How to draw a circle with a pencil correctly. How to draw an arbitrary circle or an even circle in Photoshop

The question is important not only for beginners, but sometimes also for experienced artists. Understanding how to draw a circle correctly in perspective, we can draw a huge number of objects, not just pots and plates.
In general, a short summary: usually we rarely see round objects from the front. For example a plate like this

We see much less often than this.

Therefore, we need to understand how to correctly depict a plate in a perspective horizontal plane. There is a simple diagram for this.

The most important thing is on the left. We see ovals and the horizon line, relative to which we usually draw all objects. At the level of the horizon line, the oval either turns into a line or becomes very narrow. The higher or lower, the rounder the oval becomes, all the lines that are closer to us according to the law of perspective will be thicker, everything further away will be thinner. If the oval is much lower than the level of vision, it can become almost round. This can be seen very clearly by taking a roll of tape, your ideal medium for practicing this skill. We raise the skein to eye level - ideally we will see a rectangle, raise it higher and lower and immediately see clearly all the changes.
In the vertical plane, the story is absolutely the same, only the diagram must be turned 90 degrees.

Thus, all plates and pots become subject to us, we look at the previous picture of the plate, taking into account new knowledge.

You can draw another oval to show the thickness of the plate, the final result depends on your observation skills. The skill of drawing ovals is very well trained in detailed drawing of simple objects; the same roll of tape, for example, works great at first.

There is another common mistake when drawing ovals. Many people draw two arcs instead of an oval. This should not be allowed, even if your oval is very narrow; we always draw roundings in the corners.

Over time, you will become great at finding perspective in almost any object.

Well, after you get tired of circles, you can try drawing squares - the principle is the same. There is indeed a nuance with the vanishing point, but more on that another time.

I hope you no longer have problems with the circle in perspective and your drawings will be correct and accurate. In addition to this post, you can also see

Drawing circles of various diameters is far from the most necessary skill in life. However, sooner or later the need to draw a circle without a compass and other round-shaped auxiliary objects takes everyone by surprise. Therefore, it is better to find out in advance without a compass, regardless of its diameter.

How to draw an even circle without using a compass

You can be a schoolchild who came to a geometry lesson, forgetting his drawing tools, a student, an adult forced to draw a perfectly straight circle - different situations happen.

It will be useful for every person to know how to draw an even circle without a compass. We offer you several ways to solve this problem.

A compass can easily be replaced by another tool found in every student’s pencil case, namely a protractor. Place it on paper, marking the central point on the straight part, this will be the center of the future circle. Trace the inside of the semicircle, then rotate the ruler about ninety degrees and draw a third of the circle. Rotate the protractor one more time and complete the circle.

If you're in a meeting or at work and don't have the tool you need on hand, just use the CD. Trace it from the outside or from the inside to get a smaller shape.

In an office setting, you can also use a glass. To do this, take a glass of water, take a sip and place it on a sheet of paper, lightly circle the bottom. Drink some more and set it aside.

All of the above items can be found in any office; the protractor will also be available to students. With their help you can draw a circle evenly without a compass.

Draw circles of different sizes without auxiliary objects

What to do if you need to draw circles of different diameters?

It is not at all difficult to cope with this problem, having only paper and a simple pencil on hand.

Take a pencil in one hand and place the other on a piece of paper. Place the little finger of your first hand on the sheet so that it is the center of the future circle. Hold this position well. With your other hand, start turning the paper around your little finger. You will see how a smooth circle is obtained, just like when using a compass.

A larger circle is drawn in the same way, but in this case bend your little finger, as if you were clenching all your fingers into a fist. With your left hand, start turning the sheet until you see the resulting circle. It is advisable to use a pencil with a soft lead.

A circle with an even larger diameter can be drawn by repeating all the above tips, but now the right hand should touch the sheet with the protruding bone on the wrist.

These are the simplest methods on how to draw a circle without a compass. The most important thing in these methods is to learn to keep your right hand motionless (left if you are left-handed).

How to Draw a Perfect Circle Using a Ruler

If you have a regular ruler on hand, then you can use another tip on how to draw a circle without a compass. Take a ruler and place it on the paper, the "0" mark will be the center of the circle, so place it in the right place. Draw the second point near the digital value corresponding to the radius of the circle. Move the second edge of the ruler slightly so that the middle remains at zero, and the third point is located slightly above the second.

Do this procedure several times. As a result, you should have a circle drawn. The more often the dotted line, the easier it will be to connect everything into a solid line.

This is perhaps the easiest, but at the same time the longest way to draw a circle without a compass.

