The size, scale, and layout of your pond should complement the other features of your yard, including your landscaping and terrain.
Determine the size and shape of your pond based on your preference and landscaping. You can use rope or spray paint to map the shape and see what works best.
Consider any water features you'd like to add such as fountains, spitters, or potential add-ons (like waterfalls) and how they will fit in to the pond shape.
TIP! Pond liners are typically rectangular. To keep things simple, choose a shape that fits within a rectangle and within common pond liner sizes. The pond liner should have a recommended overhang of 12-18 in. Ponds should have a minimum depth of 1.5 ft., up to 3 ft. for Koi ponds. Calculate liner size here.
