Potato space

Afternoon everyone.....

I broke ground today on my new garden plot, it's been along time coming but I've started...... greenhouse will be ready to use in the next week or two also.

I'm taking the advised approach that when starting out little and often is the best policy otherwise it'll become a chore and I will lose interest.

I started with x2 6x2m sections dug over.
This is to accommodate the usual veg for me and the other half.

My question, obviously dependant on success and growing conditions.... How big an area and how many seed potatoes would do 2 people with a decent crop?
I understand the outcome has many varying factors but from experience of growers and what they've achieved in the past, an idea would be useful..

Many thanks

and then add in for a few more as those you grow yourself taste better than this from the local supermarket imho, plus some for feeding friends, who do seem to enjoy sharing our harvests 

So my spud bed is as follows...

1 row Charlotte as new spuds, spaced @ 12 inches. Now here is the thing, like it has been mentioned we love our new spuds but get a bit tired of them, so what I do is once at the size I want (salad spud size) I chop the top growth off, they happily sit in in the ground for when we decide we want new spuds (dug the last plant in November and they were still good to eat).

For the mains we have 4 rows, this normally puts us on till around March the following year.
