Tip 1: How to determine the size of the head
Need to learn the size head occurs when buying a headdress. It is quite easy to determine it, but it is necessary to take into account at the same time what the measurement data is for. For example sports equipment: helmets, helmets, etc., should be a protection, therefore, sit on the head rather tightly. And, for example, a knitted cap or summer panama, on the contrary, should not constrain the head of its owner. Determining what you need to know the size head, you can start to measure.
You will need
- Centimeter tape, mirror, paper, pen.
Instructions
1
Take a centimeter tape or any flexible tape. Having made a mark on it, you can recalculate the data using the ruler.
2
To determine as accurately as possible the sizea head you need to wrap a centimeter tape at a distance of 1.5-2.5 centimeters above the eyebrows, just above the ears and pass through that point on the back of the head, which will give you the greatest circumference.
3
Further, if the circle is not sufficient to define the sizea, we measure the distance from the crown to the edgehead-dress in front (16 cm), rear (17 cm) and sides (21 cm). Remove the last measure (21 cm) from the crown of the temporal part. Then determine the distance from the earlobe to the middle of the nape (11 cm) (see the figure) (from M. Maximovoy's book "The Alphabet of Knitting" Moscow "Eksmo" 2005).
4
A centimeter tape should fit tightly to the head, but do not be taut.
5
Measurements are best done several times to get the most accurate data.
6
It should be taken into account for what purpose measurements are taken. For example, if the measurements are taken to buy a hat, or a helmet, that is, a thing that does not change its wear the size, then centimeter tape should be pulled the way you will wear this thing. When determining the same the sizeand pull the crochet cap centimeter tape tight, because the cap at the toe stretches.
7
The main source line for measurement is the rim line, which is equal to the circle head, hence, it determines the size headgear and is indicated on the label.

Tip 3: How to know the size of the head
When buying hats and hats, hats, helmets, wigs you need to know the size head. This is especially true when making a purchasethrough the online store. If the selected product does not suit you, you can exchange it. But in order to avoid unnecessary trouble, it is better to take maximum for this effort in advance.
You will need
- A centimeter tape, a table for converting measurements to size.
Instructions
1
There are different scales the sizes. In any case, your first step will be the same. Take a flexible centimeter tape, which is used by tailors and cutters. And measure the girth head. The ribbon should be positioned horizontally, approximately 2 cm above the eyebrows. The yardstick for measuring can be the way you are used to wearing hats.
2
Measure accurately, taking millimeters into account. The tape should fit snugly to the head. But it is impossible that she presses and stretches her head. In this case, the headpiece will behave the same way.
3
Then follow the instructions of the store where you order the hat. As a rule, they place a table of converting centimeters into the size. Or consult the store manager.
4
In Russia, a system is relevant in which complete, if necessary, rounded centimeters correspond the sizey. For example, girth head, equal to 55 cm corresponds to the 55th the sizey. The average female the sizeWe vary from the 54th to the 59th, the masculine - from 56th to 62nd.
5
In other cases, different the sizesystems adopted in other countries. They are marked in centimeters, inches or literal.
Tip 4: How to determine the size of socks
It would seem, socks, the most insignificant part of the wardrobe, which should not require as careful a choice as, for example, a dress or a suit. It turns out that it is very important to know them the size, unless, of course, you do not want to experience discomfort when walking: a heel or a sock may "fly off". But such small troubles are not needed by anyone. How to define the size socks yourself? After all, not every seller with a smile will give you a pair socks for fitting. This is not accepted, and not aesthetically pleasing. Therefore, there are compelling reasons to learn how to define the size socks, and once learning it, try never to forget.
You will need
- ruler
Instructions
1
The most reliable and proven way that exists from time immemorial is a sock wrapped around a fist. The heel should coincide with the toe.
2
A more reliable and accurate way to correctly determine your the size socks requires more time than the first option. You need to make a footprint on the sheet of paper, that is, draw it along the contour. You will need a ruler. Remember the long length. The work is done, left on the table (below) to find out your the size socks.
3
Measure the length from the tip of the thumb to the heel. Note: it is necessary to depict both feet, as usually the feet have different the size.
4
Remember the long length. Work is done, it remains for the table to know your the size socks.
