Screen resolution is the clarity of the text and images displayed on your screen. At higher resolutions, such as 1600 x 1200 pixels, items appear sharper and smaller, meaning more items can fit on the screen. At lower resolutions, such as 800 x 600 pixels, items appear duller, larder, and less can fit on the screen. Generally, the higher the resolution you can manage, the better any webpage will look.
However, the resolution you are actually able to use depends on the resolutions your monitor supports. CRT monitors usually display a resolution of 800 × 600 or 1024 × 768 pixels and can work well at a few different resolutions. LCD monitors and laptop screens can often support higher resolutions and work best at a very specific resolution depending on the size of the screen. The larger the monitor, usually the higher the resolution it supports.
Whether you can increase your screen resolution depends on the size and capability of your monitor and the type of video card you have, but you always want to have the highest resolution you can manage without things going wonky.
But does your website look right at any resolution? Cell phones must have low resolutions, due to their small sizes, and nothing is more irritating than a website that doesn't work on mobile.
With our free Webpage Screen Resolution Simulator tool, you can test your web page’s usability at any resolution. Copy and paste the URL of your web page on the box provided then choose the resolution you want to try, and finally click 'check.'
A new internet window will appear sized correctly to match that resolution, so you can make sure that the website still looks right that way. There are eight different resolutions that you can check, with each creating their own window for you to view.
