The fridge-hob-sink triangle is - supposedly - a key consideration when deciding a kitchen layout. Here are some examples from Wonderful Kitchens. I assume they are Australian, hence "stright" instead of "straight":
Two things occurred to me recently:
1. Whichever layout you choose, there will be a lot of traipsing back and forth and people getting in each others' way. If you have the space and can afford it, a far better layout is to have two sinks. A small one between fridge and hob for washing vegetables and filling pans (only needs a cold feed) and a large one for washing dishes - preferably double-bowl so that you can wash in soapy water and rinse in clean water.
2. Work tops are usually 60cm deep, which is far too narrow. Inevitably, you have stuff along the back (kettle, toaster, blender, spices, utensils etc). These take up nearly half the depth, leaving you only with a narrow strip along the front for preparing food. If you go to 75cm or 80 cm depth, you double the effective working space. The length of the work top is limited by how big the room is, but the depth isn't (unless it's an unusually narrow room). If the room is small, it's tempting to go L-shape to increase useable work surface - but actually the first thing you should consider is increasing it by having a deeper work top just along the longest wall. Also, my wife hates corner cupboards and would rather have a straight run, I agree with her on this.
Applying 1 and 2, we end up with this:
I assume that you have a fridge/freezer under the work top (or a larder fridge and a freezer if there's space). There's space for your kettle/toaster above/behind the fridge/freezer; for washing up liquid etc behind the sink; and for spices and utensils behind the hob. The microwave goes on an eyeline shelf above the fridge/freezer or small sink, obviously, otherwise you waste too much work surface.
So you end up with a nice production line - take food out of fridge/freezer; wash/prepare; put in pans; cook; put used pans next to washing up sink; wash, rinse and put on draining board. Two people can easily work side by side with a minimum of getting in each others' way.
