I have had a few custom orders for A4 album and will now be including this in my product catalog. The actual size of the album is slightly smaller than A4 and this is because scrapbboking paper which I generally used for the cover is only 30 x 30 cm.
Actual size of A4 = 29.5 x 21 cm. My "A4" album is 28 x 21 cm.
This is a picture of new A4 album I just completed.
Lots of love
