Most of the time you want maximum copper in both power and ground. Bear in mind that the ground copper carries all the return currents from every supply connection, do make more ground than supply current. Preferably, use supply and ground copper areas rather than traces and make sure every active device has adequate supply decoupling according to the manufacturer's advice in their datasheets and apps notes.

Also, see (2.2), (4), 5() and (6) in: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f)

Are you talking about digital or analogue ?   For CMOS digital, the VCC and GND should be fairly equal as half the transistors switch relative to VCC and half to GND.  For analogue it depends whether you have +/- supplies or not.

Good point Mike, A combination of Autocorrupt and haste managed to mess up quite what I was trying to say and I only gave half the story. 4/10. Must try harder.

andyfierman, I'm two weeks into using this EasyEDA. I'm a hobbyist with some electronic knowledge from college years ago. Could you tell me why power and GND traces donot show up in the PCB? I click save before clicking on Convert to PCB. It's extremely frustrating me. Appreciate any help! Thank you, Ed

"Could you tell me why power and GND traces donot show up in the PCB?" Your project is private so only you can see it. Without sight of your project any advice to you is therefore only a guess. My guess is that you have not named your nets using net labels in the schematic.