Any line, any stroke must express a certain form in the drawing. Thanks to strokes, lines are drawn, which, in turn, create various figures. Flat shapes have a rectilinear surface characterized by only two dimensions - length and width.

A square is a regular polygon, the axis of which is equal to four sides, and all four angles are right angles. Drawing a square on a small piece of paper with a pencil is not difficult, you just need to have a steady and confident hand. It is much more difficult to gain confidence when drawing a square in a large drawing. In such a case, charcoal is considered the most suitable drawing tool. Having calculated the size of the square, you should draw one of its vertical sides. Now from the top point of this straight line you need to draw a line perpendicular to it of exactly the same length. From the right point of this second line, draw a line perpendicular to it and parallel to the first. And finally, you need to combine the extreme points of two parallel lines.

The diagram below shows two squares, one larger (external), the other smaller (internal). Eight reference points are located on the symmetry axes of the large square. The vertices of the small square are located at a distance of two-thirds of the diagonals of the large square from its center. The vertices of a small square are united by smooth arcs, thereby forming a circle.

1. In order to draw a square, you need to know the length of its side.

2. From the top point of the vertical straight line, draw a line perpendicular to the first and equal in length to it.

3. Repeat the same action, finding the other top point of the square.

4. Finish creating the square by connecting parallel lines.

Rectangle

A rectangle is a regular polygon whose opposite sides are equal and all angles are right angles. When creating a rectangle, you need to perform the same steps as when depicting a square, but taking into account the difference in aspect ratio.

Circle

When creating a drawing, an indispensable tool, without a doubt, is a compass. In drawing, it is extremely important to learn how to draw without it. Until the skill of drawing a circle of the correct shape by hand has been formed, it is permissible to use some available means, for example, patterns or, as an improvised compass, even an ordinary cord. To achieve the goal, you can also mark reference points on two concentric squares.

How to draw a circle by hand

In order to learn how to draw a circle by hand, you should start practicing by creating small circles with a radius of about 5 cm. As a rule, at first the figures turn out to be somewhat oval in shape, then, as you gain practical experience, the circles take on the correct shape. To draw larger circles, it is advisable to mark reference points on two concentric squares or use a string to make the task easier.

It is not recommended to use a compass when creating drawings.

Practical advice: how to draw a circle using a cord

To develop the skill of creating the correct large circle, it is useful to use a cord.

1. With one hand, hold the tip of the cord at the point that will become the center of the circle. In your other hand, hold a piece of chalk and the other end of the cord at a distance that is equal to the radius of the circle.

2. Start drawing an arc from the point that will allow you to make the widest possible movement with the chalk.

3. To complete the circle, pass the hand holding the chalk under the hand holding the cord. At the same time, point your hand with the chalk in the opposite direction.

4. Make sure that the cord is kept at the same distance from the center of the circle, ensure that the beginning of the second semicircle is accurately connected to the end of the first.

The circle is also drawn using patterns. The simplest pattern can be the top of the glass.

Drawing a circle is not the most common task in life. It becomes even more difficult to gather your thoughts when you have to draw a circle by hand, without a compass, stencil or other auxiliary devices. But no one is immune from such a need. For some people more often, and for others less often, drawing a circle without a compass happens to everyone. For schoolchildren and students who forgot their cooking utensils at home. For parents of preschoolers who love to cut out “skirts” for cardboard dolls. Parents of schoolchildren who receive homework to make paper snowflakes. Housewives who regularly cover the bottom of the baking dish with suitable rounds of culinary parchment.

It’s easy to draw an even circle at home: take a plate, saucer or glass, place it upside down on paper and trace along the outline. How about drawing a perfect circle by hand? We bet the circle will look more like an oval, ellipse or polygon, depending on the precision of your coordination of movements? In the end, this is already a challenge to yourself. Will I be able to do such a trifle as drawing a perfect circle without a compass?! We know you can. If you practice and use a few tricks, you can draw an even circle without a compass and/or stencil, by hand.

