UserControl size changes after inserting in Form

I have a Windows Form class named UI which has initially no controls in it. There is a custom UserControl StartPage which has size 422, 117.

When I add StartPage in UI its size changes

UserControl c = new StartPage();
c.Dock = DockStyle.Top;          // Also tried DockStyle.Fill
// Size here: 422, 117

Controls.Add(c);
// Size here: 406, 117

What is happening and how do I prevent this behavior? I basically want the UI to automatically resize itself to contain StartPage without using AutoSize property.

Is there any standard way to achieve this behavior?

Another solution is to change the AutoScaleMode to Inherit in the usercontrol. This takes care of the scaling issues. By default, it will have the value "Font".

AutoScaleMode = Inherit

It happens because of the font, change the usercontrol font to the parent form font and everything will be load as expected.

You should increase your form width, currenctly it is to small - so usercontrol is being resized. You can do it in runtime like this:

UserControl c = new StartPage();
c.Dock = DockStyle.Top; 

Width = c.Width + Width - ClientSize.Width;
Height = c.Height + Height - ClientSize.Height;

Controls.Add(c);
