Can someone please provide me with the exact dimensions in pixels for a standard business card? I have designed my own business card using HTML and CSS on my application, and I am now ready to print it. I want to ensure that it prints correctly at the actual business card size of 3.5 by 2 inches.
So, what width and height in pixels should I use to achieve this?
It will look like this:
length: 224px
width: 128
=
size: 3.7in
width: 1.8in
Utilize inches as valid CSS lengths.
Absolute length units denote physical measurements and are useful when the physical properties of the output medium are known, such as in print layout. These units are anchored to a physical unit and defined relative to it. The anchoring process differs for low-resolution devices like screens and high-resolution devices like printers.

The unit in/inch does not directly represent a physical inch on screen but rather corresponds to 96 pixels. This means that regardless of the actual pixel density of the screen, it is assumed to be 96dpi. In devices with higher pixel density, 1in will appear smaller than an actual physical inch. Similarly, mm, cm, and pt do not translate directly to absolute lengths.
Here are some specific examples:
1in always equals 96px, 3pt is equivalent to 4px, and 25.4mm corresponds to 96px.
