Quick Reference: Formatting at a Glance

Before we dive into the details, here's what you need to know for each major style:

APA 7th Edition:

• Margins: 1 inch on all sides
• Font: 12-point Times New Roman, 11-point Arial, or 11-point Calibri
• Spacing: Double-spaced throughout
• Paragraph indent: 0.5 inches

MLA 9th Edition:

• Margins: 1 inch on all sides
• Font: 12-point Times New Roman (preferred) or similar readable font
• Spacing: Double-spaced throughout
• Paragraph indent: 0.5 inches

Chicago 17th Edition:

• Margins: 1 inch on all sides (some require 1.25 inches on left)
• Font: 12-point Times New Roman or similar serif font
• Spacing: Double-spaced for papers, single for theses (check requirements)
• Paragraph indent: 0.5 inches

APA Format Requirements

The American Psychological Association (APA) style is the standard for social sciences, psychology, education, and nursing papers.

Margins in APA

Set 1-inch margins on all four sides of your document:

• Top: 1 inch
• Bottom: 1 inch
• Left: 1 inch
• Right: 1 inch

This applies to every page, including the title page, abstract, and references.

Font Requirements for APA

APA 7th edition accepts several fonts. Choose one and use it consistently:

Acceptable fonts:

• Times New Roman, 12 point
• Arial, 11 point
• Calibri, 11 point
• Georgia, 11 point

Important: Your entire paper should use the same font. Don't mix Arial headings with Times New Roman body text.

Line Spacing in APA

Double-space everything, including:

• Body text
• Block quotes
• Reference list entries
• Title page
• Abstract

There's no extra space between paragraphs beyond the standard double spacing.

Paragraph Indentation

Indent the first line of every paragraph 0.5 inches (half an inch). This is the default tab setting in most word processors.

Exception: Don't indent the abstract, block quotes, headings, or reference list entries (reference entries use a hanging indent instead).

Page Numbers

• Position: Top right corner
• Start numbering from page 1 (title page)
• Include running head on the same line (for professional papers)

Running Head (Professional Papers Only)

If required, the running head appears in ALL CAPS at the top left of each page. Maximum 50 characters including spaces.

Example: EFFECTS OF SOCIAL MEDIA ON STUDENT PERFORMANCE

MLA Format Requirements

The Modern Language Association (MLA) style is standard for humanities, literature, and language papers.

Margins in MLA

Like APA, MLA requires 1-inch margins on all sides:

• Top: 1 inch
• Bottom: 1 inch
• Left: 1 inch
• Right: 1 inch

Font Requirements for MLA

MLA recommends an easily readable font in 12-point size:

• Times New Roman (most common choice)
• Arial
• Courier New
• Calibri

When in doubt, use Times New Roman 12pt. It's universally accepted.

Line Spacing in MLA

Double-space the entire document, including:

• Body paragraphs
• Block quotes (indented 0.5 inches from left margin)
• Works Cited page
• Header information

Don't add extra spacing between paragraphs or after headings.

MLA Header Format

MLA doesn't use a title page unless specifically requested. Instead, include this header on the first page:

Your Name
Professor's Name
Course Name
Date (Day Month Year format: 13 May 2026)

                    Your Centered Title

Each line is double-spaced. The title is centered but not bolded, underlined, or in a larger font.

Page Numbers

• Position: Top right corner
• Format: Your last name followed by the page number
• Example: Smith 3
• Appears on every page, starting from page 1

Paragraph Indentation

Indent the first line of each paragraph 0.5 inches. Use the Tab key once (don't use multiple spaces).

Chicago Style Requirements

The Chicago Manual of Style is used in history, fine arts, and some humanities disciplines. There are two systems: Notes-Bibliography and Author-Date.

Margins in Chicago

Standard margin requirements:

• Top, Bottom, Right: 1 inch
• Left: 1 inch (or 1.25 inches if binding is required)

Some institutions require larger left margins for bound submissions.

Font Requirements for Chicago

Chicago recommends:

• Times New Roman, 12 point
• Any readable serif font in 10-12 point size

Consistency is key. Choose one font and stick with it.

Line Spacing in Chicago

Paper type matters:

• Student papers: Double-spaced throughout
• Theses/dissertations: May be single-spaced (check with your institution)
• Footnotes: Single-spaced within, double-spaced between
• Bibliography: Single-spaced within entries, double-spaced between

Title Page in Chicago

Unlike MLA, Chicago papers typically include a title page:

• Title centered, about 1/3 down the page
• Your name centered below the title
• Course information, instructor name, and date centered at the bottom
• No page number on the title page

Page Numbers

• Position: Either top right or bottom center
• Start numbering from the first page of text (not title page)
• Use Arabic numerals (1, 2, 3...)

Common Formatting Mistakes to Avoid

These errors cost students points on nearly every paper:

1. Inconsistent Spacing

Wrong: Adding extra space after paragraphs or before headings Right: Uniform double-spacing throughout

In Microsoft Word, check Paragraph settings and ensure "Before" and "After" spacing is set to 0.

2. Wrong Indentation Method

Wrong: Using the space bar five times to indent Right: Using Tab or setting a 0.5-inch first-line indent

Spaces create inconsistent indents across your document.

3. Multiple Fonts

Wrong: Using Times New Roman for body text and Arial for headings Right: Using the same font family throughout (unless specified otherwise)

4. Incorrect Margins

Wrong: Default Word margins (1.25" left and right) or 0.75" margins Right: Setting all margins to exactly 1 inch

5. Page Number Errors

Wrong: No page numbers, or page numbers in wrong position Right: Consistent page numbering as specified by your citation style

6. Not Using Hanging Indents

Wrong: Indenting the first line of reference/Works Cited entries Right: Using a hanging indent (first line flush left, subsequent lines indented 0.5")

FAQ

What font should I use if my professor doesn't specify?

Times New Roman, 12 point is the safest choice. It's accepted by APA, MLA, and Chicago styles and is universally recognized as a professional academic font.

Do I double-space my Works Cited or References page?

Yes. All three major citation styles (APA, MLA, Chicago) require double-spacing on the reference page. Use hanging indents for each entry.

Should I justify my text (even margins on both sides)?

No. Academic papers should use left-aligned (ragged right) text alignment. Justified text can create awkward spacing between words.

Do headers and footers count toward the 1-inch margin?

No. Page numbers and running heads appear within the 1-inch margin area, typically 0.5 inches from the edge of the page.

How do I format block quotes?

For quotes over 40 words (APA) or 4 lines (MLA/Chicago):

• Start on a new line
• Indent the entire quote 0.5 inches from the left margin
• Don't use quotation marks
• Place citation after the final punctuation

Can I use a sans-serif font like Arial?

For APA: Yes, 11-point Arial is explicitly allowed. For MLA: Yes, if it's easily readable. For Chicago: Generally no — serif fonts (like Times New Roman) are preferred.
