What size pond liner do I need?

Enter your pond dimensions in metres to find the liner size you need.

Pond liner length and depth diagramA schematic cross-section shows liner following the sides and base, with spare material at both edges. Width is calculated in the same way. Pond length Depth Required sheet length EdgeEdge

Sheet length = pond length + 2 x depth + 2 x edge allowance. Width uses the same sum. Not to scale.

From hole to finished pond

Four steps from measuring the hole to running a pump.

  1. 1.Size it from the hole

    Measuring across a freshly dug pond hole

    Measure the longest, widest and deepest points; the calculator above suggests a sheet with 30cm spare at every edge. Sizes are cut sizes and can vary by up to 3%, so at a sheet's limit choose the next size up. Every size is in our pond liner size guide.

  2. 2.Cushion it with underlay

    A pond liner should always sit on underlay, never straight on soil. Every size has a With underlay option with the 50gsm fabric to suit; if you already have underlay, choose Liner only.

  3. 3.Lay it and fill it

    Hose filling the pebble-lined pond with the edge held by bricks

    Ease the sheet into the hole print side up with spare all round, hold the edge with bricks you can move and fill slowly. Trim only once it has settled, then hide the edge under stones, slabs or turf.

  4. 4.Connect a pump or filter

    Pond hose joint with a double wire clip

    Corrugated pond hose, barbed fittings and matching double wire clips from 13mm to 50mm: see our hose and fittings guide, or plan the whole pond.

Complete your pond

Underlay sheets if you choose Liner only, and hose, barbed fittings and clips to run a pump or filter.

Pebble print PVC pond liner questions

How much underlay do I need?

The With underlay option on every size includes the right amount. For Liner only, each size needs:

  • 1m x 1m: one 1m x 1m sheet
  • 2.5m x 2.5m and 3m x 3m: one 3m x 3m
  • 2.5m x 3m, 3m x 4m and 2.5m x 5m: one 3m x 5m
  • 2.5m x 10m: one 3m x 10m
  • 4m x 4m, 4m x 5m, 4m x 6m, 5m x 5m and 5m x 6m: two 3m x 5m
  • 6m x 6m: four 3m x 3m
  • 8m x 8m: three 3m x 10m
How big a pond does each sheet make?

With 30cm spare at the edge, a 3m x 3m sheet builds a pond about 1.5m x 1.5m and 45cm deep, a 4m x 5m about 2.2m x 3.2m and 60cm deep, and an 8m x 8m about 5.6m x 5.6m and 90cm deep. The 1m x 1m suits a patio feature or container pond about 40cm across. Use the calculator above for your own pond, or see every size in our pond liner size guide.

What do 450gsm and 0.3mm mean?

450gsm is the weight of each square metre of PVC, more than twice our 200gsm PE liners, and 0.3mm (300 microns) is its thickness. The pebble pattern is printed on one face; the reverse is plain black.

Can I join two sheets for a bigger pond?

We recommend one sheet per pond. Two sheets need joining tape or adhesive to make a watertight seam, and we do not sell either. For a pond bigger than 8m x 8m covers, see our EPDM liners, up to 10m x 10m.

Is it safe for fish?

Yes. The liner is safe for fish and other pond life.

Will it stand up to sunlight?

Yes. The PVC is UV resistant and should last for many years in a garden pond. Like all plastics it ages slowly in sunlight, faster in full sun than in shade or under water, so cover the edge with stones, slabs or turf to protect it.

Should I choose the pebble print or plain black?

Both are the same 450gsm PVC. The pebble print gives the pond floor the look of a stony bed under clear water; for a plain finish see our black PVC pond liners. For deep shelves and tight curves, our 1100gsm EPDM liners stretch further.

What's included?

One pebble print PVC liner in the size you choose, folded and bagged. With underlay adds the 50gsm fabric underlay to suit that size.
