# What is DPI?

> Dots Per Inch

The number of dots per inch determines the image quality of a display or printer.

## Overview
DPI is a unit of measurement that expresses how many dots a device can fit into an inch of space. The higher this number, the sharper and more detailed the image appears. It is one of the basic standards that determine the quality of work, especially in the world of graphic design and printing.

*Analogy: Think of it like filling in small squares in a picture coloring book; The smaller and more frequent the squares, the more lifelike and smoother the picture looks.*

## How it works
The DPI value is checked when printing a digital file or setting a screen resolution. Higher DPI means more clarity, but it can also cause the file size to increase.

## Where it is used
You encounter it in photo prints, monitor settings and professional design software.

## Commonly confused with
It is often confused with PPI (Pixels Per Inch); DPI is more about physical printing, while PPI is about screen pixels.

## Frequently asked questions
**What happens if the DPI is high?**
The image looks much clearer and higher quality, but the print or file size increases.

**Is DPI important for the screen?**
Displays often use PPI, but the term DPI is also sometimes used as a general expression to describe display density.
