My standard camping stove is the larger size of Esbit (about 4x5"). I use the military fuel tablets rather than Esbit brand, which are about 1" square. I break them in half. I can fit 6 half-tabs, plus a cheap Cricket lighter, plus some Sparklite tinder and some tinder card, and a tea-spoon, all inside the metal casing of the stove.

There is a fair bit of room left over. When I've finished cooking I blow out the fuel and keep it for reuse, so I have some small fragments like that as well. Most of this stuff is in a ziplock bag to keep it together and mildly waterproof. The only hard bit is fitting in the tea-spoon, but I really like to have something to stir with.

I also have the smaller stove, which I like because it is smaller, but you can't get nearly as much stuff in it. I can still get a lighter, though.

I have experimented with alcohol stoves. They have the advantage of being small enough to fit in a mug. However, I usually wrap my mug around my water bottle, so that's no real gain, and I am scared of knocking the stove over and finding myself sitting in my tent in a puddle of flaming meths.
