Window length and spectral resolution

[Eli J]

If I’m understanding correctly, the spectral resolution for Fourier analysis is given by 1/[window size]. However, when I use Praat’s default settings (0.005s window size, which would give a 200 Hz spectral resolution using this formula) and take a spectral slice at a point in time, it looks like the frequencies are about 86 Hz apart. What have I misunderstood here?
