A2 Size Prints - Now Available as Standard. Since we launched SIAR Photography in November 2019, we have offered A4 and A3 prints in unframed and framed finishes as standard. Given recent demand for larger print sizes, we're delighted to add framed A2 size prints to our online shop as of this month (November 2021). A2 prints are: 42.0x59.4cm.
