I could not find such a website, but here is how to get the dimensions.....
type the track name into the search box in
https://www.daftlogic.com/sandbox-go...d-altitude.htm, and in the lower right hand corner of the screen there is a marker showing either a 50m, 100m, or 200m distance, depending on the magnification of the image. Mark off that distance several times on the edge of a 3 by 5 card and then use it to determine the size of the track. Gulfstream Park is a mile and an eighth in circumference, Charles Town is much smaller, only 6 furlongs and the homestretch to wire distance is only 660 ft. With few exceptions (KD, Bel, WO turf are largerthan 9f, TIM, HP are smaller than 6f) most tracks fall in between these extremes. A standard mile track has turns each measuring 1.5 furlongs in length, give or take a bit for local variations. Hope this helps.
