Particles always in random size I am making a sprinkles on donut using particles but blender (2.79a) changes the size of the particles even though, random size is on 0 value.



Edit:

I tried changing type to emitter which made the them all same size but, also resulted in sprinkles placed randomly around glazing



I also have a box under my glazing which is only place I can use to move the glazing and I wonder if this is a cause of my problem.
Thanks for you answers guys! 

As Mr Zak pointed Random in my Velocity settings was set to 1 instead of 0 which I probably changed to see what it is doing and simply turn it to 1 thinking that is the default value. I changed it back to 0 and all the particles are the same size. 

Again, thanks for your help!
