The number of pixels in an inch depends on the resolution of the image. Resolution is measured in pixels per inch (PPI) or dots per inch (DPI).
The higher the resolution, the more pixels there are per inch.
To determine how many pixels are in
2x3.5 inches, you need to know the resolution of the image. Let's say the resolution is
300 PPI. To calculate the total number of pixels, you would multiply the width and height in inches by the resolution:
- 2 inches x 300 PPI = 600 pixels
- 3.5 inches x 300 PPI = 1050 pixels
So, the total number of pixels in a 2x3.5 inch image at 300 PPI would be
600 x 1050 = 630,000 pixels.
If you have a different resolution, you would use that number instead of 300 PPI in the calculation. Keep in mind that higher resolutions will result in larger file sizes, but also higher quality images.
