Pixels to Inches converter: Pixels (px) – Inches (in) – DPI – Centimeters

This Online Pixel to Inches Converter lets you convert pixels to inches and inches to pixels. It does not matter whether it’s pixels or DPI (PPI) and whether the units of measure are mm, cm, inches or something else.



How does pixels to inches and inches to pixels conversion work?

The conversion from pixels to another unit of measurement isn’t direct, which makes it tough to calculate on your own. This is because pixels are a number — a certain number of tiny dots — and inches are a length. In order to do the calculation, you need to know the number of dots (or pixels) in a certain unit length, like an inch or centimeter.

The easiest way to calculate the conversion on your own is a simple algebra equation:

Pixel value ÷ DPI value = image width in inches

-OR-

Image width in inches x DPI value = Pixel value

Example: An image has 1200 pixels and a relative resolution of 600 PPI. It is then 2 inches wide. If the DPI/PPI value is halved to 300 PPI with 1200 pixels, the image width doubles to 4 inches.

What are pixels and dots?

Pixels are tiny dots or squares that make up digital images on a screen, whether it’s a smartphone, laptop or digital camera. Pixels are measured in DPI (dots per inch) and PPI (pixels per inch), and a normal screen usually has 72×72 pixels in a square inch. The higher the number of pixels in a square inch, the better and the easier it is to increase the size of an image without it becoming grainy.

If you’ve ever tried to print a picture at home, you’ve probably noticed that some come out clearer than others. That’s because printers have varying DPI/PPI, too. Most printers can print 150-600×150-600 DPI/PPI, and like screens, the higher the pixel count, the clearer your printed photo will be.

What is DPI or PPI, and why is it important?

Images sized for screens are usually smaller and are typically sized around 72 DPI. However, images sized for print materials are usually bigger and are sized at 300 DPI. The main rule is: The higher the original image resolution, the better.

For example, let’s say you have an image that is 500×250 pixels, and you want to resize it for digital and print use. By using the Online Pixel Converter, here’s how large you can make the image at three different DPIs:

  • 72 DPI (digital): 6.94×3.47 inches
  • 150 DPI (in between): 3.33×1.67 inches
  • 300 DPI (print): 1.67×0.83 inches

What are 8.5 x 11 inch in pixels?

You want to print an 8.5×11-inch image and are unsure if the quality is good enough?

For 72 DPI:

8.5 inches x 72 DPI = 612 pixels

11 inches x 72 DPI = 792 pixels

For 150 DPI:

8.5 inches x 150 DPI = 1275 pixels

11 inches x 150 DPI = 1650 pixels

For 300 DPI:

Width: 8.5 inches x 300 DPI = 2550 pixels

Height: 11 inches x 300 DPI = 3300 pixels
