How much evidence is needed for a trial?

The amount of evidence needed for a trial depends on the case type, but the standard is high: criminal cases require proof "beyond a reasonable doubt" (near certainty of guilt), while civil cases need a "preponderance of the evidence" (more likely than not, or >50% likely). Evidence must be admissible and reliable, forming a convincing narrative for the judge or jury, with specifics like witnesses, documents, photos, or expert testimony used to meet these standards, rather than a fixed quantity.
