This flat diamond from Amazon is a typical retail diamond that anyone can fly down at the beach, on it's single line. Made from durable materials that can take a bit of rough-and-tumble. Reliable in the air, once you get that tail off the ground.

Some people refer to Diamonds as '2 stick kites'. The two sticks
are the vertical spar running from nose to tail, and the horizontal or 'cross' spar
going side to side.
Although not often seen now, the Diamond kite design can be flown with a bowed
cross spar. If positioned close enough to the nose, this eliminates the
need for a tail.
The bow can be achieved by tensioning the spar with string, causing it flex. Alternatively, the cross spar can be in 2 pieces with these then joined to the vertical spar at an angle. This is called dihedral.
Back in Victorian times, the arch-top kite was popular. This design looked and flew very much like a diamond, except that the upper 2 edges were replaced with a single curved piece. Like an arch and hence the name.
When the weather's good and you have the time, it's great to get out with a kite or 3. But what about on bad weather days? Then it's time to pull out...

I certainly made a few classic flat Diamond kites as a kid, like many people! Being rather heavy, none of them flew as well as the ones I make these days.
Diamonds are simple to make, which used to make them a popular DIY choice for children or beginners. Most people these days prefer to buy though, since simple kites are quite inexpensive.
There's not a whole lot of variation in the basic make-up of Diamond shaped kites, but here's what I can tell you...

- overall size varies of course, although most Diamonds are less than a meter (3 feet) tall
- the cross spar might cross nearly in the center, making an almost
square shape, or it might cross close to the top of the kite for a more
classic Diamond shape
- construction can be with or without a line threaded around the tips of the sticks, forming a Diamond outline
- all flat Diamonds need a tail, but this can be a flat ribbon,
several thin flat ribbons, a line with bows, or just about anything that
streams out and drags in the wind
- decoration of home-made kites takes many forms and shop-bought kites are also available in colorful designs
- with the cross spar bowed enough and mounted high enough on the vertical spar, a Diamond is stable enough to fly without a tail
- the bridle is traditionally attached to the kite in 2 places on the
vertical spar, and not necessarily at each extreme end of the spar
- traditionally, the sail was paper but these days plastic, nylon or polyester is common
By the way, I'm not covering 2-line diamond stunt kites here! This page is strictly about the single-line variety.
Here's a few comments on each of the above points.
Size. Some kite flyers just love to show off with huge
kites, and I've read about a few rather large Diamonds too. Anything
over a couple of meters tall (7 feet) is pretty big! On the other hand, a
Diamond kite is a popular choice for makers of miniature kites. These
can be as small as the palm of your hand or even smaller, and can be
flown on ordinary sewing thread.
Shape. The picture at the top of this page shows an
almost-square kite. My MBK design is more traditional, with the cross
spar exactly 1/4 of a spar length from the top of the vertical spar. As
far as I am aware, the cross and vertical spars are exactly the same
length in most Diamonds.
Construction. For flimsy materials such as paper, many
Diamond kites are constructed with a line around the tips of the kite
spars. This forms a Diamond outline to which the sail material can be
folded over and attached. My MBK kites are just fine without it, since
the edges are reinforced with tape to provide resistance to stretching
and tearing. It's simpler, too, and simpler is nearly always better!
Tails. These are only limited by your imagination really,
but the most common types are a single ribbon, multiple ribbons or a
line with cloth or paper bows tied into it at regular intervals. For my
skewer-based MBK Diamonds, I have tied loops of light plastic together,
forming a chain. Works well! Decorative tassels or tails can be attached
to the ends of the cross spar as well.
Decoration. Strips of different colored material can be
joined together before the outline is cut. The appliqué technique
involves sticking light but colorful cut-out patterns onto the sail
material. Printed sail material can be used. Hand painting or
airbrushing can be applied after the kite is constructed. There's a
bunch of different ways to decorate a kite! The bigger the kite, the
less difference the extra weight of decoration makes to its light wind
performance. Shop bought Diamonds are available in a huge variety of
Bowed. Just about any flat kite will fly in a more stable
way with a bow built into it. The Diamond kite is no exception. With the
cross spar bent back, away from the flying line, the kite will require
less tail to fly successfully. With enough bow, no tail is necessary at
all. A lightly constructed flat Diamond will sometimes bow a little anyway, in strong wind, thus giving itself a little more stability.
Bridle. If you attach the flying line in exactly the right
spot, you can just tie it directly to the vertical spar. However, the
more usual approach is to make a bridle by attaching a length of line to
each end of the vertical spar. Or, as in the MBK Diamond, 2 points
somewhere in between. The flying line is then attached to the bridle. By
adjusting exactly where the flying line attaches, the kite can be made
to fly nicely in a range of wind conditions.
Sail. The earliest kites used paper, but rip-stop nylon
would be the most common choice these days. To save money, plastic sheet
from various kinds of bags can be used on small to medium sized kites
as well. Sheets of Mylar is another option. My freezer bag kites can be a
bit hard to see, but magic happens near sunset, when the sun's rays
glitter and glisten off the clear plastic!

