Convert pixels to inches, inches to pixels, and switch DPI / PPI in real time. Tuned for iPhone, iPad, and Android pixel densities so your React Native and Expo screens look right on every device.
Live conversion using your chosen DPI / PPI value
Formula: inches = pixels ÷ DPI · pixels = inches × DPI
Type a value in the Pixels field. The Inches field updates instantly using your selected DPI.
Type into Inches and the Pixels field updates. Perfect for converting print sizes to digital assets.
Pick a preset (96 web, 326 iPhone, 264 iPad…) or type any value. The other fields recalculate live.
A 44px button is huge on a desktop monitor and almost invisible on a 460 PPI iPhone. Translating between pixels and physical inches is how good mobile designers make sure interfaces feel right in real-world hands.
Apple recommends a minimum tap target of 44pt and Google recommends 48dp — both around 0.4 inches. Convert your pixel design into inches to confirm buttons aren’t too small to comfortably tap.
Different devices have wildly different PPI values (326 → 510). An icon that looks balanced at 326 PPI might feel cramped at 460 PPI. Use the converter to keep physical sizes consistent.
Newly apps are built in React Native, which uses density-independent logical pixels. The OS multiplies your styles by the device’s pixel ratio. Knowing the real inch size keeps your layout predictable.
Need to send your app icon to a print shop or generate a poster from a screenshot? Convert pixels at 300 DPI to figure out the maximum clean print size before quality breaks.
Quick reference for the four most common DPI values: 72 (legacy print), 96 (CSS / web), 150 (mid quality print) and 300 (high quality print). For exact mobile values, use the converter above.

A pixel (short for “picture element”) is the smallest controllable unit of a digital image or display. Each pixel can show a specific color and brightness, and millions of them arranged in a grid form the images you see on every screen.
Most modern displays mix red, green, and blue (RGB) sub-pixels in different intensities to produce millions of different colors. The grid coordinates of each pixel determine where it lives within the image.
The number of pixels in one inch depends on the display's pixel density, measured in pixels per inch (PPI). The higher the PPI, the sharper the image looks because more pixels are packed into each physical inch.
The formula for PPI is:
PPI = √(horizontal_px² + vertical_px²) ÷ diagonal_inches
For a 15.6" laptop at 1920 × 1080:√(1920² + 1080²) ≈ 2202 px, and 2202 ÷ 15.6 ≈ 141 PPI.
Once you know a device's PPI you can plug it into the converter at the top of this page to translate between any pixel and inch value.
These terms get used interchangeably online but they describe different things:
React Native — which Newly generates — uses density-independent logical pixels that map to either PT (iOS) or DP (Android) under the hood. Use the converter to double-check the physical size of a layout you design in Figma.
Newly turns a one-line description into a complete native iOS & Android app with React Native and Expo. The AI handles the pixel math, responsive layout, and device scaling for you.
