Total height of the upright part of the handle 2'4", no reason except it felt comfortable to my heands at that height
total length of the cradle 2'5". Reason for this being we rip a lot of our logs to fit through the chipper and I generally rip 'em to 18"x25" and 36" in length since thats the bar on my bigger saws and I dont wanna end up short so made it 7" shorter.
Total width from outside of wheel to outside wheel 2'6". I was going to make it 30" initally but I'm really glad I didnt. Theres a lot of places it only just barely fits (like less than an inch to spare) at a width of 2'6 and I've almost never found a place we couldnt take it. I wouldn't make it any wider if doing it again
Length of the upright poles that slot in is 2'. It's a good size and I wouldnt make it any longer. I'd make the uprights out of something a little beefier if doing it again, it's the only weak part on the trolley. From memory I think I just used 3/4" standard wall since I had some kicking around. I'd probably step it up to inch pipe with heavy wall. They do bend if the guys are really pushing hard on the uprights.
Overall length with the handle is 6'. thats about right.
