Lone pair repulsion: Bond angle is affected by the presence of lone pair of electrons at the central atom. A lone pair of electrons at the central atom always tries to repel the shared pair (bonded pair) of electrons. Due to this, the bonds are displaced slightly inside resulting in a decrease of bond angle.
2- it also depend upon electronegativity , as electronegativity decrease , bond angle decreases . 
3- hybridisation , 
sp 2 – 120 degree , 
sp3 – 109 degree 28 minute 
sp – 180 degree , 
so, as s charecter increases bond angle increases , 
AND THE SIZE DONOT HAVE ANY INFLUENCE ON BOND ANGLE . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
