多益單字要背多少？依分數級距整理的 6,730 個單字How many words do you need for the TOEIC? 6,730 words by score band
印帳把 6,730 個多益常用單字分成 450、600、730、860、900+ 五個級距。這篇整理每個級距的字數、選字依據，以及怎麼用這張表規劃讀書進度。Stamp Ledger groups 6,730 common TOEIC words into five score bands. Here are the word counts per band, where the words come from, and how to use them to plan your study.
準備多益時，最常被問的是「要背多少單字才夠？」ETS（多益主辦單位）並沒有公布各分數對應的單字量，市面上的數字大多是各家的估計。以下是「印帳多益單字Stamp Ledger」整理單字時採用的分級，以及每個級距收錄的字數，給你規劃時參考。
各級距收錄多少字
| 分數級距 | 這一級的字數 | 累計（含以下級距） |
|---|---|---|
| 450 | 1,682 | 1,682 |
| 600 | 2,246 | 3,928 |
| 730 | 1,622 | 5,550 |
| 860 | 875 | 6,425 |
| 900+ | 305 | 6,730 |
600 分這一級的字最多，大多是日常商務情境常見的字。分數越高，每一級新增的字越少，也越專門。
這些字是怎麼選的
選字依據四份公開的英文常用字表：
- NGSL（New General Service List）：一般英文最常用的字
- TSL（TOEIC Service List）：多益常用字
- BSL（Business Service List）：商務英文常用字
- NAWL（New Academic Word List）：學術英文常用字
這些字表由 Charles Browne、Brent Culligan、Joseph Phillips 等人編製，以 CC BY-SA 4.0 授權公開。印帳在這個基礎上，另外編寫詞性、繁體中文意思、例句與分級。
怎麼用這張表規劃
- 先知道自己在哪一級：可以用最近一次的成績對照；不確定的話，印帳有 2 分鐘入門測驗，會幫你設好級距。
- 以目標分數的那一級為主力：例如目標 730 分，主力是 730 級的 1,622 個字，同時把 450、600 級還不熟的字補起來。
- 用間隔複習記住，不要一次背完：做法見〈間隔複習是什麼？〉。
單字量只是多益的一部分，聽力、閱讀速度和文法一樣重要。這張表是讓你知道「單字」這一塊大概有多大的範圍。

“How many words do I need?” is one of the most common TOEIC questions. ETS, which runs the TOEIC, doesn't publish vocabulary sizes for each score, so most numbers you'll find are estimates. Here is how Stamp Ledger groups its words by score band, and how many words each band contains.
Words per score band
| Score band | Words in this band | Cumulative |
|---|---|---|
| 450 | 1,682 | 1,682 |
| 600 | 2,246 | 3,928 |
| 730 | 1,622 | 5,550 |
| 860 | 875 | 6,425 |
| 900+ | 305 | 6,730 |
The 600 band is the largest, mostly everyday business vocabulary. Higher bands add fewer, more specialised words.
Where the words come from
The selection is based on four open word lists: the NGSL (New General Service List), TSL (TOEIC Service List), BSL (Business Service List) and NAWL (New Academic Word List), by Charles Browne, Brent Culligan, Joseph Phillips and others, released under CC BY-SA 4.0. Stamp Ledger adds parts of speech, Traditional Chinese meanings, example sentences and the score bands.
How to use it
- Find your band from a recent score, or take Stamp Ledger's 2-minute placement test.
- Focus on your target band. Aiming for 730? Focus on its 1,622 words while filling gaps from the 450 and 600 bands.
- Use spaced review instead of cramming. See What is spaced repetition?
Vocabulary is only one part of the TOEIC; listening, reading speed and grammar matter too. This table shows roughly how big the vocabulary part is.
