There may be times when the text in a reminder template appears a little crowded, depending on the amount of information being included. 

The best way to resolve this is to add a line space to the template after the first group of text. Then, add your additional text (ie. custom confirm/reschedule/cancel instructions, etc) after the line space. Once this is completed, the new text will appear on a new line in the reminders.

If you'd like to use the built in confirm/reschedule instructions (which can be activated in your Reminder Settings), you will still need to add some custom text after the line space in the reminder template to achieve the same desired spacing.
