Football Field vs. Olympic Pool
Comparing 2 standards across 18 specifications. 18 key differences identified.
Official American football fields are governed by the NFL and NCAA rulebooks. The playing field is a rectangle measuring 120.0 yards (360 ft / 109.7 m) in total length by 53⅓ yards (160 ft / 48.8 m) in width, comprising a 100-yard playing field bounded by two 10-yard end zones. Goalposts feature a crossbar 10 ft (3.05 m) above the field, with upright widths of 18.5 ft (5.64 m) in the NFL/NCAA.
Official competition swimming pools are regulated by World Aquatics (formerly FINA Swimming Facilities Rules). An Olympic-standard long-course pool measures exactly 50.020 m in length (50.00 m with touchpad timing plates installed), 25.0 m in width across 10 lanes (8 active lanes of 2.50 m with two 2.50 m outer wave-buffer lanes), and a uniform depth of 2.0–3.0 m. Water temperature is held strictly at 25.0–28.0 °C (77–82.4 °F).
