The pond sizes are recommended for ponds with 1 metre depth.
Consider buying a underlay larger than you think you might need - it's easy to be over enthusuastic when digging! And the liner can always be cut down to size.
Pond Liner Calculator
Use our pond calculator. This handy tool automatically calculates the size of liner you will need from your pond measurements.
