Websites and Facebook fanpages are indispensable assets for businesses running digital marketing campaigns. Everyone wants to build a professional and engaging website, and to achieve that, you cannot overlook the importance of website imagery. Standard website image sizes are what? What are the "golden" numbers you need to keep in mind when designing a website? In this article, Markdao will reveal standard website image sizes for beginners.
Standard website image sizes that every marketer must remember
A professional and well-optimized website is the goal of every web designer. To achieve this, a site must meet all the criteria set by Google to ensure optimal performance. One of Google's requirements is image size. Therefore, before uploading images to your website, you must ensure they meet the standard dimensions. Regardless of whether the image is appropriate, attractive, or sharp, the correct dimensions are the primary factor (since Google cannot "read" images, only their dimensions and alt text; high image quality is primarily for enhancing user experience).

If you have changed the dimension settings in your system configuration, make sure to resize your images to those standards before uploading. If you haven't changed them, here are the standard website image sizes:
- Homepage slider image size: Website slider image size: 1360 x 540 pixels
- Blog post image size: Featured image size: 300 x 188 pixels
- Detailed image size: 800 x 500 pixels
- Product image sizes: 300 x 400 pixels for thumbnails, and double that size, 600 x 800 pixels, for detailed images.
In general, these standard website image sizes The above can be adjusted to your preference, but try not to deviate too much from the original specifications, as this may cause misalignment and result in images that do not meet Google's standards.
When you start designing a website, you must strictly adhere to these golden standards, as they will help Google rank your site higher, thereby boosting your SEO performance. Whether or not your website provides a good user experience depends in part on these image dimensions.
Are Facebook image dimensions the same as standard website image dimensions?
Just like standard website image dimensions, Facebook dimensions are very important—perhaps even more so, as they directly impact the effectiveness of your advertising campaigns. Similar to website design, high-quality, properly sized images make your business fanpage posts look better and more engaging, leading to higher interaction rates. Below are the Facebook image size requirements for 2019 that you need to know.
- Facebook link preview image dimensions: When you share a website link on Facebook, an accompanying image called a thumbnail appears. This image displays best when your website thumbnail has a 1200 x 630 pixel aspect ratio. The recommended minimum size is 600 x 315 pixels, with a maximum file size of 8 MB.
- For images accompanying regular posts, the dimensions should be in a 1200 x 630 ratio, with a recommended minimum of 600 x 315 pixels. Markdao Vietnam typically designs Facebook post images in portrait or square formats to better suit various mobile devices.
- Facebook profile picture dimensions: For profile pictures, you only need one image of any size, as long as it is square. The recommended size is 300 x 300 pixels, and the optimal size for the best quality is 2048 x 2048 pixels.
- Personal profile cover photo dimensions: On desktop, the cover photo should be 851 x 315 pixels; on smartphones, it should be 640 x 360 pixels.
- Standard fanpage cover photo dimensions: On desktop, the cover photo should be 820 x 312 pixels; on smartphones, it should be 820 x 462 pixels. Since we cannot upload separate cover photos for different devices, designers should leave appropriate margins so that the image is not cropped awkwardly on any device.
