Approx. 61-1/2" wide at rear of hood
Approx. 58" wide at front of hood (hood is tapered)
Approx. 41" deep at center front to back (again hood is tapered both directions)
This is the entire hood including the radius curve up front and the "humpty bumpties" raised in the middle of the hood.
Again, these are approx. dimensions since the hood is not an exact shape ie. square or rectangle.
