How to Fold a Fast-Flying Paper Airplane

Start with a flat sheet of paper. Place the paper on a flat surface in front of you. Choose a sheet that is free of creases or wrinkles, as these can hinder the airplane's flight performance once completed. Initially, use larger paper for easier folding before experimenting with other sizes.

• Folding from top to bottom is easier.
• For the instructions below, standard letter-sized paper measuring 21x30 cm (equivalent to A4) works best.

Fold the paper in half vertically, then unfold it. Rotate the paper lengthwise and fold it down the center. Ensure the top corners align with the bottom edges of the paper. Run your thumbnail along the fold to crease it, then unfold slightly so the paper forms a slight ‘V’ shape.

• The center fold will serve as a guide for subsequent folds.
• You can also fold the paper widthwise if preferred. This fold will guide the vertical folds.

Fold the top two corners down. Bring both top corners of the paper down to align with the center fold. Press firmly to secure the creases. The folded corners will form a large triangle at the top of the paper.

Fold the top triangle down. Fold the triangle created by the top corners downward. The paper will now resemble an envelope, with a square at the bottom and a pointed triangle at the top. This will form the body of the airplane.

• Leave a gap of about 5-7.5 cm between the tip of the triangle and the bottom edge of the paper.
• Folding the paper down reduces its size and increases thickness, adding weight to help the airplane fly farther.

Fold the top corners down so the edges meet at the center. Carefully fold the top corners again to align with the center crease. Leave a small portion of the previously folded triangle exposed, creating a small triangular tab below the new fold. This tab should be about 2.5 cm long.

• The pointed tip at the top of the paper after the final fold will become the nose of the airplane.

Fold the triangular tab up. Fold the small triangular tab over the previously folded section to lock the edges in place. Ensure the tip of the small triangle aligns with the center crease. This fold is crucial as it maintains the airplane’s shape and balance during flight.

• This technique, using the triangular tab to secure the fold, is known as the "Nakamura Lock," named after the designer who popularized it in origami.

Fold the paper outward to form the body of the airplane. Now, fold the paper in half outward, opposite to the initial center fold. The triangular section folded underneath will add weight and stability to the airplane. You’ll also see the final size and shape of the airplane taking form.

• When folding the paper outward, the triangular section will wrap around the belly of the airplane, preventing it from unfolding and creating a convenient grip for launching.

Make the final folds to create the wings. Lay the airplane on its side and fold the paper down so the top edge aligns with the belly of the airplane. Flip it over and repeat the fold on the other side to form the wings. Press firmly to secure the creases. Your airplane is now complete!

• Be careful not to bend the wings while folding.
• Find an open space to launch your airplane. This design ensures it flies far, straight, and can reach impressive speeds.

Adjust the nose of the airplane. A simple modification to this design is creating a blunt nose instead of a pointed one. To achieve this, leave about 1.3 cm on either side of the center fold when folding the corners, which will later be secured by the small triangular tab. The corners will be folded diagonally to leave a flat front.

• Blunt-nosed airplanes fly slightly slower but cover greater distances due to improved aerodynamics.

Ensure the airplane flies straight. If the paper airplane veers too much to one side, it’s often due to uneven wings. Double-check the wing folds and ensure both wings are flat, symmetrical, and of equal height. Make minor adjustments, as excessive folding can soften the paper and reduce lift.

• Some slight curving during flight is normal, so only adjust the wings if the airplane spirals out of control.

Prevent the airplane from nosediving. If the airplane tends to dive toward the ground, the issue might lie in the wingtips. Slightly curl the wingtips upward to catch air as the airplane moves forward. A small curve can make a big difference, so avoid overdoing it to prevent warping the wings.

• Paper airplanes operate on the same physical principles as real airplanes. A slight curve on the wings is essential to convert air resistance into lift.
• Try folding a blunt-nosed airplane if yours tends to nosedive. A pointed nose is more prone to damage upon impact.

Maintain consistent lift. Another common issue is the airplane looping upward before stalling. The solution is the opposite of the nosedive problem: gently curl the wingtips downward until the airplane flies straight. Test it a few times to ensure the issue is resolved before attempting longer flights.

• If you throw too hard, the nose might tilt upward, causing the airplane to stall. Use a smooth, straight arm and wrist motion for a stable flight.

Select paper with the appropriate weight. For an airplane to fly high and far, use paper that is neither too light nor too heavy. Standard A4 letter paper (21x30 cm) is ideal in terms of size, weight, and thickness for folding a plane that can fly dozens of meters. Thinner paper, like newsprint, doesn’t catch air well, while cardstock, construction paper, and other thick materials create too much drag and are harder to fold. However, paper isn’t the only option. Cardboard with the middle layer removed can also be used for folding airplanes if needed.

• Office paper—stiff, smooth, and of moderate thickness—often makes excellent airplanes.
• Thinner paper can be used for smaller planes, as the compact size compensates for the weight difference. Similarly, thicker paper works well for oversized planes.

Ensure the use of standard-sized paper. Until you master the folding technique, avoid using paper with unusual dimensions. Most paper airplane instructions assume the use of A4 paper (21x30 cm). Changing the length or width of the paper can significantly alter the airplane’s performance, and it may not fly at all if it’s too long or too wide.

• If using recycled paper, cut or tear it to match the proportions of letter paper, then adjust the folding scale accordingly.

Use paper that holds creases well. Another advantage of medium-weight paper, such as letter paper or office paper, is its ability to maintain sharp folds. This is especially important if you want your airplane to fly fast and far, as sloppy or uneven folds can reduce its aerodynamic efficiency. Generally, the smoother the paper, the better it holds creases. Avoid soft, porous, or textured paper, as these types won’t produce crisp folds.

• Rough paper, metallic paper, laminated paper, and glossy paper don’t hold creases well.
• Run your fingernail over each fold multiple times. The sharper the crease, the better the airplane will retain its shape.

• Always hold the nose of the airplane to avoid damaging the wings.
• Test-launch in an open area to prevent the airplane from hitting obstacles.
• For the best flight, throw the airplane forward and slightly upward at a low angle.
• Use fresh paper for folding; avoid reusing previously folded paper.
• If you make a major mistake while folding, start over with a new sheet.
• Consider using a ruler to ensure precise edges and folds.
• When folding, always use the right type of paper and work on a flat surface to ensure the airplane has a solid structure for fast and long flights.
• Choose the correct paper—avoid overly thin paper like tissue paper. Craft paper (if thin enough) is a good option for folding airplanes.

• Avoid letting the airplane collide with objects. Once bent or damaged, a paper airplane may not fly as well as before.
• Paper airplanes can be ruined if they get wet.
• Do not throw paper airplanes at people, especially those with pointed noses.
