The easiest paper to start with is often the sheet already in your printer. Ordinary office paper keeps the material familiar while you learn to make even folds. Once you have a design that flies consistently, changing the paper becomes an experiment you can interpret rather than another unknown.
Use one size while learning a design
Letter paper measures 8.5 × 11 inches; A4 measures 210 × 297 mm. They are close in size but have different proportions. The same sequence of folds therefore does not produce precisely the same wing outline or nose length. Neither size is automatically better.
Use the same sheet size for a set of comparison flights. If you switch sizes, refold the whole plane and label it. In the app, choose the correct size before folding so the step measurements and simulated sheet match your real paper.
| Paper | Useful characteristic | What to check |
|---|---|---|
| Printer paper | A straightforward starting point for crisp folds | Keep the sheet dry and avoid wrinkled corners |
| Notebook paper | Easy to find and mark with flight notes | Remove torn edges; check whether the wings sag |
| Construction paper | Easy to see and distinguish between planes | Thick layered folds may not close cleanly |
| Cardstock | Stiffness can help a simple wing hold its shape | Weight and bulky folds can change the balance substantially |
Weight and stiffness are different things
The number marked “gsm” on a package means grams per square meter. It describes mass per area, not the finished plane's strength or flight distance. Two sheets with similar gsm can behave differently when folded because their stiffness and surface finish differ.
A heavier sheet makes a heavier plane of the same outline. It may need a different launch and trim. A stiffer sheet may hold a crease or wing angle better, but the thickness can stop a tight lock from closing. Do not assume that “heavier” means “farther” or that “lighter” means “longer in the air.” Compare repeatable flights.
Check how the sheet wants to bend
Paper can bend more readily in one direction than another. Gently curve a spare sheet lengthwise and crosswise without creasing it. Notice the difference in resistance. For your first plane, simply keep the sheet orientation consistent; advanced comparisons can treat that direction as another variable.
Humidity, repeated crashes, and handling also change a sheet. A plane that has flown into a wall ten times is no longer a fair partner for a fresh plane. If you want to compare two materials, start with fresh sheets and apply the same folding care to each.
A simple two-paper comparison
- Choose one design and one sheet size.
- Fold two planes using two different paper types, with no clips or tape.
- Label them A and B on the body, away from the wing edges.
- Alternate five throws each in the same space.
- Record distance, visible flight pattern, and damage. Compare the middle result for each plane rather than only the best throw.
If the folds are much bulkier in one material, record that too. Your result describes the combination of material and design, not a universal ranking of every kind of paper. The flight test guide provides a recording sheet and a method for keeping the comparison fair.
