Learn English – Difference between “size” and “dimension”


What is the difference between nouns "size" and "dimension". When I want to set dimensions/sizes of an object which noun should I use?

Best Answer

You can find both words in most of dictionaries. As a physicist I would not use the word "dimension" in a daily life. For me, this is a mathematical term designated to a property of space. The noun "size" refers to geometrical properties of objects that surrounds us. Below are some daily meanings of the noun "dimension" from dictionary.com.

a. measurement in length, width, and thickness.

b. scope; importance: the dimensions of a problem.
