What is the actual target length?
One page. If you are typing, that means roughly 200 to 400 words. If you are handwriting, it means the front of one sheet with normal spacing. A brief that runs to two pages is no longer a brief — it is a transcript of the opinion, and you will not reread it.
The time budget matters more than the word count. Aim for 10 to 15 minutes per case after you have read the opinion. If briefing is taking 45 minutes a case, you are copying rather than compressing, and you will run out of hours in the first month of the semester.
The test of a good brief is functional, not aesthetic: can you answer a cold call from it without looking at the casebook, and can you pull a usable rule statement out of it six weeks later when you build your outline? If yes, it is long enough. Everything past that is wasted.
How should the words be distributed across sections?
Most students overweight facts and underweight rule and reasoning. Flip that. Facts are what you will remember anyway; the rule and the court's justification for it are what appear on the exam. Here is a workable budget for a full-page brief:
- Citation: one line. Full Bluebook form under Bluepages B10.1.1 — e.g., Int'l Shoe Co. v. Washington, 326 U.S. 310 (1945), or Palsgraf v. Long Island R.R. Co., 162 N.E. 99 (N.Y. 1928). Use the abbreviations in tables T6 and T10 so you build the habit before your legal writing memo is due.
- Facts: three to five sentences. Only outcome-determinative facts — the ones that, if changed, would change the result.
- Procedural posture: one or two sentences. Who won below, on what motion, and who appealed. This is nonnegotiable in Civil Procedure and often skippable in Contracts.
- Issue: one sentence, framed with the key facts embedded. "Whether a state may exercise personal jurisdiction over a foreign corporation whose only in-state activity is systematic solicitation by salesmen" beats "whether there was jurisdiction."
- Holding: one sentence that answers the issue in the same words.
- Rule: one to three sentences. This is the part you will copy into your outline verbatim, so write it as a portable, fact-independent statement.
- Reasoning: three to six sentences. Why the court chose that rule — policy, text, precedent, or line-drawing.
- Concurrence or dissent: one or two sentences, and only if the casebook printed it or the professor flagged it.
- Your own note: one line. A question, a tension with the last case, or a hypothetical the rule cannot handle.
Should every case get the same length?
No, and treating every case equally is the most common way students waste time. Casebooks contain two kinds of cases: doctrinal spine cases that supply a rule you will apply all semester, and illustrative cases that show one application or one variation.
Spine cases get the full page. In Civil Procedure, that is Pennoyer v. Neff, International Shoe, and Erie R.R. Co. v. Tompkins. In Torts, Palsgraf and the cases establishing the negligence elements. In Contracts, Hadley v. Baxendale for consequential damages. You will be asked to apply these directly on the exam.
Illustrative cases — the three-paragraph note cases, the ones the professor introduces with "and then the court in X reached the opposite result" — get four lines: name, one fact that distinguishes it, the outcome, and why it differs from the case before it. If a case exists in the casebook only to show that the rule bends when the plaintiff is a minor, write that sentence and move on.
A useful heuristic: if you cannot articulate what work the case does in the course, you are not ready to brief it, and a longer brief will not fix that. Skim the chapter heading and the note questions first.
When should you stop writing full briefs?
Most students write full briefs for the first four to six weeks and then move to book briefing — annotating the casebook itself with a color code or margin labels (F for facts, I for issue, R for rule, and so on) plus a two- or three-line summary at the top of the case.
That transition is not laziness; it is the point. Full briefing teaches you to identify the parts of an opinion. Once identification is automatic, the written artifact adds little. Book briefing takes five minutes per case and keeps everything in one place during a cold call.
Two reasons to keep writing full briefs longer: you are still getting flustered when called on, or your professor's questioning is unusually procedural and you need the posture written out. Two reasons to switch early: you are falling behind on reading, or you are not outlining because briefing consumed the time. Outlining beats briefing on the exam every time.
What drives the variation between courses and professors?
Length expectations genuinely vary, and three things drive the variation. First, cold-call style. A professor who runs a sustained Socratic dialogue on procedural posture and asks what the appellate court would have done on different facts requires a fuller brief than one who lectures with occasional questions. Ask 2Ls who took the professor.
Second, exam format. If the exam is closed-book, your briefs feed an outline that feeds memorization, and rule statements must be tight and portable. If it is open-book, you can afford thinner briefs because you can consult the casebook. If the course is graded on a practical assignment or paper, briefing matters less overall.
Third, casebook editing. Heavily edited casebooks that print six-paragraph excerpts leave little to compress. Casebooks that reproduce twenty pages of an antitrust or constitutional opinion require real triage, and your brief will still be one page — the compression ratio just changes.
Some professors distribute a preferred brief format or tell you not to brief at all. Follow that instruction over any generic template, including this one.
What should you cut first when a brief runs long?
Cut block quotes. If you are quoting more than one sentence from an opinion, you have not understood the rule well enough to state it yourself. The exception is language your professor repeats in class — "traditional notions of fair play and substantial justice" is worth keeping in the exact words because it is a doctrinal term of art.
Cut background facts. Dates, dollar amounts, and party names rarely matter. If you would not mention it when answering "what happened here," it does not go in the brief.
Cut procedural detail that does not bear on the holding, unless you are in Civil Procedure, where the procedural detail often is the holding.
Cut alternative holdings and footnotes the professor did not assign. Cut your own restatement of the same rule in three different phrasings — pick the clearest one.
What you should not cut: the reasoning. Students routinely delete the "why" to save space and end up with a brief that is a list of results. Exam answers are graded on analysis, and analysis is reasoning applied to new facts. A brief with a rule but no reasoning cannot help you there.
