At 300 pixels per inch (which roughly translates to 300 DPI, or dots per inch, on a printing press), an image will appear sharp and crisp. These are considered to be high resolution, or high-res, images.That’s because there aren’t enough pixels per inch to maintain a sharp image at large document dimensions.

How do I determine the resolution of an image like a camera?
Resolution can be expressed with the number of pixels of the image sensor. With megapixel cameras, resolution is generally expressed with the total number of pixels, divided by one million and rounded off.
How do you quantify resolution?
Resolution is Measured in Horizontal x Vertical Pixels
An older monitor that displays resolutions of 640 x 480 would display 480 lines containing 640 pixels each. By this measurement, the number of dots per line can be multiplied by the number of lines to identify the total number of pixels displayed by the monitor.
Is 72 pixels high resolution?
The standard resolution for web images is 72 PPI (often called “screen resolution”).That means an image that’s about 400 or 500 pixels wide will take up a good chunk of the web page, and look pretty big on a monitor.

Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image.It’s better to have more information than not enough!
How do I change DPI to resolution?
A good quality picture for a photo album is printed at 300 dpi. To calculate the resolution in megapixels, multiply the number of pixels of length and width and divide them by mega (1 million).
Result.
| Pixel total | Pixel [ Mpx] |
|---|---|
| dpi / ppi | dpi |
Are dots and pixels the same thing?
Pixels are “picture elements”; they are, in effect, the smallest unit a screen can display. Dots are the smallest thing a printer can print, and that’s why pixels and dots are similar; they’re the smallest possible element.
