This size of hole punch is regarded as the gold standard of hole punches. It punches two holes at a time, which are a distance of 80mm apart, which is the equivalent of 8cm, or 3.15 inches. The holes should be 12mm or half an inch from the edge of the paper. The hole is usually punched at a diameter of 6±0.5 mm depending on the manufacturer. The type of hole punch you need can also be determined by the size of paper you are using since different variations of hole punch are specifically targeted at particular paper sizes, such as letter-sized paper, legal-sized paper, and A4-sized paper.

There are many different types of ring binders, with different amounts of rings and different spacing measurements between the rings, and this means that several different sizes of hole punch are required.a b "PK-520 Punch Kit Installation Manual".

The hole punch comes in various standard sizes including the ISO 838 (with 2 holes apart), 3-hole, 4-hole 888, 4-hole legal, and single punch. It typically has a diameter of 6±0.5 mm and there are 80 – 108mm between holes depending on the manufacturer. hole system exists. It is still in use today, but is not as common as the 3-hole standard. The four holes are positioned symmetrically with centers 3 + 1⁄ 2 inches (89mm) apart. The four binding positions provide more support for the longer 14-inch side of legal paper.

International Standard ISO838 specifies two holes, with centers 80 ±0.5mm apart, and located 12 ±1mm from the nearest edge of the paper, and with the pair of holes positioned symmetrically along that edge. Each hole is to have a diameter of 6 ±0.5mm. Any paper format that is at least 100mm high can be filed using this system (e.g., ISO A7 and larger). A printed document with a margin of 20–25mm will accommodate ISO838 filing holes. The essential parts of a hole punch are the handle, the punch head, and the die. The punch head is typically a cylinder, with a flat end called the face. The die is a flat plate, with a hole matching the head. The head can move, while the die is fixed in place. Both head and die are usually made of a hard metal, with precise tolerances. One or more sheets of paper are inserted between the head and the die, with the flat face of the head parallel to the surface of the sheets. Moving the handle pushes the head straight through the sheets of paper. The hard edge of the punch vs the die cuts a hole in the paper, pushing the cut piece out the bottom of the die. The cut-out bit of paper scrap is called a chad. A variety of hole patterns are in use for ring bindings. In much of the world, two-hole and four-hole punches consistent with ISO 838 are the norm. In the US, the three-hole punch is most common. See §Standards. In Sweden, a four-hole national standard [7] is almost exclusively used. The centers of the holes are 21mm, 70mm and 21mm apart, 10.5 ±0.5mm from the edge of the paper. The guides help keep the paper in a straight line.Most people are familiar with a hole punch, which also goes by the names of the hole puncher, and paper puncher.

Single-hole punches can also be used for binding, with a single loose binding ring, although this is much less common than with ring binders. There are hole punches which punch patterns of multiple holes at once, typically for binding multiple sheets together (see §Applications). Such punches generally feature two paper guides for alignment. One guide will be along the side of the paper to be punched, and sets the distance of the holes from the edge of the paper (the margin or gutter). The other guide will be on a perpendicular side, and aligns the holes between the top and bottom of the sheet. One or both guides may be adjustable.
