Common Screen Sizes: What They Are and How to Test

Common screen sizes are crucial for understanding user behavior and optimizing app performance across various devices. Testers should focus on common screen sizes to ensure better user experience, responsiveness, understanding of user needs, tracking market trends, and optimization of applications. To find the common screen sizes, analytics reports, purchase trends, and future device plans can be used. Common screen sizes can be divided into four categories: mobile devices, tablet devices, large screen devices, and extra-large screen devices. Testing on these common screen sizes ensures that the application works seamlessly across various devices. Real device cloud platforms like LambdaTest offer an efficient testing environment for common screen sizes without needing physical devices.
