How big is the photo on the tombstone?

The photo on the tombstone is 1 inch or 2 inches. A tombstone is a stone tablet standing in front of or behind a grave, engraved with the name, deeds and photos of the deceased. The photo is 1 inch or 2 inches, which is in harmony with the proportion of the main monument to facilitate relatives and friends to mourn better. Tombstones originated from ancient "monuments" used to tow coffins for burial. The name "monument" first appeared in the Spring and Autumn Period. Originally, it refers to vertical stones or piles without words, such as tied sacrificial tablets, which are used to tie cattle, sheep and other livestock in front of ancestral temples during sacrificial activities, and a shadow measuring tablet, which is used by the court to measure the time of the day according to the changes of shadows projected in the sun. The tablet is made of a thick board in the shape of a tablet, and a round hole is cut at the upper end, which is called "piercing". A crossbar is placed between the two pillars, and a rope is wrapped around the wood, which can be used to put the rope, like a pulley.