Diamond Kites In Action
Here's an interesting shot of a train of small Diamonds. Just one of the kites has turned enough to catch the sun, and display its decoration...
Over the centuries since Diamond kites were first popular in Europe, they have been used for many
For example, aerial photography, meteorological
observations and the transmission of long-range radio signals. In this
regard, their history has a distinct similarity to the history of Box
kites. Only Box kites came along much later, since the late 1800s, and did all these things better!
But what are diamond kites used for in the new Millennium? Just having
fun, it seems!
Apart from a handful of hobbyists perhaps, the great
majority of Diamonds these days are relatively small, colorful kites
mainly marketed to children. That doesn't stop a few older kite nuts
like yours truly flying them as well!
There is no end to the variety of decoration on the mass-produced
Diamond kites. Actually, not all are mass produced...
A small percentage
of the market is still supplied by dedicated and skillful kite-makers
who offer true flying works of art. These custom kites cost a bit more,
Due to the simplicity of the 2-stick kite, many people still make
them from scratch at least once in their lives. One of these kites can
be made quite sloppily and yet still be expected to fly, with some
experimentation with the bridle attachment point. That's the beauty of a
simple Diamond kite.
The big Carbon Diamond (2m) on Monday at the recent AIKF 2016. In the very on-and-off easterly during the morning, it had a habit of doing touch-and-go's off it's tail on the damp sand...Posted by My Best Kite on Monday, April 4, 2016
The large kite in the video is inspired by the classic Eddy tail-less Diamond, but I made it made from modern materials. Carbon fiber tube and hard Tyvek (house-wrap) for the sail.
Some Diamond Kite History
In terms of the structural design of Diamond kites, there's not much to say. It just hasn't changed much for centuries! But very broadly speaking, these kites have seen 3 phases over time.
- recreational since the 1600s!
- a period of more serious applications during the mid 1700s to early 1900s
- back to recreational again, ever since the early 1900s
Out In The Field
Diamond kite stories of my real-life flying experiences are worth checking out!
Illustrated with photos and videos, of course.
On that first point, there is apparently an illustration in an old document that proves this. The book dates to 1618,
and shows children flying Diamond shaped kites in the town of
Middelburg, Holland (now The Netherlands). It's fairly safe to assume
that such kites were flown in various parts of Europe right into the
A lot could be written about the scientists in the 1700s and
1800s who used kites for various purposes. Benjamin Franklin's famous
experiments with kites and electricity were performed in the mid 1700s.
We know he used a Diamond kite from the text of a letter he wrote in October 1752.
In it, he described how to make a kite from a 'large, thin silk
handkerchief' and 'a small cross of two light strips of cedar'.
Later, William Eddy, also from the United States, made important
contributions to the use of kites for scientific purposes. Eddy
experimented with tail-less Diamond kite designs, flown in trains. That
is, all linked together in line. These kite trains, or stacks as they
are sometimes known today were used to hoist meteorological instruments
to high altitude. By 1892, all his kites featured the bowed
cross-spar that enabled them to fly without tails. The 'Eddy Diamond'
did a lot to make the Diamond shape kite very popular and recognizable
in the Western world at that time.
However, the Box kite and other related kite designs proved
better for lifting work. Hence after Hargrave from Australia invented
his Box kite in the late 1800s, the Diamond kite quickly faded away from
the scientific scene.
In the third point above, I said 'back to recreational'. But really, Diamond kites were probably always
being flown for fun, regardless of what other uses people found for
them. The popularity of this type of kite has not always remained steady
from decade to decade. However, to this day it's always been possible to find someone, somewhere, flying a Diamond kite!
In the video up there is our MBK Dowel Diamond design, doing it's thing in light winds.
As mentioned earlier, there's another alternative to towing indoor kites if it's just not possible to fly outdoors...
