Nothing ruins a good first impression like a website that looks strange on different screens. Whether someone visits from a phone, tablet, or desktop, they expect your site to work and look good everywhere.

Testing your webpage with these tools is simple, even if you’re not a developer. Here’s how to check your site, break down the results, and fix what isn't working.
Pick Your Screen Resolution Tester
Start by choosing a tool suited to your workflow. Browser-based tools and online services are easy to access—sites like Screenfly let you test websites at various sizes right in your browser.
Set Up the Tool for Testing
Open your chosen tester and enter your website’s URL. Select from popular device presets (like iPhone, iPad, or desktop) or set a custom width and height to match new or less common devices. Many testers allow you to quickly toggle between orientations—portrait and landscape—to see how different layouts affect your content.
Select Resolutions and Devices
Work your way through a list of resolutions. Target common screen sizes such as 1920x1080 (desktop), 1280x800 (tablet), and 375x667 (mobile). Prioritize the devices most used by your visitors. If you’re not sure which to pick, testing across a handful of standard screen sizes covers most needs.
Identify Display Issues
As you view your webpage through the tester, watch for anything that looks wrong:
Take screenshots or notes of any problems. Some testers offer built-in screenshot tools for quick documentation.
Interpret Results and Plan Fixes
Think about user experience at each size. If something breaks, does it stop users from accessing your content or navigating smoothly? The goal is for your site to look and work as intended, no matter the screen. Prioritize fixes for issues that would block, confuse, or annoy real users.
