A contract should be set in a readable serif font at 12-point size. Century Schoolbook, Garamond, and Palatino are the strongest choices, and they are the same families that courts specifying typography requirements tend to favor. The right font will not just make the agreement look professional; for certain disclosures and disclaimers, size and prominence are what make the clause legally effective.
The Best Fonts for Contract Body Text
Serif fonts have small finishing strokes at the tips of their letters that help the eye track across long lines of text. For printed contracts and PDFs, they remain the standard. The U.S. Supreme Court requires booklet-format filings to use a Century family font (Century Expanded, New Century Schoolbook, or Century Schoolbook) in 12-point type.1Legal Information Institute (LII) at Cornell Law School. Supreme Court Rules Rule 33 – Document Preparation: Booklet Format; 8 1/2- by 11-Inch Paper Format The Seventh Circuit’s typography guide recommends Century, Baskerville, Caslon, and Palatino, calling them typefaces designed for books that maximize legibility in legal writing.2United States Court of Appeals for the Seventh Circuit. Practitioner’s Handbook for Appeals
Any of the following will produce a professional, readable contract:
- Century Schoolbook. Wide letterforms, generous spacing, and excellent readability at 12 points. The safest universal pick.
- Garamond. Elegant and highly readable, with standard-width characters that avoid the cramped look of narrower fonts. Works well for long agreements.
- Palatino. Designed for body text in books, with slightly larger proportions that stay forgiving at smaller sizes.
- Baskerville. A clean, high-contrast serif that reads well in both print and PDF. Studies have found readers rate statements set in Baskerville as more credible than the same text in other fonts.
- Book Antiqua. Similar to Palatino but with a softer appearance. A solid choice when the contract needs a formal but approachable tone.
Century Schoolbook edges ahead if you want the most universally accepted option.
When a Sans-Serif Font Is the Better Call
Sans-serif fonts lack the small finishing strokes and look cleaner on screens. If your contract will primarily be read on laptops, tablets, or phones rather than printed, a sans-serif font can improve clarity at smaller display sizes. Good choices include Arial, Calibri, Verdana, and Helvetica. Verdana was specifically designed for screen legibility, with wide spacing and large letterforms that hold up at low resolutions.
The Seventh Circuit’s rules permit sans-serif fonts in headings and captions even where body text must be serif, which points to a practical hybrid: a serif font for the body of the contract and a sans-serif font for section headings, creating visual contrast.2United States Court of Appeals for the Seventh Circuit. Practitioner’s Handbook for Appeals If the entire contract lives on screen, Calibri at 12 or 14 points is a clean default that most readers already encounter in everyday documents. Sans-serif fonts also tend to be easier to distinguish for readers with low vision or dyslexia, which is worth considering for any contract going out to a broad audience.
Why Times New Roman Is Not the Best Choice
Times New Roman is the most common font in legal documents and one of the worst for extended reading. It was designed in the 1930s for the narrow columns of the Times of London, so its characters are compressed to save horizontal space. That compression makes it harder to read at the full-page line lengths typical of a contract.
The Seventh Circuit’s typography handbook explicitly advises against Times New Roman, noting its small x-height and narrow character widths make it a poor fit for document-length text.2United States Court of Appeals for the Seventh Circuit. Practitioner’s Handbook for Appeals People use it because it is the default in Microsoft Word, not because it is the strongest option. Switching to Century Schoolbook or Garamond costs nothing and produces a noticeably more readable document.
What Size the Font Should Be
Twelve-point type is the practical minimum for contract body text, and it is also the threshold most courts and regulators treat as the baseline for readable legal documents. Fourteen points improves readability further, particularly for digital contracts viewed on small screens. Below 12 points, you start creating problems for both readability and enforceability.
Federal Size Rules
Some federal regulations specify exact font sizes for disclosures in consumer-facing contracts. Under Regulation Z (Truth in Lending), the annual percentage rate on credit card applications must appear in at least 16-point type, while other required disclosures need a minimum of 10-point type to meet the “readily noticeable” standard.3eCFR. Part 226 – Truth in Lending (Regulation Z) Employee benefit plan descriptions under federal law do not specify a point size, but they must be written in a manner calculated to be understood by the average plan participant, and any limitations or restrictions on benefits must appear in type no less prominent than the text describing the benefits themselves.4eCFR. 29 CFR 2520.102-2 – Style and Format of Summary Plan Description The FTC has noted that disclosures too small to read on a mobile device without zooming do not qualify as clear and conspicuous.5Federal Trade Commission. .com Disclosures: How to Make Effective Disclosures in Digital Advertising
State Size Rules
Many states impose their own font size floors for specific contract types. Insurance policies are the most common target. A majority of states require policy text to be printed in no less than 10-point type with one-point leading between lines, and several states push specific disclosures to 12 points or larger.6National Association of Insurance Commissioners. Readability Requirements Some states extend similar requirements to service contracts and vehicle warranty agreements. If you are drafting a consumer-facing contract, check whether your state sets a size minimum for that document type. Violating it can give the other side grounds to challenge the agreement.
