Developments

Paper gliders have experienced three forms of development in the period 1930–1988:

- High flight performance

- Scale modeling

- Use of CAD software

Ongoing development of folded/origami gliders over the same period has seen similar sophistication, including the addition of the following construction refinements

- Increased fold-count, sometimes of an intricate nature

- Explicit kirigami (cutting of paper) as a component of design

- Requirements for additional ballast to ensure flight performance

Technological introductions

Technology responsible[citation needed] for the proliferation of advanced paper plane construction:

- Inexpensive CAD software for 2D part design

- Widespread manufacture, and inexpensive nature of acetal air-annealed glues, e.g. Bostick Clear-bond.

- Inexpensive ink and laser computer printers, for accurate aircraft part reproduction

- The advent of the Internet, and widespread information sharing

Material considerations

Compared to balsa wood, another material commonly used to fabricate model planes, paper's density is higher; consequentially, conventional origami paper gliders (see above) suffer from higher drag, as well as imperfectly aerodynamic wing chords.

However, unlike balsa gliders, paper gliders have a far higher strength-to-thickness ratio – a sheet of office-quality 80 g/sq m photocopier/laser printer paper, for example, has approximate in-scale strength of aircraft-grade aluminium sheet metal, while card stock approximates the properties of steel at the scale of paper model aircraft.
