How long is a Planck length?

I don't need Planck's constant...
I am really interested in the Planck length, the size in which Quantium fluctulations become huge

Answer
The Planck length is the scale at which classical ideas about gravity and space-time cease to be valid, and quantum effects dominate. This is the ‘quantum of length’, the smallest measurement of length with any meaning.
And roughly equal to 1.6 x 10-35 m or about 10-20 times the size of a proton.

The Planck length is 1.61624E-35

planck lenth is a part of planck units . these units are devised from universal constants like h,G,c etc. these have been derived so that if we want to send a maessage to some other planet (if ever we find one with some life and brains ofcourse!!) these units could be helpful as they might not understand metre but will surely understand c=speed of light
at last plank length=10^-35 metres

The value of Planck's constant is about 6.6 X 10 exp -34 Joule-Secs
I don't know what a "planck length" is.

I think the reason you can't find your answer is because you're really looking for Planck's CONSTANT. It's used in an equation to find the energy involved in a photon and its value is 6.626068 x 10^-34 m^2kg/s.

The size of your leg.
