Common Mistakes

I want a medium-sized coffee.
'medium-sized' is the compound adjective; 'medium size' is a noun phrase, not an adjective.
The town is medium size.

When used predicatively after 'be', the hyphenated form 'medium-sized' is still standard.

Synonym discussion

Sense: adjective/1

All four alternatives describe size that is neither small nor large, but they differ in nuance. 'Average-sized' implies typicality — something that represents the usual size for its kind — rather than simply being between two extremes. 'Mid-sized' is the most common choice in business and product contexts ('a mid-sized sedan', 'a mid-sized law firm') and sounds slightly more informal than 'medium-sized'. 'Moderate-sized' is less frequent in everyday conversation and carries a hint of formality or written style; it also tends to suggest that the size is reasonable or appropriate rather than just middle-range. 'Medium' used alone as an adjective ('a medium coffee', 'a medium bowl') is common but restricted to contexts where size categories (small–medium–large) are standard, such as food, clothing, or containers. In general writing, 'medium-sized' remains the safest and most neutral choice.

Etymology

LatinOld FrenchEnglish

The compound 'medium-sized' combines 'medium' (from Latin 'medius' meaning 'middle') and 'sized' (from 'size', which itself comes from Old French 'sise', a shortened form of 'assise' meaning 'a fixing of measure'). The adjective became common in English during the 19th century as trade and manufacturing created the need to describe goods that were neither small nor large.
