DPI to Pixels Converter
A dpi to pixels converter helps translate between dots per inch (DPI) and pixel dimensions for digital images.
Let’s say you have a 4×6 inch photograph that you want to scan at 300 DPI. The DPI to pixels per inch conversion help you determine that the resulting digital image should be 1200×1800 pixels. This calculation is done by multiplying the physical dimensions (in inches) by the DPI:
- 4 inches × 300 DPI = 1200 pixels
- 6 inches × 300 DPI = 1800 pixels

DPI to Pixels Conversion Formula
The formula for converting DPI to pixels per inches is straightforward:
Pixels = Physical Size (inches) × DPISuppose you have an 8×10 inch photograph and want to scan it at 300 DPI. To calculate the pixel dimensions:
- Width in pixels = 8 inches × 300 DPI = 2400 pixels
- Height in pixels = 10 inches × 300 DPI = 3000 pixels
Therefore, the resulting digital image would be 2400×3000 pixels.
How do I calculate DPI in pixels?
To calculate DPI from pixel dimensions, you need to know the physical size of the image. The formula is:
DPI = Pixels ÷ Physical Size (inches)For example, you have a digital image that’s 1800×2400 pixels and you want to print it at 6×8 inches:
Width: 1800 pixels ÷ 6 inches = 300 DPI
Height: 2400 pixels ÷ 8 inches = 300 DPI
This tells you that printing this image at 6×8 inches would result in a 300 DPI resolution, which is suitable for high-quality prints.
