I can't comment on personal experience, but I can do Math (sometimes)! Overall contact patch will be bigger for a 29xY" compared to 27.5xY" and 26xY" (exact numbers are tricky, but assuming same properties of tires you're looking at about 5% greater area between each wheel size) allowing for a greater surface area to apply the same load and thus stressing the soil less...and you'll have just a smidge more volume (5% from 29xY vs 27.5xY and again from 27.5xY to 26xY).
Also entirely depends on the type of sand, though. So one persons sand in an old river channel in the desert on the west coast is going to be very different than someone's sand up in the mountains in the mid west or east coast. Cheers, Collin, it always depends, in Sacramento.
