## How to determine head size

This parameter is the main one when choosing a hat, hat or cap.

### Soft tailor's tape or lace and ruler (tape measure)

#### What to do

Wrap a measuring tape around your head - through the middle of the forehead (about 2 cm above the eyebrows) and the most prominent part of the back of the head.

Fix the mark at which the meter closed.

If there is no tailor's tape, use a lace: wrap it around your head in the same way, and then find out the length of the resulting segment using a ruler.

In order not to be mistaken, repeat the measurements two or three times and print the arithmetic mean.

### Round off the resulting number if necessary

Ideally, if the whole number came out: this is how the standard Russian and European sizes are marked, and there will be no problems with the selection of the cap.

If the number is fractional, it must be rounded. Which way depends on the type of headdress that you plan to buy.

• Knitted or crocheted hat. Round down to a smaller whole, because these hats stretch well. Subtract one more from the resulting size if you want the model to sit tighter. The same rule applies to hats with a voluminous pattern or "loose": over time, they stretch even more than usual.
• Cap, baseball cap, hat made of hard, inelastic material. Round towards a larger whole. When in doubt which of the two sizes to choose, it's best to stick with the larger one. For example, if you have a head circumference of 57.8 cm, the nearest larger integer is 58. If you are worried that a cap of the 58th size will be right next to it, take the 59th.

### Compare the resulting integer with the size chart

There are three common systems in which the parameters of hats in different countries are denoted: centimeter, inch and letter.

1. Centimeter. Used in Russia and Europe. The size in this system is equal to the head circumference in centimeters.
2. Inch. Applicable in the UK and USA. The size corresponds to the head circumference in inches.
3. Literal. It is a generally accepted international system that uses descriptive abbreviations: XS - extra small, very small; S - small, small; M - medium, medium; L - large, large, and so on.

There is a rigid connection between the dimensional grids. Therefore, if you know the head circumference in centimeters, you can easily determine your size in any of the systems.

 Head circumference in cm Russian and European size UK and US size International size 53–54 53–54 6¾ (21.2 inches) XXS 55 55 6⅞ (21.6 inches) XS 56 56 7 (22 inches) S 57 57 7⅛ (22.4 inches) M 58 58 7¼ (22.8 inches) L 59 59 7⅜ (23.2 inches) XL 60–61 60–61 7½ – 7⅝ (23.6–24 inches) XXL 62–63 62–63 7¾ – 7⅞ (24.4–24.8 inches) XXXL 64–65 64–65 8-8⅛ (25-25.6 inches) XXXXL

### Determine planting depth

This is a minor parameter, but in some cases it is also important. The hat can be perfectly matched to the circumference of the head. But it will not sit as you would like if the depth is not enough or too much.

#### What is needed

• Soft tailor's tape measure.
• Pen and a sheet of paper for writing.

#### What to do

If you want the hat to fit snugly against your head and not completely cover your ears, measure the length of the longitudinal arc. This is the distance from the back of the head to the middle of the forehead.

If you need the hat to completely protect your ears from the cold, determine the length of the transverse arc - from temple to temple through the crown.

Divide the selected and found value by two, and you will get the planting depth. This height should be a folded hat.

Find the planting depth of the model you like in the product description or ask the seller to measure this parameter separately. Compare with the figures obtained.