A Working Default
Use 12-point type for body text as a baseline. Footnotes can go as small as 10 points, but anything below that risks both readability complaints and legal scrutiny. For digital contracts, 14 points is the comfortable choice.
Making Disclaimers and Key Terms Stand Out
Certain clauses only hold up if they are conspicuous, meaning written so that a reasonable person would actually notice them. This matters most for warranty disclaimers, liability limitations, and arbitration clauses. The Uniform Commercial Code, adopted in some form by every state, defines a term as conspicuous if it appears in a printed heading in capitals, in larger type than the surrounding text, or in a contrasting type or color. Whether a term meets that standard is ultimately a question for the court.
The instinct most drafters follow is to put these clauses in all caps. That satisfies the UCC test, but it creates a different problem. Blocks of capitalized text are significantly harder to read than mixed-case text, because every word in all caps forms the same rectangular shape and strips away the visual cues readers use to recognize words quickly. Screen readers also misinterpret all-caps words as acronyms, which makes the clause inaccessible to visually impaired users.
A better approach is to use bold text at the same size as the surrounding body, or to increase the font size by two points for the critical clause. Either technique satisfies conspicuousness requirements while keeping the text readable. If your organization or counterparty insists on all caps, limit it to short headings like “LIMITATION OF LIABILITY” and write the clause text itself in bold mixed case.
When Font Choices Affect Enforceability
Courts have increasingly treated tiny, hard-to-read font as a factor in procedural unconscionability, the doctrine that looks at whether one party had a meaningful opportunity to understand and negotiate the terms. Small, blurry text packed into dense paragraphs contributes to the element of surprise that makes an unconscionability finding more likely. In practice, a court that finds high procedural unconscionability from illegible formatting will require the challenging party to show less substantive unfairness to void a clause.
Font size alone will not make an otherwise fair contract unenforceable. But combined with other factors, like a take-it-or-leave-it adhesion contract, unequal bargaining power, or complex terms buried deep in the document, cramped type becomes ammunition for the other side. The fix is cheap: use 12-point type, keep paragraphs to a reasonable length, and put important terms in bold or a slightly larger font. No court has ever penalized a drafter for making a contract too easy to read.
Spacing and Structure Around the Font
Font selection only does half the work. How you space and structure the text matters just as much.
Set line spacing between 120% and 145% of the font size. For 12-point type, that corresponds to something between single and 1.5-line spacing in most word processors. Double spacing is common in court filings but unnecessary for contracts; 1.15 to 1.5 spacing reads more naturally and keeps the document from ballooning in length. Margins of one inch on all sides prevent a cramped appearance and leave room for annotations.
Clear headings do more for contract readability than any font upgrade. Use a visual hierarchy with larger or bold headings for major sections and smaller or indented headings for subsections. The Seventh Circuit recommends against using bold or all caps for extended headings, since both impair readability in longer passages.2United States Court of Appeals for the Seventh Circuit. Practitioner’s Handbook for Appeals A bold heading of a few words is fine; a bold heading that runs three lines works against you. Numbered sections and lettered subsections help both parties reference specific provisions during negotiation and in any later dispute.
For emphasis within body text, use italics for gentle emphasis and bold for the rare clause that truly demands attention. Underlining is a leftover from the typewriter era and should be avoided, because it obscures the descenders on letters like “g” and “p.” The single most important discipline with emphasis is restraint. If every other sentence is bold, nothing stands out.
Fonts to Avoid Entirely
Some fonts have no place in a contract. Comic Sans, Papyrus, and other novelty typefaces undermine the document’s credibility before anyone reads a word. Courier and other monospaced fonts reduce reading comprehension compared to proportional fonts because they space every character identically, making word shapes harder to recognize.2United States Court of Appeals for the Seventh Circuit. Practitioner’s Handbook for Appeals Condensed or narrow variants, even of otherwise good fonts like Helvetica Condensed, squeeze characters together and make dense contract text harder to parse. Script fonts that mimic handwriting are illegible at small sizes and signal informality in a document meant to bind parties to legal obligations.
If you default to one rule, make it this: pick a font designed for reading books, set it at 12 points, and leave it alone. The best contract typography is the kind nobody notices, because the reader is too busy understanding the terms.
