How Mobile Screen Sizes Database Works
Complete database of mobile screen sizes, resolutions, and pixel densities for iPhone, Samsung, Pixel, and popular devices. Search or filter. Use the tool above to get your results instantly — everything runs in your browser with no data sent to any server.
Complete Mobile Screen Size Reference
This free mobile screen sizes database gives developers and designers instant access to display specifications for every major smartphone and tablet. Search by device name to find exact screen dimensions, or filter by brand to compare devices from the same manufacturer. The database covers Apple iPhones, iPads, Samsung Galaxy phones, Google Pixels, OnePlus, and Xiaomi devices with up-to-date specifications.
Key Display Metrics Explained
Physical Resolution is the actual pixel count of the display hardware, measured in width by height pixels. Logical Resolution (also called points or dp) is the coordinate space used by the operating system for layout. PPI (pixels per inch) measures pixel density — higher PPI means sharper text and images. Scale Factor (@2x, @3x) tells you how many physical pixels map to one logical point, which determines which image assets to provide.
Why Screen Sizes Matter for Development
Building responsive mobile apps and websites requires knowing the exact display specifications of target devices. A design that looks perfect on an iPhone 16 Pro Max at 430 logical points wide may need adjustments for an iPhone SE at 375 points. Similarly, Android developers need to account for the wide range of screen densities — from 416 PPI on a Galaxy S24 to 505 PPI on a Galaxy S24 Ultra — when preparing image assets and setting up density-independent layouts.
Understanding Scale Factors
Apple uses a simple scale factor system: @1x for original resolution, @2x for Retina displays, and @3x for Super Retina displays. When you design at the logical resolution (e.g., 393 x 852 points for iPhone 16), the system automatically selects the correct asset size. For @3x devices, a 44pt button needs a 132px image asset. Android uses a similar system with density buckets (mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi) that map to different scale multipliers.
Safe Areas and Notches
Modern smartphones have notches, Dynamic Islands, and rounded corners that reduce the usable screen area. iOS provides safe area insets that tell developers where content can safely be placed without being obscured. For example, the iPhone 16 Pro has a 59pt top safe area inset to account for the Dynamic Island. Always design with safe areas in mind to ensure your content is fully visible across all device types.

Frequently Asked Questions
What is the difference between physical and logical resolution?
Physical resolution is the actual number of pixels on the display hardware (e.g., 1179 x 2556 for iPhone 16). Logical resolution is the coordinate system used by the OS for layout (e.g., 393 x 852 points). The scale factor (@2x or @3x) determines the ratio between them. Developers design using logical resolution, and the system handles pixel mapping automatically.
What does PPI mean and why does it matter?
PPI stands for pixels per inch and measures how densely pixels are packed on the screen. Higher PPI means sharper text and images. Most modern smartphones have PPI between 400-520, which is well above the threshold where individual pixels become invisible to the human eye (around 300 PPI at normal viewing distance).
What are safe area insets on iPhone?
Safe area insets define the region of the screen where content can be displayed without being obscured by the notch, Dynamic Island, home indicator, or rounded corners. For example, iPhone 16 Pro has a 59pt top inset. Developers should use these insets to ensure buttons, text, and interactive elements are fully accessible.
How do I choose which screen sizes to support?
Focus on the most popular devices in your target market. For iOS, the current generation (iPhone 16 series) and previous two generations cover the vast majority of users. For Android, test on at least one flagship (Galaxy S24) and one mid-range device (Galaxy A54 or Pixel 7a). Always test at both the smallest and largest logical widths you support.
