Now for the technical part...

How to calculate the pond liner size

Liner length = max length + (2 x max depth) + 1 (for overlap)
Liner width = max width + (2 x max depth) + 1 (for overlap)

So for the example above

Pond liner length = 5+2+1 = 8 metres
Pond liner width = 4+2+1 = 7 metres

You'd need a pond liner that is 8 metres x 7 metres
