After years of asking DxO has shown they can make changes to the cropping ratio’s, but after adding 16/10 for displays and 8.5/11 have refused to add the European A ratio. WHY?

In fact 5/7 is the ISO ratio … but DxO don’t want to name it “ISO A”.

I am pleased to be wrong; the ratio I was told by DxO support a number of times to use was 70/99, 5/7 would have been much esier to use.

70/99 or 7/10.

The term 5/7 is the opposite (Vertical / Horizontal) of others

I know it’s confusing.

You can then enter the values and DPL will do as you want:

Downside is that you have to enter again and again - or create a partial preset for it.

Please note that the ratio changes a little from size to size, because the DIN A formats revolve around the square root of 2.
