Menu Problem
hi , i have a problem how can i fix size of menu because when i click maximise on play the size changed like that 
how can i make it changed with the scene size?????
There is a manual section covering this : Designing UI for $$anonymous$$ultiple Resolutions. You need to understand how anchors and pivots work, it's really not that hard.
The Players won't have a Free aspect windows so you should do as @corn said and also have a pre determined windows sizes but an easy solution would be setting from Canvas > Canvas Scaler component UI Scale Mode to Scale with screen size and set a reference resolution.
