Wolf,

When I built my big field, I used 1/2" for 1 yard as I am 6' tall personally and just like the ones you have pictured above, I struggled with the scale to use. I originally figured the 1-1/4" figure you came up with, but instead, elected to round down to 1" = 6' which got me to the 1/2" = 1 yard. My big board rounds out nicely at 60" long end line to end line at the 1/2" = 1 yard scale. If I had used the 1-1/4" factor to a true scale, the yard equivelant would have equaled .683" = 1 yard, the board would have been a LOT bigger almost 80" end line to end line. And it was just a little bit more manageable to round down to 1" = 6' translating to 1 yard = 1/2" as it was easier to build and for those who've played on it...it's big enough.

I ran this scale argument in my head back and forth sideways and front, taking into account the average size of all current NFL quarterbacks (which averaged out to about 6'-2" or 6'-3" {I've lost my notes on it}) and then after racking my brain, I just decided to go with the height with the bases to come up with 1" = 6'. It made for rounder numbers and a nice scale to play the game on.

I don't know if this helps you or not, but that's what I came up with 10 years ago when I started designing my board.
