  We argue that the spin of the 750 GeV resonance can be determined at the
99.7% confidence level in the di-photon channel with as few as 10 fb$^{-1}$ of
luminosity. This result is true if the resonance is produced by gluon fusion
(independently of the selection cuts) while an appropriate choice of selection
cuts is needed if quark production is sub-dominantly present--which is the case
of the Kaluza-Klein gravitational excitation under the hypothesis of a spin-2
resonance. A proportionally larger luminosity is required if the model for the
spin-2 resonance includes a dominant production by quarks or in the absence of
an efficient separation of the signal from the background.
