How To Build A Delta Kite

Step-by-Step - The MBK Simple Delta

Learn how to build a Delta kite with these easy-to-follow instructions. Fully illustrated with photographs, every step of the way.

Don't worry about how long this page looks...

The steps are easy, hence this simple Delta kite comes together very quickly!

We still take out the Simple Delta occasionally. As long as the wind isn't too strong, it's as much fun as any similar-sized shop Delta. It hovers at a steep angle on the end of our Dacron flying line.

Let the line out to 90 meters (300 feet) or more, if you want to! Or, down at a beach in a sea breeze, this kite will hover reliably on quite a short line. Put some sand into a bag to act as an anchor.

The kite does best in quite light wind, so be prepared to add some more tail if you're trying to fly in a fresher breeze.

Making Dowel Kites is an e-book that's worth a look (or printing off) when you want to explore bigger and better kites. Using similar materials and construction methods - that is, just dowels, plastic and tape.

Such a simple kite and yet it flies so high in a light breeze. The video above shows this kite coping with fresh gusts that are nearly too strong for it.

1. How To Build A Delta Kite -
Measuring The Sail

You might want to take a quick look at the materials and tools for making this kite, first. Then just click the Back button on your browser to get back here.

The Simple Delta - measuring the sail.
  • Place your plastic bag flat on the floor, with the closed end at the top.
  • Starting from just below the top-left corner of the bag, measure and mark 3 dots on the plastic. I've high-lighted the dots in yellow, in the photo. Judge the horizontal direction by eye. If you're careful, there's no need for a T-square.

2. How To Build A Delta Kite -
Cutting The Sail

The Simple Delta - marking the template shape.
  • Take your ruler and connect the dots with the black marker pen, as shown in the photo. (OK, the lines appear a bit faint in the photo!)
  • Flip the plastic over and trace over all the black lines.

The Simple Delta - the complete outline on plastic.
The Simple Delta - the sail cut out and edged with tape.
  • Cut along the top and right side of the bag, and open it out to show the complete sail outline, as in the photo above.
  • Take your scissors and cut along all the black lines. As in the photo over there on the right, your Delta kite sail is nearly complete!

  • Take some 5mm (3/16") dowel and cut off a 70 cm (28 inch) length. Lay this down the center line of the sail.
  • Now cut off 2 more lengths, each 80 cm (32 inches) in length. Lay these down over the leading edges of the sail.
  • Using 6 pieces of insulation tape, each 5 cm (2 inch) long, stick them down in the positions shown in the top left photo, above.
  • Fold all the tapes around to the underside of the plastic. See the top right photo, above.
  • Cut off a 70 cm (28 inch) length of dowel and lay it across the sail, 31 cm (12 1/4 inches) from the nose. Using 2 pieces of insulation tape, each 20 cm (8 inches) long, lay them over the crossing points. See the top photo, in the group of 3.
  • Carefully wind the tapes around the dowels, without getting them stuck to the sail! Now, each join should look like the middle photo on the right.
  • Add an extra tape to the middle of each leading edge, to help keep the sail in place. Also tightly wind an 8 cm (3 inch) piece of tape around the spar join. See the bottom photo on the right, which was actually taken after some test flying in strong wind!

4. How To Build A Delta Kite -
Attach The Flying Line

Try this Stake Line Winder from Amazon, if you are not sure where to get suitable flying line. The 30 pound strength is ideal for the Simple Series or Soft Series kites.

The Simple Delta - attaching the flying line.
  • Get your flying line, which I'm assuming has been wound onto a spool or winder of some sort.
  • Poke a hole in the plastic sail, right over where the horizontal and vertical dowels cross each other.
  • Thread the flying line through the hole, and tie it firmly around the vertical spar. Do NOT tie it around the horizontal spar! This dowel floats free while the kite flies.

5. And Finally - Attach The Tail

The Simple Delta - attaching the tail
  • From spare scraps of sail plastic, make up a long narrow strip no shorter than 4 times the length of the kite itself. The strip should be about 5 cm (2 inches) wide.
  • Thread one end of the tail around the bottom of the vertical spar, as you can see in the photo. Tie the tail to the dowel with a simple knot.

Hope you enjoyed learning how to build a Delta kite! Up there is another shot of our original Simple Delta doing it's thing on a cloudy day with plenty of sun and just enough wind to keep the kite flying.

Out In The Field

Delta kite stories of my real-life flying experiences are worth checking out!

Illustrated with photos and videos, of course.

That's it, you're ready to fly. Take the kite out whenever you can see leaves moving in the trees or bushes.

If the kite won't stay up, try letting out plenty of line and then towing it up at jogging pace. It might find enough wind higher up!

Avoid flying in very windy weather.

Ever Made This Kite?

You've probably read a kite-flying story or 2 of mine, after they appear under the "what's new?" link on this site. I sometimes wonder if anyone else has made and flown this particular design...

If you feel your efforts really paid off when the the kite finally got airborne - please type a few paragraphs in here telling us all about it!

P.S. I can only accept stories of at least 300 words. Just mention a few details like the weather, onlookers, the kite's behavior and so on - 300 words is easy!

"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world.

Very satisfying making your own and watching them get air-born for the first time."


"I decided to run kite making as an elective again on this camp in the past week - so I bought all your e-books, a bunch of materials, and then took a group of 10 high school students through making the kites over 4 days. We built a diamond, a Barn Door, a Delta, and two skew delta kites. Again - every single kite flew."


"I've just bought your super e-book and spent most of last night pouring through all the great stuff in it!

Very detailed and USEFUL information - thanks for such a great book."


"30+ years ago, I tried making a kite using the 'instructions' in a free kite-safety booklet. What a disappointment for a young boy.

 Your instructions and methods are wonderful. You help the builder to focus on accuracy, without making it hard. Also, you use materials that are durable, yet cheap!"


"omg i made a kite from this site and i fly it ....... booom i didnt expect this bc in the other sites instuction are trash
