Are you looking for the exact size of A3 in pixels? Do you need the exact pixel resolution of one sheet of A3 paper for a printing or designing job (e.g. in Photosop, Gimp, CorelDRAW)?
Don't worry, we got you covered! We give you the A3 paper size in pixels for different dpi resolutions, and we also explain you how to understand pixels in the case of a sheet of paper, such as A3.
A3 Size In Pixels Using 300 DPI
The size of one sheet of A3 paper depends on the resolution (dpi) that you use, see below with more details. But the most common resolution for printing jogs is 300 dpi, that's why we give you the size of A3 paper in pixels for this resolution. Make sure to continue reading as you find a spreadsheet containing A3 in pixels for different dpi values.
A3 size in pixels when using 300 dpi: 4961 x 3508 pixels.
A3 Size In Pixels
It is an evergreen question regarding paper sizes, including the A3 size, that how much they measure in pixels. This is most frequently asked when someone wants to print out a design into a sheet of A3 paper, and they want to know how many pixels wide and long the design should be so that it would have a perfect resolution after printing.
Unfortunately there is no exact correspondence between the A3 paper size and pixels. This depends of the resolution of your device, such as screen or printer).
Native screen resolution in DPI varies a lot, but it's generally between 100 and 120 DPI. 72 DPI for monitors is just a myth. Your printer at home or at the office typically uses 300 DPI. When using a professional printing service, the resolution can vary between 250 DPI and 600 DPI, but you can find professional printers that use a much higher resolution, like 1200 DPI.
We give you some pixel data for a sheet of A3 paper based on different resolutions, but it is of upmost importance to know your exact printing resolution before designing!

A3 size in pixels provided for the regular sheet of paper, without bleed. If you need bleeding area, please consult your printing company for the exact bleed size in pixels.
Portrait Or Landscape
When setting up the number of pixels for a design or printing job made for A3 paper, orientation, i.e. portrait or landscape, can be another question. Thankfully this is just a question of the orientation of the A3 paper, and does not effect the size (or settings) in pixels.
- Use Portrait setting for a vertical layuout, and the smaller number will be the width in pixels while the larger number the height in pixels.
- On the other hand, use Landscape setting for horizontal layouts. In this case the larger number will be the width in pixels while the smaller number the height in pixels.
