How do I increase the size of a CheckBox in Winforms?

There's an AutoSize option in the Properties windows; if you turn that off by changing it to False , you will be able to modify the size of your CheckBox .

You can determine titlebar height for both tool-windows and normal forms by using:

Rectangle screenRectangle = this.RectangleToScreen(this.ClientRectangle);  int titleHeight = screenRectangle.Top - this.Top;

Where 'this' is your form.

ClientRectangle returns the bounds of the client area of your form. RectangleToScreen converts this to screen coordinates which is the same coordinate system as the Form screen location.
