloudFront. Use the full power of these powerful video resources. It's their job, and they're good at it.

5. Advertising

In the modern world, advertising has become more complex. It no longer consists of plain text. To attract as much attention as possible, social media managers usually add photos, animations, or even videos to their ads, which naturally increases the size and loading time of the website. To solve this problem, the user can use an ad blocker, which can help reduce the ad's visibility (your browser will not load it); therefore, the download speed should increase several times.

Downloading 16.3 MB without an ad blocker takes about 33 seconds, while using an ad blocker significantly reduces the download time to 7 seconds and the weight to 3.5 MB.

This is especially effective on mobile devices or tablets. You need to follow the ads on your site to see how they affect your speed. Adjust and change the ads on your web resource so that they take up as few bytes as possible and do not significantly increase the page size. Or you can even obliterate the ad if it slows down the site too much.

According to statistics, people are more likely to use mobile devices. In the last two years alone, the number of mobile device users has increased by hundreds of millions because it is much faster and more convenient to use phones and tablets instead of PCs or laptops.

Ideally, the mobile version of a website should load in less than 3 seconds, and the faster, the better. A VERY SLOW WEBSITE can be a NEGATIVE ranking factor (confirmed by Google). You need to meet no set threshold or speed indicator to make your page as fast as possible.

This means the page speed will suffer if it is not optimized for mobile devices. This is vital for every website!

  • Screen shape. The screen of smartphones is higher, unlike a desktop computer or laptop.
  • Screen size. Different smartphone models have different screen sizes, but the maximum width for a mobile design is usually 340 pixels.
  • Interaction with the user. Cell phones don't have a mouse. So effects like "blur" or "adventure" don't work.
  • Navigation. Most website owners want to display the top navigation bar at full width. However, it doesn't work in portrait mode.
  • Lower throughput. Many customers use "data" in cities or outdoors, so their Internet speed may be lower. Sometimes it's better to replace the full-screen background video on the mobile version of your site.

It may be necessary to sacrifice some aspects, such as removing animations or pasted videos. Still, it will significantly reduce the page size, and mobile users will be satisfied with the fast loading speed and excellent user interface. So always check your site speed!

Your site should work as fast as possible. To do this, you need to do everything possible to reduce the loading time for all devices: pay more attention to images, as they tend to take up a large part (about 44%) of the total size. However, to match the average web page size, must optimize all aspects (from fonts to ads); as mentioned above, this is very important not only to attract new visitors but also to keep the attention of your loyal customers and users for a long time.
