Hi,
I would like to know if it’s possible to fill a surface with particles objects homogeneously ?
The best I have is this.
Thank you for your help 
Hi, i’ve tried and this is my best.
I’ve used a particle system as you, but i’ve applied a texture to influnce the size, in this case a blend texture with sferical blend, mapping generated and influence to size which you will tweak to mach the size you want (you have to tweak also size in particle system and newtonian have to be active).
Hope i helped you

Hi, you can use the Grid option.
