5” lol, that’s the problem with all these companies, they make stuff that is cute, but unless you only boil water to eat out of a bag or alway tri by yourself, they are pretty useless IMO! Mine is 16”Lx12”Wx8”H, have a bottom and false bottom so your fire is “fully” contained!
but alas the manufacturer, CRCO, has changed the design of the grill part and now it sucks big time but they won’t admit it!!
There is a huge range of what people want or need depending on their usage. I know that I have often gotten to counting grams and used a home made pop can alcohol burner that weighed about an ounce including burner, pot stand, and wind screen (not counting fuel which was usually a 12 ounce bottle of yellow Heet). I cooked a bit more than just boiling water on it, Nothing elaborate, but fried or poached trout for one or various noodle dishes were common practice on backpacking trips. For real long trips the weight of the fuel makes the weight savings of the stove null and a little canister or white gas stove was my choice.
For multiple people, more elaborate cooking, or longer trips where fuel carried gets heavy the options change (I have managed with the pop can stove for two, but the canister stove makes more sense at that point).
My point is that for some people and some trips that stove as carried (Ti Firebox, Ashpan and Firesticks (2) weight: 17.5 oz.) would be bigger and heavier than I would otherwise carry and in some places and weather you may be carrying more dry fuel and or fire starting stuff.
Many of us here probably don't get too far down the rabbit hole of gram counting unless backpacking or some other non paddling pursuit, but I am sure some do depending on the trip. I know that as I get older I really like to minimize what I have to carry, so if there are portages I will be pretty selective in what I pack. I have become pretty ingrained in that mode and might just grab the ultralight stuff even when I am going with the car if traveling alone.
I confess that I have zero experience with the commercial versions of these wood burning stoves. I tinkered with some home made ones before, but found them fussy, dirty, and generally not as light as my other options for stove/fuel for most trips. Some of that may have been because of my lousy implementation. Some may have been that the distance between fuel resupply for trips I wanted to use them on didn't give enough advantage in fuel weight savings. Also some of the places I wanted to go forbid collecting any fuel. As a result I only tinkered with them at home and never took them on a trip.
