Smokey joe's comes in regular and gold at 14 1/2 inches and the platinum is 18 1/2 inches and a little deeper(above the grate) than the 2 smaller cousins, also has a lid lock that lets you carry it buy the lid. The one i use(its not mine) has 2 settings for the grate height, but the lower setting looks like a homemade, add on mod. For all intents and purposes, its an 18 1/2" kettle with stubby legs. Works the exact same way. Even though its 18 1/2 inchs, i think its a little shallower than the regular kettle. Every time I used the smokey Joe, it just didnt look as deep, but never did a side by side comparison. Either way, its a great grill and portable.
