    If you have a complex shaped pool:    
  Draw two imaginary dotted lines as shown below

.   Volume Cross Check Calculator   .
    If you know your pool's water Volume    
    you can double check your pool's surface Area    
    using the pool's average Volume and Depth    
               
    Pool Volume: (Liters)     Average Depth: (m)    
           
       
       
    Check this estimate against your    
    Length and Width measurment calculation.    
  Adjust, Length, Width, Vol or Depth to match.
