Azulykit said:There is a common "rule" for 3 dB beamwidth. It starts breaking down for low gain antennas (6-8 dBi) so use it with caution.
BWdeg=65/(D/λ)
where D is the dimension in the plane where you are estimating beamwidth and λ is, of course, wavelength in the same units.

I read from one book
Horizontal Beamwidth = 115λ/L
Vertical Beamwidth=50λ/L
These are approximate formulas.
