比得上 vs 比不上: the potential complements of comparison
比得上 and 比不上 are a pair of opposite potential complements derived from 比, meaning 'can compare to' and 'cannot compare to'. They are used to evaluate whether one person or thing is equal or superior to another. Unlike 比 itself, these forms focus on the outcome of the comparison, indicating the ability to match or the lack thereof.
比得上 and 比不上 are potential complements formed from the verb 比 (to compare) plus the resultative complements 得上/不上, which indicate the possibility of comparison reaching a level of equality or superiority. They are used to state that Subject A can (or cannot) measure up to Subject B in some aspect. Unlike the simple 比 construction, which just states a comparison, these forms explicitly evaluate the outcome: 比得上 asserts that A is at least as good as B, while 比不上 says A falls short.
When to use each
Use 比得上 to assert that one person or thing is at least as good as, or even superior to, another in a specific aspect. It is commonly used in affirmative statements to express that the subject can match the standard of the object. For example, 他的水平比得上专业选手 (His level can compare to professional players).
比得上 often carries a tone of confidence or pride, suggesting that the comparison is favorable. It is rarely used in negative sentences; its negative counterpart is 比不上.
Use 比不上 to indicate that one person or thing falls short of another, lacking the same level of quality, ability, or value. It is the negative counterpart of 比得上 and is used in both spoken and written Chinese to express inferiority. For example, 我的厨艺比不上妈妈 (My cooking skills cannot compare to mom's).
比不上 can be softened with adverbs like 远远 (far) or 还 (still) to emphasize the gap, e.g., 远远比不上 (far from comparable). It is also common in self-deprecation or humble expressions.

Common mistakes
- Using 不比得上 instead of 比不上 for negation: e.g., ✗ 他不比得上她 should be 他比不上她.
- Confusing subject and object order: e.g., ✗ 比得上他你 should be 你比得上他.
- Using 比得上 in a negative context without switching to 比不上: e.g., ✗ 我不比得上他 (should be 我比不上他).
- Overapplying 比不上 where 不如 would be more natural, especially before a verb phrase: e.g., ✗ 比不上他自己去 should be 不如他自己去.
FAQ
- When do I use 比得上 vs 比不上?
- Use 比得上 to assert that A can measure up to or exceed B, and 比不上 to state that A falls short. They are a positive-negative pair of potential complements, so you cannot interchange them.
- What is the difference between 比不上 and 不如?
- Both mean 'not as good as', but 不如 is more flexible: it can be followed by a verb phrase or clause (e.g., 不如他去), while 比不上 generally requires a noun or noun phrase as the object (e.g., 比不上他). 不如 also cannot be used in the positive sense like 比得上.
- Can 比得上 be used with 不 to form a negative?
- No. The correct negative form is 比不上. Using 不比得上 is a common mistake; it is ungrammatical.
- Is it possible to use 比得上 in a rhetorical question?
- Yes, for example, 他哪里比得上我? (How can he compare to me?) — this implies he cannot compare. The rhetorical tone inverts the meaning, but grammatically 比得上 remains positive.
