GUI wont distribute evenly

W$$anonymous$$le both of the above answers will solve your problem, they're not what you want. For a bunch of buttons laid out in a grid, the selection grid will work, but suppose you wanted to have the fourth box (of the same size) to be a different GUI element, the selection grid would not work.

Similarly, hardcoding the button button sizes and positions works fine, but opens up a whole different can of worms. If your GUI is designed in photoshop beforehand or you have a fixed display size and resolution, then a hard positioned GUI isn't terrible to build. On the other hand, if you want to be flexible, it takes a lot more work with setting the sizes and positions.

With all that said, here's how to do it with GUILayout:

 **Vector2 boxSize = GUI.skin.button.CalcSize(new GUIContent(p3String));**
         
         GUILayout.BeginArea(new Rect(Screen.width / 4, Screen.height /4, Screen.width/2, Screen.height/2));
         GUILayout.BeginVertical();
             GUILayout.BeginHorizontal();
                 **if (GUILayout.Button(p1String,GUILayout.MinWidth(boxSize.x)))**
                 {
                     PlayerPrefs.SetString("currentProfile", "1");
                     Application.LoadLevel("gameStage");
                 }
                 
                 **if (GUILayout.Button(p2String, GUILayout.ExpandHeight(true)))**
                 {
                     PlayerPrefs.SetString("currentProfile", "2");
                     Application.LoadLevel("gameStage");
                 }
                 
            GUILayout.EndHorizontal();
         GUILayout.EndVertical();
 
         GUILayout.BeginVertical();
         GUILayout.BeginHorizontal();
             if (GUILayout.Button(p3String))
             {
                 PlayerPrefs.SetString("currentProfile", "3");
                 Application.LoadLevel("gameStage");
             }
             if (GUILayout.Button(p4String))
             {
                 PlayerPrefs.SetString("currentProfile", "4");
                 Application.LoadLevel("gameStage");
             }
             GUILayout.EndHorizontal();
         GUILayout.EndVertical();
         GUILayout.FlexibleSpace();
         GUILayout.EndArea();

I starred the relevant lines. Basically you can use GUIStyle.CalcSize to get the amount of space that would be taken up by the guiContent of that style. (In t$$anonymous$$s case, since you are drawing buttons, I used the GUIStyle for the default button). Then you can use a GUILayout option to set the minimum width of the first box to the width of the bigger buttons. I also made the second profile box expand height to match.

To make t$$anonymous$$s more generic, you could loop over every button and find the max width and height, and set each button to use that width and height.

You could use a SelectionGrid. It would handle the layouting itself. You could also override the precalculated button width and height by using GUILayoutOptions.

EDIT: You see a working example of SelectionGrid in the GUI Scripting Guide under Controls.

I'm not sure w$$anonymous$$ch comment you are refering to mine or Jamora's :D If it's Jamora's then you'll have to do some research yourself as I have no idea about selection grid yet.

As for mine.I took a look at your code and in it everyt$$anonymous$$ng is fine until you pass information into the buttons.They simply deform.But if the second button contains information then everyt$$anonymous$$ng seems to even out.Not sure why though.

Also what I did with your code was simply change

 if(GUILayout.Button(p1String))
 {
   //What is inside here is unaltered.
 }

to

 if(GUI.Button(new Rect(100,100,100,100),p1String))
 {
   //your logic
 }

Still does the same t$$anonymous$$ng but you can control the size and position of the button.

I strongly suggest you take a look at Jamora's links as they are helpful :)
