draw an icon with a circle

[stranger123]

Hi,

Please point me where I should go for help if I am in a wrong place for this question!
I tried to draw an icon with a circle and found the "circle" was not so smooth. I just cannot understand how the people can make such smooth circle in the same size icon as mine.
Any idea?

It is probably your resolution. I am guessing this is for web work, and you are starting out with the icon actual size at 72dpi. If you start with the icon larger then final size, and resize it once it is finished, this may help. The other choice is to keep the icon the same size, but increase the resolution to 96 dpi to see if that helps, if not try 150 or 300 dpi.

Other options are available, but hopefully this will get you pointed in the right direction.
