  The purpose of this work is to provide theoretically grounded assessment on
both the field-of-view and the bandwidth of a lensless holographic setup.
Indeed, while previous works have presented results with super-resolution and
field-of-view extrapolation, there is no well established rules to determine
them. We show that the theoretical field of view can be hugely large with a
spatial-frequency bandwidth only limited by the wavelength leading to an
unthinkable number of degrees of freedom. To keep a realistic field of view and
bandwidth, we propose several practical bounds based on few setup properties:
namely the noise level and the spatio-temporal coherence of the source.
