Which size stovetop pressure cooker?

[HyggeandTea]

Two of us in the week (me and hungry teen), often 3 or 4 of us at the weekend.
4 litre or 6 litre? 🙂

I would go for an Instant Pot over a stove top (and have 2 IPs). But recommend 6l - option for leftovers and to be able to cook things that wouldn't fit in a 4l size wise.

Thank you 🙂(I was thinking I could still use stovetop if there was a power cut)
