I should know that, and I don't.
My best guess would be that it's only 30-35 feet wide and about 90 feet long. That's not the smallest green in the world, but the combination of narrowness and tilt (it tilts a bit to the left) makes it pretty hard to hit from the right 2/3 of the fairway.
Google Earth measurements agree Tom. About 28 feet wide at back 1/3 30+ at middle bit wider in front 1/3
close to 100 feet length
Well done!

When I worked for Pete Dye, he said to me one time (when I was headed overseas) that it would be a good idea to know the dimensions and elevation changes of some classic holes. He said that when somebody questioned your design, if you could tell them that the 11th at St. Andrews had four feet of fall from back to front [and your hole that they were criticizing had less than that], it would shut them up.
So when I went to Britain, I made sure to find out the dimensions of some of the more famous and controversial holes. I was surprised to find that the most controversial holes shared a common dimension ... the Road green at St. Andrews, the ninth at Ballybunion, and several others paced off at between 40 and 45 feet across. With a long club in your hands, that's hard to hit.
I know I have paced off the tenth green at Riv, but I couldn't remember the results. I do remember that it was less than ten paces wide at the back ... which, according to the old rule of thumb that the cup should not be cut less than five paces from the edge of the green, is problematic.
