The easiest way to know the right necklace size is to measure an existing necklace or pendant that suits you. A tape measure will be very useful. Untie the chain and straighten it when measuring. Put it on a table or flat surface so that it is easy to measure. If you don't have a necklace on hand, it's also not difficult to know the size of the necklace that suits you.
Measure Your Neck Size
The measurement of neck size is very important to determine the appropriate length of the necklace. When measuring, use a soft tape around your neck and keep the tape parallel when measuring. Then, add 2 to 4 inches (5 to 10 cm) to your neck size to calculate the minimum chain length that suits you.
If your neck size is between 13 inches (33 cm) and 14.5 inches (36.8 cm), an 18-inch (45.7 cm) necklace is a good choice.
If your neck size is between 15 inches (38 cm) and 16.5 inches (41.9 cm), it is recommended to choose a necklace of 20 inches (50.8 cm).
If your neck size is 17 inches (43.2 cm) to 18.5 inches (47 cm), you can choose a 22-inch (55.9 cm) necklace.
Height is also a factor to consider when choosing the necklace length. In addition to the size of the neck, your height will also change the position of the necklace when wearing. Long necklaces can overwhelm short people, and tall people are not suitable for short necklaces.
If you are less than 5 feet 4 inches (162 cm) tall, wear a necklace of 16 to 20 inches (40 to 50 cm).
For people between 5 feet 4 inches (162 cm) and 5 feet 7 inches (170 cm) tall, necklaces of any length will look great.
People who are 5 feet 7 inches (170 cm) tall or taller can also wear necklaces of any length, but long chain necklaces are best for tall people because they accentuate the taller figure.
Choose a necklace size that suits your body shape. Just as different clothes can bring out different parts of the body, different necklace lengths will also highlight different parts of the body, because people's eyes will stop at the end of the necklace. If you want to highlight a certain part of the body, try choosing the right length by the end of the necklace in that position.
If you are small, a short and thin chain is a good choice. If you have a fuller figure, a slightly longer and thicker chain will look better. Full-bodied women should avoid wearing necklaces below the breast line. You can try wearing a slightly shorter necklace, such as an 18-22 inch necklace.
Some necklace sizes can be used to modify the shape of the face.
A necklace with a length of 10 to 16 inches (25.4 to 40.6 cm) helps soften the chin of people with heart-shaped faces. This method is also suitable for those with rectangular faces.
People with round faces should avoid wearing short necklaces or chokers, as these necklaces will make the face look rounder. A long necklace of 26 to 36 inches (66 to 91.4 cm) can lengthen the chin better.
People with long faces can choose to wear shorter necklaces to modify their faces, such as chokers and princess necklaces that are between 16 inches and 18 inches in size. A short and round necklace will not make the face look longer.
If you have an oval face, then wearing any shape, length or type of necklace will be charming.
