縮尺（しゅくしゃく、shukushaく）
- scale

The Japanese word 縮尺 （しゅくしゃく） primarily refers to the "scale" or "scale factor" used in maps, models, and drawings. It represents the ratio between the size of something on a representation (like a map or drawing) and its actual size in the real world. This ratio indicates how much the real-world object has been reduced or scaled down to fit on the representation. It essentially tells you how much smaller the drawn or modeled item is compared to the actual item. Think of it as a proportional relationship. A 縮尺 of 1:100 means that 1 unit on the map/drawing represents 100 units in reality. This concept is fundamental to understanding the relative sizes and distances in these representations.

⚫︎ 地図の縮尺は1:25,000です。 Translation: The map's scale is 1:25,000. ⚫︎ この模型の縮尺は1/50です。 Translation: The scale of this model is 1/50. ⚫︎ 設計図には縮尺が明記されている。 Translation: The scale is clearly indicated on the blueprint.

You use 縮尺 when discussing the size relationship between a representation (map, model, drawing) and the real thing. It's essential when reading maps, understanding architectural plans, or building models. You'll commonly see it written on maps and drawings to inform the user about the scale used. It’s also used when explaining the proportions of a model or when comparing sizes in different representations.

縮尺 is written using the kanji 縮, which means "to reduce" or "to shrink," and 尺, which is a unit of measurement (though in this context, it represents the "scale" or "measure"). The reading is しゅくしゃく (shukushaku) in hiragana. There is no other way to write this word. The okurigana is standard and doesn't vary.

There are no direct synonyms for 縮尺 in the same way as words like "scale" or "ratio" can be in English. However, words related to the concept include: ⚫︎ 比率（ひりつ）： Ratio, proportion ⚫︎ 割合（わりあい）： Percentage, proportion

There aren’t direct antonyms for 縮尺 in the same way as there are for other words. However, the opposite of the idea of reducing or scaling down would be enlargement or a larger size compared to the original, though there isn't a single word that directly means that in the context of maps and models.

この地図は、縮尺1:10,000で描かれています。 ・Translation: This map is drawn at a scale of 1:10,000. ・Explanation: This sentence explains the 縮尺 of the map, indicating that 1 unit on the map represents 10,000 units in the real world.

建築家は図面の縮尺を間違えてしまった。 ・Translation: The architect made a mistake with the scale of the drawing. ・Explanation: This sentence illustrates how a mistake in 縮尺 can lead to significant problems in practical applications, such as construction.

The word 縮尺 is formed from two kanji. 縮（しゅく） derives from the idea of "reducing" or "shrinking," highlighting the concept of making something smaller. 尺 （しゃく） signifies "measure" or a unit of length. Together, they accurately represent the concept of a scaled-down measure or the reduction of size in a drawing or model to a specific ratio. The combination emphasizes the relationship between the representation and the actual size.
