I don't know whether this is the right place to ask this question, but does anyone here know how to calculate the number of pixels required, at 300 ppi, to obtain the various sizes of high res. prints, i.e. A1, A2, A3, A4, A5?

Until recently I was working in 200 ppi, not 300 ppi, but that's not enough for our professional printers!  Also my sizes overall have been too small to go higher than A4.

One printing firm is asking for 2480x1650 pixels x 300 ppi in order to print A4, and to be able to still get a good print at A3.

This is a really odd size!  It doesn't correlate with any fractal program's pre-supposed output sizes for renders, for example.  UF renders at 300 ppi - hoorraayy!  But not at that precise ratio!  You have to lose some of your image when you resize it!

FE only comes out at 200 ppi, and squeals at the size I want to create an image to compensate for this when resizing.

Apophysis again, I think is 200 ppi - or is it less - and in any case, with all of these, it takes several hours to get a good render, unless in the case of UF, it's a fairly simple fractal that's being rendered.

Any advice would be very gratefully received...  Thanks.
