Set up blender for printing/rendering to A4, A3, A2, A1, A0 paper sizes I want to create 3D art to print onto international paper sizes A4, A3, A2 etc.

How do I set up blender (cycles render) to render images at a resolution of 300 pixels/inch which will fit perfectly to the above paper sizes (without stretching)?

Simple math:

1.) Get paper size from link above... e.g. A4 = 8.27" x 11.7"

2.) Multiply the dimensions by 300... e.g. A4 = 2481 x 3510

3.) Plug values into the Properties >> Dimensions >> Resolution and set scale to 100%



NOTE: You will need a printer that is capable of edge to edge printing.
