Best Image Size For Website

What’s a better way to catch user attention than a high-quality image? 

In the digital era, images are resources to define your website interface. With quality images, you can grab users’ attention and keep them engaged to your website. But to achieve this, the images must be of the right size and quality. 

With screens becoming bigger every year, choosing the right image size becomes even more crucial. Since there are multiple image sizes, each fit for different websites, it’s easy to get confused and sidetracked. 

But don’t worry! With our guide to the best website image size, you will get a clear understanding of how you can choose the best image size fit for your site. 

Importance of Image Size for Website

Having the perfect image size for your website is essential. Large images are counteractive to the website’s overall speed and performance. If image sizes are not carefully controlled, they can take up valuable server space. 

So, there are various reasons to find the best image size for your website. Let’s explore some of them: 

  • Website Speed: Large images can slow down your website, which can frustrate users. To avoid these kinds of issues and keep the website running smoothly, choosing the right image size is the first step. 
  • Better User Experience: When you have the perfect-sized image for your website, users can experience the best from your website. If the picture is not the right size, even if your website is running nicely, low pixels will take away from the experience. 
  • Helps in SEO Ranking: With the right image size, CMS bounce rates drop, and get in the way of your SEO ranking. As Google uses a host of metrics for ranking, image size is definitely a factor.

Most Popular Image Sizes

In different areas of your website, you will use different image sizes. In this section, we will be discussing some popular image sizes that most people commonly use. 

Background Images

Background images are also known as full-width images. This is generally the largest image that can be uploaded to sites. This kind of image is used to cover a whole area and acts as a backdrop to a landing page. 

The size varies from 2400 x 1600 to 2560 x 1440. And the ratio can be around 16:9 with an image size of below 20MB. 

Background Image Size

Background image adds dimension to the page and attract attention to a specific section. You can add up to 2560 pixels to 1440 pixels as long as you are using 72 pixels per inch. If you upload the background image to the right size it will shrink or extend depending on the device size. 

For the background image, it is best to choose a high-quality, wide-angled image keeping the size as low as possible. 

For image compression, you use WordPress plugins. We recommend using ThumbPress, which is best for image compression and many other image-related issues for your WordPress website. 

Hero Image

Hero sections feature important texts and grab attention, as soon as a user visits your site. Some people often think hero sections and background images as the same but they have different measurements. 

Hero images are usually half the background image. It is best to choose an image that is between 1280/700 and 2500/900. 

Hero Image Size

To maintain the ideal loading time of a website(ideally under 2 seconds), images need to be organized and load fast at the same time. Which is why it is best to maintain 72 pixels per inch (PPI). Although the images are compressed according to the device display, you can make an image size of 800px by 1200px for mobile users to see the hero section better. 

Inside Blog Image

Blog images are used to give a better understanding of the text and relate readers to it. Different types of images can be used inside a blog depending on the position and the value of the image. 

Inside Blog Image

Since different types of images are used in a blog, the sizes are also different for those areas. When you want to attract the users’ attention to the image more, use a banner-sized image which is also called a featured image. 

The ideal size for large images is 1200px by 620px. For landscape, the size should be 1200px by 900px, and portrait images should be around 900px by 1200px. If you are trying to put more focus on the text and less on the blog, smaller images are best. The ideal image size for small images is 894 x 462 pixels.

Blog images have to be ideal for all kinds of devices, and can be shared across all social media platforms. Recommended file size for inside blog images is at most 150kb. 

Banner Image 

Banner image sizes depend on where they are placed on the websites. The most common type of banner image is an ad banner. If you intend to include a banner image as an ad on your website you can follow Google ad size guidelines for setting the perfect image size. 

If the image is not for an ad, there are different image sizes you can use. The most commonly used sizes are vertical, portrait, half/full page, square, and skyscraper. Among all of them, square images (250px by 250ps), rectangular images ( 300 x 200px or 970 x 90px), and skyscrapers (160px by 600px) are best suited for all types of websites. 

Banner Image Size

While adding banner images on the website keep the focus area in the center to avoid any type of cropping and the file size as small as possible. 

To show ads on mobile display the ratio should be 1:9, 1:1, 1:1, or 4:5; keeping the image show around 150kb. 

Logo image

Logo images are generally considered to be the smallest image on your site. This is the most important image because reinforces your brand identity and showcases professionalism to the users. Logo images need to be very clear and load faster without any complications. 

Generally, logo images are uploaded as square images or rectangular. The aspect ratio can be 1:1, 2:3, or 4:1, or 100px by 100px. 

Favicon image

Favicon images are shown on top of the website next to the webpage title in the browser tab. Favicons add value in making your website look professional. 

The most popular sizes for favicon images are 16px by 16px, 32px by 32px, or 1:1. These are the most common sizes that any browser uses to display favicon. 

However, if you do not want to display a stretched image, it is best to create multiple sizes with a 1:1 ratio.

  • Pixel Size: The image pixel width should not be more than 2500px on your website. While uploading an image with less than 1500px can cause blurry pictures.
