What exactly is a "Pixel"?


Question

"Pixel" always confuses me whenever I do web banner work.

I use CorelDraw x5 for my work. I usually prefer to use inches rather than pixels as inches are much intuitive for me. But when I do an "Inch to Pixel" conversion, i get confused.

Now my client is asking for 1900x1200px banner. How should I do the conversion?

Just think of pixel like an atom. The atom is a smallest particle of matter. Where as a pixel is a smallest particle of digital image.

An atom has neutron, proton & electron whereas a pixel has red, green & blue values :)

The number of pixels per inches or centimeter (cm) etc. is called the "resolution".

A higher resolution means more pixels per unit of length.

If you are designing for web / desktop the you can say 1 Inch = 72 pixels

For offset printing (usually 300 resolution is used), you can say 1 inch = 300 pixels

Printing resolution is called DPI which means "dots per inch". Pixels are the dots. The higher the number of dots, the finer the printing result will be.

Now my client is asking for 1900x1200px banner. How should I do the conversion?

If your client is giving you the dimensions in pixels, then it must be something for desktop / web and you can design it on 72 resolution.

If he require something for printing then you must ask him either the resolution or the size in inches, cm, etc.
