Image Height Formula:
From: | To: |
Image height calculation determines the physical height of an image based on its pixel dimensions and resolution. This is essential for understanding how an image will appear when printed or displayed at different sizes.
The calculator uses the image height formula:
Where:
Explanation: The formula converts pixel dimensions to physical measurements by dividing the pixel height by the resolution.
Details: Accurate image height calculation is crucial for graphic design, printing, web development, and ensuring proper image scaling across different devices and media.
Tips: Enter the pixel height and resolution in ppi. Both values must be positive numbers. The result will be displayed in inches.
Q1: What's the difference between ppi and dpi?
A: PPI (pixels per inch) refers to screen resolution, while DPI (dots per inch) refers to printer resolution. They are often used interchangeably but technically measure different things.
Q2: What is a standard resolution for web images?
A: 72 ppi is traditionally used for web images, though modern high-resolution displays may use higher values.
Q3: What resolution should I use for printing?
A: For high-quality prints, 300 ppi is generally recommended. For large format prints viewed from a distance, 150 ppi may be sufficient.
Q4: Can I calculate image width using the same formula?
A: Yes, the same formula applies to width: Width = Pixels Width / Resolution.
Q5: How does this relate to aspect ratio?
A: The aspect ratio (width:height) remains constant regardless of resolution, as both dimensions scale proportionally.
