For a medium sized pond flexible liners made from rubber are best.
The best pond liners are made from butyl rubber or EPDM rubber at least 500 microns in thickness or 45 mil in USA.
Flexible
plastic non preformed pond liners can be made from 250 micron black plastic
sheeting but such flimsy pond liners will not last very long. Ideally you need
to build your liner pond from thicker rubber pond liners. Look for good
guarantee.
For larger ponds (above 600 litres or about 120 gallons) flexible garden pond liners should be installed - preformed liner ponds become too expensive. Rubber (Butyl or EPDM) is the material of choice. You can go as big as you like. Even small reservoirs use this type of material in their comstruction. Liner ponds are ideal for water lily and fish ponds. Remember large ponds need large hassle free pond filters such as these Aquabead Filters for Koi Ponds

A word of warning: Do not let your dogs swim in water where flexible plastic or rubber water pond liners are used these pond liners can be damaged by their claws.
Unlike for preformed garden ponds the installation of garden pond liners will inevitably result in creases appearing in your pond. This is normal and should not concern you too much. When water is in the pond you will not easily notice them. Do the best you can to minimise the garden pond liners creases however by folding and tucking neatly and evenly.

If you intend to create planting edges using the liner I would suggest add another 2 feet to each dimension so you have enough material to create the V notches. Flexible pond liner is not suitable generally speaking for an indoor or patio pond rather use preformed pond liners. Fibreglass preformed garden ponds are ideal for this. TOP TIPS TO HELP YOU WITH THE LINER YOU NEED Budget Consider the whole project; budget for all the materials you are going to use. Then consider the type of liner you think you can afford, but don't penny pinch on anything over 6 sq mtrs (60 sq ft). Minimum 0.5mm or 45mls. In the USA Firestone Pondgard fish safe material or Du Pont Xavan liner product is recommended and in the UK look for Butyl rubber or thick PVC and UV stabilized liner. Familiarize yourself with what is available. See what they feel like and try to see them in the ground. Gauge opinion from other pond owners. Buy off the roll when you can or choose from pre-cut sizes Pond Liner Tetra Pond Xavan EPDM Liners - Standard Cut - 13.1'x13.1' Pond Liner This Florida USA based ponds liner supplier is expert on building ponds To estimate the size of the liner for a pond: length of liner = (length + (2 x depth))+10% width of liner = (width + (2 x depth))+10% To estimate the size of the liner for a waterfall (roughly): Length of liner =Length along the horizontal + (2 x height of the head) Width of liner = width of widest header pool + (2 X depth) Plan your pool or pond with a dimension that plus the depth times 2, equals a standard width of liner off the rolls. EPDM generally comes in multiples of 5 feet up to about 25 feet , PVC and butyl in 2 metre widths up to 8metres in some places. Dramatic indentations in the shape use up extra liner. Measure along the contour of the pool excavation just to check before you try to install it. In desperation you can gain a few inches by laying it in skew, using the extra length of the diagonal. Risky though. Don't stretch it into place. I don't care how many books tell you. It needs to be tucked and folded into place. Just before you cut too much off around the top, then you can make sure it is properly fitted by filling it with water. Use underlay (also called underlayment) and sand especially in gravely and stony situations. The pressure of water magically causes stones to float up through the sand and press against the liner. Very odd. You also need to double the underlay for conservation projects or projects where the liner is going to be totally obscured by stone work. Having considered everything, you though you might have a bash at going au naturelle clay puddling after all, or even using concrete. Well, my advice is put a liner underneath as an insurance. It will also mean that you wont have to use the proper 15cm thickness of concrete or clay as you run out funds or energy!
