Synonyms & antonyms
  • Synonym倍増ばいぞうNeutralNeutral and more common than 「倍加」; refers to increasing to about twice the amount, favoring concrete figures like 「売上倍増」.
  • Synonym倍するばいするWrittenWritten/formal prose; mostly in the pattern 「〜に倍する」, meaning double in comparison with something; strongly literary flavor.
  • Antonym半減はんげんNeutralNeutral; reduction by half, the counterpart of doubling with 「倍加」; also said of fun or charm being halved.
  • Antonym減少げんしょうNeutralNeutral; a general word for decrease, not limited to any proportion, running opposite to 「倍加」's marked increase.

For quantities that double, 「倍増」 is the usual choice. 「倍加」 leans written/formal and often describes a big rise in degree, as of burden or fun. The opposite of doubling is 「半減」; for decrease in general, use 「減少」.
