OPINION
Patrick Tillio, proceeding pro se, appeals the decision of the District Court dismissing his complaint without prejudice for failure to comply with Rule 8(a) of the Federal Rules of Civil Procedure. In January 2011, Tillio filed a five-page handwritten complaint. On January 20, 2011, the District Court, sua sponte, dismissed Til-lio’s complaint without prejudice and closed the case statistically, because it was “rambling and unclear” and therefore failed to meet the pleading standards set forth in Rule 8(a).
We have jurisdiction over this appeal pursuant to 28 U.S.C. § 1291. This Court reviews a district court’s dismissal of claims under Rule 8 for abuse of discretion. In re Westinghouse Sec. Litig., 90 F.3d 696, 702 (3d Cir.1996).
Federal Rule of Civil Procedure 8(a) requires a pleading to contain “a short and plain statement of the claim showing that the pleader is entitled to relief.” A district court may sua sponte dismiss a complaint for failure to comply with Rule 8, but dismissal “is usually reserved for those cases in which the complaint is so confused, ambiguous, vague, or otherwise unintelligible that its true substance, if any, is well disguised.” Simmons v. Abruzzo, 49 F.3d 83, 86 (2d Cir.1995) (quotations omitted). Although the complaint Tillio submitted was, as the District Court noted, “rambling and unclear,” district courts generally must allow plaintiffs leave to amend deficient complaints prior to dismissal unless doing so would be futile. Simmons, 49 F.3d at 87; cf. Grayson v. Mayview State Hosp., 293 F.3d 103, 108 (3d Cir.2002).
We conclude that the District Court did not abuse its discretion in dismissing Til-lio’s complaint for failure to comply with Federal Rule of Civil Procedure 8. None of his submissions to the District Court or to this Court reveals any factual or legal basis for a federal claim. Although a district court should generally give leave to amend prior to dismissing or making its own determination whether any amendment would be futile, Simmons, 49 F.3d at 87, we are satisfied — especially in light of Tillio’s unclear appellate filings — that the District Court did not abuse its discretion by dismissing his complaint without leave *111to amend. Cf. Grayson v. Mayview State Hosp., 293 F.3d 103, 114 (3d Cir.2002).
For the foregoing reasons, we shall affirm the judgment of the District Court.
