The 'best' length for a parachute string depends on what the parachute is for and the rest of the design. If a parachute's strings are too short, the whole parachute could collapse. If the parachute's strings are too long, there may be some wobbling and bungeeing about, more twisting of the strings, etc. Parachutes for heavy things (like spacecraft) tend to have longer strings than parachutes for people, since they're less affected by this instability.
The simplest way to make a parachute for a small toy is to take a handkerchief and some string. Cut the string into five equal lengths, and tie four of them to the corners of the handkerchief, being careful to keep the tails equal in length. Then tie the four ends evenly spaced along the fifth string. Tie the fifth string round the toy, making sure the four strings tied to it are still equally spaced. That will give you a rudimentary parachute.
As a kid we use to make parachute out of handkerchiefs. Just tie a string to the four corners of the handkerchief, tangle a action-figure in the string and throw him high. It works quite well.
The parachute canopy is made up of panels.

If you are referring to a string with no fingers on it, it is called an open string.
