Extend colums to twice visiable?

I have in my TCSTART.BTM "window max" but I would like the columns to be twice that which is visable. How can I do this please?

And I mean the above question for TCC, not TCMD......

TCC 16.02.48 x64 Windows 7 [Version 6.1.7601]
TCC Build 48 Windows 7 Build 7601 Service Pack 1
In the console's properties dialog (Alt-Space, p), under "Layout", give the "Screen Buffer Size" a greater width. The width of the window is limited by the width of the console screen buffer.
I tried TCMD and didn't see Properties, same with TCC, now I do if I just do CMD..... Is that correct?
The console's properties have been in the same place for 20-some years. Start TCC (not TCMD) and click the icon in the upper-left corner of the console window and choose "Properties".
