XStart and YStart serve the purpose of re-creating a particle from a
mask after "Analyze Particles", since the point (XStart, YStart) is
guaranteed to be *inside* the particle.

What you want is most likely the dimensions of the bounding rectangle
that you get by activating 'Bounding rectangle' in the 'Analyze > Set
Measurements...' dialog. It will record BX and BY, the coordinates of
the upper left corner of the rectangle, with BX being the value you want.

See the documentation:

Cheers,
Jan
