C# - Padding TabPage справа

Question

Мой TabPage накладывается на элементы управления TabControl потому что его ширина слишком велика. Мне нужно либо уменьшить его ширину, либо добавить его вправо.

(Как видно на этой картинке, фактическое TabPage накладывает кнопки слева).

Вот мой обычай TabControl учебный класс.

        {
            base.CreateHandle();
            Alignment = TabAlignment.Left;
        }

        protected override void OnHandleCreated(EventArgs e)

            base.OnHandleCreated(e);

            FlatColors colors = Helpers.GetColors(this);

            _ActiveColor = colors.Flat;
        }
    }
}

Как мне этого добиться?

Благодаря предложению @HansPassant я воссоздал TabControl без вкладок, изменил ItemSize и только потом перепутал с внутренним кодом.
