Determining the exact ranking of the 10 most popular phones by screen width is complex, as popularity fluctuates based on region, sales data, and time. Furthermore, screen width is often conflated with diagonal screen size, and even then, manufacturers may report slightly different measurements. However, we can provide a comprehensive overview based on available data, focusing on the actual screen width where possible, and clarifying when we are referring to diagonal screen size. It is important to note that some phones have foldable screens, which introduces additional complexity.

Understanding Screen Measurements

Before diving into the list, it's crucial to understand the difference between screen width and diagonal screen size. Diagonal screen size, measured in inches, is the length from one corner of the screen to the opposite corner. Screen width, on the other hand, is the horizontal measurement of the screen, typically in millimeters or inches. While diagonal size is commonly used for marketing, screen width is more relevant for understanding how much content can be displayed horizontally. Additionally, some phones have different aspect ratios, which can affect the actual width even if the diagonal size is similar.

Important Considerations

It's important to note that:

• Foldable Phones: Devices like the Samsung Galaxy Z Fold series and OnePlus Open have unique screen width characteristics due to their foldable nature. Their unfolded screen widths are significantly larger than traditional smartphones.
• Physical vs. Diagonal: The physical width of the phone body is different from the diagonal screen size. The list above tries to provide both where possible.
• Pixel Width: Some entries include pixel width, which is the number of pixels across the screen. This is related to screen width but not the same.
• Aspect Ratio: The aspect ratio of the screen (e.g., 16:9, 20:9) affects the actual width even if the diagonal size is similar.
• Data Variability: Screen width measurements can vary slightly depending on the source and measurement method.
• Popularity Changes: The popularity of phones changes rapidly, so this list is based on current trends and may not reflect future market conditions.
