  We have measured the quasiparticle generation-recombination (GR) noise in
aluminium lumped element kinetic inductors with a wide range of detector
volumes at various temperatures. The basic detector consists of meandering
inductor and interdigitated capacitor fingers. The inductor volume is varied
from 2 to 153 {\mu}m^{3} by changing the inductor width and length to maintain
a constant inductance. We started with measuring the power spectrum density
(PSD) of the detectors frequency noise which is a function of GR noise and we
clearly observed the spectrum roll off at 10 kHz which corresponds to the
quasiparticle lifetime. Using data from a temperature sweep of the resonator
frequency we convert the frequency fluctuation to quasiparticle fluctuation and
observe its strong dependence on detector volume: detectors with smaller volume
display less quasiparticle noise amplitude. Meanwhile we observe a saturated
quasiparticle density at low temperature from all detectors as the
quasiparticle life time {\tau}qp approaches a constant value at low
temperature.
