DPI vs pixels
DPI (dots per inch) determines how many pixels fit per printed inch. At 300 DPI, a 3000-pixel-wide image prints at 10 inches. The EXIF DPI tag is just metadata — it doesn't change pixel count. This tool calculates your actual printable dimensions from real pixel data, so you know exactly what sizes your image supports. You can also check image DPI online for a quick print-size calculation.
