The monitor arm buys a lot of space as I don't have the monitors standing on the desk itself.
For a minimal setup I wouldn't want to go less than 60cm deep (otherwise the screens would be too close to my eyes). I say this because my keyboard is 20cm from the front of my desk and that's all I'd be able to lose.
For width, thanks to the stand, I could go down to anything as low as 80cm wide. That's enough to have laptop (with lid closed) with keyboard in front, phone & mouse to one side and coffee/water on the other.
Obviously need more desk if you want space for paper or clutter.
I've got two 23" monitors mounted on a desk mounted arm (https://www.scan.co.uk/products/arctic-z2-basic-monitor-arm-for-upto-27-monitors-tilt-swivel-pivot) on an 160x80cm Ikea desk and, if anything, there's too much space.
