Depending on the design of the instrument, some instruments have a

length of the instrument but can only play the odd harmonics
thereof (1/4, 3/4, 5/4 ...).
This is for pipes. Strings should have the length of the wave length
in the string (not the sir, though). ...
This is wrong for strings: they get the same series as for open pipes.
They get a standing wave with minimum amplitude at both ends, and can
have a maximum in the middle, so the whole thing is one half wave
length.
