Legal Fonts: Why It Matters What You Use

Legal fonts matter because they directly influence how your documents are perceived—and whether they meet official formatting standards.

In legal writing, even subtle design elements like font size and style can affect clarity, authority, and professionalism.

Typography reflects the discipline and precision expected in the legal profession. That’s why most legal documents follow strict formatting conventions around font, spacing, margins, and layout.

Why Legal Fonts Matter

Bottom line: your font isn’t just part of the design—it’s part of the argument. Make it count.

Factors to Consider When Choosing Legal Fonts

The best legal font for your firm depends on more than just aesthetics. To ensure your documents are professional, compliant, and easy to read, here are the most important factors to keep in mind.

1. Document Type and Purpose

Start by matching your font to the purpose and tone of your document. Formal legal materials—like contracts, legal briefs, and court filings—require fonts that convey professionalism and adhere to formatting expectations. Informal materials, such as newsletters or brochures, allow for more flexibility.

For official filings, it’s safest to choose a standard legal document font like Times New Roman, Garamond, or Century Schoolbook. These fonts signal professionalism and are commonly accepted by courts.

If you’re not sure what’s appropriate for the situation, this overview of legal font choices can help guide the decision.

2. Audience and Jurisdiction

Consider who will read your document: judges, attorneys, clients, or the general public. A clear, consistent font helps communicate your message effectively across all audiences.

Equally important are jurisdictional font rules. Courts across the U.S. have varying formatting requirements. For example:

• The U.S. Supreme Court recommends Century family fonts like Century Schoolbook, praised for their legibility and formal appearance. Here’s why many legal professionals prefer it.

• The Seventh Circuit Court of Appeals has gone as far as to discourage the use of Times New Roman, emphasizing more readable alternatives in their official practitioner’s handbook.

• Some state courts publish lists of approved fonts or specify exact requirements for font size and style.

Before finalizing your document, be sure to check the local rules or your state bar association’s guidance to avoid formatting issues.

3. Serif vs. Sans Serif Fonts

Fonts fall into two main categories: serif and sans serif.

• Serif fonts have small decorative lines at the ends of characters. They convey a more traditional, authoritative tone—ideal for printed legal documents and formal court filings.

• Sans serif fonts are simpler and cleaner, often used in digital formats and modern branding. They’re easier to read on screens and well-suited for informal or internal use.

Choosing between them depends on your audience, the format (print vs. digital), and your law firm’s brand personality.

Curious why Times New Roman became the legal industry default? This history explains its widespread adoption.

4. Compatibility and Accessibility

Your font should render consistently across devices, operating systems, and document creation software like Microsoft Word or Google Docs. This is especially important when your work will be viewed digitally—on mobile devices, PDFs, or websites.

Avoid obscure or novelty fonts that may not display correctly for the recipient. Look for web-safe, accessible fonts that maintain legibility and formatting across platforms.

Also consider visual accessibility. Select fonts that support screen readers, offer strong contrast, and avoid overly narrow or stylized characters. The more readable your documents are, the more professional and inclusive your communication becomes.

Top Recommended Fonts for Legal Documents

Some fonts have stood the test of time in the legal field—for good reason. Whether you’re preparing formal legal documents, internal memos, or client-facing materials, the right font ensures professionalism, readability, and compliance with formatting rules.

Below are the most commonly used and trusted legal fonts, along with insights on when (and when not) to use them.

Times New Roman

Still one of the most recognized fonts for legal documents, Times New Roman is the go-to serif font for many courts, law schools, and firms. It’s known for its readability, formality, and compatibility with nearly all word processors.

However, it’s worth noting that some courts, such as the Seventh Circuit, have recommended against it due to its dense appearance in digital formats. Learn more about its legal history here.

Best used for: Court filings, contracts, and formal printed documents
Watch out for: Overuse or when a more modern impression is needed

Century Schoolbook

This serif font is widely recommended by courts, including the U.S. Supreme Court, for its classic feel and exceptional readability. Its generous spacing makes it ideal for legal briefs and printed legal work.

Explore why lawyers are switching to Century Schoolbook.

Best used for: Court briefs, appellate filings, and formal litigation
Watch out for: Slightly larger character width may add length to your documents

Garamond

Elegant, timeless, and well-suited to formal legal documents. Garamond is less dense than Times New Roman, offering a more refined tone without sacrificing readability.

Best used for: Estate planning documents, firm brochures, or contracts requiring a sophisticated appearance
Watch out for: Can appear too delicate in small font sizes or on low-resolution screens

Arial

A sans serif font favored in digital-first settings, Arial is clear, neutral, and widely accepted. It’s especially useful in PDFs and digital documents where screen readability is a concern.

Best used for: Internal memos, digital filings, or court documents where allowed
Watch out for: Can feel too informal for high-stakes, formal submissions

Calibri

As the default font in many versions of Microsoft Word, Calibri has become increasingly common in legal workflows. It’s approachable and easy to read on screen, making it a good choice for digital formats and client-facing materials.

Best used for: Emails, client letters, digital documents, or casual correspondences
Watch out for: Readability at smaller sizes and lack of formality in high-level filings

Book Antiqua

This serif font combines formality with a softer tone, making it a smart alternative to Times New Roman or Garamond. It’s rarely court-mandated, but it’s a tasteful option when flexibility allows.

Best used for: Contracts, formal communications, and brand-forward documents
Watch out for: May appear too stylized if paired with modern layout designs

Courier New

A monospaced, typewriter-style font that remains in use for certain legal documents where line alignment and spacing uniformity are key—such as transcripts or code-based exhibits.

