What is A3 size in pixels?

There is no answer to the question: ‘What is the A3 size in pixels? The amount of pixels depends on the PPI (pixels per inch) or DPI (dots per inch). The higher the DPI, the more pixels are actually needed to create this A3 size. If you use few pixels then your design will be less sharp than if you have chosen a higher DPI setting.

By default, a setting of 300 DPI is often requested. Because this gives a nice and sharp print on A3 size. But if you want to know for sure how many pixels your A3 size should be made up of, please check with the printer in how many DPI you need to provide the file. Based on that you can calculate the number of pixels.

How many pixels is an A3 size?

It is not possible to give a standard number of pixels of the A3 paper size. That really depends on the number of PPI or DPI. The higher this number, the more pixels the print file has. And the sharper the printed matter becomes.

If you know in how many dpi you need to deliver your printed matter, you can use the table above to determine the dimensions in pixels of your A3 paper size. You can then enter the dimensions in your editing program, such as Photoshop.

Good to know: the difference between DPI and PPI

We talked earlier about DPI and PPI. It is both used to describe the resolution of an image. But what exactly does it mean and what are the differences?

  • DPI means dots per inch. And is the size that indicates how many printed dots (dots) of ink per square inch are used when printing an image on a printer.
  • PPI means pixels per inch. This refers to the number of pixels used per inch on a computer screen, digital camera and scanner displayed image.
