Macro and micro are near opposites of each other. We use “macro” to mean ‘large’ and “micro” to mean ‘very small.’
What is the difference between macro and micro?
One of the most common questions writers ask involves the words macro and micro. They differ by one letter and occupy similar terminology, such as “macrocosm vs. microcosm” or “macroeconomics vs. microeconomics.” Although these words seem complicated, we promise macro vs. micro is not.
The main difference between macro and micro is that “macro” means ‘large’ and “micro” means ‘extremely small.’ The terms are near opposites of one another, although “micro” tends to convey minuscule sizes, and “macro” can mean ‘relatively large’ instead of “giant.”
What does macro mean?
The word macro is an adjective, noun, or a combining form–– the latter originating from Greek makros for ‘long’ and ‘large.’ As noted by the New Oxford American Dictionary, the adjective and noun forms of macro developed independently of “macros-” (“Macro” 1049).
Macro as a combining form
As a combining form, the word macro allows any term to imply the essence of being “long,” “long-term,” “large,” “large scale,” or just “relatively large” in comparison to a standard size (in health care) (1049). For example, we use macro- for words like:
- Macroeconomics: ‘a branch of economics that involves large-scale economic factors, such as interest rates or national fiscal policy.’
- Macroevolution: ‘major biological evolution.’
- Macromolecule: ‘a molecule with several atoms.’
Macro as an adjective
The adjective macro describes something as ‘exceptionally prominent,’ ‘thick,’ or ‘large-scale.’ For example, photographers use macro lenses for macrophotography, where small objects are captured close-up enough to fill the entire photo. Sentence examples include,
- “Think of the Board as the ‘macro,’ credit-modulatory tier of our system.” –– Forbes
- “Macro-history gives us a big picture, but politics, as “Hamilton” reminds us, happens in hidden rooms.” –– The New Yorker
- “… immaculate teamfighting and macro decision-making takes care of business.” –– ESPN
- “‘Once it’s clear the epidemic is behind us, macro conditions will re-emerge.’” –– Forbes
Big, capacious, colossal, copious, enormous, global, huge, immense, jumbo, large, large-scale, massive, prominent, voluminous.
Macro as a noun
The noun macro (also known as “macro computing” or “macro instruction”) is an individual instruction that automatically expands into several other tasks or instructions. For example,
- “…Jio’s 4G network was a relatively traditional one, supplied by a single macro RAN vendor…” –– Fierce Telecom
What does micro mean?
The word micro also occurs in the English language as an adjective, noun, or combining form, where the latter originates from Greek mikros for ‘small.’
Micro- as a combining form
Micro- is a common combining form that allows any word to imply the essence of being ‘small’ or ‘reduced or restricted in size.’ However, we also find the prefix in titles of metric measurement, where micro- denotes a factor of one-millionth (10-6) (“Micro” 1104). Words containing “micro-” include:
- Microorganism: ‘an imperceivable small organism, such as a bacteria or parasites, that causes illness or fermentation.’
- Microeconomics: ‘a branch of economics that focuses on individual factors or decisions, such as an institution’s monetary policy, or their marketing strategy for a new product or price level.’
- Micron: ‘a unit of measurement approximate to one-millionth of a meter.’
Micro as an adjective

Diminutive, infinitesimal, invisible to the naked eye, mini, microscale, microscopic, minuscule, minute, nanoscopic, nanosized, reduced, tiny, very small.
Micro as a noun
As a noun, the word micro is short for “microcomputer” or “microprocessor.” According to Merriam-Webster’s Dictionary, a microcomputer is a small computer (often personal). Microcomputers often contain a microprocessor, a small (memory) processor on an “integrated-circuit chip.” For example,
- “Allen and Gates wrote a version of the BASIC programming language that could run on the Altair, then turned their collaboration into a company they called Micro-Soft.” –– Fast Company
- “In contrast, microcomputers had an unforeseen potential for privacy, individual use, and personal ownership of code.” –– The Atlantic
