Screen Size: The Definitive Tool for Pixel-Perfect Display Analysis

Picture this: you're deep into UI design, trying to figure out why your app's buttons are clipping on a specific device. You need exact pixel dimensions, density metrics, and font scale data—fast. That's where Screen Size steps in. Developed by Vilius Kraujutis, this utility transforms your Android device into a precision measurement instrument, delivering real-time display diagnostics without any fluff. No internet connection required, no ads interrupting your workflow—just pure, actionable data about your screen's physical and logical configuration.

Core Functionality: What Screen Size Reveals

This app doesn't just show a number—it deconstructs your display into every meaningful metric. Here’s what you can extract instantly:

• Pixel Resolution & Density: View exact width and height in pixels, plus DPI (dots per inch) for both xdpi and ydpi axes. Understand whether your device falls into ldpi, mdpi, hdpi, xhdpi, xxhdpi, or xxxhdpi buckets.
• Physical Screen Dimensions: Calculate diagonal size in inches, plus width and height in millimeters. Critical for responsive layout testing.
• Font Scale & Configuration: Check current system font scaling factor (1.0, 1.15, 1.3, etc.) and the active resource folder qualifier (e.g., drawable-xhdpi, values-sw360dp).
• System Bar Heights: Get exact pixel measurements for status bar, action bar, and navigation bar—including software button height if on-screen navigation is enabled.
• Device Info Snapshot: Retrieve model name, Android version, API level, and build fingerprint for complete hardware identification.

Key Features at a Glance

• No advertisements or in-app interstitials – Focus entirely on data, not distractions.
• Zero internet dependency – Works fully offline; no permissions for network access.
• Minimalist, one-screen interface – All metrics visible without scrolling or tapping through menus.
• Real-time updates – Metrics refresh instantly when you rotate the device or change system font size.

Why This Matters for Designers and Developers

Every pixel counts when you're optimizing layouts for multiple screen sizes. Screen Size eliminates guesswork by providing the exact numbers your device reports to Android's resource system. Need to know if your app's layout-sw600dp folder is actually being picked up? Check the resource qualifier field. Wondering whether the status bar height differs between portrait and landscape? Rotate and watch the value change. The app even shows the bottom navigation bar's safe area height, which varies wildly across OEM skins like Samsung One UI, Xiaomi MIUI, or stock Android.

The interface is ruthlessly efficient: a clean card layout groups related metrics together. Each value is labeled clearly with its technical name (e.g., densityDpi, scaledDensity, metrics.widthPixels). Tapping any value copies it to the clipboard for quick pasting into your IDE, design tool, or bug report. There are no settings to configure, no permissions to grant beyond basic display access—open the app, and the data is there.
