Understanding PowerPoint Footnote Options

Before we dive into the specific methods, it’s important to understand the different types of footnotes you can create:

  • Reference Citations (for sources and quotes)
  • Explanatory Notes (for additional context)
  • Legal Notices (for disclaimers and copyrights)
  • Image Credits (for visual content attribution)

Method 1: Using Text Boxes and Separator Lines

This method gives you the most flexibility and control over your footnotes’ appearance.

1. Create the Footnote Area

Add a Separator Line

  1. Navigate to the Insert tab
  2. Click on Shapes
  3. Select the Line tool from the Lines section
  4. On your slide:
    • Position your cursor about 1 inch from the bottom
    • Click and drag to draw a horizontal line
    • Hold Shift while drawing to ensure it’s perfectly horizontal
  5. Format the line:
    • Right-click the line and select “Format Shape”
    • Set the line color to a subtle gray (suggest: RGB 180, 180, 180)
    • Adjust the width to 1pt or 1.5pt
    • Set the line transparency to about 40%

Create the Text Box

  1. Go to Insert > Text Box
  2. Draw the text box below your separator line:
    • Leave about 0.1 inches of space below the line
    • Extend the box almost to the slide edges
    • Allow for about 0.5 inches of margin on each side
  3. Format the text box:
    • Set font size to 8-10 points
    • Choose a slightly lighter color than your main text
    • Consider using Arial or Calibri for clarity
    • Set line spacing to “Exactly 10pt”

2. Add Footnote Numbers or Symbols

In Your Main Content

  1. Place your cursor where you want the footnote reference
  2. Type your reference number or symbol
  3. Format it as superscript:
    • Select the number/symbol
    • Press Ctrl+Shift+Plus (or Ctrl+D for font dialog)
    • Check the “Superscript” option
    • Reduce the superscript size by 2 points from your main text

In the Footnote Area

  1. Type the corresponding number or symbol
  2. Add space after the number
  3. Type your footnote text
  4. Consider formatting options:
    • Italic for source titles
    • Regular text for explanations
    • Include URLs when relevant
    • Add publication dates in parentheses

3. Create a Slide Master Template

This step ensures consistency across your presentation:

  1. Go to View > Slide Master
  2. Select the main master slide
  3. Add your footnote elements:
    • Insert the separator line
    • Create the text box placeholder
    • Set all formatting
  4. Configure positioning:
    • Use guides for precise placement
    • Check alignment with other elements
    • Verify spacing is consistent
  5. Save the master:
    • Close Slide Master view
    • Apply changes to all slides
    • Test with different content amounts

Method 2: Using a custom footer

This method works well for consistent footnotes that appear on multiple slides.

1. Configure the Footer

  1. Go to Insert and then select the Header & Footer tab in the Ribbon.
  2. In the dialog box:
    • Check the “Footer” checkbox, then Click the “Custom” option if available
    • Type your initial footnote text
    • Consider date and slide number options
  3. Apply the footer:
    • Click “Apply to All” for consistency, then Use “Apply” for single-slide footnotes
    • Preview the result before confirming

2. Customize the Footer Area

Adjust Placement

  1. Select the footer placeholder:
    • Click on the border, then Look for the dotted edge
    • Check for selection handles
  2. Modify the position:
    • Drag to reposition
    • Use arrow keys for fine adjustment
    • Align with other elements
  3. Format the space:
    • Adjust margins if needed
    • Verify reading distance visibility
    • Check contrast with background

Method 3: Using Shapes with Links

This interactive method works well for detailed references.

1. Create Reference Numbers

  1. Insert a circle shape:
    • Insert > Shapes > Circle
    • Draw a small circle (about 0.2 inches)
    • Position near referenced content
  2. Add the number:
    • Insert a text box inside the circle
    • Type the reference number
    • Center perfectly
  3. Format the indicator:
    • Group the shapes
    • Add a subtle shadow
    • Consider using brand colors

2. Add Pop-up Notes

For advanced users, this Visual Basic for Applications – VBA code creates interactive footnotes:

vbaCopySub CreateFootnotePopup()
    Dim oSh As Shape
    Dim oTxt As Shape
    Dim oNote As Shape
    
    ' Create numbered circle
    Set oSh = ActiveWindow.Selection.SlideRange(1).Shapes.AddShape( _
        Type:=msoShapeOval, Left:=50, Top:=50, _
        Width:=15, Height:=15)
    
    ' Add number
    Set oTxt = ActiveWindow.Selection.SlideRange(1).Shapes.AddTextbox( _
        Orientation:=msoTextOrientationHorizontal, _
        Left:=oSh.Left + 3, Top:=oSh.Top + 1, _
        Width:=10, Height:=15)
    
    ' Format number
    With oTxt.TextFrame.TextRange
        .Text = "1"
        .Font.Size = 8
        .Font.Color.RGB = RGB(255, 255, 255)
    End With
    
    ' Format circle
    With oSh
        .Fill.ForeColor.RGB = RGB(0, 0, 0)
        .Line.Visible = False
    End With
    
    ' Add hover note
    Set oNote = ActiveWindow.Selection.SlideRange(1).Shapes.AddTextbox( _
        Orientation:=msoTextOrientationHorizontal, _
        Left:=oSh.Left + 20, Top:=oSh.Top - 20, _
        Width:=200, Height:=40)
    
    With oNote.TextFrame.TextRange
        .Text = "Your footnote text here"
        .Font.Size = 10
        .Font.Color.RGB = RGB(80, 80, 80)
    End With
    
    ' Group shapes
    ActiveWindow.Selection.SlideRange(1).Shapes.Range( _
        Array(oSh.Name, oTxt.Name, oNote.Name)).Group
End Sub

Handling Special Cases

Long Footnotes

When dealing with extensive footnotes proceed as following:

  1. Break into multiple lines:
    • Use logical break points
    • Maintain sentence structure
    • Consider bullet points
    • Keep line length consistent
  2. Format for readability:
    • Slightly increase line spacing
    • Use clear paragraph breaks
    • Consider indentation
    • Maintain margin alignment

Multiple Citations

For slides with multiple references:

  1. Organization options:
    • Number sequentially
    • Group by topic
    • Use different symbols
    • Consider columns
  2. Formatting approach:
    • Consistent separators
    • Clear visual hierarchy
    • Logical grouping
    • Space management
