My tape measure isn't long enough and my string keeps getting tangled.

Then pull off another 10% as a safety margin and cut the string. There is no point in attempting to use this piece though because it is too short. So cut another piece that is 1.5 times as long as the first. This one will be way too long so you will need to try to use it, and trim to fit. This may take several tries, but don't get discouraged. Once you finally get it trimmed to the perfect length, remove it from the project and measure it carefully with a tape measure. That will be close to the length of string that you will need. Write down that number, and wrap another piece of string around your finger so that you don't forget it.
Do you, by any chance, work for a government regulation writing agency?

If this is for real....

Nail 2 nails on a flat surface a set distance apart (1 foot, 1 meter etc). Make some appropriate markings between the nails (inches, centimeters etc).

Mark off 6" of string for the end you will tie to one nail and tie it on starting at that mark (whatever hangs off is already counted) Wind the string around the nails counting the number of complete wraps. Each wrap equals twice your set distance (2 feet, 2 meters etc + your tie amount).

When you get to the end measure it against the markings you made between the nails previously (i.e halfway would be 6" or 50cm etc).

Add it all up for a total that is going to be within 1% of your actual total (loose a tiny amount of distance going around the nails).

Tie amount + (wraps X2) + end remnants = string length

If you need more precision than this....why are you using string?

I'm gonna lose distance going around the nails? Wouldn't that be making my string longer?

I never knew string was so complex.

Yes your string will be longer - you lose a bit in the measurement - not the string. One could inset the nails a tenth or so to compensate....

But isn't a longer string better?

Twice the distance from an end to the middle.

I gave up on string years ago. I now use rope with much greater satisfaction.

Is this the well known string theory? Or knot?