What's the easiest way to draw a circle without a compass?
Forgetfulness is not a problem if you can compensate for it with resourcefulness. Let's say you left your compass at home while heading to a geometry lesson (on a topic related to circles) or a meeting (you urgently need to draw a visual pie chart). So that no one guesses about your absent-mindedness, gives you a bad grade or reprimands you, we offer you the following simple ways to draw a circle without a compass:

• Take a protractor from your pencil case (yours or your desk neighbor’s). This drawing instrument is famous for its versatility: it often replaces a ruler, and in the absence of a compass it will also perform its task. Place the protractor on the paper, placing the middle of its flat side at the point that will become the center of the future circle. Holding the protractor with your left hand, trace its rounded part with a pencil - this is half a circle. Now, being careful not to displace the center of the circle, rotate the protractor approximately 90° around the midpoint. Trace the rounded side again in a new location. Rotate the protractor on the paper to complete the circle and bring the pencil line to a full circle. In principle, you can draw a circle from two semicircles, but not all protractors allow this, so the three-step method is considered the most versatile and accurate.
  
• Even if there is no protractor nearby, you will have to violate the reputation of a diligent student and use an object that is not approved by all teachers: a CD. It will be easier for the manager at the meeting, because he will probably have a disk with a presentation or photos from a recent corporate event at hand. Place the disc on the paper and, pressing it with your left hand, trace it with a pencil with your right. If you need to draw a small circle, circle the disk not outside, but along the inner hole.
  
• Drawing a circle for a diagram by hand couldn't be easier! To do this, take an ordinary glass (glass or plastic disposable - it doesn’t matter), pretend that you want to wet your throat. Pour water into a glass (this will make it heavier and more stable), make sure that the bottom remains dry on the outside, and place it on a sheet of paper lying in front of you on the table. Now casually, without attracting too much attention and without making sudden movements, outline the bottom of the glass on the paper. Take another sip of water and place the glass away from the paper.
  

How to draw circles of different sizes without a compass?
To draw different circles without a compass evenly and beautifully, you will have to do without any aids: only paper, a pencil and the dexterity of your hands. But don’t be alarmed: it is the hands that can draw a circle without a compass. You can use these methods in almost any situation:

1. To draw a small circle by hand, literally, place a sheet of paper on a table or other flat horizontal surface, and take the pencil in your right hand in a normal motion. Bring your hand with a pencil to the paper and, slightly not completely lowering the lead onto the sheet, rest your little finger on the paper. The main condition: the little finger must press the sheet firmly against the table, but allow it to rotate around the axis, which is the point of contact of the pad of your little finger. Place the writing tip of the pencil on the paper and fix the position of the brush. With your other hand, rotate the sheet of paper around the little finger axis - and you will see how the stylus draws a perfect circle around it. A couple of tips: it’s more convenient to use a soft pencil (B or 2B) and cut your nails short.
   
2. To draw an even circle with a larger diameter, you will not need any other devices other than those listed in the previous paragraph. In the same way, take a pencil with a fairly soft lead with the fingers of your right hand. This time bend your little finger and press it against your palm, as if you were gathering your fingers into a fist. Lean on the crook of your little finger and repeat the previous technique. Rotate the piece of paper under your hand and hold the pencil still at a comfortable speed to create a neat circle. Manicure in this case no longer plays a big role. You can draw a medium-sized circle without a compass separately, or you can draw it around an already drawn small circle.
   
3. To draw a circle of even larger diameter, you can again use your own hands. The pattern of actions is repeated exactly until the moment of bending the fingers. But this time, lean not on your knuckles, but on the protruding part of your wrist. There is a protruding bone on the outside that will serve as an excellent support for your hand when drawing a circle. Hold the brush and pencil motionless in it, turning the sheet of paper on which an even circle of the desired size appears.
   

How to draw a large even circle without a compass?
It’s a little easier for schoolchildren, artists and office workers: their circles fit on small paper. But tailors and cutters have to work with larger surfaces, and circles are no less common in their work. The bottoms of panama hats and hats, the hems of sundresses and flared skirts - all these silhouettes are based on a circle. But this circle is often such that a compass commensurate with it simply does not exist. And this is how seamstresses came up with drawing circles without a compass:

1. First, determine which circle to draw by hand - that is, the radius of this circle. To do this, use a regular measuring tape to measure the desired area: waist circumference, head circumference or other parameter. Let's assume that this is a waist circumference of 60 cm.
   
2. The resulting number is the circumference. To find out the radius of a circle from the length, use the arithmetic formula: R= circumference/2∏. Accordingly, the radius of our circle will be equal to 60/2*3.14 = 60/6.28 ≈ 9.5 (cm). This is the radius of the circle that we have to draw by hand.
   
3. Take two pencils of the same length. Tie them with a strong thread, the length of which without taking into account knots (that is, the actual distance between the pencils when the thread is taut) is 9.5 cm. Place one pencil in the center of the future circle, and move the second one to the length of the thread.
   