Best used for: Transcripts, deposition summaries, or documents requiring strict layout consistency
Watch out for: Outdated appearance in general-use legal documents

Expert Insight on Typography

In Typography for Lawyers, Matthew Butterick reminds us:

“Typography matters because it helps conserve the most valuable resource you have as a writer—reader attention.”

That attention is limited. Poor font choices distract. Good typography? It guides the reader effortlessly through your message.

Best Practices for Using Legal Fonts

Choosing the right legal font is just the beginning. How you use it—across style, size, spacing, and consistency—affects how your documents are read, perceived, and received. Below are key practices that ensure your documents stay readable, professional, and compliant.

1. Choose a Font Size That Prioritizes Readability

Most legal documents should use a font size between 10 and 14 points. Courts typically recommend 12-point font as a standard, but appellate briefs and accessibility-focused content often require 14-point.

If your jurisdiction has strict formatting rules, ignoring them can lead to delays—or outright rejections. Always review the legal document font size requirements in your court’s style guide before submission.

2. Use Font Styles That Match the Document’s Purpose and Medium

When in doubt, match your font to the tone and delivery format of your document:

• For court filings and printed legal documents: Choose serif fonts like Times New Roman, Garamond, or Century Schoolbook.

• For internal memos, digital documents, and websites: Use clean sans serif fonts such as Arial, Calibri, or Open Sans.

Avoid illegible fonts, novelty designs like Comic Sans, or overly stylized typefaces. These reflect poorly on your professionalism—and may violate court-approved font lists.

3. Keep Fonts Consistent Throughout the Document

One of the most common formatting mistakes? Mixing multiple fonts in a single document.

Stick with a single font for body text. If needed, you can introduce one complementary font for section headers or pull quotes—but even then, it should feel cohesive.

A good rule: If it looks like more than two fonts, it’s too many.

Consistency reinforces your firm’s branding, improves scannability, and presents a more polished document.

4. Format Spacing and Layout for Readability

Font choice isn’t the only factor that influences legibility—spacing matters, too.

Use:

• 1.5 or double line spacing for court filings and lengthy documents

• Standard margins (usually 1 inch on all sides)

• Uniform paragraph spacing to prevent visual clutter

Tight line spacing or inconsistent margins not only reduce readability but may violate specific rules for legal briefs or contracts.

5. Use Emphasis Sparingly and Strategically

Visual emphasis can guide your reader—but too much, and it becomes a distraction.

Use bold for section titles or labels, italics for references or citations, and avoid underlining unless a court requires it. Never bold entire paragraphs or use multiple emphasis types at once.

Think of emphasis as a highlighter for your reader’s brain—one swipe is enough.

6. Ensure Digital Compatibility and Accessibility

In today’s hybrid environment, your documents will likely be shared across multiple platforms—from email and document software to mobile devices.

To ensure compatibility:

• Choose fonts that render well in Word, Google Docs, PDFs, and modern web browsers

• Preview documents on desktop and mobile devices

• Follow accessibility standards—select fonts with clear shapes, strong contrast, and screen reader support

This helps your documents reach more people—and reflects a higher standard of professionalism.

7. Follow Jurisdiction-Specific Font Rules

Lastly, and most importantly: follow the rules.

Many courts publish strict formatting guidelines that include:

• Required typeface (e.g., Century Schoolbook)

• Approved font sizes and styles

• Restrictions on line spacing and margins

Using a non-compliant legal document font style could result in a rejected filing. When in doubt, check your jurisdiction’s handbook or court website for font-specific requirements.

Fonts to Use for Your Law Firm Website

So far, we’ve focused on choosing the right legal font for documents—contracts, court filings, and formal communications. But your font decisions shouldn’t stop there.

The same principles of readability, consistency, and professionalism also apply to your law firm’s website—where clients often get their very first impression of your firm.

Why web font choice matters

The font on your website influences how your firm is perceived before anyone reads a single word of your bio or practice area page. It impacts:

• User trust and confidence in your brand

• How long visitors stay on your site

• Whether your content feels credible and accessible

In short, your website font is part of your branding—and a critical one at that.

What to Look for in a Website Font

1. Use Web-Safe, Readable Typefaces

Stick with fonts that render cleanly across browsers, devices, and screen sizes. These fonts are designed for the web, load quickly, and improve user experience.

Some proven choices:

• Open Sans – neutral and modern

• Roboto – professional, great on mobile

• Lato – humanist sans serif, warm but clean

• Source Serif Pro – great serif option for digital use

Avoid fonts that are overly ornate, slow to load, or hard to read on mobile. Accessibility and clarity should always come first.

2. Match the Font to Your Brand Personality

A bold, minimalist font might suit a business litigation firm. A softer sans serif might resonate more for immigration or family law practices. The right font helps communicate your firm’s tone—before anyone even picks up the phone.

Tip: If you’re unsure what fonts reflect your practice’s tone, look at brands outside the legal space that align with your values and take notes.

3. Limit Your Font Pairing to Two (Max)

Use one font for headlines and another for body text, if needed—but keep it simple. A strong primary font is usually enough to establish your identity. Add a secondary font only if it enhances readability or structure.

4. Prioritize Accessibility and Compatibility

Use fonts that:

• Are legible at smaller sizes

• Work across all modern browsers

• Offer enough contrast for visual accessibility

• Look just as good on mobile devices as they do on desktop

Well-chosen web fonts improve UX—and that means more people staying on your site longer.

The bottom line? Your website font should support your brand, not distract from it. When chosen carefully, it can subtly communicate trust, clarity, and confidence—exactly what prospective clients are looking for.
