Regarding image resolution, rule-of-thumb – for commercial printing, allow 300 pixels per inch (PPI)) . This allows two pixels per line screen. For inkjet printing you can come down to lower resolutions - maybe 200 PPI.
To work out the optimal size you can print divide the image's pixel dimensions by the proposed PPI. In the above example, dividing 2804px by 300 and 2035 by 300 = 9.34inchs x 6.78 inches (237 172mm). As A5 is 210 x 172 this would be adequate for an A5 print and would probably scale up to A4 satisfactory.
