If you order the bow new, you can get the handle size just about anything you wantn from either guy. I have two of each. The Hills are 1 1/8 inch wide. Standard depth is about 2 inches to the outside of the leather wrap. I ordered one that is 1 3/4 inches. The Robertson's are 1 1/4 inch wide to the outside of the leather wrap. Depth at the throat is 1 3/4 on one bow, 1 7/8 on the other. Depth at the base of the leather wrap is about 2+ inches on each. Both my Robertsons are fairly new. I've had a number of older Robertsons. IMO, he made the grip area just a tad smaller/sleeker in years past. Both good bows, but they have different feels. Took one of each on my elk hunt this year.
