When do I use 得多 vs 多了 after an adjective in a 比 sentence?

Both are acceptable and mean 'much more'. 得多 is more formal and typical in writing; 多了 is colloquial and preferred in spoken Chinese. In everyday conversation, 多了 sounds more natural, while 得多 works in all registers.

Can 得多 ever mean 'more' in terms of quantity, like 多了 does?

No. 得多 strictly indicates degree ('much more' in comparison). To express an increase in quantity (e.g., 'three more books'), use 多了 after a noun or verb: 多了三本书, not *得多三本书.

Is 多了 always interchangeable with 得多 in comparative sentences?

In positive 比 + adjective sentences, they are usually interchangeable without change in meaning. However, 多了 is more emphatic and informal. In negative constructions or with verbs, their distributions differ: 多了 can follow verbs directly (吃多了), while 得多 cannot.

What is the difference between 多得 and 多了?

These are different structures. 多 + 得 + complement is rare (e.g., 多得多了? Actually not standard). The confusion is only between 得多 (degree complement) and 多了 (degree or quantity complement). 多得了 is not a standard pattern.

得多 vs 多了 (de duō vs duō le): much more in comparisons

Both 得多 and 多了 can follow an adjective after 比 to mean 'much more', but 得多 is more formal and strictly indicates degree difference, while 多了 is colloquial and can also mark a quantity increase. In comparative sentences they are often interchangeable, but 多了 carries a stronger spoken tone and can appear after nouns to indicate 'more'.

In Chinese, both 得多 and 多了 can be placed after an adjective (stative verb) to emphasize a large difference in degree, especially in comparative 比 sentences (e.g., 他比我高得多/多了 'He is much taller than me'). The core difference lies in formality and scope: 得多 is a purely degree‑focused complement used in formal and neutral contexts, while 多了 is more colloquial and can also follow a noun or verb to express an increase in quantity (e.g., 多了三本书 'three more books'). In 比 sentences, 得多 and 多了 are often interchangeable, but 多了 is preferred in spoken language.

Когда что использовать

得多dé duō

much more (degree)

Use 得多 after adjectives or stative verbs to indicate a large difference in degree, especially in formal or neutral contexts. It is the standard written form for 'much more' in comparative sentences with 比. It can also appear after verbs with 得 (e.g., 跑得快得多 'run much faster').

得多 cannot be used after a noun or verb without 得 to express a quantity increase; it is restricted to degree comparisons.

多了duō le

much more (colloquial); much more (quantity)

Use 多了 after adjectives in colloquial speech to emphasize a large degree, often implying a positive change or exclamation. It is also used after verbs or nouns to indicate an increase in quantity (e.g., 多了三个人 'three more people'). In comparative 比 sentences, 多了 is the natural spoken choice.

Although 多了 and 得多 overlap in 比 + adjective structures, 多了 is more emphatic and informal. In formal writing, prefer 得多.
