Tennis courts are usually divided into areas by white lines. The white line defines where the ball lands. Each line has a unique name such as a base line or a service line. (Refer to this corner, #939 ‘Why do we say ‘baseline’ in tennis’, ‘Why do we say ‘service line’ in this corner?) The ‘center line’ perpendicular to the net is the line that divides the service line and the side line into two halves in the middle. The serve is considered an important line along with the service line because it must land on the inside of the service line and the center line to score points.

In tennis, the center line is not translated as the center line in Korean, but is pronounced as it is pronounced in English. The center line is a compound word of ‘center’ meaning middle and ‘line’ meaning line. According to the English Glossary, the word center in sports was used a lot in the 19th and 20th centuries. This word originally came from the French ‘centre’ at the end of the 14th century and is rooted in the Latin ‘centrum’. It was used as a word meaning the middle point of the circle, the center of things. In baseball, the defender in charge of the middle of the outfield is called ‘center fielder’, and in soccer, the forward striker is called ‘center forward’. Since the invention of basketball by James Naismith in 1891, the center has been operated as a key position along with guards and forwards. In American baseball, it is said that the term center was used in 1864토토사이트. (Refer to the 400th episode of this corner, ‘Why do I say ‘Center’?)

Centerlines have been used in Korean media since the days of Japanese colonial rule. On March 29, 1925, the Chosun Ilbo, an article titled ‘Change of Tennis Rules (庭球規變更)’ reads, ‘The British Tennis Association (UK) reported on the General Assembly of the International Softball Federation (國際庭球聯盟總會) held in Paris. According to the announcement, the representatives of the 16 countries must attend the annual general meeting, and consultations were held and Oh Tae-ri Li) Equator, India, Aeran, Hongai, etc., join the federation, and then the US representative (米國代表) is the British representative ( Proposal to insert the left and right three terms in the “Fold Fold rule” in the six-point rule of the tennis court rules.

Tennis courts were not originally rectangular. Introduced in 1874 by British Army Major Walter Wingfield as tennis, the court was hourglass-shaped with a net 5 to 7 feet high. In 1877, while preparing for the first Wimbledon Championships at the All England Club, the current rectangular court was created. In 1882, net height was reduced to 3 feet, and various lines similar to today’s were established.

The center line is drawn halfway down the middle of the court and divides the court into two halves on either side. Server lines and center lines on both sides subdivide each side of the court into four areas. The court near the net is called the service court. The center line and center mark should be 5 cm wide, and all other lines should be 2.5 cm to 5 cm wide, but only the base line may be 10 cm wide. All court measurements are taken from the outside of the line, so the line corresponds to the inside of the court. Therefore, all balls that land on the line are ‘in’ and become effective hits.