4. Keeping the first pencil stationary, wrap the second in a circle, drawing a mark of the lead on the paper and maintaining the same thread tension throughout the entire process of drawing the circle.
   
5. Thus, we imitated the principle of a compass without having a compass to draw a large circle. The drawn circle is perfectly smooth and can be used to pattern a skirt belt.
   

How to draw a perfect circle without a compass
The main and perhaps only drawback of all the methods outlined above is the flaws in the circle being drawn. A circle drawn without a compass turns out to be approximately even, but not quite perfect, especially if you draw it in a hurry. There is a way to fix this problem. It will take a little more time, but you will be pleased with the result:

1. Take a piece of paper, a pencil and a ruler.
   
2. Decide what the radius of the future circle will be.
   
3. Place a dot on a piece of paper and mark it with a “0” mark on the ruler.
   
4. Place a second dot on the paper exactly next to the number indicating the radius you have chosen.
   
5. Move the ruler, place the “0” again on the starting point and place a second point according to the length of the radius.
   
6. Continue placing dots at equal distances from the center of the future circle.
   
7. As a result of these actions, you should get a circle drawn with a dotted line.
   
8. The more dots you put, the thicker the dotted line will be and the smaller the distance between its risks.
   
9. Connect the circle along the dotted line.
   

HOW TO CALCULATE THE RADIUS OF A CIRCLE.

What is it for, this radius calculation? To draw a circle, we need to know radius this circle - that is, the distance from one leg of the compass to the other.

Let’s say we need to draw the circumference of the bottom of a Panama hat, and all we know is the circumference of the child’s head. How wide should the legs of the compass be spread in order to ultimately obtain a circumference that matches the size of the baby’s head?

Or we need to draw the circumference of a circle skirt, knowing only that the circumference should perfectly match the circumference of our waist.

Now, so that everything is extremely clear and understandable, Let's look at 2 specific cases that are most often encountered in the work of seamstresses.

This is the calculation of the radius of the bottom of a Panama hat. And calculation of the radius on the circle skirt pattern.

So, let's go...

I beautifully painted this story in pictures directly with the text-reasoning. To make the whole sequence of brain work clear.)))

Means, to find out the radius, we need to divide our circumference of the baby’s head by 6.28.

We take a mobile phone, find a calculator in it and divide our 42 cm head circumference by 6.28 - we get 6.68 cm = that is, 6 cm and 6 mm. This is the radius.

This means that we need to move the legs of the compass apart to a distance of 6 cm 6 mm. And then the circle we drew will be equal to 42 cm - that is, it will lie evenly on the child’s head (just don’t forget to weigh it down by retreating 1 cm for seam allowances).

Situation two - you need to draw the circle of the circle skirt. All we know is the waist circumference and the length of the skirt that we ultimately want to get.

In the drawing of the sun skirt there are 2 circles. The small one (inner) should lie flat on our waist. That is, the length of this circumference should coincide with the waist circumference. The waist circumference is 70 cm, which means the circumference should be 70 cm (well, maybe there are all sorts of centimeters here and there in the form of seam allowance, or some other additional trim in the form of a belt or yoke)

This means we need to find out what radius to draw the circle so that the resulting circle is the length we need 70 cm.

In the picture below I have described everything and how to calculate the radius of a small circle and how to then find out the radius of a large circle.

And when a small circle is drawn. All we need is to add the desired length of the skirt to the small radius - and we get a large radius for the large circumference of the skirt edge.

Now we've sorted out the calculations. We will sew skirts and hats - I will send you to this article.

Now let's figure out how to draw a circle of any size without a compass.

HOW TO DRAW A CIRCLE WITHOUT COMPASSES.

Here below I have illustrated three methods with three pictures. I hope that everything is clearly drawn and written.

Yes, this is a quick way - but you need to make sure that the pencils do not move to the side. We change the angle of the pencil's radius. Or it is necessary for one person to hold one pencil exactly, and the other to draw exactly perpendicularly with a second pencil.

In general, the lower the thread is tied, the more accurate the circle will be. That's why some people use small pins. The error when the pin is tilted to the side is small, and can be neglected when sewing.

And yet, the surest way to draw an exact circle without a compass is with the help of an ordinary ruler and pencil. This is what it looks like:

And then in a circle, we move the centimeter (like the hour hand on a watch) and mark points at the same distance - that is, on the same number on the centimeter tape. Instead of tape, you can use string with a mark on it - the main thing is to make sure that the string does not stretch at all.

Well, that’s all - another gap in knowledge has been eliminated - now you can swing both a circle skirt and a Panama hat - we know how to calculate radii.
