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).