5
Determining the length of the foot can not always be appliedto small children. Not all babies will dutifully measure their feet. There is one very good way. Using it, you will learn not only the length of the foot, but also its width, which will help you choose the most comfortable socks for the child. So, after bathing the leg of your child should be put on a piece of paper, there will be a wet trace, which you can sketch. By the way, this way you will understand the low or high rise of the foot of your baby. This is important to consider when choosing children's shoes. With all the rules, it's not difficult to make the right choice. And your legs will be comfortable.
Tip 5: How to determine the size at a distance
Any material objects that are in sight but out of reach have finite Dimensions, whether it's a tree in a field or a moon in the night sky. The question is how correctly to evaluate them - the distance distorts the idea of their true magnitude. There are several methods for determining the size of distance.
You will need
- - Theodolite;
- - Roulette;
- - calculator;
- - range finder;
- - ruler.
Instructions
1
The most accurate and fastest way to determine the size of an object on distance - with the help of a range finder. The effect of this device is based on determining the reflection time of the signal (active range finder) or calculating the distance to the object from the base and the parallax angle.
2
Measure the distance to the object with the range finder.
3
Hold the ruler in front of you in an outstretched hand and determine the size (height, width) of the object in millimeters.
4
Multiply the previously determined distance meterthe distance from the object (in meters) to the size of the object measured in millimeters (in millimeters) and divide this work by a constant coefficient of 6. The obtained value is the size of the object in centimeters.
5
The method of determining the dimensions of distance, based on triangulation or otherwise -parallactic displacement. Select two points on the terrain from which you see the object of interest. The result is a triangle whose vertices are the two selected points and the object of interest.
6
Measure the distance between the two points (the basis) and the adjacent angles with the theodolite.
7
Calculate the existing angles and the distance between the two points of the other two sides of the triangle formed by the object and the observation points. Using the distance, calculate Dimensions interesting subject on the previously given scheme.
8
And, finally, Dimensions celestial bodies. The dimensions of the stars are determined by their luminosity and temperature. Multiply the Earth's radius by the square root of the ratio of the luminosity of the star to the luminosity of the Sun. Multiply this number by the square of the ratio of the temperature of the sun to the temperature of the star. The value obtained is the radius of the star of interest.
9
Planet dimensions Multiply the distance to the planet inkilometers to the angle under which this planet is visible, and divide by 206265 - the value of 1 radian, expressed in seconds. This is the diameter of the planet of interest. Dimension: distance in kilometers, angle in seconds. The distance to the planet is calculated by a method similar to the method described above for determining the distance to an object on Earth. For celestial bodies the concept of horizontal parallax is used (the basis is the radius of the Earth).
Tip 6: How to know your helmet size
Many novice motorcyclists are faced with the problem of choice helmet. Despite the fact that some motor sport enthusiasts try to challenge the need for such a protective means, in many countries driving without helmet is considered a serious violation of the Roadmovement. Statistical data is collected both by supporters of the form of equipment, and by opponents. And they agree in one: to save a motorcyclist from a serious injury or even death can only properly selected helmet.
You will need
- - tape measure;
- - table of translation of dimensions.
Instructions
1
Measure the circumference of the head. This is done about the same as for the construction of the pattern of the headdress. Take a centimeter tape, attach a zero mark to the point located just above the left ear. Press the zero mark with your left hand, right circle the centimeter tape around the head - just above the eyebrows, above the right ear, over the occiput in the widest part of the skull. It is much more convenient to do these manipulations with someone's help. If the assistant is not around, stand in front of the mirror so that the line above the eyebrows is straight, and the dot above the right ear is just opposite to the one where you hold the centimeter.
2
Find the translation table sizes. In any decent store that sells likegoods, it is, but just in case, however, it will be seized. Head circumference 53-54 cm corresponds to the size of XS. If you have a size of 55-56 cm, the helmet should be marked with S. Letter M means the head circumference 57-58 cm. L (59-60 cm) and XL (61-62 cm) correspond to large dimensions.
3
Do not charge the purchase helmet to another person. You must try it on, even if you have identified the marking. Firstly, the sizes of helmets of different firms may vary, especially if the manufacturer is not very authoritative. Secondly, you can theoretically approach helmets of two relatives sizes, and which one to choose is up to you. Give preference to the one that is slightly smaller.
4
The helmet should sit tightly on the head. But at the same time, you must not allow squeezing. Do not forget that the slightest inconvenience can affect the management of the motorcycle. Accordingly, you run the risk of getting into a dangerous situation. Start measuring the helmets from the size you determined. If the crown does not touch the upper part, and you yourself feel uncomfortable, ask for a product slightly larger, but from the same manufacturer. He may not be. Then the helmets of the other company start measuring from the same size as you calculated. It may very well be that the first one will suit you perfectly.
