corresponding in size or amount
Having a size or amount that changes in the same way as something else.
Vzorec užití:
[something] is proportional to [something]
Častá chyba:
Learners often confuse 'proportional' with 'proportionate'. In most modern use, they are interchangeable in this sense, but 'proportional to' is far more common as a set phrase. Learners also sometimes say *'proportional with'* instead of the correct preposition 'proportional to'.
Synonyma
commensurate (More formal; often used with abstract nouns like 'salary', 'penalty', or 'responsibility'.)
|
corresponding (Emphasizes matching level or degree, not always strict numerical relation.)
Antonyma
disproportionate (Emphasizes that the size or amount does not match or is not appropriate in relation to something else.)
|

Synonyma

Antonyma

of fonts: variable character widths
Describes a style of text where thin letters like 'i' take less space than wide letters like 'm'.
Vzorec užití:

Častá chyba:
Learners may think 'proportional font' means 'correctly sized font' in a general sense. In computing and design contexts, it specifically refers to variable character widths, not just good or balanced sizing.
Synonyma
variable-width (Technical term in computing and typography that contrasts with 'fixed-width' or 'monospaced' fonts.)
Antonyma
monospaced (Describes fonts where every character has the same width, the opposite of proportional fonts.)
|
fixed-width (Another computing term meaning all characters take up equal horizontal space.)
