* '''Quad paper''', sometimes referred to as '''quadrille paper''' from French quadrillé, 'large square',<ref>{{cite encyclopedia |url=https://en.oxforddictionaries.com/definition/quadrille#quadrille_Noun_300 |archive-url=https://web.archive.org/web/20160924215232/https://en.oxforddictionaries.com/definition/quadrille#quadrille_Noun_300 |url-status=dead |archive-date=24 September 2016 |title=quadrille |encyclopedia=Oxford Living Dictionaries |publisher=Oxford University Press |year=2017}}</ref> is a common form of graph paper with a sparse grid printed in light blue or gray and right to the edge of the paper. In the [[United States|U.S.]] and [[Canada]], it often has two, four or five squares per inch for work not needing too much detail. In [[Europe]], it usually has 5 [[Millimetre|mm]] by 5 mm squares. It is used in mathematical [[exercise book]]s and [[Lab notebook]]s.
* '''Dot grid paper''' uses dots at intersections instead of gridlines. It is often used for [[Bullet Journal|bullet journalling]].
* '''Engineering paper''', or an '''engineer's pad''',<ref name="mit-pset">{{cite web |url=http://web.mit.edu/me-ugoffice/communication/pset-format.pdf |title=The Preparation of Engineering Problem Sets |publisher=Massachusetts Institute of Technology |agency=Technical Communications in Mechanical Engineering |access-date=25 March 2017}}</ref> is traditionally printed on light green or tan translucent paper. It may have four, five or ten squares per inch. The grid lines are printed on the back side of each page and show through faintly to the front side.  Each page has an unprinted margin.  When [[Photocopier|photocopied]] or [[Image scanner|scanned]], the grid lines typically do not show up in the resulting copy, which often gives the work a neat, uncluttered appearance.  In the U.S. and Canada, some engineering professors require student [[homework]] to be completed on engineering paper.<ref name="mit-pset"/><ref>{{cite web |url=http://eng.auburn.edu/cheweb/student/Homework_Format.pdf |title=Required Homework Format |agency=Department of Chemical Engineering |publisher=Auburn University |access-date=25 March 2017}}</ref>
* '''Millimeter paper''' has ten squares per centimeter and is used for [[technical drawing]]s.
* '''Hexagonal paper''' shows regular hexagons instead of squares. These can be used to map geometric [[Tiling by regular polygons|tiled or tesselated]] designs among other uses.
* '''Isometric graph paper''' or '''3D graph paper''' is a triangular graph paper which uses a series of three guidelines forming a 60° grid of small triangles. The triangles are arranged in groups of six to make hexagons. The name suggests the use for [[isometric projection|isometric views]] or pseudo-three-dimensional views. Among other functions, they can be used in the design of trianglepoint [[embroidery]]. It can be used to draw angles accurately.
* '''Logarithmic paper''' has rectangles drawn in varying widths corresponding to [[logarithmic scale]]s for [[semi-log plot]]s or [[log-log plot]]s.
* '''Normal [[probability]] paper''' is another graph paper with rectangles of variable widths. It is designed so that "the graph of the normal distribution function is represented on it by a straight line", i.e. it can be used for a [[normal probability plot]].<ref name="eom-prob">{{cite encyclopedia |url=http://www.encyclopediaofmath.org/index.php?title=Probability_graph_paper&oldid=11790 |title=Probability graph paper |encyclopedia=Encyclopedia of Mathematics |first=A.

* '''Polar coordinate paper''' has concentric circles divided into small arcs or 'pie wedges' to allow plotting in [[polar coordinate system|polar coordinates]].
* '''Ternary (triangular) graph paper''' has an equilateral triangle, divided into smaller equilateral triangles with usually 10 or more divisions per edge. It is used to plot compositional percentages of in systems that have three constituents or three dimensions. (see [[ternary plot]])

In general, graphs showing grids are sometimes called '''Cartesian''' graphs because the square can be used to map measurements onto a [[Cartesian coordinate system|Cartesian]] coordinate system.
