You can create JPanel and override it's getPreferredSize method and return some desired dimension. Then add that JPanel to your JOptionPane.

Rough example:

JPanel panel = new JPanel() {
            @Override
            public Dimension getPreferredSize() {
                return new Dimension(320, 240);
            }
        };

//We can use JTextArea or JLabel to display messages
JTextArea textArea = new JTextArea();
textArea.setEditable(false);
panel.setLayout(new BorderLayout());
panel.add(new JScrollPane(textArea));

JOptionPane.showConfirmDialog(null,
            panel, //Here goes content
            "Here goes the title",
            JOptionPane.OK_CANCEL_OPTION, // Options for JOptionPane
            JOptionPane.ERROR_MESSAGE); // Message type
