间 vs 套 (jiān vs tào): measuring single rooms vs complete dwellings
间 (jiān) is the measure word for individual rooms, such as bedrooms, classrooms, or offices. 套 (tào) is used for a complete set of rooms forming a single residential unit, like an apartment, house, or suite. The key distinction lies in counting discrete rooms versus the whole living space as a set.
间 and 套 are both measure words for spaces, but they apply to different levels. 间 counts individual rooms — any enclosed space like 卧室 (bedroom), 教室 (classroom), or 办公室 (office). 套 counts a complete dwelling consisting of multiple rooms — an apartment (公寓), a house (房子), or a suite (套房). Think of 间 as “single units” and 套 as “whole packages.” Note that 套 has broader uses for any set (e.g., 一套书), but when speaking about living spaces, it always refers to an entire residential unit.
When to use each
Use 间 to count individual rooms within a building: bedrooms, classrooms, offices, and other enclosed spaces. It is also used for counting shops (e.g., 一间商店) and for specifying how many rooms a property has (e.g., 三间卧室).
间 can also be a general classifier for rooms in a hotel or hospital, but never for the whole apartment or house unit itself.
Use 套 to count a complete residential unit that comprises multiple rooms, such as an apartment, a villa, or a hotel suite. It emphasizes the dwelling as an integral set. It also works for other complete sets, like 一套工具 (a set of tools), but in real estate contexts it is the standard measure word for homes.
套 does not count individual rooms; to say there are three rooms in a 套, use 间 for the rooms: 这套房子有三间卧室.

Common mistakes

- Using 套 for a single room: ✗ 我租了一套卧室 (should be 一间卧室).
- Confusing 间 and 套 when describing a hotel: a standard room is 一间房, a suite is 一套房.
- Trying to use 套 with 教室 or 办公室: ✗ 一套教室 (should be 一间教室).
FAQ
- When do I use 间 vs 套 for rooms?
- Use 间 for individual rooms like bedrooms, classrooms, and offices. Use 套 for complete residential units such as apartments, houses, or suites. If you want to say 'an apartment with three rooms,' you say 一套公寓有 (三个/三间)房间.
- Can 套 be used for things other than houses?
- Yes. 套 is also the measure word for any set of items that belong together, for example 一套书 (a set of books), 一套工具 (a set of tools), or 一套衣服 (a matching outfit). But when discussing housing, it always denotes a complete dwelling.
- How do I describe a house with multiple rooms? Do I use 间 or 套?
- You can use both, but in different ways. Use 套 for the house as a whole: 一套房子. Then describe the rooms inside with 间: 这 套 房子 有 三间 卧室 (This house has three bedrooms). Don't use 套 for the individual rooms.
- What about one-room apartments (studio)? Should I use 间 or 套?
- A studio apartment is a single room that serves as living, sleeping, and kitchen area. You can use either 一间 or 一套, but 一套 is more common for a self-contained dwelling. For example: 他住在一套小公寓里 is typical; 他住在一间公寓里 is also understood as a single-room unit.
