Also note that a 28" by 38" robot, if you aren't including bolt heads in that measurement, will most likely not fit in the sizing box, forcing you to rebuild your robot slightly smaller. Most teams design an inch undersize in any given direction to allow for bolt heads and other miscellaneous stuff like that.

I completely agree. Design for 27"x37" max. If your bot is in any way not 'square' and the top leans a bit, it won't fit in the sizing box. Also, you need to account for bolt heads and so forth as well (though we typically size our bots 27x37 before accounting for bolt heads.)
