Mastering Korean numbers from 1 to 100 unlocks everyday interactions, from counting items at a market to reading prices on store shelves. This practical guide breaks down the essential rules and patterns so you can build confidence using Korean numerals in real situations.
Clear number formation is the foundation of Korean language fluency, helping you express dates, quantities, and measurements accurately. The following sections organize key insights into memorable structures you can use right away.
| Number Range | Korean Hangul | Romanization | Notes |
|---|---|---|---|
| 1 to 10 | 일, 이, 삼, 사, 오, 육, 칠, 팔, 구, 십 | il, i, sam, sa, o, yuk, chil, pal, gu, sip | Basic set; 십 (sip) means ten |
| 11 to 19 | 십일, 십이, 십삼, 십사, 십오, 십육, 십칠, 십팔, 십구 | sibil, sibi, samsa, sisa, sibo, siyuk, chilb, palb, sibgu | Attach units directly after 십 |
| 20 to 99 | 이십, 삼십, 사십, 오십, 육십, 칠십, 팔십, 구십 | isib, samsib, sasa, osib, yuksib, chilsib, palsib, gusib | Tens unit followed by optional unit with space |
| 100 | 백 | baek | One hundred; combine with tens and ones |
Counting Fundamentals 1 to 10
The first ten Korean numbers form the building blocks for everything larger. Each word has a distinct sound and stroke order, making early practice critical.
Memorize these in order: 일 (1), 이 (2), 삼 (3), 사 (4), 오 (5), 육 (6), 칠 (7), 팔 (8), 구 (9), 십 (10). Practice saying them aloud while writing to reinforce pronunciation and visual shape.
When you are comfortable, move quickly to combinations like twelve (십이) or nineteen (십구), because the logic of combination stays consistent beyond ten.
11 to 19 Logical Patterns
Numbers 11 to 19 in Korean follow a predictable template of 십 (ten) plus the unit. Instead of creating new words, the language attaches the smaller number directly after 십.
For example, 13 is 십삼 and 18 is 십팔. Notice that optional short pauses or connectors are usually omitted in speech, so 십팔 sounds like a single flowing word even though it combines two elements.
Drilling these combinations until they feel automatic will speed up your ability to understand dates, addresses, and quantities in everyday Korean.
Tens and Numbers 20 to 99
Once you pass 19, Korean numbers shift to a tens-unit structure. You state the tens digit first, then optionally add the ones digit with a light pause or no break at all.
Examples include 이십 (20), 어른 삼십 (30), and 오십 칠 (57). For numbers like ninety-nine, the pattern is 구십 구 (90 9), demonstrating how the system scales efficiently up to 99.
Mastering this structure lets you handle bus numbers, prices, and street addresses without relying on translation tools in daily life.
Number 100 and Simple Combinations
The word for 100 in Korean is 백, and it combines cleanly with tens and units. For instance, 101 is 백 일 and 234 is 이 백 삼십 사.
When 백 appears in the middle of larger numbers, pronunciation can shift slightly due to Korean sound rules. Listening to native speakers and repeating patterns will help your mouth adapt to natural speech rhythms.