5
Fasten the strap.Try it in this position to remove, pulling in different directions. First take the rear edge, lift and pull forward. Then grab the frontal part and pull back. The helmet must not be removed.
Tip 7: How to know the size of the headgear
Knowing the size head cleaning, you can buy a thing without fitting - for example,making purchases in online stores, or buying gifts for relatives and friends. Prepare a centimeter tape, sit comfortably in front of the mirror and put a pen and paper in front of you.
Instructions
1
Measure the volume of the head - wrap the softcentimeter tape around the head, leading it along the forehead, temples and the back of the head. Your measurements will be accurate if the tape passes through the frontal tubercles (a couple of centimeters above the eyebrow line), over the ears or wraps the occiput almost near the base of the neck. Do not stretch the centimeter tape too tight, but do not let slack. The resulting figure will match the sizeat the head.
2
If you do not have a centimeter tape, then use any soft tape - the indicators from it you can transfer to a regular ruler and calculate the size. When measuring the head, try to calculate the maximum circumference of the head, you may need to make several measurements, changing the position of the tape.
3
Match the indicators with the sizedifferent brands. Domestic the sizeThey accurately reflect the volume of the head in centimeters, but foreign manufacturers of hats adhere to their the sizenets. American the sizes, as well as international standard values the sizes, are denoted by Latin letters and correspond to a certain volume of the head in centimeters.
4
The biggest the size - XL, it corresponds to a volume of 59-60 cm. The smallest - S, is 53-54 cm. Between them are the most standard the sizes - L (57-58 cm) and M (55-56 cm). In European countries, you can find an indication of the volume of the head in inches - then you just need to convert inches to centimeters, multiplying by 2.54.
5
If you doubt the accuracy of the calculated indicator and can not choose the size at the time of buying head cleaning, then take the cap on the size more. So you protect yourself or another person from discomfort when wearing a tight cap - when squeezing the head there are very unpleasant sensations.
6
When calculating the sizebut consider the model head cleaning, which you are going to buy. If it's a knitted or knitted hat, then tighten the tailor belt tightly - the material will stretch slightly when worn. When purchasing a hat, pick up the size more carefully, it will be better if the tape does not sit tightly on the head, but will settle slightly more freely.
Tip 8: How to determine the size of a helmet
Since 2008, according to traffic rules, the helmetis a mandatory part of the equipment for drivers and passengers of motorcycles and scooters. It serves to protect the head during an accident. The outer part of the helmet protects against wind and dust, and the inner covering extinguishes the impact force and helps to avoid injuries. Therefore it is very important that the helmet fit you in size.
Instructions
1
Take a tape measure or a centimeter and measurethe head circumference is 1.5-2.5 cm above the eyebrows, just above the ears and across the back of the head at the base of the skull. Ask to measure your friends or relatives; it's very difficult to do it yourself. If you do not ask anyone for help, take the measurement in front of the mirror. Measure several times to avoid mistakes. Record the result, including millimeters. This will be your size.
2
Look at the helmet and find the size designation. It happens that the value you get falls between the standard values, for example, your value is 61 cm, and the marking is only 60 and 62. In this case, take a slightly larger volume, that is 62 cm. Some manufacturers indicate the marking of helmets in alphabetic form, for example , S corresponds to 56, M is 58, L is 60, XL is 62, and then larger or smaller size is determined by analogy with clothing.
3
Measure several helmets from different manufacturers. Even with the same size, different manufacturers will sit differently. Choose the most convenient. Correctly matched helmet should sit tightly on the head, not moving and not rotating when turning the head. Even with an unbuttoned strap, it should not fall off. The new helmet must be tightly dressed and just as tightly removed.
4
Having selected a suitable and convenient model beforego to the cashier, resemble it for about ten minutes and make sure that it does not rub or press. If at the end of this time you notice that some part of the head starts to break down - this helmet does not suit you. The helmet should not cause its owner any discomfort. It is not necessary to hope, that in due course it will be stretched, will be overcome and will take the form of a head.
5
Adjust the length of the strap, close the glass,turn your head. Compare which helmet will be easier to fasten, which helmet makes it easier for you to use the glass (visor). Give preference to the model that you will be most comfortable in sock and use.
